Microwave assisting solid phase organic reaction monitored by FTIR

Microwave assisting the addition reaction of Wang resin bound secondary ami ne 1 and isocyanate was carried out for the first time. The reaction time c ourse was determined by analyzing FTIR spectra obtained using the improved KBr pellet method by grinding down the resin beads prior to recording. The results showed that the reaction assisted by microwave was accomplished onl y in 12 min, while the reaction without microwave was completed in 210 min.
