Description
のアミノ−またはヒドロキシベンゾニトリルの製造方法であり、一般式(II):
2−ヒドロキシベンゾニトリルの製造および精製
1)製造工程
以下に記載される製造に関して以下の方法で得られる燐酸硼素担体触媒を使用した。
85%オルト燐酸5.88gおよび99.8%ホウ酸3.33gを蒸留水500gに溶解した。硫酸亜鉛3.6gを更に溶解後、この溶液を室温で1時間攪拌し、引き続き比表面積が400m2/gより大きいシリカゲル500gを添加した。シリカゲルの細孔直径は0.4〜25nmであった。引き続き減圧下、60℃で乾燥するまで蒸発させ、弱い空気流を通過させながら3時間かけて150℃に加熱した。冷却後、こうして得られた担体触媒を以下に記載するように使用できた。
製造工程1)により得られた粗製生成物500gを予め入れ、水性アンモニア1500ml(32%溶液として)と混合し、引き続き室温で60分攪拌した。
