ABSTRACT:
Dimethyl ether is prepared by feeding a mixture of CO, CO.sub.2 and H.sub.2, wherein the quantity of CO is in excess of the stoichiometric value, to a reactor containing a methyl alcohol synthesis catalyst, such as a copper base or chrome-zinc base catalyst, and a methyl alcohol dehydration catalyst, such as alumina, whereby methyl alcohol is formed as an intermediate product which is transformed into dimethyl ether in the same reactor at a temperature in the range of 220.degree. to 400.degree. C and a pressure in the range of 30 to 500 kg/cm.sup.2.
