Authors: Kuo C. H. , Shih J. S. , Yeh Y. C. , Wu S. C. 
Published: June 2015

AbstractIsobutanol in phosphoric acid was detected by gas chromatography with a flame ionization detector. Samples with high content (>100 μg/ml) of isobutanol were diluted with a n‐pentanol aqueous solution and the diluted solutions were directly injected into the GC column for the determination of isobutanol. For lower content samples, isobutanol was preconcentrated by vacuum distillation or CCl4 extraction followed by activated alumina adsorption. In whole GC measurements, n‐pentanol was used as an internal standard.The flame ionization detector is capable of detecting quantities of isobutanol as small as 5×10−8g. With preconcentration, isobutanol at the concentration of 0.4 μg/ml or lower can be determined.
Spectrophotometric and Polarographic Studies on 9,10‐Anthradione‐2‐Sodium Sulfonate
Authors: El‐Maraghy Salah B. , Ebied M. F. E. , El‐Wafa S. 
Published: June 2015

AbstractThe effect of solvent structure on the rates of redox reactions in alcohol+water mixture was discussed by some authors. The rate of photoreduction of 9,10‐anthraquinone‐2‐sulfonate was decreased by addition of H2SO4 but was unchanged by increase of ionic strengh with (NH4)2SO4. The magnitude of the decrease in presence of acid was greater with ethanol or isopropanol than with N‐ethylacetamide as substrate. The formation of semiquinone and carbonate radical anions was observed(4) during the direct photoreaction. The electron transfer from the carbonate anion to sulfoanthraquinone in the first excited triplet state was the controlling step of this process. Therefore, anthraquinone β‐sodium sulfonate is efficient sensitizers of the photooxidation of organic substrates in aqueous media.
An Investigation of the Effect of Air‐Oxidation on Coal Liquefaction
Authors: Chang Ching‐Yuan , Guin James A. , Tarrer Arthur R. 
Published: June 2015

AbstractExperiments are performed to investigate the effects of oxidation upon coal liquefaction in a combined pre‐oxidation‐liquefaction process. It is found that the air‐oxidation of coal preceding liquefaction is generally detrimental to liquefaction yields for both cases with or without presence of hydrogen gas in the dissolution step, and could be highly harmful to the processes which rely solely upon hydrogen donor solvents such as 1,2,3,4‐tetrahydronaphthalene. The analyses of oxidized and unoxidized coals show a significant decrease in hydrogen but increase in oxygen contents of the coal with oxidation. These factors together with the possible formation of oxygen‐coal bonds and the increase in —OH and/or —COOH groups in the oxidized coal are thought to account for the decreasing conversion of oxidized coal when it is subjected to liquefaction.

Chemical Phosphorylation of Nucleosomes and Histone H4
Authors: Lin Yuan‐Chuan , Smith Roberts A. 
Published: June 2015

AbstractUsing N,N′‐Dicyclohexylcarbodiimide (DCC) as a condensing agent, 32P‐cyanoethylphosphate and NH3 were combined to yield 32P‐cyanoethylphosphoramidate. Treatment with NaOH resulted in a β‐elimination step to yield 32P‐phosphoramidate and acrylonitrile. The phosphoramidate was purified via DEAE‐cellulose chromatography. At pH 7.4 the histidine residues of histone H4 were chemically phosphorylated using 32P‐phosphoramidate as the phosphoryl donor. The nucleophilic nitrogen of the imidazole ring is attracted to the phosphorus of phosphoramidate resulting in the displacement of NH3 and formation of the protein phosphoryl‐nitrogen linkages.Chromatin monomers (nucleosomes) were prepared by a mild digestion of chromatin with micrococcal nuclease. This report also presents the chemical phosphorylation of these nucleosomes by 32P‐phosphoramidate.

Authors: Jwo Jing‐Jer , Chen Yih‐Hsiung 
Published: June 2015

AbstractThe presence of ceric and bromide ions catalyzes the isomerization of maleic acid (MA) to fumaric acid (FA) in aqueous sulfuric acid. A kinetic study of this bromine‐catalyzed reaction was carried out. The reaction between ceric ion and maleic acid is first order with respect to Ce(IV). For [Ce(IV)]0=5.0×10−4 M, [H2SO4]0=1.2 M, μ=2.0 M (adjusted by NaClO4), and [MA]0=(0.5–1.0)M, the observed pseudo‐first‐order rate constant (k03) at 25° is k03=7.622×10−5 [MA]0/(1+0.205[MA]0). The reaction between ceric and bromide ions is first order with respect to Ce(IV). For [Ce(IV)]0=5.0×10−4 M, [H2SO4]0=1.2 M, μ=2.0 M, and [Br−]0=(0.025–0.150)M, the pseudo‐first‐order rate constant (k02) at 25° is k02= (4.313±0.095)x10−2[Br−]2+(2.060±0.119)x10−3[Br−]. The reaction of Ce(IV) with maleic acid and bromide ion is also first order with respect to Ce(IV). For [Ce(IV)]0=5.0×10−4 M, [MA]0=0.75 M, [H2SO4]0=1.2 M, μ=2.0 M, and [Br−]0= (0.025–0.150)M, the pseudo‐first‐order rate constant (k03) at 25° is k03= (5.286±0.045)x10−2[Br−]2+(3.568±0.056)x10−3[Br−]. For [Ce(IV)]0=5.0 × 10−4 M, [Br−]0=0.050 M, [H2SO4]0=1.2 M, μ=2.0 M, and [MA]0=(0.15–1.0)M at 25°, k03=(2.108×10−4+2.127×10−4[MA]0)/(1+0.205[MA]0). A mechanism is proposed to rationalize the results. The effect of temperature on the reaction rate was also studied. The energy barrier of Ce(IV)—Br− reaction is much less than that of Ce(IV)—MA reaction. Maleic and fumaric acids have very different mass spectra. The mass spectrum of fumaric acid exhibits a strong metastable peak at m/e 66.5.

Authors: Mathur K. C. , Saxena M. K. 
Published: June 2015

AbstractThe anhydride of cis‐4‐cyclohexene‐1,2‐dicarboxylic acid was condensed with phenanthrene, acenaphthene and fluorene in the presence of anhydrous aluminium chloride to give the corresponding 2‐(aroyl) cyclohex‐4‐ene‐1‐carboxylic acids. These keto acids when subjected to Wolf‐Kishner reduction yielded the corresponding 2‐(aryl) cyclohex‐4‐ene‐1‐carboxylic acids, which were then converted into their respective acid chlorides by refluxing with thionyl chloride in benzene. The acid chlorides in turn were cyclised by anhydrous aluminium chloride in carbon disulphide to give the corresponding cyclic ketones. These cyclic ketones were then reduced by Wolf‐Kishner method to furnish the desired hydrocarbons, 2,3‐cyclohex‐2′‐ene‐5,6‐substituted cyclohexanes.

Theoretical Infrared Radiative Lifetimes for CO a3∏
Authors: Lie G.C. 
Published: June 2015

AbstractINDO self‐consistent‐field method was employed to calculate the potential energy and dipole moment functions for the excited a3∏ state of CO. Vibrationally averaged dipole moments and infrared radiative lifetimes were then obtained from the dipole moment function and vibrational wave functions generated by solving numerically the Schrödinger equation for nuclear motions. The calculated dipole moment is 1.468 (expt'I 1.375 D) for ν=0, and decreases with increasing ν, as found experimentally. Calculated infrared radiative lifetimes, with experimental results in parentheses, are 13.5 (17.3, 19.0±5.9), 7.3 (7.8, 13.1±2.9), and 5.0 (4.7, 5.6±1.0) msec, respectively, for ν=1, 2, and 3. The polarity of calculated dipole moment is C+O−, differing from that for the ground X1∑+ state. The origin of this difference is found to be due to the delocalization of the 5a orbital in the a3∏ state.

AbstractPrevious publication showed that the stereochemistry of lithium aluminum hydride reduction of cyclic ketones can be evaluated by the use of an empirical equation, . This paper reports further test of this relationship in the new system of 2,2‐dimethyl‐4‐t‐butyl‐cyclohexanone.Lithium aluminum hydride reduction of this ketone yields 95.6% trans‐alcohol (lit., 95.9%) corresponding to D̊(D̊G*)H of 1.67 Kcal/mol. With methyllithium, the ketone formed 77.5% of trans‐alcohol (D̊(D̊G*)D̊fs = 0.67 Kcal/mol). These data give a calculated D̊G* = 0.74 Kcal/mol which agrees well with the literature value of 0.87 or 0.28 Kcal/mol.Structural assignments of 2,2‐dimethyl‐4‐t‐butylyclohexanone, 1,2,2‐trimethyl‐cis‐ and trans‐4‐t‐butylcyclohexanols by pmr spectroscopic method are also given.
