Abstract
Bromo-2′,4′-dichloroacetophenone was synthesized in three steps,w hich were bromization ,chlorination and acylation,from glacial acetic acid and m -dichlorobenzene.The yield was 70%.The structure of 2-bromo-2′,4′-dichloroacet ophenone was confirmed by 1HNMR, 13 CNMR and IR spectra analysis.I ts p hysical constants including relative density(ρ),refractive index(n 25 D) ,boiling point(b.p.) and melting point(m.p.) were measured.
