Abstract: A method of manufacturing ethylbenzene in high yield by catalytic aromatization of the C8-cycloolefins obtained in the dimerization of unsaturated C4-hydrocarbons is described. Byproducts attributable to cracking, isomerization and decomposition of the raw material into its starting materials are virtually not detectable in the reaction product. The aromatization product can therefore be converted to styrene without prior distillation or purification.
Abstract translation: 描述了通过在不饱和C4烃的二聚中获得的C8-环烯烃的催化芳构化而以高产率制备乙苯的方法。 归因于原料裂解,异构化和分解成其原料的副产物实际上在反应产物中不可检测。 因此,芳构化产物可以在没有事先蒸馏或纯化的情况下转化为苯乙烯。
