    标 题:Method for the preparation of SiH-containing organopolysiloxanes
    发明人：KOERNER GOETZ; WEITEMEYER CHRISTIAN; WEWERS DIETMAR
    权利人:GOLDSCHMIDT AG TH
    摘要:A method is disclosed for the synthesis of SiH-containing organopolysiloxanes from the corresponding Si-halogen-containing organopolysiloxanes by the reaction with metal hydrides in a liquid reaction medium. The method has the following combiniation of characteristics: (a) the use of a metal hydride being LiH, NaH, KH, CaH2 or MgH2; (b) the use of ethers as reaction medium; (c) the continuous removal of the metal halide depositing on the surface of the metal hydride particles during the reaction by the action of mechanical energy or ultrasound with formation of a fresh surface. The reaction proceeds practically quantitatively and at low temperatures. It can be applied with particular advantage to industrially obtained mixtures of alpha , omega -dichloroorganopolysiloxanes.

    摘要:Improved magnesium diboride superconducting materials and methods of synthesis are disclosed. Embodiments of the superconducting material comprise at least two starting materials capable of forming MgB 2 and at least one dopant compound comprising silicon, carbon, hydrogen and oxygen. The starting materials and the at least one dopant compound are heated and mixed at an atomic level to produce a silicon-doped MgB 2 superconducting material. Examples of the dopant compound include silicone oil, Triacetoxy(methyl)silane ( 2 ), 1,7-Dichloro-octamethyltetrasiloxane ( 2 ) and Tetramethyl orthosilicate ( 6 ).
