Abstract
Procédé de préparation en continu de diols vicinaux par saponification continue et directe d'époxyde aliphatique ou cyclique comportant 3 à 8 atomes de carbone en solution dans certains hydrocarbures, au moyen d'eau, sans utiliser des températures élevées ainsi que des pressions élevées qui sont généralement nécessaires pour obtenir des rendements élevés et une bonne sélectivité. La saponification est catalysée de manière acide.
