The present invention relates to Melamine based Mannich compounds of the general formulae (1 )-(12) and a process for synthesizing melamine based Mannich-products products comprising the steps of a) reacting at least one substituted melamine with at least one aldehyde, in particular formaldehyde, under basic conditions to form at least one OH-containing compound, b) reacting the at least one OH-containing compound in the presence of a catalysts to form at least one mannich-base, d ) reacting the at least one mannich-base with at least one enol-forming carbonyl compound, or c2) reacting the at least one mannich-base with at least one aromatic compound, and d) working up the reaction mixture. The invention relates further to pre-condensates obtainable from these products.
本发明涉及通式(1)-(12)的基于三聚氰胺的Mannich化合物以及一种合成基于三聚氰胺的Mannich产物的方法,该方法包括以下步骤:a)在碱性条件下将至少一种取代三聚氰胺与至少一种醛反应,特别是甲醛,形成至少一种含有羟基的化合物;b)在催化剂的存在下将至少一种含有羟基的化合物与至少一种Mannich碱反应;c)将至少一种Mannich碱与至少一种生成烯醇的羰基化合物反应,或c2)将至少一种Mannich碱与至少一种芳香化合物反应;d)处理反应混合物。该发明还涉及从这些产物中获得的预缩聚物。
