CATALYTIC CONVERSIONS OF PROPYLENE-GLYCOL ACETATES IN A POTASSIUM ACETATE MELT

The cyclization of glycol acetates to oxiranes generally occurs with t he participation of strongly basic catalysts [1-4]. Earlier it was est ablished that contacts produced by impregnating silicas (for example, diatomite) with alkali solutions are active and selective in the cycli zation of glycol acetates [5, 6]. Since, over the course of their conv ersion, acetic acid is eliminated and neutralization of highly basic c entres of the catalyst occurs with the formation on its surface of alk ali metal acetate, it is of interest to establish the influence of the latter (for example, potassium acetate) on the catalytic conversions of glycol acetates.
