Abstract

1286077 Tertiary amino siloxanes DOW CORNING Ltd 31 Oct 1969 [1 Nov 1968 26 June 1969] 51839/68 and 32224/69 Headings C3S and C3T A tertiary aminoalkylsiloxane is obtained by reaction in the presence of a platinum catalyst of (1) an organosiloxane containing at least one silicon-bonded hydrogen atom and (2) an amine QNR<SP>1</SP>R<SP>11</SP> in which Q is a C 3-12 monovalent unsaturated hydrocarbon radical and R<SP>1</SP> and R<SP>11</SP> are each a C 1-4 alkyl or alkenyl radical, or an aryl, aralkyl, alkaryl or alkoxyalkyl radical. The siloxane (1) is preferably linear and contains units RHSiO or R 2 HSiO 1/2 to provide Si-H, R being an organic group, preferably methyl or phenyl. The catalyst may be any "platinum group" metal or compound. The products may be converted into amine oxides. In examples H 2 PtCl 6 .6H 2 O in isopropanol is used to catalyse reactions of allyl dimethylamine, allyl diethylamine, 1 - (dimethylamino) - but- 3 - ene, 1 - (dimethylamino) - pent - 4 - ene, diallyl methylamine or triallylamine with trimethylsilyl - terminated dimethylsiloxane/ methylhydrogensiloxane copolymers or pentamethyl disiloxane or pentaphenyl disiloxane or 1-hydro-nonomethyl tetrasiloxane. The di- and tri-allyl amines give rise to di- and tri-(disiloxanylpropyl) amines.
