从木质生物质温和液化残渣中提取纤维素，并对其进行 FTIR、XRD 表征；以提取出的纤维素为原料，经碱化、醚化合成羧甲基纤维素钠（CMC）。合成的 CMC 的取代度略大于从木质生物质中直接提取纤维素合成的 CMC 的取代度，水溶性较好，2％水溶液黏度小于50 mPa·s，属于低黏度产品。
從木質生物質溫和液化殘渣中提取纖維素，併對其進行 FTIR、XRD 錶徵；以提取齣的纖維素為原料，經堿化、醚化閤成羧甲基纖維素鈉（CMC）。閤成的 CMC 的取代度略大于從木質生物質中直接提取纖維素閤成的 CMC 的取代度，水溶性較好，2％水溶液黏度小于50 mPa·s，屬于低黏度產品。

Cellulose was extracted from mild liquefaction residue of woody biomass and characterized by FT-IR and XRD.Then it was used as a raw material to synthesize carboxymethylcellulose sodium(CMC)by alkali-zation and etherification.The synthetic CMC had higher substitution degree than that of CMC synthesized by cellulose extracted directly from woody biomass,and had better water-solubility.The viscosity of 2% aqueous solution of the CMC product was less than 50 mPa·s,and belonged to low viscosity product.
