ABSTRACT:
A process for producing 1,3-propanediol, comprising:hydrating acrolein in a liquid phase in the presence of a hydration catalyst to form 3-hydroxypropanal;separating any unreacted acrolein, if any is present; andcarrying out catalytic hydrogenation of the 3-hydroxypropanal in a liquid or gas phase with a hydrogenation catalyst,wherein the hydration catalyst is a catalyst comprising at least one member selected from the group consisting of the following materials (a) to (c) and has a pH of 6 or less at 20° C., when made into a slurry by dispersing the catalyst in a quantity of water 5 times as much as the quantity of catalyst by weight:(a) a metalloaluminophosphate molecular sieve,(b) an FER type zeolite, and(c) an oxide or compound oxide, excluding crystalline aluminosilicate zeolites, which comprises one or more element(s) selected from the elements belonging to group 4, group 13 and group 14 of the periodic table.
