4-Ethylbenzophenone was synthesized utilizing the Friedel-Crafts acylation from the precursors of ethylbenzene and benzoyl chloride, catalyzed by aluminum chloride. Characterization was achieved via refractometry, GC-MS, IR and HNMR. Refractometry yielded a refractive index of 1.5932 ± 0.0001, notably higher than literature value indicating the presence of impurities. GC-MS detected the...
