An accurate analysis method of reaction critical state by stoichiometric window function

Abstract

The tangent method, which is an international standard for analysis of critical state of reaction, is a mathematical method and containing no physical connotations of critical characteristics. Critical moments of reactions were analyzed in the present work and their corresponding temperatures were determined using analysis theory of stoichiometric window function method and stoichiometric relation of reaction based on reaction process λ, which is a characteristic parameter of reactions. The method is based on the qualitative and quantitative mass spectrometric analysis of gaseous substance of the reaction process, the molar yield of the material is used as the basis for calculation. The theoretical analysis by stoichiometric window function method is consistent with experimental results.
