摘　　要：以自制的煤基活性炭负载硫酸为催化剂,β-萘酚、醛和脂肪醛为原料,用一锅法成功合成了11个14-烷基(芳基)-14H-二苯并[a,j]氧杂蒽类化合物,反应时间0.1～1h,收率71%～96%.该方法不仅反应时间短,产率高,而且催化剂价廉易得,对环境友好,可重复利用5次,活性没有明显降低,并测得催化剂的酸值为3.06mmol/g.Eleven 14-alkyl（aryl）-14H-dibenzo[a,j] xanthenes were one-pot successfully synthesized from β-naphthol and alkyl（aryl） aldehydes using the H2SO4 loaded coal based activated carbon as the catalyst in a solvent-free medium.The reaction time was 0.1～1 h,and the yield ranged from 71% to 96%.The catalyst was inexpensive and environmentally friendly,and could be recycled at least five times without significant decrease in its catalytic activity.And catalyst for the acid value was 3.06 mmol/g.
