A trimethylsilyl group (abbreviated TMS) is a functional group in organic chemistry.This group consists of three methyl groups bonded to a silicon atom [−Si(CH 3) 3], which is in turn bonded to the rest of a molecule.
In organic chemistry, butyl is a four-carbon alkyl radical or substituent group with general chemical formula −C 4 H 9, derived from either of the two isomers (n-butane and isobutane) of butane. The isomer n -butane can connect in two ways, giving rise to two "-butyl" groups:
The general structure is R 1 R 2 R 3 Si−O−R 4 where R 4 is an alkyl group or an aryl group. Silyl ethers are usually used as protecting groups for alcohols in organic synthesis . Since R 1 R 2 R 3 can be combinations of differing groups which can be varied in order to provide a number of silyl ethers, this group of chemical compounds ...
The molecular formula C 8 H 14 O 4 may refer to: Diethyl succinate; Dimethyl_adipate; Ethyl acetoxy butanoate; Fructone; Suberic acid; 2,2,3,3-Tetramethylsuccinic acid
Ethyl butyrate, also known as ethyl butanoate, or butyric ether, is an ester with the chemical formula CH 3 CH 2 CH 2 COOCH 2 CH 3. It is soluble in propylene glycol, paraffin oil, and kerosene. It has a fruity odor, similar to pineapple, and is a key ingredient used as a flavor enhancer in processed orange juices. [1]
The heat of evaporation is 45.64 kJ·mol −1, the evaporation entropy 123 J·K −1 ·mol −1. [2] The vapor pressure function according to Antoine is obtained as log 10 (P/1 bar) = A − B/(T + C) (P in bar, T in K) with A = 5.44591, B = 1767.766 K and C = −44.888 K in a temperature range from 291 K to 358 K. [ 2 ] Below the melting point ...
The butyrate or butanoate ion, C 3 H 7 COO −, is the conjugate base of butyric acid. It is the form found in biological systems at physiological pH . A butyric (or butanoic) compound is a carboxylate salt or ester of butyric acid.
