Abstract
The present invention relates to an alkylalkoxysilane compound of a novel structure which has an ether group and an dialkylamino group in an alkyl chain of the alkylalkoxysilane and thus has remarkably improved storage stability and hydrophilicity and a method for preparing same.
Claims3
A method for preparing an alkylalkoxysilane compound, comprising:
- preparing an intermediate compound of Chemical Formula 4 by coupling an allyl halide compound of Chemical Formula 2 with an N,N-dialkylaminoalkanol of Chemical Formula 3 in the presence of a base:
- (wherein R1 and R2 is the same or different unsubstituted C1-C10 alkyl group;
- n is an integer from 0 to 5;
- and m is an integer from 0 to 3);
- and
- preparing an alkylalkoxysilane compound of Chemical Formula 1 by hydrosilylating the intermediate compound of Chemical Formula 4 with a silane compound of Chemical Formula 5:
- (wherein R1, R2, R3 and R4 is the same or different unsubstituted C1-C10 alkyl group;
- R5 is an unsubstituted C1-C10 alkyl group or an unsubstituted C1-C10 alkoxy group;
- and n is an integer from 0 to 5;
- and m is an integer from 0 to 3).
