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).
Ethyl salicylate is the ester formed by the condensation of salicylic acid and ethanol. It is a clear liquid that is sparingly soluble in water, but soluble in alcohol and ether. It has a pleasant odor resembling wintergreen and is used in perfumery and artificial flavors. [3]
Isobutyl formate (2-methylpropyl methanoate) is an organic ester with the chemical formula C 5 H 10 O 2. It is formed by the Fischer esterification of isobutanol with formic acid, with the aid of an acid catalyst. It is used as a flavor and fragrance ingredient because of its odor which is sweet, ethereal, and slightly fruity. [2] [3]
Ethyl octanoate, also known as ethyl caprylate, is a fatty acid ester formed from caprylic acid and ethanol.A colorless liquid at room temperature, it has the semi-developed formula of CH 3 (CH 2) 6 COOCH 2 CH 3, and is used in food industries as a flavoring and in the perfume industry as a scent additive.
Ethyl formate is an ester formed when ethanol (an alcohol) reacts with formic acid (a carboxylic acid). Ethyl formate has the characteristic smell of rum and is partially responsible for the flavor of raspberries , [ 3 ] occurring naturally in some plant oils, fruits, and juices.
It is an ester derived from the keto acid levulinic acid. Ethyl levulinate can also be obtained by reaction between ethanol and furfuryl alcohol . [ 3 ] These two synthesis options make ethyl levulinate a viable biofuel option, since both precursors can be obtained from biomass : levulinic acid from 6-carbon polymerized sugars such as cellulose ...
Methyl hexanoate is the fatty acid methyl ester of hexanoic acid (caproic acid), a colourless liquid organic compound with the chemical formula CH 3 −(CH 2) 4 −COO−CH 3. It is found naturally in many foods and has a role as a plant metabolite. It can also be found in the cytoplasm of cells. [1]
Ethyl lactate, also known as lactic acid ethyl ester, is the organic compound with the formula CH 3 CH(OH)CO 2 CH 2 CH 3. It is the ethyl ester of lactic acid. A colorless liquid, it is a chiral ester. Being naturally derived, it is readily available as a single enantiomer. It is commonly used as a solvent. [4]
