Description
(触媒調製)
200ml四つ口フラスコ中に、湿潤状態の強酸性イオン交換樹脂(「ダイアイオンSK104H」:酸交換容量1.67mmol/g−湿潤状態、ダイアイオンは三菱化学の登録商標)40gおよび蒸留水80gを入れ、室温で攪拌し、イオン交換樹脂を洗浄した。洗浄液はデカンテーションにより廃棄し、再度蒸留水を導入した。この洗浄操作を5回繰り返した。
次いで、内径12mmのガラス管に上記の触媒7.5mlを充填し、触媒中の水分をフェノールで置換した後、アセトン濃度4.5重量%のフェノール溶液を26.3ml/hの速度で流通させ、触媒層温度70℃で反応を行った。フェノール溶液の流通開始後6時間目に反応管出口で採取した反応液をガスクロマトグラフィーにより分析した結果、アセトンの濃度は0.71重量%(アセトン転化率84.3%)、生成したp,p−BPAの濃度は14.1重量%であった。
(触媒調製)
200ml四つ口フラスコ中に、湿潤状態の強酸性イオン交換樹脂「ダイアイオンSK104H」酸交換容量1.67mmol/g−湿潤状態)40gおよび蒸留水100gを入れ、60℃で攪拌し、イオン交換樹脂を洗浄した。洗浄液はデカンテーションにより廃棄し、再度蒸留水を導入した。この洗浄操作を5回繰り返した。
次いで、上記の触媒7.5mlを採取し、実施例1と同条件で反応を行った結果、6時間後の反応器出口でのアセトン濃度は0.73重量%(アセトン転化率83.9%)、生成したp,p−BPAの濃度は14.6重量%であった。
(触媒調製)
実施例1において、イオン交換樹脂の洗浄を蒸留水で行った後、蒸留水80g(pH6.1)を加えるのに代えて、pH1.2の硫酸水溶液80gを加えた以外は、実施例1と同様の方法で触媒調製を実施した。この場合、2−(4−ピリジル)エタンチオールは直ちに溶解し、エマルジョンを形成することはなかった。デカンテーションで液を廃棄し洗浄操作を繰り返した後に回収したイオン交換樹脂中のメルカプト基およびスルホン酸基の残存量を測定した結果、変性率は15.2%であり、スルホン酸残存率は84.7%であった。
次いで、上記の触媒7.5mlを採取し、実施例1と同条件で反応を行った結果、6時間後の反応器出口でのアセトン濃度は0.79重量%(アセトン転化率82.7%)、生成したp,p−BPAの濃度は13.4重量%であった。
