ON THE PRESENCE OF INERT GASES IN SOME MINERAL SPRING GASES IN JAPAN
Authors: Suganuma I , Kitaoka K 
Published: July 2006

Abstract
Researches of inert gases in some mineral spring gases in Japan have been carried out with the conclusion that the primordial inert gases were contained in the ancient air which was enclosed in the internal parts of the earth, and in the long course of time the oxygen and nitrogen were gradually lost owing to their chemical activity leaving behind inert gases such as helium, neon, and argon. When the spring gases are produced largely underground and gush out of the earth they are accompanied generally by the primordial gases, that is to say, they come out upwards together with the inert gases.

(2) Absorption of light by the various organic vapours, hydrogen chloride, and chlorine has been studied by this apparatus, and it has been found that all except chlorine are transparent to 3650 and 4350Å from the mercury lamp as a light source.
THE HIGHLY UNSATURATED ACIDS IN SARDINE OIL. VIII THE CONSTITUTION OF CLUPANODONIC ACID C22H34O2
Authors: Toyama Yoshiyuki , Tsuchiya Tomotaro 
Published: July 2006

Abstract
1. Amyl clupanodonate was subjected to ozonolysis. Among the products of ozonolysis were found propyl aldehyde, acetaldehyde, carbon dioxide, succinic acid, amyl hydrogen succinate and also lower acids which were deemed to consist of propionic and acetic acids. Of these compounds, acetaldehyde, acetic acid and carbon dioxide are attributable to the secondary decomposition of the products of ozonolysis primarily derived from the group =CH· CH2·CH=. Accordingly clupanodonic acid was shown to contain the following groups: CH3·CH2·CH=, =CH·(CH2)2·COOH, =CH·CH2·CH= and =CH·(CH2)2·CH=, of which clupanodonic acid contains three of the last named group.
2. The dibromo-derivative of clupanodonic acid was separated as the chief constituent of the product which was obtained by adding 1 mol bromine to 1 mol clupanodonic acid. Similarly tetrabromo- and hexa-bromo-derivatives of clupanodonic acid were separated, respectively, as the chief constituents of the product obtained by adding 2 mols and 3 mols bromine, respectively, to 1 mol clupanodonic acid. It is seen from the following results obtained by the ozonolysis of these bromo-derivatives that, in these partial brominations, bromine adds selectively first to the ethylenic linking which is more distant from the carboxyl group. Though this selectivity is not a complete one, any of the above-mentioned bromoderivatives contains as its chief constituent the product formed in accordance to this selectivity.
3. Ozonolysis of dibromo-derivative of clupanodonic acid thus obtained gave a bromo-compound which on debromination and subsequent hydrogenation yielded, as an acidic product, heptoic acid. This fact, coupled with the results obtained by the ozonolysis of amyl clupanodonate, indicated that clupanodonic acid had the group CH3·CH2·CH=CH·(CH2)2·CH=.
4. Ozonolysis of tetrabromo-derivative of clupanodonic acid gave a bromo-compound which on debromination and subsequent hydrogenation yielded capric acid, and consequently clupanodonic acid was shown to contain the group CH3·CH2·CH=CH·(CH2)2·CH=CH·CH2·CH=.
5. Ozonolysis of hexabromo-derivative of clupanodonic acid gave a bromo-compound which on debromination and subsequent hydrogenation yielded myristic acid, and consequently clupanodonic acid was shown to contain the group CH3·CH2·CH=CH·(CH2)2·CH=CH·CH2·CH=CH·(CH2)2·CH=.
6. From the foregoing results, the constitution of clupanodonic acid has been established as Δ4:5,8:9,12:13,15:16,19:20-docosapentenoic acid which is expressed by the following formula: CH_3·CH_2·CH=CH·(CH_2)_2·CH=CH·CH_2·CH=CH·(CH_2)_2·CH=CH·(CH_2)_2·CH=CH·(CH_2)_2·COOH.

Authors: Toyama Yoshiyuki , Akiyama Goroku 
Published: July 2006

Abstract
Hexadecenol has been separated, in a very small yield, from the unsaponifiable matter of sperm blubber oil, and its constitution has been established as CH3·(CH2)5·CH=CH·(CH2)7·CH2OH. Hence, hexadecenol in sperm blubber oil is proved to be identical with zoomaryl alcohol (Δ9:10-hexadecenol) previously found in sperm head oil.

Authors: Toyama Yoshiyuki , Tsuchiya Tomotaro 
Published: July 2006

Abstract
A decenoic acid has been separated from sperm head oil. Its methyl ester was oxidised with potassium permanganate in acetone, and after the saponification of the acid ester contained in the oxidation products, azelaic acid was identified. The presence of formic acid in the oxidation products was also indicated. Accordingly the decenoic acid in sperm head oil is proved to be Δ9:10-decenoic acid, having the formula CH2=CH·(CH2)7·COOH.

ON THE VISCOSITY OF THE CRITICAL MIXTURE OF TERNARY SYSTEM BENZENE-ALCOHOL-WATER
Authors: Kimura Osamu 
Published: July 2006

Abstract
(1) The viscosity of the three component system benzene-ethanol-water was measured in the neighbourhood of critical point.
(2) To the homogeneous region Andrade’s formula is strictly applicable but not to the colloidal region. This deviation is caused by the existence of colloid particles.
(3) The concentration of colloid particles was calculated by using Hatschek’s formula, and it was of the order of 0.0001 near the critical point.
OPTICAL ROTATORY DISPERSION OF SOME BRIDGED DERIVATIVES OF ALKYLTARTRATES
Authors: Tsuzuki Yojiro 
Published: July 2006

Abstract
(1) Rotatory dispersions in the region from 6708 Å to 4358 Å of diethyl and dimethyl isopropylidene-tartrates, diethyl and dimethyl ethylidenetartrates and diethyl methylene-tartrate, bridged derivatives of alkyltartrates, in which both the hydroxyls are linked with the rest of the carbonyl compounds have been measured, all with no solvent, and shown to be expressed by one term of Drude’s equation.
(2) It is pointed out that the absorption bands of the condensation products from ketone are located at about 1750 Å, whereas those of the compounds derived from aldehydes at about 2100 Å, and the relation between these values and the chemical constitution is discussed.
(3) Considering the fact that the dispersion ratio α4358⁄α5461 and the characteristic wave length λ0 range from 1.674 to 1.748 and from 1735 Å to 2141 Å respectively, the rotatory dispersion of these compounds is concluded to be very probably simple.
THE ELECTROLYTIC FORMATION OF PERSULPHATE. PART II
Authors: Matsuda Ryoichi , Nishimori Teruichi 
Published: July 2006

Abstract
(1) Experiment 1. 7 N sulphate solutions are electrolysed with an unignited Pt-anode, diaphragm being disused. The highest C.E.(2) is obtained in the case of 7 N ammonium sulphate containing no free H2SO4, which fact the present authors’ view is able to account for, but not Elbs’.
(2) Experiment 2. The same kinds of solutions are electrolysed without diaphragm as in the previous experiment and the favourable effect of using the ignited Pt-anode is clearly observed in the case of solutions containing ammonium sulphate. The C.E. in the present case, in general, does not seem inferior to that of electrolysis with diaphragm. 7 N H2SO4 solution containing no ammonium sulphate, however, has a very poor C.E. which is attributed to the vigorous cathodic reduction, in this solution, of the anodic products.
(3) Experiment 3. Four 15 N sulphate solutions are electrolysed. Caro’s acid, being formed in an appreciable amount, is proved to be helpful in explaining the mechanism of the anodic reactions from the view-point of OH′-concentration. It is suggested in this case that the viscosity of the solution has more or less effect on the C.E.
(4) Experiment 4. Three 20 N sulphate solutions are electrolysed, in which the total C.E.’s are smaller and Caro’s acid ones greater than the corresponding values in the 15 N solutions. As in the previous cases, the more concentrated the solution with respect to ammonium sulphate, the greater the total C.E. The behaviour of Caro’s acid and the viscosity of the solution are discussed in connexion with the C.E.
(5) Experiment 5. Change of the C.E. with time is traced to 15 hours, when 15 N H2SO4 solution is electrolysed at a constant C.D.(2) And it is found that electrolysis without diaphragm is, again, not inferior, but rather superior, to that with it with regard to C.E.
(6) The present authors’ view about the mechanism of electrolytic formation of persulphate comes into line with that proposed by one of them (R.M.)(4) for Kolbe’s reaction. Thus it is shown that electrolytic oxidation of both inorganic and organic compounds is explicable by one and the same theory.
SPECTROGRAPHIC METHODS OF STUDYING UNSTABLE COMPOUNDS. II. THE AQUOTIZATION OF TRANSDICHLORO-TETRAMMINE COBALTIC CHLORIDE IN AQUEOUS SOLUTIONS
Authors: Tsuchida Ryutaro 
Published: July 2006

Abstract
(1) A new complex compound [Co(NH3)4Cl H2O(6)(1)]Cl2 was found by the spectrographic analysis.
(2) Trans-dichloro-tetrammine cobaltic chloride in aqueous solutions changes in the following scheme:
(Remark: Graphics omitted.)
(3) The velocity constants of the first two reactions were found to be 1.39×10−3 and 9.05×10−4 respectively.
(4) The absorption curves were found for the unstable complex salts [Co(NH3)4Cl2(6)(1)]Cl and [Co(NH3)4Cl H2O(6)(1)]C12, both of which can never exist in acqueous solutions without contamination of related compounds.
(5) The praseo-salt shows a third absorption band of the same type as that of [Co(NH3)4(NO2)2(6)(1)]Cl.
(6) The third absorption band is supposed to be one of the general characteristics of those complex salt which have in the co-ordination at least one pair of ions in trans-positions to each other.
(7) Substitution of Cl in [Co(NH3)4Cl2(6)(1)]Cl or [Co(NH3)4Cl H2O(2)(1)]C12 by H2O, has hypsoehromic effect.
On the Relation between the Configuration of Metallic Complex Salts and their Absorption Spectra
Authors: Sueda Hideo 
Published: July 2006

Abstract
(1) From the comparison of absorption curves given by nitroammine-cobaltic complex salts near 360 mμ of wave length, the following assumption was deduced: the absorption band presented by complex salt solutions can be resolved into the elements (characteristic absorption) which are due to the pairs of co-ordinated groups situated in transposition in a complex radical, and these elements show an additive property in the same complex ion.
(2) By taking into account of the above-mentioned point of view, K[Co(NH3)2(NO2)4] (Erdemann’s salt) should have a trans-configuration.
(3) This assumption may also be applied to the absorptions given by aquo-chloro-ammine salts of cobalt and chromium, in visible and ultraviolet regions.

Abstract
(1) Dimethylmalonic acid and formic acid were obtained by the oxidation of shonanic acid.
(2) A hydrocarbon C10H20 was obtained by the reduction of shonanic and tetrahydroshonanic acid with hydroiodic acid.
(3) A hydrocarbon C9Hi16 (Remark: Graphics omitted.) was obtained by the dry distillation of shonanic acid with soda-lime.
(4) The attempt to determine the ring structure of shonanic acid by comparing the properties of these hydrocarbons with those of known hydrocarbons gave no reliable results.
(5) The formation of o-dinitrobenzene from shonanic acid by treating it with dilute nitric acid may be taken as an evidence for the presence of six-membered ring system in its molecule.

Authors: Sueda Hideo 
Published: July 2006

Abstract
(1) The absorption spectra of six solutions of chromic chloride and sulphate hydrates were quantitatively measured in the ultra-violet region.
(2) Violet chromic sulphate and chrome alum should respectively have the formula [Cr(H2O)6]2(SO4)3 and K[Cr(H2O)6] (SO4)2.
(3) Chloro-aquo chromic salts were transformed into the hydroxopentaquo chromic salts in the solutions where the pH-values were higher than 4.0.
(4) The substitution of a chlorine atom for a molecule of water in these salts caused the absorption band to shift in the direction of the increasing wave length and absorption capacity.
(5) Following his method, the author has made a comparison of calculated and observed values of the absorption of green chromic chloride.
Experimental Studies on the Electrochemical Polarisation Produced in the Cylindrical Mass of Litharge. I
Authors: Tiku Takewo 
Published: July 2006

Abstract
Litharge powder was mixed with distilled water and turned to pasted form. This was stuffed in glass tubes of moderate length at their middle portions, and direct electric current was passed through the mass. Positive and negative patterns due to electrolytic polarisation was produced in the mass facing each other at definite positions in the axial direction of the cylindrical mass, the position of the negative being near the positive end of the mass. The ratios of the distance P of the positive position from the negative end to the length l of the mass were found to be independent of the length in the average.
The value of P⁄l is affected by the modification of litharge, but not by the diameter, the length of the mass and the terminal voltage.
Dipole Moments of Benzil and Stilbene Dichloride
Authors: Higasi Ken-iti 
Published: July 2006

Abstract
(1) The dipole moment of benzil was studied in three solvents and its temperature dependence was examined.
(2) The carbon-carbon bond of benzil is not a pure single bond and is probably a hybrid of single and double bonds. This is the result expected from Thiele’s old idea of conjugated system and also from the quantum mechanical resonance.
(3) The dipole moment of α-stilbene dichloride was also studied in benzene and carbon tetrachloride solution. The result was compared with that of ethylene dichloride.
Quantum Mechanical Resonance and Internal Rotation
Authors: Mizushima San-ichiro , Kubo Masaji 
Published: July 2006

Abstract
The effect of single bond—double bond resonance upon the internal rotation was discussed for carboxylic and their derivatives. In acids and ester the strong carboxylic resonance imparts the double bond character to the C–O bond the actual “mesomeric” molecule to such an extent that practically the complete inhibition of the internal motion is realized at all ordinary temperatures, while the replacement of hydrogen of H–COOR by chlorine or methoxyl group greatly reduces this double bond character, so that the internal oscillatory rotation of finite amplitude can take place about the C–O bond as axis.

(1) Solid sample electrodes were prepared from carbon, “sirupus simplex” and varying amounts of lithium chloride and the amount of lithium chloride was spectrographically determined with a sensitivity of 3×10−5% with respect to the line at λ=6707.9 Å, and with that of 1×10−4% with respect to the line at λ=6103.6 Å.
(2) The method of comparison was found to be applicable for the determination of lithium chloride throughout the range of 0.001–0.050%.

Authors: Tsuchida Ryutaro , Tsumaki Tokuichi 
Published: July 2006

Abstract
(1) Absorption spectra of benzaldehyde-ethylenediimine, o-methoxybenzaldehyde-ethylenediimine, salicylaldehyde-ethylenediimine and o-hydroxyacetophenone-ethylenediimine have been measured, and the structures of the spectra have been qualitatively explained by the theories of absorption spectra of coordination compounds.
(2) The longest-waved band of salicylaldehyde-ethylenediimine as well as of o-hydroxyacetophenone-ethylenediimine has been explained as due to intramolecular formation of a hydrogen bridge between the hydroxyl group and the nitrogen atom. In other words an absorption band of a hydrogen bond has been found in the near ultra-violet region.
(3) The absorption spectrum of salicylaldehyde-ethylenediimine-cobalt has been explained and the steric configuration of the inner complex has thereby been corroborated.
