一步法合成甲基橙实验条件的优化

研究了常温下一步合成甲基橙的实验方法,优化条件为室温下pH=10时,反应搅拌时间25min.与低温法相比,减少了原料的消耗,降低了制备成本,低温方法制备甲基橙的产率为76.6%,常温一步法的产率为85.1%提高了产率.

Optimum Conditions for Synthesis of Methyl Orange Using One Step Method

The synthesis of methyl orange at room temperature in one step was studied.The optimum experimental condition was found to be: room temperature,stilling time: 25min,and pH: 10.Compared to the synthesis of methyl orange at lower temperature,this method has the advantage of reduced to material consumption and lower cost and higher yield.The yields of methyl orange at the lower temperature and room temperature are 76.6% and 85.1% respectively.
