Patent ID: 7923572

Claim:
A method for producing ketimine structure-containing alkoxysilane comprising; reacting an amino-functional alkoxysilane represented by general formula (1) (wherein R 1 represents C 1-6 monovalent hydrocarbyl, R 2 represents C 1-4 alkyl, R 3 represents C 1-10 divalent hydrocarbyl or a divalent organic group represented by —R 4 —NH—R 5 — (wherein R 4 and R 5 represent C 1-10 divalent hydrocarbyl), and n is 1, 2, or 3) with a monocarbonyl compound represented by general formula (2) (wherein R 6 and R 7 represent the hydrogen atom or C 1-10 monovalent hydrocarbyl, but do not simultaneously represent the hydrogen atom) by heating and azeotropically distilling off the produced water along with the monocarbonyl compound to yield ketimine structure-containing alkoxysilane represented by general formula (3) (wherein R 1 , R 2 , R 3 , R 6 , R 7 , and n are defined as above), characterized by introducing additional monocarbonyl compound at the time of the azeotropic distillation of the produced water along with the monocarbonyl compound of formula (2).
