Procedure for the synthesis of Allyl carbonates of alcoho les Polyhydric and its derivatives

摘要

Production process of Carbonic Allyl Ester of formula (i), from being a Polyhydric alcohols, R radical hidrocarburico. Is reacted at temperature of 50 - 150 C., and pressure of 10 mm. 760 mm HgHG Diallyl carbonate with an alcohol in the presence of a suitable plihidrico, 0.1 - 1 100 ppm by weight of alcohol, a basic Catalyst, such as Sodium Hydroxide, sodium alcloholato or others. The carbonate - Diallyl alcohol molar ratio is 2 - 20 - 1. The resulting ALLYL ALCOHOL is removed from the mixture by distillation. The residue is filtered, washed with water and become Dehydrated.Application to the fabrication of organic glass substitutes for optical applications.
