Desulfonation of SFP lignosulfonate was studied in this paper under alkaline and high temperature and pressure.

亚硫酸盐--醌制浆法（SFP）的副产品木质素磺酸盐在碱性高温条件进行了脱磺工艺的研究。

This method was compared with that of desulfonation GC and the relative deviation of LAS average molecular weight is less than 0.1%.

所测得的烷基苯磺酸的平分子质量与气色谱法比,偏差不大于0.1%。
