Propyl acetate benzene

Overview. The capillary column IGC technique was used to determine the partition coefficients and diffusion coefficients of a number of solvents (methanol, acetone, methyl acetate, ethyl acetate, propyl acetate, benzene, toluene, and ethylbenzene) in poly(methyl methacrylate). Measurements below the glass transition temperature were obtained for the PMMA/methanol system.

Comparing equations 13.8 and 13.9, it is seen that the adiabatic saturation temperature i > equal to the wet-bulb temperature when s = h/hDpA. This is the case for most water vapour systems and accurately so when Jf = 0.047. The ratio (h/hopAs) = b is sometimes known as the psychrometric ratio and, as indicated, b is approximately unity for the air-water system. For most systems involving air and an organic liquid, b = 1.3 - 2.5 and the wet-bulb temperature is higher than the adiabatic saturation temperature. This was confirmed in 1932 by SHERWOOD and COMINGS 2 who worked with water, ethanol, n-propanol, n-butanol, benzene, toluene, carbon tetrachloride, and n-propyl acetate, and found that the wet-bulb temperature was always higher than the adiabatic saturation temperature except in the case of water. 

P-Diethyl amino ethyl diphenyl propyl acetate hydrogen chloride (SKF-525A) and toluene have inhibited benzene metabolism in rats (Gill et al. 1979 Ikeda et al. 1972). Carbon monoxide, aniline, aminopyrine, cytochrome C, and metapyrene inhibit benzene metabolism in mouse liver microsomes (Gonasun et al. 1973). Ethanol ingestion as well as dietary factors such as food deprivation and carbohydrate restriction, enhance the in vitro metabolism of benzene in rat liver microsomes (Nakajima et al. 1987).

Final Fractionations.— Tho fractions into which the esters had been separated at the end of the 2Gth fractionation are shown in Table 39. The total weight was 490-8 grams, and therefore 86 grams had been lost by evaporation and by transference from flask to still. The final separation of methyl and ethyl acetates and of ethyl and propyl acetates was carried out in the manner described for the later fractionations of mixtures of benzene and toluene, but it was necessary to treat the methyl acetate with phosphorus pentoxide to remove moisture, and the propyl acetate with...
