本发明公开了一种高纯度乙基氯化物的清洁制备方法,在乙基硫化物粗产品进入氯化工序前,先用薄膜蒸馏、再用分子蒸馏的方法对其进行纯化,分离掉硫化氢气体、中性油和残渣等杂质后送入氯化工序,以减小氯化过程中副产物的发生,把氯化后所得的乙基氯化物粗产品过滤后先进行薄膜蒸馏,再用 The invention discloses a clean preparation method of high-purity ethyl chloride. Before the crude ethyl sulfide product enters the chlorination process, thin-film distillation and then molecular distillation are used to purify the crude product, and the hydrogen sulfide is separated Gas, neutral oil and residue and other impurities into the chlorination process, in order to reduce the occurrence of chlorination by-products, the chlorinated crude ethyl chloride obtained after filtration thin film distillation, reuse
