The difference between Lignin and Lignosulphonate

Lignosulfonate is one of the derivatives of lignin. they are different  in origin,chemical layout and physical properties. Lignosulfonate primary come from the sulfite process of paper pulping “black liquor”  by the sulfite process, first of the separation from the“black liquor” is the sodium lignosulphonate and calcium lignosulphonate. Lignin was one of the three major components of the wood itself (the other components is cellulose and hemicellulose), is a kind of natural polymer, Content in plants usually is Cellulose >lignin >hemicellulose. lignin could be obtained from the plants  with many solutions , Contains organic solvent to obtain, lye acquisition, anthraquinone  process, etc. For lignin with sulfite method, and they will get the lignosulfonate. The biggest differences between lignin and lignosulfonate is the lignin insoluble in water, while the lignosulfonate soluble in water easily. Lignosulfonate absorb the moisture easier in the air. The application of the Lignin Can be made into lignin and phenolic resin, polyurethane resin lignin, lignin chelating resin, etc. Lignin can be made into rubber reinforcing agent.Lignin can be made into oilfield chemicals.For example: Drilling mud additives, Oil surfactant, etcLignin can be used as building materials additives.like water reducing agent for concrete.Lignin can be used as adhesive in wood industry.Lignin can be used as surface active agent and dye dispersants in light industry.High quality of lignin can be used as coal water slurry additive.

lignin & Lignosulfonate

Lignin is exist with cellulose in wood, straw and other plant working as binder of cells walls,so naturally has good binding capacity. These is a lot of ways to separate the lignin and cellulose. Most easily way is popular used in China ,they just treated NaOH to separate lignin and cellulose .Cellulose is used as […]

Lignin and Cellulose

To solve cellulose purification process of the environmental pollution problems caused , Beijing Dream Fox Yutong fiber research and development center has successfully developed a zero pollution, zero emissions , high utilization of the ” green energy biomass organic component separation process technology .” It is understood that this technology after full trial , from […]

Difference between lignin and lignosulfonate

Lignosulfonate is one of lignin derivatives. It is the source and lignin, chemical structures and physical properties are different. Lignosulfonate mainly from the sulfite pulping process resulting “black liquor”, separated from the black liquor extracted, mainly ligno sodium or calcium lignosulphonate. The three components of wood lignin itself (the other two are the cellulose and […]
