Some organosilicon derivatives of the amides of acetic, maleic, phthalic, and succinic acids were synthesized by the reaction of γ-aminopropyltriethoxysilane with the anhydrides of these acids, and their physicochemical characteristics were determined.
The synthesized organosilicon derivatives of the amides of dibasic acids are converted to imides, while the water that is liberated here hydrolyzes the existing alkoxy group, as a result of which polymeric products are formed.
A study of the kinetics of the change in the acid number when heated discloses that the reaction is first order and that the main process, leading to a decrease in the acid number, is the intramolecular closure of the ring with the formation of the imide.
