Abstract: Method for increasing the yield of a polyhydric alcohol (I) produced by hydrogenating a methylolated alkanol comprises transesterifying a formate ester of (I) with an alcohol (II) in the presence of a tertiary amine catalyst. Method for increasing the yield of a polyhydric alcohol (I) produced by hydrogenating a methylolated alkanal comprises transesterifying a formate ester of (I) with an alcohol (II) in the presence of a tertiary amine catalyst selected from: (a) compounds of formula R R R N (III); (b) heterocyclic tertiary amines. R -R = 1-12C alkyl, 3-12C cycloalkyl or aryl, all optionally substituted.
