Patent ID: 8728225

Claim:
A process for preparing a composition comprising at least one quaternary amino-functional organosilicon compound, comprising: (A) reacting component A, comprising (i) at least one haloalkyl-functional alkoxysilane of formula (I) (R 1 O) 3−x−y (R 2 ) x Si[(R 3 ) n CH 2 Hal] 1+y (I), wherein R 1 groups are the same or different and R 1 represents a hydrogen, a linear, branched, or cyclic alkyl group having 1 to 8 carbon atoms, an aryl, arylalkyl, or acyl group, R 2 groups are the same or different and R 2 represents a linear, branched, or cyclic alkyl group having 1 to 8 carbon atoms, or an aryl, arylalkyl, or acyl group, R 3 groups are the same or different and R 2 represents a linear, branched, or cyclic alkylene group having 1 to 18 carbon atoms, n is equal to 0 or 1, Hal represents chlorine or bromine, x is equal to 0, 1, or 2, y is equal to 0, 1, or 2, and (x+y) is equal to 0, 1 or 2, or (ii) a hydrolysis or condensation product of the at least one alkoxysilane of formula (I), or (iii) a mixture of the at least one alkoxysilane of formula I and at least one selected from the group consisting of a hydrolysis product and a condensation product of the at least one alkoxysilane of formula (I), with component B, comprising at least one tertiary amine selected from the group consisting of a compound of formula (IIa) and a compound of formula (IIb), (R 14 ) 2 N[CH 2 CH 2 N(R 14 )] h CH 2 CH 2 N(R 14 ) 2 (IIa), wherein R 14 in each occurrence independently represents a branched, unbranched or cyclic alkyl, aryl or alkylaryl group having 1 to 20 carbon atoms, and h is equal to 0, 1, 2, 3, 4, 5, 6 or 7, [(CH 3 )—(CH 2 ) w ] p *N(R 14 ) 3−p * (IIb), wherein w is equal to 2 to 20, and R 14 in each occurrence independently represents a branched, unbranched or cyclic alkyl, aryl or alkylaryl group having 1 to 20 carbon atoms, and p* is equal to 1 or 2, in the presence of a defined amount of water wherein the water is reacted in an amount of 0.5 to 500 mol of water per mole of silicon atoms present in the reaction mixture, and (B) removing a resulting hydrolysis alcohol at least partially from the system during the reaction.
