Abstract
A process for preparing oxirane compounds by the deacyloxylation of a vicinal hydroxyester in the presence of a basic material which comprises carrying out the reaction in a dilute phase transport reactor into which is fed a stream of heated catalyst co-current with a feed gas stream. The catalyst is heated in a fluidized bed heater. The catalyst and product gases are separated in a cyclone separator, the catalyst being returned to the heater and the effluent product gas being further processed to recover product.
Claims13
In a process for preparing an oxirane compound by the deacyloxylation of a vicinal hydroxyester using as a catalyst a basic material, the improvement which comprises carrying out the process continuously in a dilute phase transport reactor by:
- (a) heating a fluidized bed of catalyst in a heating zone to the temperature necessary for carrying out the deacyloxylation process;
- (b) introducing said heated catalyst and a preheated feed gas stream into the reactor, wherein the deacyloxylation of a vicinal hydroxyester component of the feed gas is accomplished, thereby producing an oxirane compound;
- (c) separating the reacted gas stream from the catalyst;
- (d) returning the catalyst to the heating zone for reheating;
- and
- (e) further processing the reacted gas stream to separate out the oxirane product.
