Removal of non-cellulose component of bamboo material by formic acid

The removal effect of formic acid on the non-cellulose component of natural bamboo material was discussed.The results show that the removal effect on non-cellulose component of bamboo material was significantly enhanced by inorganic acid catalysts,and hydrochloric acid′s catalysis effect was the best among nitric acid,sulfuric acid and hydrochloric acid.Formic acid can effectively remove the non-cellulose component of bamboo material,but almost has no effect on the cellulose component.Formic acid′s concentration,reaction temperature and reaction time are three factors that have important influence on the removal ratio of non-cellulose component of bamboo material,and the influence effect of the three factors is concentrationtemperaturetime;The optimum treatment conditions were found to be: HCI 0.3%(volume fraction) as the catalyst,formic acid 80 g/L(volume fraction),reacting at 100 ℃ for 2 hours,and the removal rate is 42.8% under these conditions.
