ABSTRACT:
An alkyl t-alkyl ether corresponding to the formula R--O--R', wherein R is a methyl or ethyl group and R' is a t-butyl or t-amyl group, is separated from the alkanol in a reactor effluent comprising a mixture of the ether, unreacted C.sub.1 -C.sub.2 alkanol, and unreacted hydrocarbon by (1) alternately passing effluent from the reactor through first and second absorption vessels containing fixed beds of solid calcium chloride to complex the unreacted alkanol with the calcium chloride while the ether and unreacted hydrocarbon pass through the vessel, (2) while one absorption vessel is being used to complex unreacted alkanol, regenerating the other absorption vessel by passing a liquid C.sub.4 or C.sub.5 hydrocarbon feed comprising an isoolefin therethrough at a temperature of about 80.degree.-120.degree. C. to desorb the alkanol and provide a desorption effluent of liquid C.sub.4 or C.sub.5 hydrocarbon feed and alkanol, and (3) feeding the desorption effluent to the reactor.
