微晶纤维素

微晶纤维素用途

纤维素可以用作赋形剂。药用辅料,或称药用辅料,是指除药物成分外,在制药过程中使用的其他化学物质。药用辅料一般是指药物制剂中的非活性成分,可以提高药物制剂的稳定性、溶解性和加工性。药用赋形剂还影响共同给药药物的吸收、分布、代谢和消除(ADME)过程[1]。

微晶纤维素制备

（1）纤维素是世界上蕴藏量最丰富的天然高分子化合物，生产原料来源于木材、棉花、棉短绒、麦草、稻草、芦苇、麻、桑皮、楮皮和甘蔗渣等。我国由于森林资源不足，纤维素的原料有70%来源于非木材资源。我国针叶材、阔叶材的纤维素平均含量约43-45%；草类茎秆的纤维素平均含量在40%左右。纤维素的工业制法是用亚硫酸盐溶液或碱溶液蒸煮植物原料，主要是除去木素，分别称为亚硫酸盐法和碱法。得到的物料称为亚硫酸盐浆和碱法浆。然后经过漂白进一步除去残留木素，所得漂白浆可用于造纸。再进一步除去半纤维素，就可用作纤维素衍生物的原料。用纤维植物原料与无机酸捣成浆状，制成α-纤维素，再经处理使纤维素作部分解聚，然后再除去非结晶部分并提纯而得。将选好的工业木浆板疏解，然后送入已加1%～10%的盐酸(用量为5%～10%)的反应釜进行升温水解，温度为90～100℃，水解时间0.5～2h，反应结束后经冷却送人中和槽，用液碱调至中性，过滤后滤饼在80～100℃下干燥，最后经粉碎得产品。由木浆或棉花浆制成的纤维素。经漂白处理和机械分散后精制而成。
