1.The water reducing agent of cement was prepared via sulfonation of semi-chemical pulping black liquor.
2.A study on the sulfonation condition of lignin and paper-making black liquor was made, and the conditions were determined.
3.The sulfonation could take place in an unclosed system.
5.The lignosulfonate water reducing agent was prepared via oxidation and sulfonation of wheat straw alkali lignin.
6.In this paper we studied out a heterogeneous sulfonation method for preparing sulfonated polysulfone with low sulfonation values.
7.The sulfonation technology of the liquid sulfur trioxide was also reviewed.
