Abstract

Un procedimiento para preparar alquil-terbutil éteres y di-n-buteno a partir de butanos naturales y en una producción acoplada, alquil-terbutil éteren calidad deaditivo para la gasolina, empleo de di-n-buteno para preparar materias primasdetergentes en el cual a) en una etapa de deshidrogenación 2 sedeshidrogenan juntos el n-butano y el isobutano contenidos en los butanos naturales 1 para obtener una mezcla de deshidrogenación 3 que contiene n-butenoe isobuteno, b) se conducel a mezcla de deshidrogenación 3 hacia la etapa de eterificación 4, en donde el isobuteno se hace reaccionar en forma selectivacon un alcanol 5 para obtener un alquil-terbutil éter 6, y c) se conduce la mezcla residual de deshidrogenación 7haci a la etapa de oligomerización 8 endonde se oligomeriza el n-buteno en forma catalítica. En una forma de realización preferida del procedimiento se someten los butanos naturales 1,antes de ser conducidos hacia la etapa dedeshidrogenación 2, a las condiciones de hidrogenación de una etapa de hidrogenación 9, y se hacen pasar hacia unaetapa de separación 10 a la que se agrega una etapa de isomerización 11 mediante la cual se puede ajustar la relación n-/iso ala relación deseadae ntre las cantidades de di-n-buteno y de metil-terbutil éter, y finalmente se conduce el butano natural 1a, cuya relación n-/iso ha sido modificada de lamanera indicada, hacia la etapa de deshidrogenación 2. El proceso permite producir el n-bu teno y el isobuteno en un solo lugar en cantidades suficientesy sin tener que transportar el producto a través de largas distancias, tal como lo requiere una producción acoplada para la operación de una planta rentableyventajosa para la preparación de di-n-buteno a gran escala y de una planta similar para la obtención de RTBE. También permite acoplar ambas plantas deA process for preparing alkyl tert-butyl ethers and di-n-butene from natural butanes and in a coupled production, alkyl terbutyl ethers in gasoline additive quality, use of di-n-butene to prepare detergent raw materials in which ) in a dehydrogenation step 2, the n-butane and isobutane contained in the natural butanes 1 are dehydrogenated together to obtain a dehydrogenation mixture 3 containing n-butenoe isobutene, b) it is conducted to a dehydrogenation mixture 3 towards the etherification step 4, where the isobutene is selectively reacted with an alkanol 5 to obtain an alkyl-tert-butyl ether 6, and c) the residual dehydrogenation mixture is conducted 7haci to the oligomerization step 8 where the n-butene is oligomerized in a catalytic form . In a preferred embodiment of the process, the natural butanes 1 are subjected, before being led to the dehydrogenation stage 2, to the hydrogenation conditions of a hydrogenation stage 9, and are passed to a separation stage 10 at which adds an isomerization step 11 by means of which the n- / iso ratio can be adjusted to the desired ratio between the amounts of di-n-butene and methyl tert-butyl ether, and finally natural butane 1a, whose ratio n- / iso has been modified in the indicated way, towards dehydrogenation stage 2. The process allows to produce n-bu teno and isobutene in one place in sufficient quantities and without having to transport the product over long distances, such as It requires a coupled production for the operation of a profitable and advantageous plant for the preparation of di-n-butene on a large scale and a similar plant for obtaining RTBE. It also allows coupling both plants of
