VERFAHREN ZUR HERSTELLUNG VON ETHANOL UND N-PROPANOL AUS METHANOL

摘要

In a process for the production of ethanol and n-propanol by conversion of methanol with carbon monoxide and hydrogen in the presence of a catalyst containing cobalt, platinum, at least one halogen or halide, and an organic phosphine or phosphite, the improvement comprising the halogen or halide being chlorine or a chloride, and the phosphine or phosphite being bidentate. In addition, the conversion is carried out at pressures of 200 to 800 bars in the presence of 5 to 25% by weight of water, based on the methanol.
