Abstract
A process for the separation and recovery of methyl tertiary butyl ether from mixed C4/C,streams, such as resulting from the co-production of methyl tertiary butyl ether and tertiary amyl methyl ether from the reaction of methanol with isobutene and isoamylenes in a mixed C,/C,stream. In a distillation column reactor the reaction is carried out concurrently with distillation of the products from the unreacted materials. In the distillation little or no MTBE is carried overhead with the unreacted C,'s, C,'s and methanol by controlling the methanol concentration in said column to maintain substantially a methanol/C,azeotrope in the overheads.
