Abstract

There is provided a process for the continuous production of pentanediol-1,2 comprising epoxidizing pentene in a completely homogeneous phase with perpropionic acid in benzene to 1-pentene oxide and directly saponifying the pentene oxide-1 without isolation. High yields and a high degree of purity of pentanediol-1,2 are obtained.
