Abstract
A process for producing ethanol which comprises reacting methanol, carbon monoxide and hydrogen in the presence of a catalyst comprising a cobalt phosphine carbonyl complex having the formula: Co(CO).sub.3.R.sub.1 R.sub.2 R.sub.3 P.R.sub.4 R.sub.5 PO wherein each of R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 is independently hydrogen, C.sub.1 -C.sub.20 alkyl, C.sub.3 -C.sub.20 cycloalkyl or aryl, and the alkyl, cycloalkyl or aryl may contain a member selected from N, O, S, halogen and mixtures thereof is disclosed.
Claims3
A process for producing ethanol which comprises reacting methanol, carbon monoxide and hydrogen in the presence of a catalyst effective component separated through chromatography from the reaction mixture of a cobalt compound and a phosphine, the catalyst comprising a cobalt phosphine carbonyl complex having the formula:
- Co(CO).sub.3.R.sub.1 R.sub.2 R.sub.3 P.R.sub.4 R.sub.5 PO
- wherein each of R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 is independently hydrogen, C.sub.1 -C.sub.20 alkyl, C.sub.3 -C.sub.20 cycloalkyl or aryl, and the alkyl, cycloalkyl or aryl may contain a member selected from N, O, S, halogen and mixtures thereof.
