    摘要： Included is the oxydehydrogenation of saturated dinitriles, for example, succinonitrile, to prepare unsaturated dinitriles, for example, fumaronitrile and maleonitrile. Succinonitrile can be oxydehydrogenated by passing it in a vapor phase over a calcined calcium nickel phosphate catalyst, and the selectivity to fumaronitrile can be varied by the presence of water vapor in the vapor phase feed mixture.

    摘要： Metal cyanide catalysts are prepared by first forming a precipitate using no more than a stoichiometric amount of a water-soluble metal salt of the form MxAy, based on the amount of metal cyanide compound that is used. The precipitate is then treated with an additional quantity of a metal salt of the form M3xAy, in which M3 may be the same as or different than M. The catalyst is treated with a complexing agent, either during the precipitation step or during the subsequent treatment with the M3xAy salt.

    摘要： This invention, in one respect, is a process for producing allylic chlorides which comprises contacting a feedstream containing an olefin in the gas phase with a chlorination composition under conditions effective to produce an allylic chlorine and wherein the mole ratio of oxygen to olefin is from 0 to about 1:20 in the feedstream. The chlorination composition contains supported palladium chloride, platinum chloride, or palladium chloride and a chloride of a Group 1 alkali metal selected from the group consisting of lithium, sodium, and potassium; a Group 2 alkaline earth metal; a Group 9 metal; nickel; and a Group 12 metal. The chlorination composition can be regenerated by contacting the chlorination composition with chlorine in a cyclic reaction scheme.In another respect, this invention is a composition consisting essentially of (A) palladium chloride, (B) a chloride of a metal selected from the group consisting of lithium, sodium, potassium, calcium, strontium, barium, nickel, and mixtures thereof, and (C) a support, wherein the weight percent of (A) and (B) in the composition is from about 0.1 to about 45.
