Method of deodorising a mercapto acid by extraction of malodorous compounds and deodorised product thus obtained.

摘要

Method for deodorising a mercaptoacid of formula HS-A-COOH, in which formula A represents: -(CH2)n-; <IMAGE> according to which most of the malodorous decomposition compounds of the mercaptoacid are extracted using carbon dioxide (CO2) in the gaseous, liquid or solid state. Deodorised product obtained. <IMAGE>
