FIELD: organic chemistry, chemical technology.
SUBSTANCE: invention relates to the improved method for preparing concentrate of butyric aldehydes by oxonation. Method is carried out by the hydroformylation reaction of propylene with synthesis-gas in two in-line connected reactors at temperature 120-150°C, under pressure 250-300 kgf/cm2 and with heat removing by circulation of cooling agent through Field's tubes installed in hydroformylation reactors followed by separation of reaction products. The hydroformylation process in the first reactor is carried out in regimen when the ratio of volume consumptions of cooling agent circulating in Field's tubes and propylene feeding into reactor is (18-28):1. Invention provides enhancing yield of end products, improving energetic indices due to effective heat transfer in the hydroformylation reactor.
EFFECT: improved preparing method.
