Abstract

PURPOSE: To obtain the subject compound useful as an intermediate raw material for additives of organic polymer resins in high yield by hydrolyzing a thiodialkylnitrile in the presence of a mineral acid.
CONSTITUTION: A thiodialkylnitrile is hydrolyzed in the presence of a mineral acid (especially hydrochloric acid) as a reaction accelerator at 90-120°C temperature to afford a thiodialkylcarboxylic acid expressed by the formula (R1, and R2 are H or 1-3C alkyl; (n) is 0-3). The mineral acid is used in an amount of preferably 2.2-10.0mol, especially 3.0-5.0 based on 1mol raw material nitrile.
