Abstract
1,3-Propanediol is manufactured by the hydration of acrolein in an aqueous solution over a fully hydrated, alumina-bound zeolite with a pore size >5 angstroms to form 3-hydroxypropanal and hydrogenation of the 3-hydroxypropanal typically in an aqueous solution in the presence of a nickel catalyst.
