This relationship proves that the influence of solvents (decane, benzene, acetic acid, p-dichlorobenzene) on the rate constant is due to the nonspecific solvation of the reactants and the transition state. The values of the dipole moments of the TS calculated from experimenntal data within the scope of Equation (18.2) have the following values [87] ...

Figure 8.9 The pH dependence of the /z-octanol-water distribution ratio of pentachlorophenol (PCP, pKj = 4.75), 4-chloro-a-(4-chlo-rophenyl) benzene acetic acid (DDA, pKb = 3.66), 2-methyl-4,6-dinitrophenol (DNOC, pKia = 4.46), and 2,4,5-trichlorophenoxy acetic acid (2,4,5-T, pKia = 2.83). (from Jafvert et al., 1990).

A stock solution containing approximately 40 /xg/ml of ochratoxin A in benzene acetic acid (99 1) is prepared. The concentration as described for aflatoxins is determined by measuring the optical density at 333 nm (peak absorption wavelength for this toxin) and applying the following formula ... 

Table 4.5). The first was the three-dimensional procedure of Hartley (ref. 332) which employs the following three solvents 1) 1.5% (v/v) formic acid 2) benzene-acetic acid (9 1, v/v) 3) ethyl acetate-methanol-acetic acid (20 1 1, by vol.). The second method was the one-dimensional procedure of Morse and Horecker (ref. 333) and employed a modified solvent system containing benzene-pyridine-acetic acid (80 20 2) with 25 pi 2-mercaptoethanol added per 50 ml of solvent.

Acetoxylation of thiochroman-4-one can be accomplished in excellent yield using Mn(OAc)3 in a mixed benzene-acetic acid solvent (Equation 54) <2004T3427>. 

When the reaction is carried out with 1-acylisatins, ring opened products are formed using benzene, acetic acid or ethanol as the solvent. However, it has been reported that with... 

Progesterone was synthesized from ergosterol through many steps including the oxidation of an enamine intermediate, which was effected in a sodium dichromate-benzene-acetic acid system63,64 (Scheme 46). The same system was also used for other steroid enamines65. Yields were usually high (>75%). 

The reaction of l-phenyl-6,7-diethox -l,2,3,4-tetrahydroiso-quinoline with benzoyl C3 anide in benzene-acetic acid gave rise to 54 which on basic hydrol3 sis yielded l-phenyl-6,7-diethoxy-l,2,3,4-tetrahydroisoquinoline-1 -carboxamide. ...

This compound is obtained by reducing 4-nitro-2-methyldiphenylamine-6 -arsinie acid, or by reducing 2-nitro-4 -methylphenarsazinic acid with sulphur dioxide. From o-didilorobenzene it separates in deep yellow needles, melting with decomposition at 303° to 305° C., insoluble in benzene, acetic acid, alcohol and ether, but slightly soluble in acetone.

By using the same methods as for acetone Sand and Geiissler isolated a body resembling that from the loAver ketone. When this compound is treated Avith alcoholic jAicric acid it yields a picrate, A diich crystallises from benzene-acetic acid and has had the folloAving oxonium constitution assigned to it —... 

When heated at 150° C. phenylmercuric acetate gives carbon, benzene, mercury, oxygen, and acetic anhydride. Dry distillation yields mercury, diphenyl oxide, and acetic anhydride. Distillation with sulphur gives mercury, benzene, acetic acid, acetic anhydride, and diphenyl sulphide. Boiling with dilute sulphuric or hydrochloric acid produces benzene, acetic acid, and a mercuric salt. The acetate is reduced by nascent hydrogen to benzene, mercury, and acetic acid. 

No solvent system resolves all the Dns-amino acids by one-dimensional chromatography and, also, TD chromatography requires more than two runs for a complete resolution. The most common used eluents on polyamide layers are benzene-acetic acid (9 1), toluene-acetic acid (9 1), toluene-ethanol-acetic acid (17 1 2), water-formic acid (200 3), water-ethanol-ammonium hydroxide (17 2 1 and 14 15 1), ethylacetate - ethanol- ammonium hydroxide... 

A widely employed chromatographic system is based on polyamide plates eluted with water-formic acid (200 3 v/v) in the first direction and benzene-acetic acid (9 1 v/v) in the second direction.
