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.
