Detection of Hydrogen Cyanide. A Test Readily Adaptable for the XM256 Chemical Agent Detector Kit

摘要

A successful test for hydrogen cyanide was developed for the XM256 chemical agent detector kit. Prior to the detection, papers impregnated with cupric acetate were spotted with a solution of p,p'-tetramethyldiaminodiphenylmethane (tetrabase) in methyl alcohol. The immediate appearance of a deep blue coloration against a very light blue background indicated the presence of hydrogen cyanide. The cupric acetate papers and tetrabase-methyl alcohol solution passed the heat stability requirement (65C for 30 days). (Author)
