Abstract
Official abstract text for this publication.
Novel amino acid-modified silane compounds having a weakly acidic amino group and a weakly basic carboxyl group are useful as a surface treating agent or textile treating agent.
First claim
Opening claim text (preview).
The invention claimed is: 1. An amino acid-modified silane compound having the general formula (1): wherein R 1 , R 4 and R 5 each are hydrogen, R 2 and R 3 each are a substituted or unsubstituted, C 1 -C 20 monovalent hydrocarbon group, R 6 is hydrogen or carboxyl group, a is 1, b is 3, and n is 0, 1 or 2. 2. The silane compound of claim 1 , which is N-(3-trimethoxysilylpropyl)-β-alanine, N-(3-methyldimethoxysilylpropyl)-β-alanine, N-(3-triethoxysilylpropyl)-β-alanine, N-(3-methyldiethoxysilylpropyl)-β-alanine, N-(3-trimethoxysilylpropyl)aspartic acid, N-(3-methyldimethoxysilylpropyl)aspartic acid, N-(3-triethoxysilylpropyl)aspartic acid, or N-(3-methyldiethoxysilylpropyl)aspartic acid. 3. A method for preparing the amino acid-modified silane compound of claim 1 , comprising de-triorganosilylation reaction of a silyl-protected, amino acid-modified silane compound having the general formula (2): wherein R 1′ is R 1 or a triorganosilyl group of R 10 R 11 R 12 Si—, R 1 , R 4 and R 5 each are hydrogen, R 2 and R 3 each are a substituted or unsubstituted, C 1 -C 20 monovalent hydrocarbon group, R 6′ is hydrogen or a silyl-protected carboxyl group, R 7 , R 8 , R 9 , R 10 , R 11 and R 12 each are a substituted or unsubstituted, C 1 -C 20 monovalent hydrocarbon group, a is 1, b is 3, and n is 0, 1 or 2.
