摘要
以3-氯-2,2-二甲基丙酰氯为原料,经酰化、环合、缩合制得异噁草酮,总收率达到70%以上。采用氯化氢和冷却结晶的方法,使异噁草酮原药的纯度达到95%以上。
clomazone is prepared starting from 3-chloro-2,2-dimethyl-propionylchloride by acylation, eyelization and condensation.The total yield is more than 70%.The purity of clomazone technical is up to 95% by introducing anhydrous hydrogen chloride gas into the crude product and then Cooling it.
