Method for the preparation of SiH-containing organopolysiloxanes |
| abstract |
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. |
