Production and Application of Lignosulfonates and Sulfonated

Kraft lignin is separated from wood with the help of NaOH and Na 2 S. 13 Lignins from sulfite pulping processes are denoted as lignosulfonates, and are produced by using sulfurous acid and/or a sulfite salt containing magnesium, calcium, sodium, or ammonium at varying pH levels. 2, 14 Currently, lignosulfonates account for 90 % of the total mark...

Lignosulfonates are bio-based surfactants and specialty chemicals, which are generated by breaking the near-infinite lignin network during sulfite pulping of wood. Due to their amphiphilic nature, lignosulfonates are used in manifold applications such as plasticizer, dispersant, and stabilizer formulations.

On the effect of calcium lignosulfonate on the rheology

A sugar-reduced softwood calcium lignosulfonate (LSs) was used as plasticizer. Its mass weighted molecular weight (M w), as measured with gel permeation chromatography (GPC), was 29,000 g/mol and the number weighted molecular weight (M n) was 2100 g/mol, giving broad molar-mass dispersity (? M) equal to 13.8.

Preparation Lignosulfonates Lignosulfonates are recovered from the spent pulping liquids (red or brown liquor) from sulfite pulping. Ultrafiltration can also be used to separate lignosulfonates from the spent pulping liquid. [1] A list of CAS numbers for the various metal salts of lignosulfonate is available. [4]

CALCIUM LIGNOSULFONATE (40-65) - Food and Agriculture

Calcium lignosulfonate (40-65) is an amorphous light-yellow-brown powder obtained from the sulfite pulping of softwood. The organic framework of the additive is a sulfonated random polymer of three aromatic alcohols: coniferyl alcohol, p-coumaryl alcohol, and sinapyl alcohol, of which coniferyl alcohol is the principle unit.
