| Abstract: | The blocking reaction between powder of sodium bisulfite and PAPI using acetone as the solvent was studied. The change of isocyanate group concentration along with the time at different temperature was inrestigated. The reaction rate constants at different temperature were calculated, and the reaction kinetics was analyzed. |
