• Lignosulfonates show good water solubility in water over the entire pH range but are insoluble in many organic solvents. /Ligninsulfonate salts/
• ... ligninsulfonates must be easily soluble and the dispersions stable at higher temperature. These properties are achieved by suitable purification and chemical treatment of the crude product. /Ligninsulfonate salts/

• Worldwide, the single largest use of lignosulfonates is as water reducers for concrete. ... Additional large-volume uses of lignosulfonates include animal feed pellet binders, dispersants for gypsum board manufacture, thinners/fluid loss control agents for drilling muds, dispersants/grinding aids for cement manufacture, binders for granulated fertilizers and in dust control applications, particularly road dust abatement, and other specialty dust control applications. /Lignosulfonates/
• Ligninsulfonic acids are made from native lignin. Two different starting materials are available: (1) lignin made from sulfite pulping and (2) lignin made from alkaline (kraft) pulping of wood. In the first case, the sulfite waste liquor is purified and marketed as a liquid or a solid. Lignin from kraft pulping is first purified and then sulfonated.
• Various methods have been developed for isolating and purifying lignosulfonates from spent pulping liquors. One of the earliest and most widely used industrial processes is the Howard process, where calcium lignosulfonates are precipitated from spent pulping liquor by addition of excess lime. Lignin recoveries of 90-95% are obtainable through this process. Other methods used industrially include ultrafiltration and ion-exclusion, which uses ion-exchange resins to separate lignin from sugars. Laboratory methods for

• Industrial lignins are by-products of the pulp and paper industry. Lignosulfonate [8062-15-5], derived from sulfite pulping of wood, and kraft lignin [8068-05-1], derived from kraft pulping, are the principal commercially available lignin types.
