Description
(a)第一の反応工程で、メラミンをホルムアルデヒド成分により1:6〜1:15のモル比でメチロール化し、
(b)第二の反応工程で、工程(a)から得られたヒドロキシメチル化中間生成物を、C1〜C20−アルコール、有利にはC1〜C6−アルコール、および特に有利にはC1〜C4−アルコールの存在下に4.5未満のpH値でエーテル化し、
(c)第三の反応工程で、工程(b)からの反応混合物を、無機塩基の添加により9.5を上回るpH値に調整し、かつ揮発性成分、特にメタノールを、少なくとも1の蒸留工程により除去し、
(d)反応工程(b)および(c)を少なくとも1回繰り返す
ことを特徴とする、エーテル化メラミン−ホルムアルデヒド縮合物の製造方法により解決される。
Xは、メラミンのモルに相応し、
Yは、ホルムアルデヒドのモルに相応し、
Zは、メタノールのモルに相応する。
反応容器中に、40%のホルムアルデヒド水溶液375gを装入し、25%水溶液の形のNaOHによりpH値を9に調整する。メラミン70gを添加した後に、反応混合物を70℃に加熱し、かつ50℃の時点から40分間攪拌する。得られるヒドロキシメチル化中間生成物を引き続き、メタノール167gで希釈し、30%のHNO3水溶液3.2mlを用いてpH値を3に調整し、かつ60℃で30分間エーテル化する。25%NO水酸化ナトリウム溶液を2.8ml添加することにより10を上回るpH値を調整し、かつエーテル化反応を終了する。過剰のメタノールを真空下に80ミリバールの圧力および温度90℃で留去する。
1/4/4 1/5/4 1/6/4 1/5/5 1/6/5 1/6/6 1/7/6 2/X/X (モル/モル/モル)
1.7 7.4 11.9 3.9 11.5 6.4 1.8 7.1 (面積%)
置換は依然として完全ではなく、生成物の50%が把握されるのみであり、その一方で、残分は分類できないことが明らかである。
1/4/4 1/5/4 1/6/4 1/5/5 1/6/5 1/6/6 1/7/6 2/X/X (モル/モル/モル)
0.3 1.3 1.9 5 13.3 18.1 5.2 46.5 (面積%)
引き続き、生成物を再度、メタノール267gで希釈し、30%のHNO3水溶液1.2mlによりpH値を3に調整する。縮合は、温度60℃で12分間行う。引き続き該溶液を25%のNaOH水溶液0.9mlでアルカリ性に調整し、かつ過剰のメタノールを真空下に120ミリバールの圧力および温度90℃で留去する。
1/4/4 1/5/4 1/6/4 1/5/5 1/6/5 1/6/6 1/7/6 2/X/X (モル/モル/モル)
0.4 1.7 0.9 0.6 9 31.9 8 28.2 (面積%)
この例により、完全にエーテル化された生成物(1/4/4、1/5/5、1/6/6)の割合が段階的に増加し、その際、同時に反応混合物の粘度が75000mPasから6400mPasに低下することが明らかである。
