    • The invention relates to a process for preparing di-n-butene and alkyl tertbutyl ethers in a coupled production from field butanes, which indicates (a) separating the field butanes 1 into n-butane and isobutane in the separation stage 4, (b) dehydrogenating the n-butane 5 in a dehydrogenation stage 6 to give an n-butene-containing dehydrogenation mixture 7, oligomerizing the n-butene in the oligomerization stage 10 to give an oligomer mixture 11 and separating di-n-butene 12 off from this, and (c) de-hydrogenating the isobutane 15 in the dehydrogenation stage 16 to give an isobutene-containing dehydrogenation mixture 17 and reacting the isobutene with an alkanol 20 in the etherification stage 19 to give an alkyl tert-butyl ether 21. In an advantageous embodiment, the field butanes 1, prior to entry into the separation stage 4, are subjected to hydrogenation conditions in the hydrogenation stage 2 and an isomerization stage 3 is assigned to the separation stage 4, by means of which isomerization stage the ratio of n-butane to isobutane is set in accordance with the desired ratio of alkyl tertbutyl ether to di-n-butene.
    • 本发明涉及一种从场丁烷偶联制备二正丁烯和烷基叔丁基醚的方法,其表明(a)在分离段4中将场丁烷1分离成正丁烷和异丁烷;(b) 在脱氢阶段6中使正丁烷5脱氢,得到含正丁烯的脱氢混合物7,使低聚反应阶段10中的正丁烯低聚,得到低聚物混合物11,并从其中分离出二 - 正丁烯12 ,和(c)脱氢阶段16中的异丁烷15脱氢,得到含异丁烯的脱氢混合物17,并使异丁烯与醚化阶段19中的链烷醇20反应,得到烷基叔丁基醚21.在 有利的实施方案中,进入分离阶段4之前的现场丁烷1在氢化阶段2中经受氢化条件,异构化阶段3分配给分离阶段4 根据所需的烷基叔丁醚与二正丁烯的比例来设定正丁烷与异丁烷的比例。
