摘要
三聚氰胺 (MA)在含有HCl的水溶液中与甲醛 (FA)进行羟甲基化反应。HCl与MA以等摩尔比结合 ,在反应过程中逐渐析出 ,至反应完毕仍保留半结合量。氢离子浓度对三聚氰胺甲醛树脂 (MF)
The hydroxymethylation is taken place between melamine and formaldehyde in aqueous solution catalyzed by hydrochloric acid,The latter combines with melamine in equimolar ratio and releases gradually throughout the reaction process,but it remains half the amount in system until the end of the reaction,The hydrogen ion concentration exerts a great influence on the stability of the melamine resin solution.
