| titleOfInvention | Method of unsaturated nitrile production |
| abstract | FIELD: chemistry.SUBSTANCE: invention relates to method of unsaturated nitrile production by reaction of propane ammoxidation in steam phase with application of fluidised bed reactor in presence of complex oxide catalyst, which contains Mo, V and Nb. Method contains stage of addition of tungsten compound into fluidised bed reactor during catalytic reaction of ammoxidation in steam phase with regulation of molar ratio (ratio W/Mo) of tungsten, contained in tungsten compound, to molybdenum, contained in complex oxide catalyst, present in fluidised bed reactor, in such a way that molar ratio is in range from 0.0001 to 0.1. Complex oxide catalyst contains complex oxide with composition, presented by formula MoVNbAXZO, in which component "A" stands for, at least, one or several elements, selected from Te and Sb; component X stands for, at least, one or several elements, selected from W, Bi and Mn; component Z stands for, at least, one or several elements, selected from La, Ce, Pr, Yb, Y, Sc, Sr and Ba; each of indices a, b, c, d, e and n stands for atomic ratio of respective element counted per Mo atom; "a" is in range 0.01 ? a ? 1; "b" is in range 0.01 ? b ? 1; "c" is in range 0.01 ? c ? 1; "d" is in range 0 ? d ? l; "e" is in range 0 ? e ? l; "n" stands for number, determined by valances of component elements.EFFECT: claimed method makes it possible to produce unsaturated nitrile by catalytic propane ammoxidation with higher selectivity without application of such stages, as soaking and drying.3 cl, 2 tbl, 16 ex |
