Catalytic Effect of Chemically Modified Metal Alkoxides on Hydrolysis and Condensation Reactions of Methyl- and Phenyl-Ethoxysilanes
2003
Journal of the Ceramic Society of Japan
The catalytic eect of chemically modied metal alkoxides on the hydrolysis and condensation reactions of methylethoxysilanes and phenylethoxysilanes was investigated by 29 Si nuclear magnetic resonance spec troscopy and gel permeation chromatography. Metal alkoxides such as Al(OsecC 4 H 9 ) 3 , Ti(OisoC 3 H 7 ) 4 and Nb(OC 2 H 5 ) 5 modied with ethyl acetoacetate accelerated not only the condensation reactions but also the hydrolysis reactions of methyl and phenylalkoxysilanes. The catalytic
