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.
