用t0.9法,选择四个温度进行恒温加速实验。用HPLC法测定CPRD浓度,求出1/T与Int0.9之间的Arrhenius直线方程为1nt0.9=13.57×1/T-40.24,r=0.9935。预测COS的稳定性月,17d。实测。
With t0.9 method, choose four temperature thermostatic acceleration experiment. The concentration of CPRD was determined by HPLC, and the Arrhenius equation of 1 / T and Int0.9 was found to be 1nt0.9 = 13.57 × 1 / T-40.24 and r = 0.9935. Predicting the stability of COS month, 17d. Measured.
