Popis: International audience; the kinetics of the Cl-transfert reaction between chloramine and piperidine in a Raschig medium was studied at various temperatures, with variable concentrations of the two reactants. The influence of the pH on the interaction was examined at a pH ranging between 8.25 and 12.89. The Cl-transfert reaction resulted in the formation of 1-chloropiperidine, which, in the presence of NaOH, underwent a dehydrohalogenation leading to an endocyclic imine derivative: 2,3,4,5-tetrahydropyridine. The kinetics of the dehydrohalogenation was also studied at different temperatures, with variable concentrations of 1-chloropiperidine and NaOH. Kinetic and thermodynamic parameters were determined.
