The association behavior of coal tar pitch soluble components TS in toluene was studied by hydromechanics method. The critical association concentrations of TS in toluene were obtained by viscosity curves at different temperatures. The kinetics parameters of nucleation and micelle stage in association process were calculated. The results show that the viscosities of TS solution increase with increasing concentrations at 293~353 K, and the turning-points appear between 13 and 26 g/L. The turning-points shifted backward along the axis with increasing temperatures. Both the nucleation and micelle stage are first-order associated reaction. The activation energies for the two stages are 17.25 and 12.41 kJ/mol, respectively.
