- W2378635993 abstract "The Friedel-Craft acylation of acenaphthene with benzoyl chloride catalysed by Cl/AlCl_3 room temperature ionic liquid to synthesize 3,6-bibenzoylacenaphthene,which could be used as new functional macromolecule intermediate and fine chemical,was investigated.The effects of various reaction conditions on the yield and selectivity of 3,6-dibenzoylacenaphthene were studied by GC analysis.The results showed that the optimum synthesis conditions of the desired product are as follows: the molar fraction of AlCl_3 in Cl/AlCl_3,0.67;the mole ratio of Cl/AlCl_3 to acenaphthene,6;the mole ratio of benzoyl chloride to acenaphthene,6;the reaction temperature,45 ℃;and the reaction time,8 h.Under those conditions,the yield of 3,6-dibenzoylacenaphthene is 88.4 % and the selectivity towards 3,6-dibenzoyl acenaphthene is 90.5 %.Furthermore,Cl/AlCl_3 has little pollution to environment and can be reused.Pure 3,6-dibenzoylacenaphthene was prepared by extraction and recrystallization and the structure of 3,6-dibenzoylacenaphthene was identified by GC,GC/MS,FT IR and ~1H NMR analyses." @default.
