Synthesis of Complex Oligoesters Based on Adipic Acid, Ethanediol and Butanediol-1,4 with Specified Characteristics

Abstract:

Aliphatic linear oligoesters with terminal hydroxyl groups and given molecular weight characteristics, hydroxyl and acid numbers were synthesized by esterification of adipic acid, ethylene glycol and butanediol-1,4. It was found that the main properties of complex oligoesters largely depend on the ratio of the starting reagents. The kinetic regularities of the process of esterification of adipic acid, ethylene glycol and butanediol-1,4 have been studied and determined. It was found that the duration of the vacuum stage of esterification in the presence of organomodified montmorillonite is noticeably shorter than when using a commercial catalyst.
