| 摘 要： | 研究了木素磺酸盐丙／乙氧基化改性产物的表面活性，指出了不同结构衍生物表面活性的差异。结果表明，LS－PO结构的衍生物有较好的润湿性；LS－PO－EO结构产物有较好的乳化性和在水介质中的分散性；而LS－PO－EP－PO结构的衍生物在非水介质中有很强的分散性能。

| Abstract: | The surfactancy of lignosulfonate derivatives about proplene oxide adduct and ethoxylation has been studied.After reaction with PO,the ability for reducing the surface tension of water solution was improved.With controlling the amount and chain length of PO or EO,we can make the target products with better lipophilicity and wider adjustable quality.The results suggest that the derivative with LS PO structure has better wettability.The LS PO EO structural products have better emulsification and dispersive property in water medium.The derivative with LS PO EO PO structure has better dispersive property in oil phase. |
