Abstract
1,3-Propanediol is prepared in good yield by hydrogenation of methyl 3-hydroxypropionate in the presence of a copper zinc oxide hydrogenation catalyst. The use of the copper zinc oxide hydrogenation catalyst enables greater productivity in an overall process for preparing 1,3-propanediol from ethylene oxide via methyl 3-hydroxypropionate intermediate.
