662:. The activity coefficients of each component were accurately calculated using the Wilson method, then, the equilibrium constants was obtained. The effect of catalyst size, stirring rate, temperature and EtOH/2M1B molar ratio was investigated at the chosen pressure, respectively. A kinetic model which considered the variation of each component volume was established. The method of nonlinear least square combined with genetic algorithm (NLS-GA) was proposed to estimate the kinetic constant in the forward direction. Results indicated that simulated kinetics results were agreed well with the experimental data.

TAME exposure significantly increased relative liver weights in the high and mid-dose groups. However, no treatment-related histopathologic findings were noted for the compound. Clinical chemistry and hematology findings were minimal with TAME exposure. The results indicate that 500 ppm was a
