Abstract
Methanol is catalytically produced from a synthesis gas which contains H.sub.2, CO and CO.sub.2 in a synthesis reactor at temperatures from 220.degree. to 300.degree. C. and under a pressure in the range from 20 to 120 bars. A product mixture which contains methyl formate is withdrawn from the synthesis reactor and is cooled to temperatures in the range from 20.degree. to 60.degree. to provide a condensate which contains methanol, water and methylformate. A gas mixture which contains H.sub.2, CO and CO.sub.2 is formed at the same time. A fraction which comprises 10 to 100% by weight methyl formate is separated from the condensate and is admixed with the synthesis gas which is fed to the synthesis reactor.
