Open publisher page 0 citations

Abstract

The blocking reaction between Phenol and Hexa-diisocyanate with toluene as solvent has been studied.The effects of temperature on the reaction rate were investigated.The reaction rate constant at different temperature were calculated,and the kinetics of the reaction was analyzed.The results show that the reaction is a second order,and activation energy is: E_a=124.77 KJ·mol~(-1).The temperature influence the rate of the reaction obviously.
