A process for the vapor phase ammoxidation of alkanes and olefins with a catalyst of the general empirical formula:
VSb
a
M
b
Q
c
O
x
wherein M is at least one element selected from magnesium, aluminum, zirconium, silicon, hafnium, titanium and niobium, Q is at least one element selected from rhenium, tungsten, molybdenum, tantalum, manganese, phosphorus, cerium, tin, boron, scandium, bismuth, gallium, indium, iron, chromium, lanthanum, yttrium, zinc, cobalt, nickel, cadmium, copper, strontium, barium, calcium, silver, potassium, sodium and cesium, a is 0.5 to 20, b is 2 to 50, c is 0 to 10 and x is determined by the valence requirements of the elements present. The process has a co-feed of gaseous carbon dioxide with an alkane (paraffin) and/or alkene, ammonia and an oxygen-containing gas which react in the presence of the catalyst to form a nitrile and by-products.
一种用具有一般经验公式:VSbaMbQcOx的催化剂对烷烃和烯烃进行蒸汽相氨氧化的工艺,其中M至少是选择自镁、铝、锆、硅、铪、钛和铌的一种元素,Q至少是选择自铼、钨、钼、钽、锰、磷、铈、锡、硼、钪、铋、镓、铟、铁、铬、镧、钇、锌、钴、镍、镉、铜、锶、钡、钙、银、钾、钠和铯的一种元素,a为0.5至20,b为2至50,c为0至10,x由存在的元素的价需求确定。该工艺在存在催化剂的情况下,通过对气态二氧化碳与烷烃(烷烃)和/或烯烃、氨和含氧气体的共进料进行反应,形成一种腈和副产物。
