Determination of Moisture Content in Hydrogen Cyanide Samples Produced by Acrylonitrile Process
The cyanide industry,as an important branch of the inorganic salt industry,plays a very important role in the development of China's economy.The purity,moisture content,impurity content,and other indicators of hydrocyanic acid have a significant guiding effect on process production.The Karl Fischer method is a universal method for determining the moisture content in samples.Any moisture present in the sample(free water or crystalline water)is quantitatively reacted with a known equivalent of Karl Fischer reagent to detect moisture in the sample.This article provides a detailed description of the detection of hydrogen cyanide water,a byproduct of the acrylonitrile process,from sample collection to moisture detection,as well as various possible issues that may arise during the process.
