Lignosulfonate Lignin brown powder HS 3804000090
Lignin
Lignin is complex organic polymers of propyl phenol units,namely,coniferyl alcohol and sinapyl alcohol,with a minor quantity of p-coumaryl alcohol The complex of these components is cross-linked together through carbon-carbonesterand linkages.
Lianins are particularly important in the formation of cell walls,especially in wood and bark,because they lend rigidity and do not rot easily. As a renewable raw material,lignin has the potential to extend to any product currently sourced from petrochemical substances.
Lignin is an important constituent of the structural framework inplants formingpart of the primary elements of the cell wall. By viewing the point of evolution. lianin has been attributed as the terrestriavariation that allows sianificant vertical growth.
As an important part of the cell.lianin provides support to plant bycommunicatina riaidity to the celwalThe plant resists ecoloaica stresses because
of building blocks of cell wall.
Lignin provides rigidity to the plants but in aggregation with the hetero-polysaccharides,itenhances flexibility which is central for suitable response to dynamic loads from wind and snow.Additionally, lignin changes the polysaccharide network to make it resistant to foreign organisms.
Lianin helps in the protection of woody tissues from microbial and fungal attack covering the carbohydrate structure, causing reduced availability of enzymes for hydrolysis.Partial solubility and complexity of the lignin makes it tough for degradation by microorganisms
Still, with the diversity of associations,harmful organisms for woodrequire the breakage of aryl carbon bonds and aryl bonds requiring increasing the cost of production of specific enzymes or developing non-specific pathways for delianification. Additionally, lignin is less hydrophilic in nature than the polysaccharides helping to alter the permeability of cell wall by sealing it and enabling water transport through the vascular tissue.
The aromaticity of lignin lends itself to improvina the heat stability ofwoodLianin nature has been broken with separated technical lignin. Chanaina it into carbon fiber by using controlled increased temperature. While lignin is more heat stable but the structure of lianin is areatly obstructed by the
thermal chanae and scientists should be advised that lianin structure can alter by processina at hiaher temperatures used in the production some thermoplastic materials.
This type of modification comprised of polymerization, loss of hydroxyl group and synthesis of new acidic groups
