A method for conducting chemical reactions and fractionation of the reaction mixture comprising feeding reactants to a distillation column reactor into a feed zone and concurrently contacting the reactants with a fixed bed catalytic packing to concurrently carry out the reaction and fractionate the reaction mixture, said catalytic packing being a component of distillation system having both a catalytic function and a distillation function. For example, a method for preparing methyl tertiary butyl ether in high purity from a mixed feed stream of isobutene and normal butene comprising feeding the mixed feed stream to a distillation column reactor into a feed zone at the lower end of a distillation zone, and methanol into the upper end of said distillation reaction zone, which is packed with a properly supported cationic ion exchange resin, contacting the C4 feed and methanol with the catalytic distillation packing to react methanol and isobutene, and concurrentl fractionating the ether from the column below the catalytic zone and removing normal butene overhead above the catalytic zone. |
