An improvement in a method for cogeneration of isobutylene and MTBE by etherification of tBA/MeOH over an ion-exchange resin which allows for more complete conversion of the remaining tBA fraction and comprises a second step consisting essentially of the MTBE from the primary fractionator as an overhead fraction and etherifying the bottoms from the primary fractionator over an inorganic acid catalyst comprising a crystalline aluminosilicate faujasite-type Y-zeolite modified with a fluoride-containing compound.
