摘要
以芦苇为原料,常压、蒸煮时间为1.5h,在乙醇(70%)、催化剂(7%)和液固比(6∶1)条件下,得浆纯度较高,所得木素仍是由苯及其衍生物构成的大分子,所得木素的分子量远大于一般碱木素,分布范围较窄。
With reed as raw material, under the normal air-pressure, cooking time of 1.5h, ethanol (70%), catalyzer (7%) and liquid-to-solid ratio of 6:1, the obtained pulp is of higher purity. The structure of lignin obtained is the macromolecule composed of benzene and its derivatives, and the lignin's molecular weight, with a narrow distribution range, is greatly larger than the alkaline lignin's.
