N. ABSTRACT. The reaction rates of substituted 6-chloroquinoline, with p-substituted benzoyichlorides (p-CH 3, pH, p-NO2) have been measured by conductometry in acetonitrile, and the rate constants are determined at various temperatures (10, 15, 20, 25 oC) and pressures (1, 200, 500, 1000 bar). From the values of rate constants, the activation parameters (Ea, ∆V≠, ∆H≠, ∆S≠, and ∆G≠) and the pressure dependence of Hammett ρ values were determined. The rate constants increased with increasing temperatures and pressures, and are further increased to introduction to the electron donor substituents in substrate (p-NO 2) with 6-chloroquinoline. When, the activation volume and the activation entropy are all negative. And the Hammett ρ values are positive for the substrate over the pressure and temperature range studied. The results of kinetic studies for pressure and substituent show that thease reactions proceed in typical S N2 reaction mechanism and “associative SN2” in bond formation favored with increasing pressures. Keywords: Kinetics, Pressure, Nucleophilic Substitution Reaction. 187.
