FIELD: chemistry.
SUBSTANCE: disclosed is a method of producing butadiene-1,3, involving reaction of formaldehyde-containing material with propylene in the presence of a solid-phase catalyst in gas-phase condensation conditions at atmospheric pressure. Catalyst used is a heteropolyacid selected from: 12-phosphotungsten, 12-tungsten-silicic, 12-phosphomolybdic, contained in amount of 5 to 99 wt. % on porous carrier.
EFFECT: simplification of the process due to its carrying out in a single step, as well as high output of the end product and selectivity of butadiene formation with high stability of catalyst operation in time.
