| Abstract: | Fir char sulfonic acid was prepared by pyrolysis and sulfonation from fir processing residues.FT-IR and XPS showed that sulfonated groups had successfully bonded to the charcoal skeleton.The good catalytic properties of fir char sulfonic acid were investigated in the Pechmann condensation reactions of ethyl acetoacetate and substituted phenols.Several 4-methyl coumarin derivatives had been synthesized.The effects of catalyst amount etc.on the yield were investigated.The catalytic performance of fir char sul... |
