ABSTRACT:
This invention relates to a method of making ethylbiphenyls by the reaction of biphenyl with polyethylbenzenes or with ethylene and polyethylbenzenes in the presence of a solid acid catalyst and offers advantages of industrial significance such as absence of acidic waste water, no need of costly materials for equipment, catalyst reuse, and adaptability to a fixed-bed flow reaction system suitable for large-scale production.
