The kinetics of decarboxylation of \(\propto\)-picolinic acid in eight additional organic solvents has been studied under inert. atmosphere of nitrogen. The activation parameters of the reaction are calculated. The solvent effect on the kinetics of the reaction is discussed. The possibility of chelated picolinic acid molecule rather than zwitterion to act as an initial reactant Is favoured. An isokinetic temperature of 149^o is obtained.
