摘　　要：实验在常压下将黑液酸化、过滤后直接用于制备木素磺酸盐,旨在为中小型企业提供一种经济可行的黑液资源化途径。该工艺取消了木素的纯化过程,流程短而且设备简单、成本低,但磺化产率偏低。本文主要讨论了反应时间、温度、磺化剂加入量和pH对磺化产率的影响。Making lignosulfonate-sodium with the black liquor after acidification and filtration under normal pressure, is a feasible way for the medium and small plants to prevent water pollution and make use of the resource in black liquor. This technique canceled the process of lignin purification, the equipment is simple and the cost is low, but the lignosulfonate rate is a bit low. This paper analyzed the influences of reaction time, temperature, Na 2SO 3 and pH on its production rate.
