  • Publication number: 20100041546
    Abstract: An oxidation catalyst is prepared by pyrolyzing a source of iron and a source of nitrogen on a carbon support. Preferably, a noble metal is deposited over the modified support which comprises iron and nitrogen bound to the carbon support. The catalyst is effective for oxidation reactions such as the oxidative cleavage of tertiary amines to produce secondary amines, especially the oxidation of N-(phosphonomethyl)iminodiacetic acid to N-(phosphonomethyl)-glycine.

  • Patent number: 6476256
    Abstract: A process for the preparation of an oxyacid of phosphorus comprising contacting elemental phosphorus with water in the presence of a catalyst effective to promote oxidation of phosphorus by reaction with water. The use of a noble metal catalyst such as Pd under moderate agitation and low severity conditions is effective for the preparation of P(III) oxyacid in high selectivity. Other suitable catalysts may comprise, for example, other Group VIII metals (particularly other platinum metals); oxides, salts, phosphides, and/or coordination compounds of Group VIII metals; Group IB metals; and/or oxides, salts, phosphides, and/or coordination is compounds of Group IB metals. Various apparatus and process schemes for the preparation of phosphoric and phosphorous acid are also disclosed.

  • Patent number: 5382629
    Abstract: Vulcanizable rubber compositions are disclosed which contain co-activator of vulcanization which is a polymeric amine, that is, a hydrocarbon polymer with pendent alkyl amine groups. The co-activators impart increased rates of vulcanization with little decrease in scorch delay and very little increase in the modulus of the cured compositions. No increase in heat build-up or decrease in flex-fatigue life is shown. Typical polymers forming the backbone of the co-activators include EPDM rubber and polymers from butadiene or isoprene, with optional co-monomers.
