Abstract

Abstract: Addition reaction could take place between rosin and maleic anhydride. The rosin maleic adduct also could be bromized by liquid bromine. The molecular structures of rosin maleic adduct and its bromide were characterized by comparison with rosin and its bromide using their IR spectra. The thermal stabilities of rosin, rosin bromide, rosin maleic adduct and its bromide were studied by comprehensive thermal analyzer. The results showed that rosin and its adduct were easy to form bromides, and the thermal stabilities of bromides was decreased because of formation of weak C-Br bond.

Key words: rosin, maleic anhydride, bromide, comprehensive thermal analysis

CLC Number:
