Abstract
A process for producing tertiary alkyl ethers by reacting an olefinic hydrocarbon feedstock, which contains a mixture of reactive C.sub.4 -C.sub.7 isoolefins, with an alkanol in the presence of a catalyst that will enhance the reaction between the isoolefins and the alkanol. By adjusting the weight ratio of the isobutylene to the reactive C.sub.6 isoolefins of the feed to a value of about 0.2 to 10, it is possible to increase the conversion of reactive C.sub.4 's to over 95%, of reactive C.sub.5 's to over 85% and of reactive C.sub.6 's to over 57%.
