Abstract
Pure dimethyl ether is prepared by catalytic dehydration of methanol over a gamma -Al2O3 catalyst which preferably contains small amounts of SiO2 and purification of the dehydration product by addition thereof to a distillation column to obtain pure dimethyl ether on certain plates of this column and taking off the pure dimethyl ether and impurities above certain plates of the same column.
