Abstract: Procédé de désodorisation d'un mercaptoacide de formule HS-A-COOH dans laquelle A est: -(CH2)n- ; ou dans lequel on extrait la majeure partie des composés malodorants de décomposition du mercaptoacide à l'aide d'un fluide supercritique constitué d'un composé dont la température critique est comprise entre 0 et 135.degree. C et la pression critique entxe 10 6 et 10 7 pascals, l'extraction étant effectuée en présence d'au moins un solvant polaire du mercaptoacide. Produit désodorisé obtenu.

Abstract: Method for deodorising a mercaptoacid of formula HS-A-COOH, in which formula A represents: -(CH2)n-; 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.

Abstract: Method of deodorising a mercaptoacid of formula HS-A-COOH in which A is: -(CH2)n-; in which most of the malodorous decomposition compounds of the mercaptoacid are extracted using a supercritical fluid consisting of a compound of which the critical temperature is between 0 and 135@C and the critical pressure is between 10 and 10 pascals, the extraction being carried out in the presence of at least one polar solvent of the mercaptoacid. Deodorised product obtained.
