HCID 121601-Ethyl-4-MethylbenzeneYield 90.1%

Procedure

STDP and ethylation of toluene were carried out in the same manner as Examples 5 and 6. STDP gave a toluene conversion rate of 5.7% with a xylene product having 65.9% of the para isomer. Ethylation of toluene yielded 90.1% para-ethyltoluene in the ethyltoluene product at a toluene conversion of 20.0%.
