| titleOfInvention | Production of tetraethylbenzene |
| abstract | PURPOSE: To advantageously obtain the title compound by reacting benzenes containing diethylbenzene and triethylbenzene with an ethylating agent in the presence of a solid acid catalyst, separating the title compound from other ethylbenzene by distillation and returning an unreacted raw material to the reaction system. n CONSTITUTION: Benzenes containing diethylbenzene or triethylbenzene are reacted with an ethylating agent in the presence of a solid acid catalyst and ethylated until an amount of ethyl group per mol of benzene ring becomes 3.6-4.8mol and then subjected to rearrangement reaction of ethyl group in the presence of the above-mentioned catalyst and then (a) tetraethylbenzenes and (b) other ethylbenzenes are separated from the resultant reaction product by distillation. Further, at least part of fraction containing diethylbenzene or triethylbenzene is returned to the above-mentioned reaction system. Thereby tetraethylbenzene useful as a solvent or heat medium, etc., is industrially advantageously and selectively obtained in good yield. n COPYRIGHT: (C)1991,JPO&Japio |
