HCID 15390519Diethyl N-[3-(trimethoxysilyl)propyl]-L-aspartate

Procedure

179.0 g (1.0 mol) of 3-aminopropyl-trimethoxysilane and 172.0 g (1.0 mol) of maleic acid diethyl ester were reacted by the same procedure used Example 1. A clear, colorless product having a viscosity of about 30 mPa.s (23° C.) was obtained. The amine equivalent weight determined by base titration was about 359 g (theory: 351 g).
