摘要：
A process for the ammoxidation of a saturated or unsaturated or mixture of saturated and unsaturated hydrocarbon to produce an unsaturated nitrile, said process comprising contacting the saturated or unsaturated or mixture of saturated and unsaturated hydrocarbon with ammonia and an oxygen-containing gas in the presence of a catalyst composition comprising molybdenum, vanadium, antimony, niobium, tellurium, optionally at least one element select from the group consisting of titanium, tin, germanium, zirconium, hafnium, and optionally at least one lanthanide selected from the group consisting of lanthanum, cerium, praseodymium, neodymium, samarium, europium, gadolinium, dysprosium, holmium, erbium, thulium, ytterbium and lutetium. Such catalysts are characterized by very low levels of tellurium in the composition. Such catalyst compositions are effective for the gas-phase conversion of propane to acrylonitrile and isobutane to methacrylonitrile (via ammoxidation).
摘要（中）：
饱和或不饱和或饱和和不饱和烃的混合物的氨氧化以产生不饱和腈的方法，所述方法包括使饱和或不饱和烃或饱和和不饱和烃的混合物与氨和含氧气体在 包含钼，钒，锑，铌，碲，任选地至少一种选自钛，锡，锗，锆，铪和任选的至少一种镧系元素的催化剂组合物，所述镧系元素选自镧，铈 镨，钕，钐，铕，钆，镝，钬，铒，ium，镱，镥等。 这种催化剂的特征在于组合物中碲含量非常低。 这种催化剂组合物可有效地将丙烷气相转化为丙烯腈和异丁烷至甲基丙烯腈（通过氨氧化）。
