| titleOfInvention | One step hydroformylation and hydrogenation process for preparing a 1,3-propanediol |
| abstract | Process for one-step hydroformylation and hydrogenation synthesis of 1,3-propanediol which comprises: (a) contacting a mixture of ethylene, oxide, carbon monoxide, hydrogen, a non-water-mixcible reaction solvent and a hydroformylation catalyst composition; (b) heating said reaction mixture to produce a single-phase reaction product mixture containing 1,3-propanediol such that phase separation can be induced by temperature reduction; and (c) inducing phase separation by at least one method selected from the group consisting of: (i) temperature reduction combined with addition of a phase split-inducing agent to the mixture, (ii) temperature reduction combined with first adding a miscibilizing cosolvent and then removing the miscibilizing cosolvent, (iii) first adding a miscibilizing cosolvent and then removing the miscibilizing cosolvent, and (iv) adding a phase split-inducing agent to the reaction product mixture wherein the phase separation results in a first phase comprising a major portion of the reaction solvent, at least 50 wt% of the catalyst composition, plus unreacted ethylene oxide, and a second phase, which comprises a major portion of 1,3-propanediol. |
