Spectroscopic Studies on Molecular Configurations of Some Aliphatic Dinitriles. II. Infrared Spectra of Glutaronitrile and Bis(glutaronitrilo)copper(I) Nitrate
Authors: Matsubara Ikuo 
Published: July 2006

Abstract
The infrared spectra of glutaronitrile and bis(glutaronitrile)copper(I) nitrate, [Cu{NC–(CH2)3–CN}2]NO3, have been studied. the spectrum of the complex has been analysed on the basis of the result of X-ray analysis which disclosed that the ligand glutaronitrile takes the GG configuration in the crystals of this compound. This complex reacts with alkali halides such as free glutaronitrile. Considering the frequency shifts of the nitrate vibrations the reaction of the complex with potassium bromide should be ascribed largely to an ion interchange between the two phases. The increase of 29 cm−1 in the C≡N streching frequency by complex formation may be understood from the linear structure of the Cu-N-C-CH2 group which suggests that the carbon-nitrogen bond is essentially of a triple-bond character, the contributions of polar resonance structures such as –C+=N− being decreased. Glutaro-nitrile can form two different crystaline solid phases, depending on the mode of crystallization. From comparison of the two solid-state spectra with that of the complex and from consideration of the vibrational selection rules it has been concluded that glutaronitrile takes the GG configuration in one crystalline solid state and the TG in the other, and that it exists as a mixture of three isomers, GG, TG and TT in the liquid state. Calculation of the skeletal defornation frequencies for each isomeric form has given the results which support this conclusion. Vibrational assignment of glutaronitrile in various states has been made satisfactorily on the basis of the above results.

Published: July 2006

Abstract
Homopolymers of N-carboxy-dehydroalanine anhydride (I) and of N-phthaloyl-dehydroalanine (II), and copolymers of II with vinyl acetate were synthesized. Hydrolysis or hydrazinolysis was carried out to obtain polymers containing α-amino acid structures. Actual structures of these polymers were discussed.
Thermodynamic Studies on Cobalt Complexes. IX. Chemical Equilibrium between Diaquotetramminecobalt(III) Complex and Oxalate Ion
Authors: Mori Motoshichi , Tsuchiya Ryokichi , Matsuda Eisei 
Published: July 2006

Abstract
The equilibrium of the reaction, [Co(NH3)4·(OH2)2]3++C2O42−=[Co(NH3)4C2O4]++2H2O (1), was measured spectrophotometrically and the free energy of formation of oxalatotetramminecobalt(III) ion was calculated. The large increase of the entropy for the above reaction was interpreted by the chelate effect of oxalate ion.
When the mixture of oxalic acid and potassium oxalate reacts with diaquotetramminecobalt(III) complex, oxalate ion is coordinated as a bidentate ligand, whereas it is coordinated as an unidentate ligand when ammonium oxalate reacts with the same diaquo-complex.
Visible Absorption Spectra of 1,3,5-Trinitrobenzene and its Derivatives in Aqueous Alkaline Acetone
Authors: Abe Takehiro 
Published: July 2006

Abstract
The visible absorption spectra of the colored solutions produced by adding aqueous sodium hydroxide solution or ammonia water to the acetone solutions of 1,3,5-trinitrobenzene and its derivatives (2,4,6-trinitrotoluene, tetryl and picryl chloride) were measured at room temperature in order to investigate the difference of the chemical actions between stong-alkaline sodium hydroxide and weak-alkaline ammonia water.
These trinitro compounds in acetone containing sodium hydroxide show spectra similar to that of the aqueous sodium hydroxide solution of tetryl. The spectrum of this aqueous colored solution is considered to be due to an intermediate of the Meisenheimer type in the process of the substitution reaction of tetryl to picric acid. Consequently, all the spectra of the colored solutions from the trinitro componds are also probably due to the intermediates ot the Meisenheimer type.
Each colored solution of the trinitro compounds in acetone containing ammonia water initially shows the same spectrum as that with sodium hydroxide, except for the case of trinitrotoluene, and changes to the other colored solution having an intense and stable band entirely different from the initial spectrum. The initially formed colored solutions of these trinitro compounds, except the solution from trinitrotoluene, may also be due to the Meisenheimer intermediates.

Authors: Mori Motoshichi , Shibata Muraji , Hori Kuniko 
Published: July 2006

Abstract
Additional elution experiments for confirming the fact that the trans ions of the diacidotetrammine-type complexes are always eluted faster than the corresponding cis ions have been performed by using several diacido-type complexes which are relatively unstable. By comparing the elution maxima for the whole complex ions which have been used to date, the relative adsorbabilities of the isomeric ions on a cation exchanger have been predicted as follows:
For the trans ions,
[Co en2(NCS)2]+&lt;[Co en2(NO2)2]+\simeq
[Co en2Br2]+&lt;[Co en2Cl2]+\simeq
[Co en2NO2Cl]+&lt;[Co(NH3)4(NO2)2]+&lt;
[Co en(NH3)2Cl2]+
For the cis ions,
[Co en2Cl2]+&lt;[Co en2(NCS)2]+&lt;
[Co en(NH3)2Cl2]+\simeq[Co en2NO2Cl]+&lt;
[Co en2(NO2)2]+&lt;[Co(NH3)4(NO2)2]+

Visco-elastic Behaviors of Aluminum Soap-Hydrocarbon Systems. I. Aluminum Stearate in Nujol
Authors: Shiba Sukekuni 
Published: July 2006

Abstract
Dynamic visco-elastic behaviors of the aluminum stearate nujol system were studied, using a concentric cylinder type forced oscillation rheometer. The system behaves always as a typical visco-elastic body in a wide range of concentrations and temperatures, and manifests conspicuous amplitude and frequency dependence, which indicates non-linear visco-elastic properties. Wedge type relaxation spectra of the system were obtained, and it was found that the system is thermo-rheologically simple in a confined region of temperatures. The time effect of the specimen and temperature dependence of dynamic properties were examined, and the rheological structures in the system under various conditions were discussed.
Studies on Mass Spectra and Appearance Potentials of Acetic Acid and Deuteroacetic Acid CD3COOH
Authors: Hirota Kozo , Nagoshi Kazuo , Hatada Motoyoshi 
Published: July 2006

Abstract
In order to obtain information on the decomposition process of acetic acid in radiation chemistry, not only mass spectra of both acetic acid and deuteroacetic acid but also appearance potentials of parent and main fragment ions of both acids have been measured.
By studying the effects of ion source temperature and of electron accelerating voltage on the spectra, and by comparing the mass spectra of both acids, it has been possible to identify the chemical species produced by electron impact without ambiguity and also to estimate the process of their production to some extent.
It has been found that, although the appearance potentials of the parent ion of both acids coincide fairly well, those of CH3+ and COOH+ from CH3COOH are higher than those of corresponding ions from deuterated acid. The breaks of ionization-efficiency curves have been observed in CH3+ and CD3+ ions at about 6 volts higher than the appearance potentials suggesting a possibility of the presence of an excited state of the product ions.
The Resonance Effect of Amide Group on the Polymerizability of Lactam Derivatives. I. The Infrared Spectrum of N-Methyl Lactams
Authors: Ogata Naoya 
Published: July 2006

Abstract
The infrared spectra of several N-methyl lactams and acid amides have been measured in chloroform solution in order to investigate the correlation between the polymerizability of lactams and the frequencies of the carbonyl absorption of the amide group. The observed frequency lowering of the amide I band by N-methyl substitution can be related to the increasing contribution of the ionic structure to the resonance in the amide group, and to the low polymerizability. The infrared spectra of N-methyl lactams exhibit doublets or triplets in the carbonyl stretching region.

Studies on the Mucilage of the Root of “Tororo-aoi” (Abelmoschus manihot, MEDIC). III. On the Mechanism of the Characteristic Colloidal Nature of the Mucilage
Authors: Inokawa Saburo 
Published: July 2006

Abstract
1) The colloidal characteristics of the mucilage from “Tororo-aoi” such as the elasticity, spinnability, and so on are caused by the network built by interlocking between short branched chains of the mucin molecules, fibrous glucosans and proteins.
2) The remarkable change of the colloidal nature by heating is caused by breaking down the interlocking by oxidation.
The Effect of Alcohols on the Solubilization of Oleic Acid in the Aqueous Solution of Sodium Dodecyl Sulfate
Authors: Matuura Ryohei , Furudate Kazuo , Tsutsumi Hidetoshi , Miida Seido 
Published: July 2006

Abstract
The solubilization of oleic acid in the aqueous solution of sodium dodecyl sulfate was studied in the presence of various kinds of alcohols in various concentrations. When the concentration of alcohols in the detergent solution is not so great, the solubility of oleic acid decreases as the amount of alcohols increases. This is explained by the solution of oleic acid and alcohols in the same place in the micelle, i. e., in the palisade layer. When the water soluble alcohols are used the solubilization of oleic acid turns out to increase at a certain concentration of the alcohols in the detergent solution. This is explained by the solution of oleic acid in the solvent liquid as well as in the detergent micelles.
The Effects of Various Spinning Processes on the Fine Structure of Viscose Rayon Staples (Distribution of Chain Length of Oxidizing-hydrolyzed Residue)
Authors: K\={o}shiro Taketoshi , Fujimura Toshikazu 
Published: July 2006

Abstract
The fractionation of oxidizing-hydrolyzed residue was applied to study the fine structure of various types of rayons.
It was assured that tirecord, high-tenacity rayon spun in high zinc percent Muller’s bath, Toramomen and ordinary rayon have one sharp peak in each crystalline size distribution curve and smaller crystallites than Lilienfeldt-type rayon which shows two peaks in the crystalline size distribution curve.
The alkali-treatment of Lilienfeldt-type rayon increases not only its crystallinity but also the crystalline size, probably owing to the fusion of two adjacent crystallities.
There can be a correlation between the crystalline size distribution by oxidizing-hydrolysis and the lateral-order distribution; namely, the higher lateral-order portion may consist of the longer crystallite.
The carboxyl group in the oxidizing-hydrolyzed residue increases rapidly in the initial stage of hydrolysis and then decreases to an equilibrium value. The apparently lower accessibility by iodine sorption may be due to the negative carboxyl group remaining.
On the Reaction of Aromatic Dinitriles and Formaldehyde
Authors: Tachikawa Toshihisa 
Published: July 2006

Abstract
1. Like aliphatic dinitriles, polyamide having benzene nucleus and -CONH- linkages was synthesized by condensation polymerization reaction of aromatic dinitriles and formaldehyde in concentrated sulfuric acid.
2. The condensation polymer obtained from terephthalonitrile had the greatest intrinsic viscosity among ortho-, iso-, tere-phthalonitrile and p-xylylene cyanide. A product of the highest condensation polymerization degree was obtained, by adding the 1.025: 1 molar mixture of paraformaldehyde and terephthalonitrile in small portions into ten molar amounts of 95% sulfuric acid at 0°C and then stirring for ten hours at the same temperature.
3. These condensation polymers were insoluble in almost all organic solvents and had no melting and softening point. They decomposed above 300°C.
Polarographic Investigations of Vitamin C. III. Reduction Waves of the Condensation Products of Dehydro-l-ascorbic Acid and its Related Compounds with o-Phenylenediamine. Application to the Simultaneous Determination of l-Ascorbic Acid, Dehydro-l-ascorbic Acid and their Related Compounds
Authors: Wasa Tamotsu , Takagi Masanosuke , Ono Sôzaburo 
Published: July 2006

Abstract
The polarographic behavior of dehydro-l-ascorbic acid (DAA), dehydroreductic acid (DRA), alloxan, mesoxalaldehyde (MOA) and 2,3-diketogulonic acid (DGA) in acid buffer solutions containing o-phenylenediamine(OPD), has been investigated.
DAA shows three diffusion controlled reduction waves, whose half-wave potentials(E1⁄2) at pH 3.60 are −0.26, −0.44 and −0.67 V. (vs. N. C. E.), respectively. The limiting currents of the three waves depend on the time after the addition of OPD into the electrolytic solution, the concentration of OPD. pH and the temperature. When the electrolytic solution contains both AA and DAA, the oxidation wave of l-ascorbic acid (AA) can be obtained independently of the three waves for DAA in one polarogram.
DGA shows two reduction waves whose E1⁄2 at pH 3.44 are −0.27 and −0.40 V., respectively. The E1⁄2 of the first wave is very close to that of the first wave for DAA and the second wave seems to be identical with the second wave for DAA, but the velocities of the condensation reactions of DGA with OPD are much slower than those of DAA with OPD.
Alloxan and DRA show single well defined reduction waves, whose E1⁄2 at pH 3.60 are −0.32 and −0.19 V., respectively. The oxidation wave of reductic acid (RA) can be obtained with the reduction wave for DRA in one polarogram, while the oxidation wave of dialuric acid decreases very fast when alloxan and OPD are added into the electrolytic solution even after the careful removal of the atmospheric oxygen.
MOA shows a somewhat complicated behavior. In acid pH, the waves are not well defined and are considerably smaller than those of the above substances of the same concentration.
Discussions are made on the structures of the condensation products corresponding to their reduction waves.
Since the linear relationship between the limiting current and the concentration has been obtained, for DAA (the 3rd wave), DRA and alloxan, these polarographic phenomena have been applied to the simultaneous determination of AA and DAA, and to that of RA and DRA and further to that of AA and RA. The method is also applicable to the determination of alloxan, but not to those of MOA (or TR) and DGA, none of which, however, seriously interfere with the determination of DAA (or AA) by means of this polarographic OPD method.
Simultaneous Polarographic Determination of a System of o-Nitroanisole, o-Chloronitrobenzene and o-Nitrophenol
Authors: Honda Kenichi , Kikuchi Shin-ichi 
Published: July 2006

Abstract
1) The solution of o-nitroanisole, o-chloronitrobenzene and o-nitrophenol is investigated polarographically with the intention of their simultaneous determination.
2) The most suitable supporting electrolyte solution for the above object is the mixture of 4 parts of 1 n sodium hydroxide and 1 part of methanol.
3) Although this solution is not buffered, the variation of concentration of one component does not exert appreciable influence upon the wave-heights and the relative positions of the waves of other two components.
4) o-Nitrophenol can be determined directly from the ordinary polarogram. The accuracy of determination is under ±10%.
5) The residual current compensation gives aid to the determination of o-nitroanisole and o-chloronitrobenzene. By passing the compensating current very excessively, their reduction waves become better defined. The accuracy of determination is +8∼−17% for o-nitroanisole and −24∼−9% for o-chloronitrobenzene.
6) The half-wave potentials of three compounds, 5×10−4 m/l. in 1 n sodium hydroxidemethanol (4:1) solution are as follows;
(Remark: Graphics omitted.)
These values would give some indications for the estimation of the separation of waves.
Secondary Electron Emission from Copper-Beryllium (4%) Surface by Bombardment of Various Positive Ions
Authors: Sugiura Toshio , Hayakawa Teruo 
Published: July 2006

Abstract
The secondary electron emission from the non-activated and activated surfaces of copperberyllium (4%) by the impacts of various noble gas and hydrocarbon ions was studied together with the determination of the surface structure by the electron diffraction analysis. The main results obtained are as follows.
(1) The considerably thick layer of beryllium oxide is formed in the neighborhood of the target surface activated by oxygen at the temperature range of 350 to 480°C.
(2) The oxide films of copper are formed on the target surface by electropolishing, but these oxides easily undergo reduction by the prolonged ion bombardments.
(3) The optimum temperature of activation for the electron yield seems to be about 420°C, and the electron yield for the activated target surface treated at 350 or 420°C is only slightly dependent upon the ion kinetic energy.
(4) No measurable decrease in the electron yield for the activated surface treated at 420°C was obtained by the prolonged bombardments of various positive ions for ten hours, while the electron yield for the non-activated surface decrease about 20 per cent by the prolonged bombardments of ions for five hours.
(5) Under the present experimental conditions, the mechanism of the electron ejection process seems to be considerably complicated and it is difficult to deduce any definite conclusion for the electron ejection process.
Mineral Content of Mixed Fertilizer
Authors: Ando Jumpei , Matsuno Seiichi 
Published: July 2006

Abstract
The mineral content of mixed fertilizer produced with calcium superphosphate, ammonium sulfate and potassium chloride and also the reactions during the production process were investigated by X-ray diffraction.
It was observed that remarkable reactions took place between monocalcium phosphate, calcium sulfate, ammonium sulfate and potassium chloride by the addition of water for granulation. At the beginning of drying of the wet granules these minerals almost disappeared to form ammonium chloride and crystalline solutions of ammonium and potassium syngenite and those of monoammonium and monopotassium phosphate.
The syngenite thus formed decomposed partly by further drying and again formed while the product was placed in a storage pile. It seems that the caking of the product which often occurs in a storage pile is caused mainly by the crystallization of syngenite which decreases the amount of free water in the product and makes other salts crystallize at the same time.

Published: July 2006

Abstract
Procedures have been developed for the spectrophotometric determination of trace amounts of beryllium, copper and iron(III) with sodium-2″,6″-dichloro-4′-hydroxy-3,3′-dimethylfuchsone-5,5′-dicarboxylate. Certain ions that interfere with the beryllium determination are removed by an oxine precipitation. Ions that interfere with the analysis of copper and iron(III) are removed with an anion exchange resin column.
Accuracy and precision are good. Beer’s law is obeyed up to about 0.3 p.p.m. of beryllium, about 4 p.p.m. of copper and about 3 p.p.m. of iron.
Dehydrogenation of Secondary Alcohols with Reduced Copper. IV. Catalytic Dehydrogenation of Isopropyl Alcohol (Part 2)
Authors: Kawamoto Kazuaki 
Published: July 2006

Abstract
The present work is to determine whether the yields of acetone and of the oily products (isobutyl methyl ketone and diisobutyl ketone) to be obtained from isopropyl alcohol by the catalytic action of reduced copper are affected by the precipitation temperature in the preparation of the catalysts, and to find a catalyst efficient for the production of oily products. Isopropyl alcohol was changed to acetone in 91∼95% yield with no side reaction, by being passed over various copper catalysts at 325°C. The maximum yield of the oily products was obtained with the catalyst prepared with sodium hydroxide as a precipitant and at 22°C as the precipitation temperature, and at the reaction temperature of 220°C, amounting to 39.28% based on isopropyl alcohol used.
