ABSTRACT:
In a process for the preparation of allylic ethers which comprises contacting and reacting an allylic alcohol reactant comprising one or more C.sub.6 to C.sub.20 allylic alcohols with a glycol reactant comprises one or more C.sub.2 or C.sub.3 alkylene glycols and their polyalkylene glycols in the presence of a cuprous salt catalyst and an acidic co-catalyst, the invention is the improvement which comprises contacting the allylic alcohol and alkylene glycol reactants in an agitated reaction mixture containing a solvent for the allylic alcohol reactant and the ether product which is substantially immiscible with the alkylene glycol reactant, said solvent being present in the reaction mixture in a quantity by weight which is at least about three times the weight of the allylic alcohol reactant. The improvement of the invention substantially increases the selectivity of the process for the production of the allylic ethers.
