Abstract: The catalyst is used for production of methacrylic acid. The composition is PaMo12TlbVcCudXeYfOg (where, P is phosphorus, Mo is molybdenum, Tl is thallium, V is vanadium, Cu is copper, O is oxygen, X is at least one compound chosen among cesium and potassium, Y is at least one compund selcted from organic cyclic compounds contaning pyridine or nitrogen; a,b,c,d,e and f are the mole ratios, a=1-1.6, b=0.1-1.0, c=0.5-1.5, d=0.1-0.5, e=0.5-2.0, f=0.01-0.5, g is value to adjust atomic valence of each composition). The catalyst carrier is silica or alumina.

Abstract: This relates to prolonging the life of heteropolyacid catalyst of formula HaXbYcMdOf in acid-catalyst reaction or oxidation. The life of catalyst is prolonged by supplying at least one of 0.1-10000 ppm piridine or nitrogen contained organic cyclic compound, amine, and ammonia continuousl or periodically in gas-phase oxidation in the presence of a catalyst. In the formula, H is proton; X is alkali, alkali earth, rare earth, and one or group of cations of Fe, Cu, Ag, Tl, Pb and Bi; Y is Si,P,Ge,As; M is V,Mo,W; O is oxygen; and each of a,b,c,d is tom ratio.
Abstract translation: 这涉及在酸催化剂反应或氧化中延长式HaXbYcMdOf的杂多酸催化剂的使用寿命。 通过在催化剂存在下，在气相氧化中连续或周期性地供给0.1-10000ppm的吡啶或含氮的有机环状化合物，胺和氨中的至少一种来延长催化剂的寿命。 在该式中，H是质子; X是碱金属，碱土金属，稀土元素，以及Fe，Cu，Ag，Tl，Pb和Bi的一种或多种阳离子; Y为Si，P，Ge，As; M是V，Mo，W; O是氧; a，b，c，d分别为汤姆比。
