    en.wikipedia.org/wiki/Amyl_acetate

    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.

    en.wikipedia.org/wiki/Sec-Amyl_acetate

    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.

  4. 1-Pentanol - Wikipedia

    en.wikipedia.org/wiki/1-Pentanol

    The ester formed from 1-pentanol and butyric acid is pentyl butyrate, which has an apricot-like odor. 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]

  5. Amyl alcohol - Wikipedia

    en.wikipedia.org/wiki/Amyl_alcohol

    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 .

    An ester of carboxylic acid.R stands for any group (organic or inorganic) and R′ stands for organyl group.. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (−R).

    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.

  9. Fischer–Speier esterification - Wikipedia

    en.wikipedia.org/wiki/Fischer–Speier...

    Over time, the acidity of the acetic acid and tannins in an aging wine will catalytically protonate other organic acids (including acetic acid itself), encouraging ethanol to react as a nucleophile. As a result, ethyl acetate—the ester of ethanol and acetic acid—is the most abundant ester in wines. Other combinations of organic alcohols ...
