A process for the preparation of a primary or secondary alcohol, which comprises hydrogenating respectively an aldehyde or ketone in the presence of a catalyst system comprising a platinum compound, an acid having a pKa in the range from about 2 to about 10.5 and a phosphorus compound of the formula

A process for the preparation of a primary or secondary alcohol, which comprises hydrogenating respectively an aldehyde or ketone in the presence of a catalyst system comprising a platinum compound, an acid having a pKa in the range from about 2 to about 10.5 and a phosphorus compound of the formula R1R2POH, wherein R1 and R2 each independently represents an alkyl group or a phenyl group, at a temperature in the range from about 20°to about 150°C. and at a pressure in the range from about 1 to about 100 bar.

A process for the preparation of alcohols, which comprises contacting and reacting hydrogen with a carbonyl reactant comprising one or more compounds selected from the group consisting of aldehydes of the formula R3CHO and ketones of the formula R3COR4, wherein R3 and R4 each is independently select

A process for the preparation of alcohols, which comprises contacting and reacting hydrogen with a carbonyl reactant comprising one or more compounds selected from the group consisting of aldehydes of the formula R3CHO and ketones of the formula R3COR4, wherein R3 and R4 each is independently selected from the group consisting of substituted and unsubstituted alkyl, alkenyl, cycloalkyl and cycloalkenyl moieties having from 1 to about 10 carbon atoms or a phenyl group, in the presence of a catalyst system comprising a platinum compound, an acid having a pKa in the range of from about 2 to about 10.5 and a phosphorus compound of the formula R1R2POH, wherein R1 and R2 each independently represents a C1 to C10 alkyl group or a phenyl group, at a temperature in the range from about 20 to about 150°C. and at a pressure in the range from about 1 to about 100 bar.
