[". 중화반응을 통해 해결

Thread Content

제 원료 및 비율: 33kg의 间甲苯胺 83kg의 합성염산을 사용하여 반응 5분 동안 실시하고, 冰块 降温至 -℃, 시작하여 미리稱量好的 1 from 13kg의 아노산나트륨 용액을 천천히 투여하면서 冰中 持续降温, 시간은 35분 이내로 유지해야 합니다. 이때 발생한 문제는 투여량의 2分之三时 反应釜内开始起沫,并 투여 완료 후 반응액 위에 약 5cm 두께의 泡漂浮着. 이 원인은 무엇이며, 收率的影响有多大吗?以及如何解决?请专业人士指导

공정 조절을 제대로 하지 Rencontre工艺控制点没有控制好,对收率有很大的影响。

안녕하세요, 你还在做间氯甲苯么?

你还在做间氯甲苯吗?加料速度太快,重氮盐分解了?降低亚硝酸钠速度试试加冰时分批加。不要一次加很多。或者还有可能是亚硝酸钠加料太快,来不及和间甲苯胺重氮化就和盐酸反应生成了,气体。有没有看到反应釜内有红色气体?
