FIELD: chemical industry. SUBSTANCE: described is method of preparing 1,3-alkanediols and 3- hydroxyaldehydes by hydroformylation of oxirane with carbon monoxide and hydrogen in the presence of catalyst based on cobalt and promoter which is lipophilic tetrasubstituted salt of V group element selected from nitrogen, phosphorus and arsenic. EFFECT: high yield and selectivity of 1,3-propanediol, higher hydroformylation rate and greater possibility of recirculation of catalyst. 9 cl, 1 dwg, 8 ex, 4 tbl |
