Product Name:Lignin
English Name:Lignin
CAS No.:8068-03-9
Aliases:Organosolv lignin
Physical Properties:Brown to dark brown powder, amorphous, with an aromatic three-dimensional network structure. The molecular weight is polydisperse, varying with source and functional groups, ranging from about 200 to 10,000. Insoluble in water, soluble in alkaline solutions and certain polar solvents. The molecule contains phenolic hydroxyl, alcoholic hydroxyl, carboxyl and other active groups, capable of condensation and hydrogen bonding, can adsorb on solid particle surfaces, and has a certain chelating ability for metal ions.
Uses:Lignin is widely used as a dispersant, wetting agent and emulsifier in industry. It is used as a dye dispersant in textile printing and dyeing, a mud dispersant in petroleum drilling, as well as an ore flotation agent, pesticide dispersant and metal ion chelating agent.
Technical Specifications:
Purity: ≥99%
Appearance: Brown to dark brown powder
Molecular weight: Approx. 200-10,000, polydisperse
Solubility: Insoluble in water, soluble in alkaline solutions
Active groups: Contains phenolic hydroxyl, alcoholic hydroxyl, carboxyl, etc.
