    • The invention is a method for processing a mixture containing water, 3-methyl-1-butane and at least one other methylbutene. The method comprises primary distillation of the mixture, giving a gaseous primary overhead product containing methylbutene and water and a water-free primary bottom product containing 3-methyl-1-butene; condensation of the gaseous primary overhead product so as to give a condensate comprising a liquid aqueous phase and a liquid organic phase; separation of the condensate into a liquid aqueous phase and a liquid organic phase; discharge of the liquid aqueous phase; recirculation of the organic phase to the primary distillation; and finally secondary distillation of the water-free primary bottom product from the primary distillation so as to give a secondary overhead product comprising 3-methyl-1-butene and a secondary bottom product. The secondary overhead product obtained has a purity which enables it to be used directly as monomer or comonomer for preparing polymers or copolymers.
    • 本发明是一种处理含有水,3-甲基-1-丁烷和至少一种其它甲基丁烯的混合物的方法。 该方法包括对该混合物进行一次蒸馏,得到含有甲基丁烯和水的气态初级塔顶馏出物和含有3-甲基-1-丁烯的无水初级底物产物; 气态一级塔顶产物的冷凝,以产生包含液态水相和液体有机相的冷凝物; 将冷凝物分离成液态水相和液体有机相; 液体水相的排出; 将有机相再循环至初级蒸馏; 最后从初级蒸馏二次蒸馏无水初级底部产物,得到包含3-甲基-1-丁烯和二级底部产物的二级塔顶产物。 获得的二次塔顶产物具有使其能够直接用作制备聚合物或共聚物的单体或共聚单体的纯度。
