  • Patent number: 7652164
    Abstract: The Direct Synthesis of trialkoxysilane is carried out by conducting the Direct Synthesis reaction of silicon and alcohol, optionally in solvent, in the presence of a catalytically effective amount of Direct Synthesis catalyst and an effective catalyst-promoting amount of Direct Synthesis catalyst promoter, said promoter being an organic or inorganic compound possessing at least one phosphorus-oxygen bond.

  • Patent number: 6372874
    Abstract: This invention disclosure describes an improved process for the preparation of siloxane-oxyalkylene copolymers via hydrosilation of unsaturated polyethers with organohydrogensiloxanes in the presence of hydroxyl, carbonyl, or ether-functional amines as buffer-catalyst modifiers for noble metal hydrosilation catalysts. The common side reactions such as dehydrocondensation and acetal formation are significantly reduced or eliminated, by the use of these amines, without reduction in hydrosilation rates.

  • Patent number: 5986122
    Abstract: This Invention discloses the use of ascorbic and citric acid, their salts, ethers, acid esters and mixtures thereof in a method for the prevention of peroxide formation, and/or for decomposing peroxides already formed in polyethers. Hereby, the polyethers are made reactive to hydrosilylation by silanes and hydrosiloxanes. When the polyether treatment is done with mixtures of ascorbic acid and sodium ascorbate and allyl polyethers, the hydrosilylation product contains reduced levels of propanal. The copolymers prepared using the treated polyethers are efficient stabilizers of flexible polyurethane foams and rigid polyurethane and polyisocyanurate foams.

    Assignee: Witco Corporation
    Inventors: Kenrick M. Lewis, Rudolph A. Cameron
  • Patent number: 5648444
    Abstract: The present invention encompasses manufacturing polysiloxane polyether copolymers using esters without any hydroxyl groups thereon, organohydrogen silanes and unsaturated polyoxyalkylene polyethers. Said esters are of low volatility and high boiling point and have at least eight carbons. The process yields clear copolymer solutions and do not need to have the ester solvent stripped. Also taught are novel compositions incorporating the ester solvent to make the copolymer and the copolymer and the ester solvent.
