FIELD: industrial organic synthesis. n SUBSTANCE: invention relates to synthesis of aliphatic 1,3-diol, especially 1,3-propanediol from ethylene oxide and syngas in one step. More specifically, invention relates to catalytic composition, which ensures good yield under mild conditions in single-step 1,3-propanediol synthesis process and manifests advantages regarding expenses and efficiency. Catalytic composition comprises cobalt component including one or more non-alloyed cobalt compounds and ruthenium component including mainly ruthenium carbonyl compound alloyed with phospholanoalkane ligand. Single-step 1,3-propanediol synthesis process is carried out in presence of catalytic composition at 30 to 150°C and pressure at least 690 kPa over a period of time long enough to obtain two-phase reaction product mixture including upper phase containing major part of solvent, at least 50% of catalytic composition and unconverted ethylene oxide and lower phase containing major part of 1,3-propanediol. n EFFECT: enhanced process efficiency and reduced expenses. n 10 cl, 4 tbl, 17 ex |
