FIELD: chemistry.SUBSTANCE: invention relates to production of ion-exchange moulded catalysts. Described is an ion-exchange moulded catalyst for organic synthesis, which contains a mixture of copolymers with a macroporous and gel structure, a sulphonated copolymer of styrene and divinyl benzene, and a thermoplastic binding component - polypropylene, wherein the weight ratio of the gel and macroposous components is equal to (3.7-14.0):1, respectively, with respect to the dry catalyst, the amount of the binding component is equal to 20-30 wt % with respect to the dry catalyst, the starting components are taken with residual moisture content of not more than 10 wt % and fractional composition of not less than 95% of a fraction of particles with size in the range of 50-200 mcm. Described is a method of producing said catalyst.EFFECT: obtaining a catalyst in which there is no blocking of the adsorption space of the catalyst and premature evaporation of water.4 cl, 2 tbl, 12 ex |
