摘要
测定苯甲醛水分含量一直采用甲苯蒸馏法。此方法费时、费力,很不利于节能减排。论述了采用库仑微量水分滴定仪法,该方法分析速度快、准确度高,更适合测量微量水分,同时污染小、不危害职工身体健康、能耗物耗低。
Toluene distillation method is always used to determine the water content of benzaldehyde. But it takes too much time and effort, and has some negative effect on energy-saving and emission-reducing. This paper introduces the coulomb titrator method for determining the micro water content. And points out its advantages for determining micro water content： fast and exact analyses, less pollution, no personal damage to operators, low energy and material consumption.
