摘要
在乙醇溶液中，以Ｈ２Ｏ２为氧化剂，以ＫＩ／ＮａＡｃ为催化剂，由甘蔗渣纤维制备羧甲基纤维素．产品有效成分８５％～９５％，粘度５００～８００ｍＰａ·ｓ，取代度０．６５～０．８０，氯化物＜３％．
Carboxymethyl celluloses were prepared from bagasse fibers via oxidation (oxidant:H2O2), alkalization and etherification (catalyst:KI/NaAc) in the solution of 95% ethanol. The available component and the content of chloride of CMC are 85%～95% and <3%, the substituting degree and the viscosity of CMC being 0.65～0.80 and 500～800 mPa·s.
