Abstract

Procédé d'obtention d'isophorone incolore stable consistant à distiller le mélange brut de synthèse en vue d'éliminer la soude, l'acétone et la majeure partie de l'eau, puis à effectuer sur le mélange ainsi obtenu, à chaud, un traitement par une résine échangeuse d'ions acide fort sous forme acide, éventuellement séchée, suivi d'une distillation sous pression réduite.
