羧甲基羟乙基纤维素的制备
Synthesis of Carboxymethyl-Hydroxyethyl-Cellulose
【摘要】 本文以羟乙基纤维素作为原料制备混合醚羟乙基羧甲基纤维素 ,在本实验范围内 ,最佳反应温度为 50℃ ,加入四硼酸钠降低了产物的取代度 ,但有利于提高其溶解速度。该产品在水中速溶 ,且粘度稳定
【Abstract】 In this paper, hydroxyethyl carboxymethyl cellulose (HECMC) was synthesized by hydoxyethyl cellulose (HEC) as material. In our investigation, the best reaction temperature was 50℃. When Na 2B 4O 7 was added into reaction system, the DS of CMHEC decreased, but its dissolution speeded up.The product could dissolved quickly in aqueous, and its viscosity was stable.
