    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。

    Abstract: A gas mixture (obtained by thermal cracking of hydrocarbons followed by quenching of the cracked gas and freed from carbon dioxide and water) is separated into a gas mixture containing hydrogen, carbon monoxide and methane and another gas mixture containing ethylene, acetylene and higher hydrocarbons by (a) cooling the gas mixture which is at superatmospheric pressure in at least one condensation stage to a temperature which is above the solidification temperature of acetylene mixed with the other condensed constituents, (b) separating the condensate thus obtained and subdividing it in a rectifying column into a first mixture containing C2 hydrocarbons and a second mixture containing C3 and higher hydrocarbons, and (c) freeing the residual gas remaining from (a) from residual acetylene and ethylene in a scrubber by treatment with some of the mixture consisting of C3 and higher hydrocarbons from (b).
