Description
転化度=(NCO開始-NCO終了)/NCO開始×100
イソシアネート基の含有量は、例えばDIN EN ISO 11 909:2007-05に準拠した滴定によって決定することができる。
すべてのパーセンテージ及びppmデータは、特に明記しない限り、重量に基づく。
13.1g(0.15mol)のピペリジン及び20g(0.18mol)の50%水酸化カリウム水溶液の100°Cに予熱した混合物に、内部温度が110°Cを超えないように20g(0.16mol)の1,4-ジクロロブタンを滴下した。添加が完了した後、混合物を100°Cでさらに4時間撹拌し、次いで室温まで冷却した。
1055gのHDIを最初に投入し、外部循環により60°Cの温度に維持され、撹拌機、不活性ガスユニット(窒素/真空)に接続された還流冷却器、及び温度計を装備した平地接合部を備えたジャケット付き容器内で、真空(<1mbar)下で1時間撹拌することにより、溶存ガスを除去した。窒素で通気した後、表1に指定された触媒の量を、反応の発熱が2~3°Cを超えないように少しずつ計量した。NCO含有量が、
a)約45+/-0.5%
b)約30+/-1%
に低下した後、
触媒に2-PrOH中等モル量のドデシルベンゼンスルホン酸70%を添加し、反応温度でさらに30分間撹拌することにより、触媒を失活させた後、混合物を後処理した。
例2に記載された装置において、1000gのPDIが最初に投入され、そのうち6-クロロ-3,4-ジヒドロピリジン-1(2H)-カルボニルクロリドの含有量は、開始時に指定された純物質の添加により190ppmに調整され、そこに記載された手順と同様に処理したが、不活性化剤のモル量を、NCO含有量が、
a)約50+/-0.5%
b)約35+/-1%
に低下した後に使用した触媒の量と同等に計量したという点が異なる。
これは、例3bシリーズと同様に実施したが、実験4-1~4-4における反応を80~85°Cで実施し、後の2つの実験を100~105°Cで実施し、1000gのPDIを使用し、そのうち、6-クロロ-3,4-ジヒドロピリジン-1(2H)-カルボニルクロリドの含有量を開始時に指定された純物質の添加により540ppmに調整したという点で異なる。結果は、表3で見ることができる。
これは、例4シリーズと同様に実施したが、反応を70~73°Cで実施し、触媒を2-エチルヘキサノール中約1%の溶液として使用し、1000gのPDIを使用し、そのうちHC/AC含有量が、検出限界(<5ppm)以下であり、6-クロロ-3,4-ジヒドロピリジン-1(2H)-カルボニルクロリドが、ガスクロマトグラフィーによって検出できず、iPrOH中に50%溶解したトルエンスルホン酸一水和物を不活性化剤として使用したという点で異なる。
例2に記載された装置において、6-クロロ-3,4-ジヒドロピリジン-1(2H)-カルボニルクロリドの含有量が、開始時に指定された純物質の添加により190ppmに調整された200gのPDIと、800gのHDIとの混合物を最初に投入し、例2に記載された手順と同様に処理したが、不活性化剤のモル量を、NCO含有量が、
a)約47.0+/-0.5%
b)約33.0+/-1%
に低下した後に使用した触媒の量と同等に計量したという点が異なる。
本発明による方法によって生成された例3~6のすべての生成物は、密閉されたアルミニウム容器内で50°Cで保存され、6ヶ月の期間にわたって定期的にそれらの発色に関して試験した。どのような場合でも、ハーゼン色数の大幅な増加は観察できず、場合により、最大30APHAの大幅な明るささえ発生した。
