对氨基苯甲酸制备
1.在反应锅内依次加入水、氯化钠、盐酸。开动搅拌并升温至50-60℃,加入9/10量的铁粉,继续升温到98-102℃,保温1h,停止加热,于95℃慢慢加入对硝基苯甲酸,约1-1.5h加完,补加铁粉,在98-102℃保温1h,放冷至80℃,加入30%液碱调节pH=8.5-9,压滤,用少量水洗,滤液与少量洗液合并,压入酸析锅,冷至30-34℃,加入保险粉脱色,过滤。滤液加酸调节pH=3.5-4,继续冷至10℃以下,甩水、干燥即得成品。收率84-88%。(2)由对硝基苯甲酸经催化加氢而得在1000ml烧杯中加入工业品对硝基苯甲酸及水,在搅拌下用22%氢氧化钠调整pH=6-7,然后加阮尼镍,在搅拌下把料液抽入摇摆式高压釜中,分别用氢气、氮气各置换两次、再充压至3.43MPa,在压力3.43-2.54MPa、温度134-140℃下反应5h左右,至氢压不下降为终点。反应结束后过滤、干燥而得成品。收率80%以上。
2.工业生产主要有两种方法。
(1)对酯基苯甲酸经铁粉还原而成。反应式如下:
(2)由对硝基苯甲酸经催化加氢而得。反应式如下:
