Abstract:
A process for the production of tertiary alkyl ethers which comprises(1) providing a liquid hydrocarbon feed comprising C.sub.4 to C.sub.6 tertiary olefins and a nitrogen-containing impurity(2) contacting the hydrocarbon feed with an alcohol selected from methanol, ethanol or mixtures thereof(3) distilling the hydrocarbon feed/alcohol mixture and removing the nitrogen-containing impurity as a fraction with a higher boiling point than a fraction containing the C.sub.4 to C.sub.6 tertiary olefins(4) reacting the fraction containing the C.sub.4 to C.sub.6 tertiary olefins with the alcohol over an acid catalyst to produce the corresponding tertiary alkyl ether.
