采用水热法对木质素进行增溶和功能化处理。SAL在碱性介质中，特别是在氢氧化钠溶液中，易于溶解。反应产物的可溶性部分（S-HSAL）在中性pH下溶解，红外光谱分析表明，SAL在反应过程中引入了亲水基团。磺化后S-HSAL的分散性提高，是石膏浆体的有效分散剂。
Sulfuric acid lignin (SAL), which is formed as a by-product during the production of bioethanol from woody biomass, was solubilized and functionalized by hydrothermal reaction. SAL could be easily dissolved in an alkaline medium, especially sodium hydroxide solution, by this reaction. The soluble part of the reaction products (S-HSAL) could be dissolved at neutral pH. IR spectrometric analysis of SAL revealed that hydrophilic groups were introduced in it during the reaction. The dispersibility of S-HSAL was increased by sulfonation (SS–HSAL), and it was found to be an effective dispersant for gypsum paste.
