Lignin is the largest reservoir of aromatic compounds on earth and has great potential to be used in many industrial applications. Alternative methods to produce lignosulfonates from spent sulfite pulping […]
Sodium Lignosulfonate and its Uses
Sodium lignosulfonate (lignosulfonic acid, sodium salt) is used in the food industry as a de-foaming agent for paper production and in adhesives for items that come in contact with food. […]
Calcium Lignosulfonate Manufacturing
An insoluble basic calcium lignosulfonate salt has been produced heretofore by treating the waste liquor from the calcium-base acid sulfite process of wood pulping with an excess of lime. Before […]
Sulfonated lignin from kraft black liquor
The sulfite pulping process has many environmental issues,and thus, only a small portion of market pulp (less than 10%,roughly 7 million tons) is produced by the sulfite pulping process. In […]
Lignosulfonate and kraft lignin
The world’s most abundant renewable resource is biomass (wood and nonwood), of which the three main components are cellulose, hemicellulose, and lignin. In woody biomass, cellulose is the most abundant […]
Sodium lignosulfonate superplasticizer
The effects of sodium lignosulfonate superplasticizer on the hydration of Portland cement Type V have been investigated by XRD and FTIR techniques. The results of these studies indicate that the […]
