Description
| - Mechanismus kysele katalyzovaného rozkladu 3-alkyl-1,3-difenyltriazenů trichloroctovou kyselinou v hexanu (cs)
- Eight 3-alkyl-1,3-diaryltriazenes with substituents methyl, ethyl, propyl, butyl, pentyl, isopropyl, sec-butyl and cyclohexyl have been synthesised and their rate constants of decomposition by trichloroacetic acid (0.01 ? 0.25 mol dm?3) in hexane medium at 25 oC measured. The kinetic model and mechanism thereof was suggested with the use modelling of the dependences of kobs on the concentration of trichloracetic acid. On the basis of this kinetic model and the interpretation of solvent effects, the reaction mechanism has been suggested according to which the triazene reacts with monomer and obviously also opens the dimer of trichloroacetic acid in a single reaction step. At the same time, a non-reactive associate between N1 nitrogen of triazene and two molecules of trichloroacetic acid is formed in the reaction mixture. The equilibrium and rate constants depend on the addition of trichloroacetic acid as the co-solvent.
