1292077 Silanes DYNAMIT NOBEL AG 24 July 1970 [25 July 1969] 36118/70 Heading C3S Novel silanes of the formula (wherein R<SP>11</SP> represents an alkyl group) and other organosilicon compounds are prepared by reacting a silane of the formula H a SiR b X 4- ( a+b ), in which X represents halogen, alkoxy, or aryloxy, R reprssents halogen, alkoxy, aryloxy, alkyl, cycloalkyl or aryl, a is 1 or 2 and b is 0 or 1, with an ethylenically or acetylenically unsaturated compound in the presence of a platinum catalyst of the formula [PtR<SP>1</SP>Cl 2 ] c in which R<SP>1</SP> represents a molecule of an unsaturated ketone and c is 1 or 2. Examples describe the preparation of gamma-glycidyloxypropyltrimethoxysilane, 3 - acetyl - oxypropyl - trichlorosilane, 3 - (2<SP>1</SP> - ethylcaproyloxy) - propyltriethoxysilane, 3 - methacryloxypropyl - trichlorosilane, 3 - methacryloxypropyl - trimethoxysilane, 3 - tetrahydrofurfuryl - 2 - methyloxypropyl - triethoxysilane, 3 - tetrahydrofurfuryl - 2 - methyloxypropyl - trimethoxysilane and the conversionof the latter to the corresponding triethoxysilane derivative by reaction with ethanol. Uses.-As resin additives, in glass dressings and finishes, for treating metals, minerals, wood, textiles and paper, and as bonding agents between polymers and glass. |
