Abstract

NEW MATERIAL:A compound of formulaI(R is 1W6C alkyl other than ethyl, 2W6C alkenyl).
EXAMPLE: 2-Methyl 2-mercaptopropionate.
USE: A durable flavor and taste imparting agent usable for foods, drinks, cosmetics, healthy and hygienic use, medicines, etc.
PROCESS: A 2-mercaptopropionic acid of formula II (R' is H, 1W6C alkyl or 2W 6C alkenyl) is esterified with an aliphatic alcohol of the formula R'(OH) in the presence of a catalyst, e.g. an inorganic acid such as sulfuric acid or organic acid such as acetic acid, in an azeotropic solvent, e.g. benzene, at 60W100°C to give the compound of formulaIeasily in high purity and yield. The molar amount of the aliphatic alcohol to be used is 1W20 times, preferably 2W5 times, that of the compound of formula II. The amount of the catalyst to be used is 0.1W10wt% based on the compound of formula II.
