    摘要: Oxidatively halogenate methane by placing a feedstream that comprises methane, a source of halogen, a source of oxygen and, optionally, a source of diluent gas in contact with a first catalyst (e.g. a solid super acid or a solid super base) that has greater selectivity to methyl halide and carbon monoxide than to methylene halide, trihalomethane or carbon tetrahalide. Improve overall selectivity to methyl halide by using a second catalyst that converts at least part of the feedstream to a mixture of methyl halide, methylene halide, trihalomethane, carbon tetrahalide and unreacted oxygen, and placing that mixture in contact with the first catalyst which converts at least a portion of the methylene halide, trihalomethane and carbon tetrahalide to carbon monoxide, hydrogen halide and water.

    摘要: A process of preparing a mixture of polyalkylenepolyamines and alkanolpolyamines comprising contacting a difunctional aliphatic alcohol with a primary or secondary aliphatic amine in the presence of a metal silicate catalyst wherein the metal is selected from the group consisting of Groups IIA, IIIB, and the lanthanide and actinide metals. For example, monoethanolamine reacts with diethylenetriamine in the presence of magnesium silicate to yield a mixture of higher molecular weight linear and branched polyethylenepolyamines and their corresponding alkanolpolyamines. These product mixtures are useful in the formation of specialty polyurethanes.
