Micellar Effects on the Formation of the 1,3,5-Trinitrobenzene-Cyanide Complex in Water

Abstract

The anionic σ-complex from cyanide ion and 1,3,5-trinitrobenzene in water was stabilized by cationic micelles. The binding of counter ions to the micellar head groups in hexadecyl-trimethylammonium cyanidefollowed a distribution model with the counter ion binding constant K_CN = 1400 mol^-1 dm³. The bromide-cyanide ion exchange constant, K^CN_Br, was equal to 1.28. These results rendered further support to the general applicability of the distribution model.
