| titleOfInvention | One step hydroformylation and hydrogenation process for preparing a 1,3-diol |
| abstract | Disclosed is a process for one-step hydroformylation and hydrogenation synthesis of 1,3-propanediol which comprises: (a) contacting in a reaction vessel a mixture ofethylene oxide, carbon monoxide, hydrogen, a non-water-miscible reaction solvent and a hydroformylation catalyst composition; (b) heating said reaction mixture to a temperature within the range from 30 to 150 DEG C and a pressure within the range of 0.7 to 27.6 MPa (100 to 4000 psi) for a time effective to produce a single-phase reaction product mixture containing sufficient concentration of 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 in an amount sufficient to induce phase separation, (ii) temperature reduction combined with first adding a miscibilizing cosolvent to keep the reaction product mixture in a single phase and then removing the miscibilizing cosolvent, (iii) first adding a miscibilizing cosolvent to keep the reaction product mixture in a single phase and then removing the miscibilizing cosolvent, and (iv) adding a phase split-inducing agent to the reaction product mixture in an amount sufficient to induce phase separation; 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. |
