Nitrate esters, such as nitroglycerin, are known for their explosive properties, while polyesters are important plastics, with monomers linked by ester moieties. Esters of carboxylic acids usually have a sweet smell and are considered high-quality solvents for a broad array of plastics, plasticizers, resins, and lacquers. [2]
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]
Like many esters it has a fruity or floral smell at low concentrations and occurs naturally in raspberries, pears and other plants. At higher concentrations the odor can be unpleasant and may cause symptoms of central nervous system depression such as nausea , dizziness and headache .
Hexyl acetate is an ester with the molecular formula C 8 H 16 O 2.It is mainly used as a solvent for resins, polymers, fats and oils.It is also used as a paint additive to improve its dispersion on a surface.
n-Butyl acetate is an organic compound with the formula CH 3 CO 2 (CH 2) 3 CH 3.A colorless, flammable liquid, it is the ester derived from n-butanol and acetic acid.It is found in many types of fruit, where it imparts characteristic flavors and has a sweet smell of banana or apple.
Methyl anthranilate, also known as MA, methyl 2-aminobenzoate, or carbomethoxyaniline, is an ester of anthranilic acid. Its chemical formula is C 8 H 9 NO 2. It has a strong and fruity grape smell, and one of its key uses is as a flavoring agent.
Ethyl acetate (systematically ethyl ethanoate, commonly abbreviated EtOAc, ETAC or EA) is the organic compound with the formula CH 3 CO 2 CH 2 CH 3, simplified to C 4 H 8 O 2.This flammable, colorless liquid has a characteristic sweet smell (similar to pear drops) and is used in glues, nail polish removers, and the decaffeination process of tea and coffee.
Ethyl benzoate, C 9 H 10 O 2, is an ester formed by the condensation of benzoic acid and ethanol. It is a colorless liquid that is almost insoluble in water, but miscible with most organic solvents. As with many volatile esters, ethyl benzoate has a pleasant odor described as sweet, wintergreen, fruity, medicinal, cherry and grape. [1]
