PRODUCTION OF 1,3-PROPANEDIOL - Mitsubishi Gas Chemical Co., Ltd.

Title:

PRODUCTION OF 1,3-PROPANEDIOL

Document Type and Number:

Japanese Patent JP3781059

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To produce 1,3-propanediol which is useful as a raw material of polyester by hydrogenating glycidaldehyde in the presence of a catalyst.
SOLUTION: The hydrogenation reaction of (A) glycidaldehyde is carried out in (B) an aqueous solution containing alcohols (preferably the alcohol concentration is 15-80wt.% based on the reaction mixture and the alcohol is 1-10C mono-ol, diol car triol in the presence of (C) a nickel catalyst, preferably Raney nickel at pH7.7-9.8, preferably 8.7-9.7 to give this objective 1,3-propanediol. The component A is preferably in the form of an aqueous solution of glycidaldehyde containing ≤3% hydrogen peroxide remaining after epoxidation of acrolein with hydrogen peroxide in a weakly basic aqueous medium.
