What is Calcium Lignosulfonate? Calcium lignosulfonate (Calcium Lignosulfonate)belongs to the class of organic compounds known as lignans, neolignans and related compounds. Calcium lignosulfonate is an extremely weak basic (essentially neutral) compound (based on its pKa). Calcium lignosulfonate is an odorless tasting compound. Calcium Lignosulfonate Structure These are plant products of low molecular weight formed primarily…

The two isolated biorefinery lignosulfonates (LSs), Na-LS and Ca-LS, both had a molecular weight of approximately 9000 Da. Fundamental lignin properties such as chemical structure, functional groups were analyzed. The two LSs showed slightly better to equal performance in modifying CWS rheology than a commercial dispersant naphthalene sulfonate formaldehyde condensate (FDN), despite they were less sulfonated…

The only lignin products obtained from a pulping process that have found a vast range of applications up to now are lignosulfonates. These are non-hazardous materials with excellent properties that are used as binders, emulsifiers and dispersants for a great variety of materials. As inexpensive components in binders, lignosulfonates are commonly used for commodities like coal briquettes, ceramics,briquetting of mineral dust, and the production of plywood or…

Lignosulfonates are obtained from sulfite pulping processes wherein cellulose is extracted from wood in the pulp industry. The so-called sulfite pulping process involves mixing sulfur dioxide (SO2) with an aqueous solution of base to generate the raw liquor for cooking the wood. In water, the sulfur dioxide forms sulfurous acid (H2SO3), which degrades and eventually sulfonates the lignin by…
