METAL OXIDE-BASED CATALYST FOR OXIDATIVE AMMONOLYSIS OF ETHYLENICALLY UNSATURATED COMPOUNDS, METHOD OF PREPARATION THEREOF, AND METHOD OF OXIDATIVE AMMONOLYSIS OF ETHYLENICALLY UNSATURATED COMPOUNDS Russian patent published in 1999 - IPC

FIELD: catalysts for organic syntheses. SUBSTANCE: composition of catalyst defined by general formula I: [A_aB_bO_x]_p[C_cD_dFe_eMe_fE_iF_jO_y]_q (I) wherein A is bismuth, tellurium, antimony, tin, and/or copper; B molybdenum and/or tungsten; C alkali metal, thallium, and/or samarium; a=0.01-8, b= 0.1-30, c up to 4, and x and y are numbers determined by valence and occurrence of non-oxygen elements is distinguished by that symbol D in formula I indicates alkali-earth metal, nickel, copper, cobalt, manganese, zinc, tin, cerium, chromium, cadmium, molybdenum, bismuth, and/or mercury; Me is cobalt; E phosphorus, arsenic, boron, and/or antimony; F rare-earth metal, vanadium, and/or uranium; d up to 20, e up to 20, f up to 20, i up to 5, j up to 15, p/q=0.001-0.099. Preparation procedure: (i) formation of key phase with formula A_aB_bO_x; (ii) formation of cophase with formula C_cD_dFe_eMe_fE_iF_jO_y or water-soluble salts of cophase elements, or mixture of at least one of those water- soluble salts with at least one calcined phase of one of elements not forming mentioned water-soluble salt; (iii) mixing key phase with cophase; (iv) if necessary, drying mixture prepared according to item (iii), followed by calcination and, if necessary, formation of catalyst paste by known techniques, average particle size of at least one catalyst constituent chemically differing from the other constituent being varying from 10 nm to 1 mcm. EFFECT: increased catalyst activity. 4 cl, 1 tbl, 2 ex
