Studies on Addition Reaction of Melamine and Formaldehyde

Abstract

Abstract: The addition reaction between melamine and formaldehyde involves the conversion of melamine into nine different methylol melamines.The reaction mechanism of the complex system can be summarized in a simple reaction model as below:(这里有图片19890824-878-1.gif)The rate equations of above reactions are evaluated by using Runge-Kutta method, and the rate constants are determined by means of fitting them to reaction species concentrations at various times.The molecular distribution formula of methylol derivatives of polyamine, which we developed previously, is used to form simultaneous equations with reaction rate equations and the contents of various meth-ylol-melamine are calculated.The results are good in agreement with the experiment data.

Key words: Amino resins, Melamine, Reaction kinetics, Substitution effect
