  • Patent number: 8680211
    Abstract: A process for preparing a hybrid polyester-polyether polyol comprises contacting a carboxyl group-containing component and an epoxide, optionally in the presence of one or more of a double metal cyanide catalyst, a superacid catalyst, a metal salt of a superacid catalyst and/or a tertiary amine catalyst, under conditions such that a hybrid polyester-polyether polyol is formed. The hybrid polyester-polyether polyol offers the advantages of both ester and ether functionalities when used in a polyurethane formulation, thus enhancing physical properties. The process results in products having narrow polydispersity, a low acid number and unsaturation, and reduced byproduct formation, particularly when the double metal cyanide catalyst is employed.

  • Patent number: 8674149
    Abstract: 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.

  • Patent number: 8664453
    Abstract: A process and apparatus for recovering dichlorohydrins from a mixture comprising dichlorohydrins, one or more compounds selected from esters of dichlorohydrins, monochlorohydrins and/or esters thereof, and multihydroxylated-aliphatic hydrocarbon compounds and/or esters thereof, and optionally one or more substances comprising water, chlorinating agents, catalysts and/or esters of catalysts is disclosed. The mixture is distilled or fractionated to separate a lower boiling fraction comprising dichlorohydrin(s) from the mixture to form a higher boiling fraction comprising the residue of the distillation or fractionation. The higher boiling fraction is stripped to recover remaining dichlorohydrins. Advantages include more efficient recovery of dichlorohydrins for a given distillation column, less waste due to avoiding the conditions conducive to the formation of heavy byproducts, and reduced capital investment in recovery equipment.
