FIELD: chemistry.

SUBSTANCE: invention relates to the methods of production of catalysts used for the synthesis of isoprene; the method describes the catalyst used for the production of isoprene by means of interacting of methylal with the organic composition C₄ containing boron phosphate and at least one of the oxides and/or labile to oxides compositions chosen from the group of aluminum, magnesium, zinc, silicon characterized with that it additionally contains at least one of oxides and/or labile to oxides compositions chosen from the group of manganese, tungsten, tin monoxide, titanium, zirconia upon the following contents of components, % of their mass: oxides and/or labile to oxides compositions chosen from the group of aluminum, magnesium, zinc, silicon - 1,5÷65; oxides and/or labile to oxides compositions chosen from the group of manganese, tungsten, tin monoxide, titanium, zirconia - 0,1÷28; boron phosphate makes up the rest of the proportion.

EFFECT: enhancement of isoprene synthesis selectivity.
