METHOD OF COMBINED SYNTHESIS OF MONO- AND DIPRORYLENE GLYCOLS Russian patent published in 1999 - IPC

Abstract RU 2137744 C1

FIELD: organic chemistry and chemical technology. SUBSTANCE: mono- and dipropylene glycols are synthesized by hydration of propylene oxide by step-by-step increase of temperature from 80-120 C to 170-220 C in the presence of an alkaline catalyst. Method provides the selective increase of synthesis of propylene glycol and the preferred formation of a single isomer of propylene glycol. EFFECT: selective synthesis of isomer of propylene glycol. 2 cl, 7 ex
