PROCESS FOR PRODUCING TERTIARY ALKYL-ETHERS AND APPARATUS FOR REACTIVE DISTILLATION

摘要

A process for the preparation of tertiary alkyl ethers, in particular methyl-tert.-butyl-ether (MTBE), from iso-olefins and aliphatic alcohols by means of a fractionation tower is disclosed, in which the main characteristic of the fractionation tower consists in that the reaction mixture is caused to flow through the catalytic trays in transversal direction relatively to the axis of the same fractionation tower.
