    摘要： Olefins such as propylene and isobutylene are converted to the corresponding unsaturated nitriles, acrylonitrile, and methacrylonitrile, respectively, by reacting a mixture of the olefin, ammonia, and molecular oxygen-containing gas in the presence of a catalyst containing the oxides of molybdenum, bismuth, iron, cobalt, nickel, and chromium, and either phosphorus or antimony or mixtures thereof, and an alkali metal or mixture thereof, and optionally one element selected from the group of an alkaline earth metal, a rare earth metal, niobium, thallium, arsenic, magnesium, zinc, cadmium, vanadium, boron, calcium, tin, germanium, manganese, tungsten, tellurium, or mixtures thereof.

    摘要： Coated catalysts having an inert support material with an outer surface and a coating of active catalyst containing molybdenum, phosphorus, arsenic, copper and oxygen have been found to be especially effective catalysts for the production of unsaturated acids from the corresponding unsaturated aldehydes, for example, methacrolein is oxidized to methacrylic acid using these catalysts. The catalysts give a very low exotherm, very high single pass yields of the desired acid and reduce the undesirable byproducts.
