Abstract
A process for the catalytic hydrogenolysis of glycerol in the presence of a homogeneous catalyst that is based on a platinum group metal or a compound of a platinum group metal, an anion source, and a metal-complexing compound of the formula Q.sup.1 Q.sup.2 MQ.sup.3 (I) or Q.sup.1 Q.sup.2 MQMQ.sup.3 Q.sup.4 (II) wherein M represents phosphorus, arsenic or antimony, Q represents a group that is covalently bonded to both M's and having at least two carbon atoms in the bridge and Q.sup.1 to Q.sup.4 are independently similar or dissimilar optionally substituted hydrocarbyl groups or Q.sup.1 and Q.sup.2 and/or Q.sup.3 and Q.sup.4 represent similar or dissimilar optionally substituted hydrocarbylene groups.
