    • The present invention relates to a process for the preparation of 2-ethylhexanal by catalytic hydrogenation of 2-ethylhex-2-enal, wherein the hydrogenation is carried out in a plurality of two or more series-connected loops, wherein each loop involves the use of one reactor, which comprises: (a) feeding 2-ethylhex-2-enal and hydrogen to an upper part of a reactor to catalytically hydrogenate said 2-ethylhex-2-enal to produce a hydrogenation product, (b) recycling a portion of said hydrogenation product back into said upper part of said reactor, (c) feeding the remainder of said hydrogenation product from said reactor to an upper part of a subsequent reactor wherein 2-ethylhex-2-enal is catalytically hydrogenated to produce a subsequent hydrogenation product, and wherein a portion of said subsequent hydrogenation product has been recycled and is fed with said remainder of said hydrogenation product to said upper part of said subsequent reactor, (d) repeating step (c) until the subsequent reactor is the last reactor, (e) recovering the remainder of said subsequent hydrogenation product from said last reactor, and (f) obtaining 2-ethylhexanal from the product of step (e).
    • 本发明涉及通过2-乙基己-2-烯醛的催化氢化制备2-乙基己醛的方法,其中氢化在多个两个或多个串联连接的环中进行,其中每个环包括使用 的一个反应器,其包括:(a)将2-乙基己-2-烯醛和氢气加入到反应器的上部以催化氢化所述2-乙基己-2-烯醛以产生氢化产物,(b)将部分 的所述氢化产物回到所述反应器的上部,(c)将剩余的所述氢化产物从所述反应器进料到后续反应器的上部,其中2-乙基己-2-烯醛被催化氢化以产生随后的氢化 产物,并且其中所述后续氢化产物的一部分已经被再循环,并且将所述剩余的所述氢化产物进料到所述后续反应器的所述上部,(d)重复步骤(c)直到亚序列 t反应器是最后一个反应器,(e)从所述最后一个反应器回收剩余的所述后续氢化产物,和(f)从步骤(e)的产物得到2-乙基己醛。

    • The invention is a method for processing a mixture containing water, 3-methyl-1-butene 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-丁烯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。
