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, c1) 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.
本发明涉及一般式(1)-(12)的基于
三聚氰胺的曼尼希化合物,以及合成基于
三聚氰胺的曼尼希产物的方法,包括以下步骤:a)在碱性条件下反应至少一种取代
三聚氰胺和至少一种醛,特别是
甲醛,形成至少一种含有羟基的化合物,b)在催化剂存在下反应至少一种含有羟基的化合物,形成至少一种曼尼希碱,c1)将至少一种曼尼希碱与至少一种形成烯醇的羰基化合物反应,或c2)将至少一种曼尼希碱与至少一种芳香化合物反应,d)处理反应混合物。本发明还涉及从这些产物获得的预缩聚物。
