Authors: Yeh Si Jung , Chen Ping Yao , Hsu San Te 
Published: June 2015

AbstractTrace amount of mercury in human hair has been determined by destructive neutron activation analysis.It was found that the contents of mercury in the hair of normal people in Taiwan area is the order of 6 ppm. It is of interest to point out that very little fluctuation is observed in the contents of mercury in human hair regardless of sex and age of the normal people under investigation.On the other hand for those people who are working in the caustic soda manufacturing plant in which mercury is used as cathode in the electrolysis process of saline water, the mercury contents in their hair are definitely much higher (ca. 30 times) than the average values of normal people.

Authors: Liu Lilian Kao 
Published: June 2015

AbstractThe mass spectra of saturated sulfonate esters1,2) have been reported recently. No study has been made on the vinylic methanesulfonates. In order to understand their breakdown patterns, several chloro‐ and fluoro‐containing vinyl methanesulfonates have been made3) and their mass spectra studied. The chlorine compounds are chosen because the natural abundance of isotope 35Cl and 37Cl can serve as a internal tag. The vinyl methanesulfonates containing electronegative fluorine are used as a comparison to the chloro‐compounds because of their similar electronegativities.

AbstractTreatment of aliphatic 1,2‐, 1,3‐ or aromatic o‐diamine with carbon disulfide provided the corresponding cyclic pseudothioureas (IIb‐j). Heating thiourea (IIa) or these compounds with dimethyl or diethyl acetylenedicarboxylate (IIIa, b) in ethanol resulted a nucleophilic addition of the sulfhydryl group to the C≡C bond accompanied with a ring‐closure condensation. Thus a series of alkoxycarbo‐methylidene derivatives of 2‐imino‐4‐thiazolidinone (IVa), imidazolo‐, benzimidazo‐and tetrahydropyrimido (2, 1‐b)‐3‐thiazolidinones (IVb‐k) was produced. An orientating experiment of saponifying the ester function of these compounds has also been carried out.

Published: June 2015

AbstractSorbohydroxamic acid forms with uranium an orange red, water soluble complex. The mole ratio of uranyl ion to compound is 1 to 1 under the investigated conditions. The formation constant of this chelate was also determined by the Likussar—Boltz method at a constant ionic strength of 0.1 M at 30°C as 2.10×102. The recommended procedure obeys Beer's law between 3.98ppm and 166.6ppm of uranyl ion at pH 3.8±0.1. Tolerances to cerium (IV) and thorium have been investigated. The procedure for the determination of uranium are made more specific by applying preliminary extraction of uranium by ether.

AbstractCerium(III) chelate of 7‐iodo‐8‐hydroxyquinoline‐5‐sulphonic acid(ferron) has been studied spectrophotometrically in aqueous solution at 25°C and at an ionic strength of 0.1M. The formation of this chelate was pH dependent, and the optimum pH range was between 5.5 to 6.0. Its mole ratio of ligand to cerium(III) ion was found to be 2 to 1 stoichiometry and the formation constant, logK, was determined as 10.15. Enthalpy and entropy changes characterizing the formation of the chelate have been calculated as follows: ΔG° =‐13.85kcal mole‐1, ΔH°= −5.03 kcal mole‐1, ΔS°=29.56 eu mole‐1. By using the wavelength of 370 nm, determination of trace amount of cerium(III) ion with the sensitivity of 0.056 was possible.

Steady State Approximation on Constant‐Stepsized Computer Simulation
Authors: Lee Wei‐Min , Yeh Chuin‐Tih 
Published: June 2015

AbstractConstant‐stepsized computer simulation of chemical reactions gives unreasonable results when the accepted stepsize exceeds a limit. The maximum permitted stepsize is found as the lifetime of the most reactive intermediate in the mechanism from mathematical derivations on simple reaction models. Steady state approximation on this reactive intermediate may relieve this limitation and save computer's computation time. This approximation method has been satisfactorily applied to the simulation of the thermal decomposition of methane.

AbstractThe partition of Fe(II) between hydrochloric acid solution and solvent of di‐(2‐ethylhexyl)‐phosphoric acid (HDEHP) in kerosene has been studied at varying concentrations of hydrochloric acid, solvent and Fe(II) ion. A stoichiometric extraction equation was derived as:Fe2+(a)+2(HX)2(0)=FeH2X4(0)+2H+(a)where the subscripts a and o refer, respectively, to aqueous and organic phases. Corresponding to the stoichiometries, value of Ks which equaled was obtained from the plot of D[H+]2 vs. F2 where D is the observed distribution ratio, F the concentration of HDEHP in organic phase. The kinetic studies of the extraction of Fe(II) species from hydrochloric acid into HDEHP under nitrogen atmosphere was carried out and the forward and back reaction constant was calculated. Also the oxidizing effect of air on the HDEHP‐Fe(II) complex in organic phase was studied.

Superheating Limit of Boiling n‐Hexane Spinodal Decomposition Versus Nucleation Process
Authors: Yang Chan‐Lon , Mou Chung Yuan 
Published: June 2015

AbstractTwo predicative theories for superheating limits of a boiling liquid are considered in this work. In the nucleation picture, classical homogeneous nucleation theory is used to calculate superheating temperature at various pressures. In spinodal decomposition picture, stability limits are taken as the superheating temperature. A perturbed‐hard chain equation of state was developed and used for the purpose of calculating mechanical stability limit. Calculations are done for the case of normal hexane at different pressures and compared with experimental results. Classical nucleation theory gives good prediction at negative and smaller pressures. While near critical pressure, spinodal picture seems to be more accurate.

Authors: Lin Ivan J. B. 
Published: June 2015

AbstractSome halo or mercaptide bridged palladium (II) dimers, [Pd(S2CNR2)X]3 (R=ibutyl, X=Cl, Br, I, S‐ethyl and S‐t‐butyl) were studied by variable temperature 1H nmr spectroscopy. Line shape changes of the chloro and bromo bridged dimers were interpretated by the solvolytic breaking of the Pd‐X bond, while mercaptide bridged complexes were explained in terms of slow N‐C single bond rotation. The results consist with the strengthness of the class b metal ion with various soft donor ligands.

Isomerization of Maleic Acid to Fumaric Acid Catalyzed by Bromate Ion and Bromine
Authors: Chen Yih‐Hsiung , Jwo Jing‐Jer 
Published: June 2015

AbstractIn the presence of a relatively small amount of bromate, maleic acid in aqueous sulfuric acid isomerizes catalytically to fumaric acid in the dark at room temperature. The concomitant presence of a suitable amount of bromine in CCI, phase raises the rate and yield significantly. The yield and rate of isomerization depend on the relative amounts of maleic acid, bromate, bromine, and sulfuric acid. For a favorable condition, nearly 90% yield can be obtained. Raising the temperature accelerates the production of fumaric acid while decreases the final yield. The isomerization reaction competes favorably with the redox reaction at room temperature while the latter dominates at high temperature. For the heterogeneous case, the agitation of the reaction mixture delays the isomerization. The presence of cumene or benzene inhibits the isomerization. Hypobromous acid is proposed to play a major role in catalyzing the isomerization. A mechanism is proposed to rationalize the experimental results.
Synthesis of 6,9‐Dipropyl‐1,4‐Dioxaspiro[4.5] Deca‐6,8‐Diene‐2,10‐Dione and its Diels‐Alder Reactions with Substituted Acetylenes
Authors: Liao C. C. , Lin H. S. 
Published: June 2015

AbstractThe title compound, a masked 3,6‐di‐n‐propyl‐o‐benzoquinone, was synthesized from 3,6‐di‐n‐propylcatechol in 82% yield. Its Diels‐Alder reactions with methyl propiolate, phenylacetylene, 1‐octyne, dimethyl acetylenedicarboxylate, diphenylacetylene and 3‐hexyne were studied. The yields of the adducts were excellent except for the last two cases in which the unimolecular decomposition of the title compound to generate 3,6‐di‐n‐propylcatechol methylene ether predominates. The regiochemistry of the adducts derived from monosubstituted acetylenes were determined by the correlation of 13C chemical shifts of the adducts and the corresponding bicyclo[2.2.2]octa‐5,7‐diene‐2,3‐diones obtained from the hydrolysis of the spirolactone ring of the Diels‐Alder adducts. Photolysis of these α‐diketones gave the corresponding aromatic compounds in high yields. These synthetic sequences provide an effective entry to bicyclo[2.2.2]octa‐5,7‐diene‐2,3‐diones and polysubstituted benzene derivatives.
Isomerization of Maleic Acid to Fumaric Acid Catalyzed by Cerium(IV) and N‐Bromo Compounds
Authors: Jwo Jing‐Jer , Chen Yih‐Hsiung , Chang Eng‐Fen 
Published: June 2015

AbstractMaleic acid (MA) in aqueous sulfuric acid undergoes catalytic isomerization in the presence of small amounts of Cerium(IV) ion and N‐bromosuccinimide (NBS) or N‐bromoacetamide (NBA). The rate of isomerization is very fast even at room temperature and the yield is quite acceptable. The rate of isomerization depends on the relative amounts of MA, Ce(IV), NBS, NBA, and H2SO4. However, maleic acid has greater effect on the final yield. Sulfuric acid exhibits more chemical effect than physical effects. The competitive redox reactions of Ce(IV), NBS, and NBA with MA limit the yield of isomerization to about 85%. In the vicinity of room temperature, a raise of five degrees in temperature nearly doubles the rate of isomerization. Acrylamide shows inhibitive effect on the isomerization. The rate of hydrolysis of NBS or NBA in aqueous acidic solution depends on the concentrations of hydrogen ion, and NBS or NBA itself. The rate of hydrolysis of NBA is much faster than that of NBS. Mechanism involving bromine atom as catalyst is proposed to explain experimental results.

AbstractThe polarography of lead ion in dimethyl sulfoxide (DMSO) was investigated in the DMSO concentration range 0–80 vol.%. The complex species identified were Pb2(DMSO)4+3, Pb(DMSO)2+3 and Pb(DMSO)2+6 in [DMSO]<10 vol.%, 10< [DMSO]<43 vol.% and [DMSO]>43 vol.%, respectively. In the presence of pamoic acid, the reduction of lead ion in DMSO was two‐electron reversible diffusion‐controlled at pH≤6.0, but it became irreversible at pH>6.0. The complex species identified was Pb(Dm)2(Pm)3(OH)6− at pH>6.0. The rate constants of electro‐reduction and electro‐oxidation, activation energies were determined. The hydrolysis constants of lead ion in dimethyl sulfoxide concentration 40–70 vol.% at pH 4.5–6.0 were found to be of the order of 10−6. The stability constants of the Pb(DMSO)2+3 and Pb(DMSO)2+0 were also determined to be of the orders of 101 and 105, respectively.

Published: June 2015

AbstractThe kinetics is studied for the phase transfer catalytic preparation of benzyl benzoate from sodium benzoate and benzyl chloride with tetrabutylaramonium iodide as catalyst in a well stirred batch reactor. Benzyl chloride is dissolved in toluene as the organic phase and sodium benzoate is dissolved in water as the aqueous phase. The kinetics of the overall reaction is described by a first‐order model based on the concentration of benzyl chloride in the organic phase at the later time of the batch reaction. The rate constant increases with an increase of the catalyst concentration while decreases slightly with an increase of the concentration of sodium benzoate under the experimental condition.

Analysis of Non‐Exponential Multi‐Component Emission of Aryl Ketones: The Cases for the Phosphorescence Spectra of Beta‐Naphthil and Benzophenone
Authors: Chow Tahsin J. , Marshall Wilson R. 
Published: June 2015

AbstractThe dual emission spectra of β‐naphthil in two different glasses at 77° K have been resolved to their individual components by a computerized kinetic phosphorescence spectrometry system. Both the time‐resolved spectrum which reveals the kinetic behavior of the excited states and the wavelength‐resolved spectrum which tells the nature of the emitting species are obtained. Several possible emission mechanisms are discussed based on the informations gathered through the resolution processes. Triplet‐triplet annihilation is shown to exist in solutions of benzophenone as well as in solutions of β‐naphthil. As concluded from the results of time‐resolved study, such kind of interaction is responsible for the non‐exponential distorsion of the decays. And according to the wavelength‐resolved studies, transoid and cisoid conformational isomers seem to accout for the sources of the dual emission of β‐naphthil.
