制取苯胺后仪器残留物的清洗方法

Study on Method of Removal of Residua on Glass Instruments After Preparation of Aniline

通过对制取苯胺后仪器残留物的成分及其成因分析,寻找清洗残留物的最佳方法.根据残留物的性质,将机械冲洗、碱洗、酸洗、氧化清洗和络合清洗等方法结合使用,清洗后仪器壁上不留任何残留物,水洗倒挂壁上形成均匀水膜,完全可再次用于实验操作.该方法很好地解决了制取苯胺后仪器残留物难以清洗的问题,对实验室相关实验和工业生产有一定的指导作用.

In order to seek the effective method for removing the residua on glass instruments,the composition of residua during the preparation of aniline was investigated. The best effective method for removing the residua was obtained using the combination of mechanical swashing,and alkalescent swashing,and acidic swashing,and oxidation swashing.After swashing,the glass instruments could be applied,without anything residua and even water film on them.This method solved the problem of removal of residua on glass instruments after preparation of aniline,and could be applied to lab and industrial operation.
