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.
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.
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.

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).
In naming simple alcohols, the name of the alkane chain loses the terminal e and adds the suffix -ol, e.g., as in "ethanol" from the alkane chain name "ethane". [19] When necessary, the position of the hydroxyl group is indicated by a number between the alkane name and the -ol: propan-1-ol for CH 3 CH 2 CH 2 OH, propan-2-ol for CH 3 CH(OH)CH 3.
2-Pentanol (IUPAC name: pentan-2-ol; also called sec-amyl alcohol) is an organic chemical compound.It is used as a solvent and an intermediate in the manufacturing of other chemicals. 2-Pentanol is a component of many mixtures of amyl alcohols sold industrially. 2-Pentanol is chiral and thus can be obtained as either of two stereoisomers designated as (R)-(−)-2-pentanol and (S)-(+)-2-pentanol.
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 ...
