  • Patent number: 5716590
    Abstract: Catalytic dehalogenation (or hydrodehalogenation) of halogen-containing compounds of elements of group IV of the periodic table in the presence of hydrogen is carried out using a finely-dispersed catalytically active material which comprises silicon and at least one transition metal, and which is characterized by high catalytic activity and stability. This process can be used, for example, for synthesizing compounds or alternatively for decomposing halogen-containing compounds, for instance in waste-water or waste-gas purification processes. It is also suitable for dehalogenation (hydrodehalogenation) of halogen-containing silane compounds, for instance of silicon tetrachloride or alkyl trichlorosilane compounds, and the original purity of the silanes used as starting materials is retained by the products. Tetrachlorosilane, for example, can be converted into trichlorosilane.

  • Patent number: 4785066
    Abstract: Certain liquid polydiorganosiloxanes wherein each molecule contains at least one sequence of 2 or more vinyl radicals bonded to non-terminal silicon atoms extend the working time at 25.degree. C. of organosiloxane compositions that cure by a platinum catalyzed hydrosilation reaction without adversely affecting the cure rate of the composition at temperatures of about 100.degree. C. and above. The polydiorganosiloxane is prepared by the acid-catalyzed polymerization of the corresponding cyclic polydiorganosiloxanes in the presence of a chain-terminating organosilicon reactant.

  • Patent number: 4570010
    Abstract: Disclosed is an improved process for the production of organic polyisocyanate-based molded polymers prepared from at least one organic polyisocyanate and at least one polyol wherein there is employed an internal mold release agent comprising an amino-polysiloxane having at least one group of the formulaRNH-alkylene--O--bonded to a silicon atom of a polysiloxane, wherein R is selected from the group consisting of hydrogen, lower-alkyl, cycloalkyl, and ECHR"CHR'-- wherein E is an electron withdrawing group and R' and R" are independently selected from the group consisting of hydrogen and methyl.The molding process can be repeated many times before the mold surfaces must be cleaned or treated with release agent. The ease of release of the molded polyurethanes makes the process particularly suitable for RIM production methods.

  • Patent number: RE38947
    Abstract: A chiral catalyst is disclosed together with methods of using it for enantioselective syntheses. The chiral catalyst includes a nucleus with two metal atoms that has four bridging ligands oriented radially to the axis of the nucleus. Each of these ligands includes a two complexing atoms each complexed to one of the metal atoms. At least one of the bridging ligands includes a chiral center which is bonded to one of the complexing atoms. Preferably, all four of the bridging ligands include a chiral center bonded to one of the complexing atoms. The catalyst of the invention has been found to be useful in catalyzing carbenoid transformation reactions such as cyclopropanation.
