METHOD OF PROCESSING OF ORGANIC RAW MATERIAL AND CATALYST FOR ITS EMBODIMENT Russian patent published in 1999 - IPC

FIELD: methods and catalysts for processing of organic raw materials. SUBSTANCE: organic raw material is processed in three-section reactor. Reactor includes section of boron trifluoride source, catalytic section and section of boron trifluoride absorbent. In section of boron trifluoride source, raw material flow in contact with metal tetra fluoroborate applied t porous carrier, and in section of boron trifluoride absorbent, flow of products of catalytic reaction comes in contact with boron fluoride applied to porous carrier and capable of absorption of boron trifluoride. In so doing, periodically, as metal tetrafluoroborate becomes decomposed in section of boron triflouride source and accumulation of metal tetrafluoroborate in section of boron trifluoride absorbent, inversion of functions of these sections of reactor is effected simultaneously with inversion of direction of flows of organic raw material and products of reaction. Used in process is catalyst whose active component is in form of catalytic complex applied to porous carrier and consisting of boron trifluoride and heteropoly compound in ratio of 0.1 to 0.5, preferably, from 0.5 to 2 in amount of 0.1 to 55 wt. %, preferably, from 2 to 30 wt.%. Heteropoly compound is produced from one or several oxides of elements of groups III, IV, V, VI and from one or several salts of metals with general formula (Me)_x(XO₄)_y, where Me is metal of groups III and IV; x=1-2; y=2-3;X is sulfur or phosphorus taken in molar ratio of oxides to salts equalling 0.5 to 20, preferably, from 1.5 to 10, or from compounds forming said oxides and salts in preparation of heteropoly compounds. Composition of heteropoly compound in terms of oxides is described by empirical formula Me_kX_mO_n, where Me are elements taken from group including Ga, B, Al, Ti, Zr, Sn or their mixtures; X are elements taken from group including P, S or their mixtures; k=1-80; m=1-100 with heteropoly compound acidity determined by Hammet's scale within interval pKa from minus 5.6 to minus 12.7. EFFECT: higher yield of desired product and increased efficiency of catalyst. 24 cl, 11 tbl, 44 ex
