Abstract

Aliphatic or cyclic epoxides containing 3 to 8 carbon atoms which are present in aromatic hydrocarbons or halohydrocarbons are saponified continuously and directly to vicinal diols without the use of high temperatures and pressures which would otherwise be necessary. The saponification is acid catalyzed.
