FIELD: industrial organic synthesis.
SUBSTANCE: invention provides a method for preparing improved oxirane hydroformylation catalyst, improved oxirane hydroformylation catalyst, and single-stage process for production of 1,3-diol in presence of such catalyst. Preparation of catalyst comprises preparing complex A by contacting ruthenium(0) compound with di-tertiary phosphine ligand and preparing complex B via redox reaction of complex A with cobalt(0) carbonyl compound. Single-stage 1,3-diol production process involves reaction of oxirane with synthesis gas under hydroformylation conditions in inert solvent in presence of aforesaid catalyst, where recovery of product is preferably accomplished through separation of product-rich phase.
EFFECT: reduced number of stages to a single one or increased yield of 1,3-diol without by-products and preserved catalytic activity after catalyst regeneration operation.
