简介：dichloro-methoxybenzenes的合成和动力学在353383K的一个温度范围从1,2,4-trichlorobenzene和钠甲氧化物被学习。反应物，溶剂和反应温度的臼齿的比率的效果被调查。反应产品包括三异构体。为三异构体的选择的顺序是1,4-dichloro-2-methoxybenzene>>2,4-dichloro-1-methoxybenzene>1,2-dichloro-4-methoxybenzene。为在1,2,4-trichlorobenzene和钠甲氧化物之间的平行液体固体接口反应的运动方程当催化剂不在时被建立。象pre指数的因素和激活精力那样的运动参数与Arrhenius方程被决定。
