desulfonation

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

对亚硫盐-甲醛-蒽醌制浆法（SFP）副产品木质素磺盐在碱性高温条件下进行了脱磺工究。

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

所测得烷基苯磺均相对分子质量与气相色谱法相比,相对偏差不大于0.1%。
