Amyl acetate (pentyl acetate) is an organic compound and an ester with the chemical formula CH 3 COO[CH 2] 4 CH 3 and the molecular weight 130.19 g/mol. It is colorless and has a scent similar to bananas [3] [4] and apples. [5] The compound is the condensation product of acetic acid and 1-pentanol.
sec-Amyl acetate is an organic compound and an ester. It is formed in an esterification reaction of sec -amyl alcohol (2-pentanol) and acetic acid . [ 2 ] It is a colorless liquid.
The ester formed from 1-pentanol and acetic acid is amyl acetate (also called pentyl acetate), which has a banana-like odor. It is a precursor to dipentyl zinc dithiophosphates, which are used in froth flotation. [3] In 2014, a study was conducted comparing the performance of diesel fuel blends with various proportions of pentanol as an additive.
Three of these alcohols, 2-methyl-1-butanol, 2-pentanol, and 3-methyl-2-butanol (methyl isopropyl carbinol), contain stereocenters, and are therefore chiral and optically active. The most important amyl alcohol is isoamyl alcohol , the chief one generated by fermentation in the production of alcoholic beverages and a constituent of fusel oil .
Alcohol oxidation is a collection of oxidation reactions in organic chemistry that convert alcohols to aldehydes, ketones, carboxylic acids, and esters. The reaction mainly applies to primary and secondary alcohols. Secondary alcohols form ketones, while primary alcohols form aldehydes or carboxylic acids. [1] A variety of oxidants can be used.
For example, in reacting ethanol with acetic anhydride, ethyl acetate forms and acetic acid is eliminated as a leaving group, which is considerably less reactive than an acid anhydride and will be left as a byproduct (in a wasteful 1:1 ratio with the ester product) if product is collected immediately. If conditions are acidic enough, the acetic ...
Transesterification is the process of exchanging the organic functional group R″ of an ester with the organic group R' of an alcohol. These reactions are often catalyzed by the addition of an acid or base catalyst. [1] Strong acids catalyze the reaction by donating a proton to the carbonyl group, thus making it a more potent electrophile.
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.
