ABSTRACT OF THE DISCLOSURE In the acid-catalyzed etherification of olefins with alcohols, substantially complete recovery of alcohol and catalyst is obtained when small amounts of water (1-10%) are added to the reaction. The addition of water provides a two-phase reaction medium in which olefin and ether are in the upper phase and alcohol and catalyst are in the lower phase. These phases are maintained during the course of the reaction, which continues as a two-phase system. Certain novel ethers produced by this process are likewise disclosed herein. These products are useful as paint additives, high octane gasoline additives and solvents.
