Description
固体塩基性触媒の製造
攪拌器と凝縮器が設置されている1000mlの四つ口フラスコに200gのD201樹脂と400gの25wt%TMAH水溶液を入れる。混合物を攪拌しながら加熱し、約75℃の温度で還流を維持する。還流反応は6時間持続する。反応混合物が室温まで冷却した後、フラスコに移動させて待機させる。濾過、水洗を経た後、水酸化テトラメチルアンモニウムを含有する樹脂が生成される。攪拌器と凝縮器が設置されている500mlの三つ口フラスコに200gの水酸化テトラメチルアンモニウムを含有する樹脂と200mlの50wt%水酸化カリウム水溶液を入れる。該混合物を攪拌しながら加熱し、約50〜100℃の温度で還流を2時間維持する。その後、該混合物を冷却させる。濾過を経た後、湿っている固相触媒をオーブンで(50℃より低い、0.098MPA) 乾燥するまでゆっくり加熱する。乾燥している固体塩基触媒を乾燥器に保存させる。
固体塩基性触媒の製造
攪拌器と凝縮器が設置されている1000mlの四つ口フラスコに300gの活性酸化アルミニウム(粒子直径2〜3mm、中国萍郷市天力化工填料有限公司で生産)と400gの25wt%TMAH水溶液を入れる。混合物を攪拌しながら加熱し、約75℃の温度で還流を維持する。還流反応は6時間持続する。反応混合物が室温まで冷却した後、フラスコに移動させて待機させる。200gを攪拌器と凝縮器が設置されている500mlの三つ口フラスコに入れ、また200mlの50wt%水酸化カリウム水溶液を入れる。該混合物を攪拌しながら加熱し、約50〜100℃の温度で還流を2時間維持する。その後、該混合物を冷却させる。濾過を経た後、湿っている固相触媒をオーブンで(50℃より低い、0.098MPA) 乾燥するまでゆっくり加熱する。
触媒を利用して4-ADPAを合成する
攪拌器と凝縮器が設置されている500mlの三つ口フラスコに50gの実施例1で製造した固体塩基触媒と150mlのアニリンを入れる。混合物を75℃まで加熱し、圧力を約0.095MPaに維持する。温度が70〜75℃間に制御された時、50mlのニトロベンゼンを入れ、縮合反応を行う。混合物から反応過程で生成した水を分離し出す。10時間反応後、ニトロベンゼンの残留量に対して持続的に分析を行う。残留したニトロベンゼンが1%より少ない時、反応を停止させる。
固定触媒を利用して4-ADPAを合成する 60メッシュの網状物で50gの実施例2で製造した固相触媒を包み、実施例3と同様な反応条件を利用して4-ADPAを合成する。反応が完了された後、固相触媒を回収せず、反応装置に保留する。
実施例1で製造した触媒を実施例3の方法により重複して15回利用し、第15回目に縮合反応を触媒する時のニトロベンゼン転換率は依然として98.5%である。
実施例2で製造した触媒を実施例3の方法により重複して15回利用し、第15回目に縮合反応を触媒する時のニトロベンゼン転換率は68%である。
