The processes of amoxidau00c7u00c3o of saturated and unsaturated hydrocarbons or a mixture of saturated and unsaturated hydrocarbons

摘要

The present invention relates to the method for ammoxidation of the mixture of a kind of saturated hydrocarbons that is used for making unsaturated nitrile or unsaturated hydrocarbons or saturated hydrocarbons and unsaturated hydrocarbons, described method is included under the existence of carbon monoxide-olefin polymeric described saturated hydrocarbons or unsaturated hydrocarbons or saturated hydrocarbons is contacted with oxygen-containing gas with ammonia with the mixture of unsaturated hydrocarbons, described carbon monoxide-olefin polymeric comprises molybdenum, vanadium, antimony, niobium, tellurium, be selected from titanium, tin, germanium, zirconium, at least a element in the hafnium and be selected from lanthanum, cerium, praseodymium, neodymium, samarium, europium, gadolinium, dysprosium, holmium, erbium, thulium, at least a lanthanide series in ytterbium and the lutetium.This class catalyst is characterised in that the tellurium of utmost point low content in the composition.This class carbon monoxide-olefin polymeric is effective for the gas phase conversion (by ammoxidation) of propane to acrylonitrile and iso-butane to methacrylonitrile.
