lignin properties
Different pulping processes and lignin extraction method to obtain the main physical and chemical properties include the following: 1.Color of lignin Original lignin is a white or nearly colorless material. We see the color of lignin, in isolation, caused by the preparation process. With the separation of the different preparation methods, showing different shades. Acid…

How to extract lignin
Two method to extract lignin One is the plant body other than the components are dissolved out of lignin, lignin as an insoluble component separated by filtration; typical example of this approach is the acid hydrolysis of wood, the cellulose is hydrolyzed into glucose, the hydrolysis of lignin residues are separation. Available 65% to 72%…

Calcium Lignosulfonate Manufacturering Process
Calcium lignosulfonate is obtained from soft wood processed in sulfite pulping method for producing paper. They small pieces of softwood is put into reaction tank to react with acidic calcium bisulfite solution for 5-6 hours under the temperature of 130 degree Centigrade. During the process the bisulfite ions reacted with native lignin to for sulfonated lignin,…
