Abstract: Methanol is prepared by catalytic conversion of a synthesis gas mixture, containing hydrogen, carbon monoxide, carbon dioxide and/or water, at from 200 DEG to 320 DEG C. and under from 30 to 300 bar in adiabatic and/or isothermal reactions in the presence of a catalyst containing copper and zinc, by a process in which the fresh catalyst is reduced with a hydrogen-containing gas before the start-up of the process, and then the synthesis is started under conventional conditions and is continued until the formation of methanol in the reaction zone has declined substantially, after which the reaction is interrupted and the catalyst is regenerated.

Abstract: Separation of basic inorganic compounds from the reaction mixture obtained in the manufacture of hydroxypivalic acid neopentylglycol ester (2,2-dimethyl-1,3-propanediol-hydroxypivalic monoester) by the addition of formic acid to the mixture obtained from the reaction of hydroxypivalaldehyde in the presence of basic catalysts, followed by filtration. The compound produced in the process of the invention is a valuable intermediate in the manufacture of polyesters, synthetic resins and plasticizers.
