Abstract
L'INVENTION CONCERNE UN PROCEDE DE PURIFICATION D'UNE CETONE OBTENUE PAR DESHYDROGENATION DE L'ALCOOL SECONDAIRE CORRESPONDANT ET QUI RENFERME DE L'EAU ET DE L'ALCOOL NON CONVERTI. LE PROCEDE EST CARACTERISE EN CE QUE L'ON SOUMET LE MELANGE A PURIFIER A UNE DISTILLATION EN PRESENCE D'UN HYDROCARBURE SATURE LEGER QUI FORME UN AZEOTROPE AVEC L'EAU, LES AUTRES IMPURETES ETANT ELIMINEES PAR DES DISTILLATIONS SIMPLES. L'INVENTION EST APPLICABLE, EN PARTICULIER A LA PURIFICATION DE LA METHYLETHYLCETONE.
