ABSTRACT:
Methyl formate is prepared by converting methanol over a copper-containing catalyst at elevated temperatures and in the gas phase by a process in which the catalyst used contains from 30 to 80% by weight of copper, calculated as CuO, as well as from 20 to 70% by weight of a magnesium silicate, calculated as MgO plus SiO.sub.2, which has a molar ratio of MgO/SiO.sub.2 of from 0.3 to 1.5, and may additionally be doped with the metals zinc, chromium and/or barium, each in an amount of not more than 1.5% by weight, calculated as ZnO, Cr.sub.2 O.sub.3 and BaO.
