Abstract:
Fourier transform infrared spectroscopy（FT-IR） was used to monitor the esterification between maleic anhydride and polyethylene glycol （PEG）. The kinetics of the esterification was semi-quantitatively made according to the area change of characteristic IR absorption peaks which the esterification products showed in different reaction time. The influence of catalyst and reaction temperature on the esterification kinectics was investigated and the best reaction conditions for the monoester product were found.[著者文摘]
Key words:
FT-IR; maleic anhydride; PEG; esterification
