Claim 2
Dependent Claim
66 words
The catalyst composition for preparing a polyhydric alcohol by the conversion of a mixture consisting essentially of an oxide of carbon and hydrogen to said alcohol, which catalyst is a rhodium carbonyl complex formed in the presence of said mixture at a temperature of between 100° and 375° C. and at a pressure of between 500 to 50,000 psig of said oxides of carbon and hydrogen.
Claim 3
Dependent Claim
