摘　　要：以竹材为原料,探讨了在不同浓度有机溶剂、盐酸和催化剂等条件下,丙酮制浆对纤维长度的影响。丙酮制浆对纤维长度具有显著的影响,随着丙酮及酸浓度的增加,纤维长度减小;而随催化剂量的增加,纤维长度增长。在丙酮20%,盐酸浓度2%及催化剂浓度30g/L条件下,分离纤维的长度变化较小,且木素得率较高,分离效果较好。The effect of acetone pulping of bamboo on the fibre length under different conditions of organic solvent, HCl and catalyzer is studied in the paper. Acetone pulping has a remarkable influence on the fibre length： with the increase of the concentration of acetone and acid, the fibre length decreases; with the increase of catalyzer charge, the fibre length increases. When the concentration of acetone and HCl are 20% and 2% respectively, the concentration of catalyzer is 30g/L,the length variation of the separated fiber is at the minimum and the yield of lignin is higher with a preferable separating effect.
