摘要: 三唑酮在不同pH值和温度条件下水解动力学的测定结果表明:三唑酮在酸性条件下比较稳定,不易水解,但随体系pH值的升高,水解速度加快。温度升高有利于三唑酮的水解反应,酸性条件下水解活化能最大,温度升高对反应速率的影响最大。 

关键词: 三唑酮, 水解, pH值, 温度

Abstract: Kinetics of triadimefon hydrolysis was studied in water different in pH value and temperature.The results indicate that triadimefon was stable in acidic environment,but its hydrolytic rate accelerated with the rising pH value.Higher temperature was helpful to the hydrolytic process.The activation energy for hydrolysis of triadimefon was the highest in acid water,whereas the effect of temperature on hydrolytic rate was the greatest.

Key words: triadimefon, hydrolysis, pH, temperature
