FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing 1,3-butadiene. Method includes: i) providing a catalyst on a support, containing lanthanum, zirconium and zinc, wherein support contains silicon dioxide; and ii) bringing into contact starting materials, containing ethanol, with catalyst on support to obtain raw product, containing 1,3-butadiene. Invention also relates to use of lanthanum in a catalyst for producing 1,3-butadiene.
EFFECT: present method provides favourable conversion and selectivity with respect to 1,3-butadiene.
