desulfonation

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

亚硫酸盐-甲醛-蒽醌制浆法（SFP）副产品木质素酸盐在碱性高温条件下进行了艺研究。

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