Cyanide chloride, also known as chloromethyl cyanide, is a compound with the chemical formula CNCl. It is a colorless liquid or gas, slightly sweet, and highly soluble in most organic solvents such as water, ethanol, and ethyl alcohol. After dissolving in water, it becomes weakly acidic. The chemical reactivity is high and can react with many chemical substances. It is prone to decomposition when heated, and can react with water or steam, even causing violent reactions, while releasing strong and corrosive smoke. It can react with sodium hydroxide to produce sodium cyanate, with sodium sulfide to produce sodium thiocyanate, with ammonia or amines to produce cyanamide, and with alcohols to produce cyanurate.
Haohan Chromatography uses gas chromatography to determine the content of cyanide chloride in industrial waste gas. The GC790 gas chromatograph, HH-CNCL-III chromatographic column, and external standard method are used for quantification. The concentration of cyanide chloride shows a good linear relationship with peak area in the range of 0.1-10 mol/mol, with a correlation coefficient greater than 0.999. The relative standard deviation of 9 repeated measurements is less than 4%, and the sample recovery rate is 95%~104%. The results show that this method is simple, fast, accurate and reliable, and can meet the testing of cyanide chloride content in waste gas
