Abstract:
A method for preparing a water-soluble organic silicon compound comprisingeffecting co-hydrolysis in the presence of an organic or inorganic acid of(A) 1 to 30 parts by weight of an alkyltrialkoxysilane of the following general formula (1):R.sup.1 Si(OR.sup.2).sub.3 ( 1)wherein R.sup.1 is a hydrocarbon group having 7 to 18 carbon atoms and R.sup.2 is an alkyl group having 1 to 4 carbon atoms, or a partial hydrolyzate thereof,(B) 70 to 90 parts by weight of an alkoxy-containing siloxane of the following general formula (2):R.sup.3.sub.a (OR.sup.2).sub.b SiO.sub.(4-a-b)/2 ( 2)wherein R.sup.2 is as defined above, R.sup.3 is an alkyl group having 1 to 6 carbon atoms, letter a is a positive number of 0.75 to 1.5, b is a positive number of 0.2 to 2, and 0.95<a+b<3.4, and(C) 1 to 20 parts by weight of an amino-containing alkoxysilane of the following general formula (3):R.sup.4 R.sup.5 NR.sup.6 --SiR.sup.7.sub.n (OR.sup.2).sub.3-n( 3)wherein R.sup.2 is as defined above, R.sup.4 and R.sup.5 are independently selected from the group consisting of a hydrogen atom, alkyl and aminoalkyl groups having 1 to 15 carbon atoms, R.sup.6 is a divalent hydrocarbon group having 1 to 18 carbon atoms, R.sup.7 is an alkyl group having 1 to 4 carbon atoms, and letter n is 0 or 1.
