小毛竹笋壳提取合成羧甲基纤维素钠的研究
|
摘要
本文以福建大宗农业废弃物—毛竹笋壳为原料,经酸泡、碱煮、漂白等工艺提取纤维素,并对其进行化学改性,合成了羧甲基纤维素钠产品,取代度为0.86,黏度为22mPa·s,达到医药行业的应用标准。最后利用FTIR及XRD衍射分析对产品进行了表征,通过与商品级CMC比较,验证了羧甲基纤维素产品的成功合成。
Sodium carboxymethyl cellulose have widely used in society. In this work,moso bamboo shell as a large amount of agricultural waste in Fujian province were chosen to synthesis it. Firstly,cellulose was extracted by acid treatment,alkali boiling and bleaching from moso bamboo shell. Then,sodium carboxymethyl cellulose with degree of substitution 0. 86 and viscosity 22mPa·s was prepared through chemical modification of the cellulose. In the end,the FTIR and XRD have been used to character the product and it has proved CMC can be synthesised successfully from moso bamboo shell with comparing its marketable grade.
