Abstract
A new method for the kinetic study of cyclization reaction using the chemical shrinkage was described. The kinetic parameters derived by function fit were used to predict the rate constant at a given temperature and the feasibility of this method was verified by the Kissinger method. The results indicate that the method is feasible and the order of cyclization reaction is relevant to stabilization temperature with an activation energy of 159.11 kJ/mol.
