Abstract
Tertiary butyl alcohol and methanol are reacted in a primary reactor in the presence of an acid cation exchange resin to provide a primary reaction product comprising methyl tertiary butyl ether, unreacted tertiary butyl alcohol, unreacted methanol, isobutylene, water and oxygen-containing by-products, and the primary reaction product is charged to a reactive distillation column where additional methyl tertiary butyl ether is prepared from the methanol, tertiary butyl alcohol and isobutylene present in the primary reaction product.
