Although lignosulfonate has been widely used as dye dispersant, it has some disadvantages. On the one hand, thecolorless catecholic structure in lignin is easy to oxidize toquinonoid structure in…

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…

Lignosulfonate used in Cattle Feed Eighteen Hereford steers, individually housed, were fed diets containing 0,80000 and 120 000 mg/kg of an ammoniated spent sulphite liquor （50% DM）, containing 57%…

Lignosulphonate absorption In its recent assessment of calcium lignosulphonate, the EFSA ANS Panel (2010) concluded that: “The in vitro studies indicate that the low transepithelial transport measured in Caco2…

1.Lignosulfonate Manufacturing process Lignosulphonate is produced from the sulphite pulping of lignocellulosic biomasses. The cellulose rich fibres are delignified with sulphite or bisulphite, depending on the operational pH. One…

1. Introduction Lignosulphonates are currently authorised for use as technological additives (functional groups: binders, anti-caking agents and coagulants) in feedingstuffs for all species and categories of animals, with no…

Lignosulphonates are amorphous branched polymers of lignin, containing sulphonated covalently linked phenyl propane monomers, produced from the sulphite pulping of lignocellulosic biomasses. The calcium lignosulphonate, sodium lignosulphonate and magnesium…

Sodium lignosulfonate water-reducing agent by using pulping black liquor, which has the following preparation technological steps: after the thin pulping black liquor is concentrated into dark black liquor of…

The spent liquor of the sulfite pulping process is dilute and contains other impurities; therefore, lignosulfonates should be separated from the spent liquor for increased commercial value. Because lignosulfonates…
