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.
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 ...
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
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
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 half-life for the latter reaction is calculated to be 6.4 days. TMS itself is not expected to be susceptible to direct photolysis by sunlight. If TMS is hydrolyzed in air, this occurs within 3 minutes at 25 °C, which is much faster. Hydrolysis of TMS can also occur in water, but at a 10 times slower rate than in air: 0.3 minutes at 2 °C.
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]
Hagemann's ester, ethyl 2-methyl-4-oxo-2-cyclohexenecarboxylate, is an organic compound that was first prepared and described in 1893 by German chemist Carl Hagemann. The compound is used in organic chemistry as a reagent in the synthesis of many natural products including sterols , trisporic acids , and terpenoids .
