Propionic acid methyl ester is the methyl ester of propionic acid .

Extraction and presentation

Propionic acid methyl ester can be prepared by esterification of propionic acid with methanol are produced.

Industrial methyl propionate is produced by reacting ethene with carbon monoxide and methanol in the presence of nickel tetracarbonyl at 160 - 200 ° C and 50 bar.

Methyl propionate is used as a solvent for lacquers and as a base for further syntheses (e.g. that of methyl methacrylate , the monomer in acrylic glass ). Due to its rum-like smell and taste , it is also used as a fragrance and aroma .
