Propyl acetate carbonate

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.

The photoreactions of saturated five-membered heterocycles are generally characterized by initial carbon-heteroatom bond homolysis. Tetrahydro-furans150 and 1,3-dioxolans151 behave in this way, and the major photoproducts of 2,2-dimethyl-1,3-dioxolan, for example, are acetone, propyl acetate, ethylene, acetaldehyde, methyl acetate, and oxiran. The vinyltetrahy-drofuran (180) is converted on irradiation in methanol to the ketal (181) and the ketone (182) by way of a Wagner-Meerwein shift in the carbocation... 

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). 

After 9 hr nearly equal amounts of butyric and isobutyric acid are formed (90-99% yield). The major by-product formed is propyl acetate, especially at higher temperatures. At 250°C, ethylene in an acetic acid solvent, gives an equimolar mixture of propionic anhydride and the mixed anhydride of acetic and propionic acid. The activity of the Pd on carbon catalyst drops slowly through repeated usage owing to slight but continuous solubilization of the palladium. The problem of long-term activity remains unsolved.

Among the organic compounds, toxicity shows a general pattern of decrease with an increase in the carbon chain length. However, such a pattern is manifested above carbon 6 or 7 (C-6 or C-7) for many classes of compounds. Below carbon 6 (C-6), certain substances, such as aliphatic esters, show enhanced toxicity with an increase in the carbon chain length. Thus n-amyl or n-butyl acetates are more toxic than ethyl or n-propyl acetates. The first members of certain classes...

In the long continued fractionation with the plain still-head, a considerable amount of moisture was absorbed by the esters and some hydrolysis took place.. Before the fractionations were completed it was necessary to treat the propyl acetate with potassium carbonate- and the methyl acetate with phosphorus pentoxide, and the loss was thus increased.
