摘要
In the reaction of methanol and of i-butene which is contained in a hydrocarbon mixture on an acid cation exchange material to give methyl tert.-butyl ether (MTBE), methanol and i-butene can be used in essentially equimolar amounts if simultaneously to the distillative separation of the etherification mixture into its constituents this etherification mixture is passed into a secondary reaction. To do this, the etherification mixture is fed into a distillation column and from above the feed-in point a liquid distillate stream is taken off and passed in a secondary reactor over an acid cation exchange material. The mixture leaving the secondary reactor is returned below its take-off point.
