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,…
