通过采用过氧酸体系法、有机溶剂法以及硝酸-乙醇-硫酸法等6种方法提取蔗渣纤维素,综合比较其纤维素含量、聚合度、提取所需时间以及外观形态等各项指标,以期找出提取蔗渣纤维素的最佳方法。结果表明:6种方法中,硝酸-乙醇-硫酸法最为优越,此法提取的纤维素含量最大,达到84.68%,同时耗时最短,仅3.5h,聚合度中等,且纤维素呈白色花粉状,有广阔的工业生产前景。
By using peroxyacid system method, organic solvent method and nitric acid - ethanol - sulfuric acid method, six kinds of methods were used to extract bagasse cellulose, and the contents of cellulose, polymerization degree, extraction time and appearance were compared comprehensively Find the best method to extract bagasse cellulose. The results showed that the best of the six methods was nitric acid-ethanol-sulfuric acid method. The content of cellulose extracted by this method reached 84.68%, the shortest time was 3.5h, the degree of polymerization was medium, and the cellulose was white pollen , A vast industrial production prospects.
