Methyl propionate, also known as methyl propanoate, is an organic compound with the molecular formula CH3CH2CO2CH3. It is a colorless liquid with a fruity, rum-like odor.[2]
Methyl propionate can be prepared by esterificationofpropionic acid with methanol. Industrially, it is prepared by carboalkoxylation, i.e., the reaction of ethylene with carbon monoxide and methanol in the presence of a catalyst:
The reaction is catalyzed by nickel carbonyl and palladium(0) complexes.[3][4]
Condensation of Methyl propionate with formaldehyde followed by dehydration yields methyl methacrylate:[4]
Methyl propionate is used as a solvent for cellulose nitrate and lacquers, and as a raw material for the production of paints, varnishes and other chemicals such as methyl methacrylate.[2][3]
Due to its fruity smell and taste, it is also used in fragrances and flavoring.[2][5]
