Ligninesulfonic acid sodium salt - Preparation method
Open Data Verified Data
The acidic sulfite pulp wastewater from wood is precipitated by lime milk to convert and grade reducing sugars, and then filtered; After refining the filter cake, add acid to dissolve it, and then filter it. The filtrate is converted into sodium salt by sodium carbonate, evaporated, and dried by spray.
