The subject of this research is the colorimetric detection of alkyl isocyanides. The objective was to develop a microchemical detection method for n-, sec-, and tert-butyl isocyanides. Several aromatic amine-metal ion redox systems were investigated for the detection of alkyl isocyanides on filter paper or silica gel tubes. It was concluded that microgram quantities of isocyanides may be easily detected on filter paper or in silica gel tubes by using benzidine acetate-cupric acetate or p,p-tetramethyldiamino- diphenylmethane tetrabase- cupric sulfate reagents. Interferences include those substances that are known to interfere in the use of the same reagents for the detection of hydrogen cyanide. The lowest amount of n-, sec-, or tert-butyl isocyanide detectable is approximately 0.1 microgram.
