摘　　要：采用木质素磺酸盐作为主要合成原料,通过磺化、缩合等合成手段对其进行改性实验研究,确定了最优的实验方案。实验结果表明:所合成的木质素磺酸盐改性添加剂不仅性能优于萘系和脂肪族系添加剂,而且价格也大幅降低,具有较强的市场竞争力。Using lignosulfonate as main raw material, the experimental research on a modified additive for gasifying coal water mixture through sulfonation and condensation was introduced in this paper, and the optimum experiment condition was determined. The study result showed that the performance of modified lignosulfonate was much better than the naphthalene and aliphatic series, moreover, the price of the modified additive was reduced by more than 20%, which meant a good market competitiveness.
