  • Publication number: 20150105576
    Abstract: A hydrosilylation method is provided. In this hydrosilylation method, silylation of the carbon atom other than the terminal carbon atom and generation of the by-product isomer by internal migration of the double bond are suppressed without sacrificing the hydrosilylation reactivity, even if an olefin compound having tertiary amine atom which can be a catalyst poison was used. In the hydrosilylation, an olefin compound having carbon-carbon unsaturated bond, and a compound having hydrogensilyl group are reacted in the presence of an acid amide compound, a nitrile compound and an aromatic hydroxyl compound, or an organoamine salt compound, by using catalytic action of platinum and/or its complex compound.

  • Publication number: 20130029311
    Abstract: Siloxane-based coatings for providing writable-erasable surfaces are provided. The coatings have many desirable characteristics and advantages over known coatings for writable-erasable surfaces. For example, the coatings cure rapidly under ambient conditions, have low VOC emissions upon curing, and have reduced tendency to form ghost images, even after prolonged normal use.

  • Publication number: 20120202893
    Abstract: To provide a method for manufacturing a purified product of an alkyl-modified polydimethylsiloxane that is practically odorless and compatible with other cosmetic raw materials. The manufacturing method comprises the steps of: [A] synthesizing an alkyl-modified polydimethylsiloxane by subjecting a hydrosilyl-containing polydimethylsiloxane and an C2-C30 ?-olefin to a hydrosilation reaction, and [B] subjecting the crude alkyl-modified polydimethylsiloxane obtained in Step [A] to a treatment of rendering it odorless by a hydrogenation reaction in the presence of a hydrogenation catalyst in an organic solvent (c) that is essentially free of active hydrogen atoms and has a boiling point equal to or greater than 70° C.

  • Publication number: 20120192762
    Abstract: Fine mesoporous silica particles are provided by which not only the functions of low reflectance (Low-n), low dielectric constant (Low-k) and low thermal conductivity but also improved strength of a molded article are achieved. The fine mesoporous silica particles are manufactured by a process including a surfactant composite fine silica particle preparation step and a mesoporous particle formation step. In the silica fine particle preparation step, a surfactant, water, an alkali and a hydrophobic part-containing additive including a hydrophobic part for increasing the volume of micelles are mixed with a silica source to thereby prepare surfactant composite fine silica particles. In the mesoporous particle formation step, the mixture is mixed with an acid and an organosilicon compound to thereby remove the surfactant and hydrophobic part-containing additive from the surfactant composite fine silica particles and provide the surface of each silica fine particle with an organic functional group.

  • Publication number: 20120149901
    Abstract: A hydrosilylation method is provided. In this hydrosilylation method, silylation of the carbon atom other than the terminal carbon atom and generation of the by-product isomer by internal migration of the double bond are suppressed without sacrificing the hydrosilylation reactivity, even if an olefin compound having tertiary amine atom which can be a catalyst poison was used. In the hydrosilylation, an olefin compound having carbon-carbon unsaturated bond, and a compound having hydrogensilyl group are reacted in the presence of an acid amide compound, a nitrile compound and an aromatic hydroxyl compound, or an organoamine salt compound, by using catalytic action of platinum and/or its complex compound.
