Abstract
Inventia se refera la un procedeu de obtinere a alchilbenzenilor, respectiv a etilenbenzenului si izopropilbenzenului, în care material prima este alcatuita dintr-un amestec de vinil-benzeni, respectiv etilbenzen, stiren, izopropilbenzen si alfa-metilstiren, vinilbenzenii fiind continuti în proportie de 5...50% în greitate, de preferinta 30% în greutate, raportul dintre stiren si alfa-metilstiren si, de asemnea între etilbenzen si izopropilbenzen variind în orice proportie, se supune hidrogenarii în prezenta unui catalizator de paladiu depus pe suport de alumina granulata, reactia decurgînd la temperatura de 120...150 degree C, presiune 2...3 at, la o viteza volumara de 1...2 h-1 si cu raport molar hidrogen/hidrocarbura de 5/1 pîna la 10/1.The invention relates to a process for the production of alkylbenzenes, respectively of ethylenebenzene and isopropylbenzene, wherein the first material is composed of a mixture of vinylbenzene, ethylbenzene, styrene, isopropylbenzene and alpha-methylstyrene respectively, the vinylbenzenes being 5 ... 50% by weight, preferably 30% by weight, the ratio of styrene to alpha-methylstyrene, and also between ethylbenzene and isopropylbenzene ranging in any proportion, is subjected to hydrogenation in the presence of a palladium catalyst deposited on granulated alumina support , the reaction resulting from a temperature of 120 ... 150 ° C, a pressure of 2 ... 3 atm at a volumetric speed of 1 ... 2 h-1 and a hydrogen / hydrocarbon molar ratio of 5/1 to 10 / 1.
