Pure lignin is black brown powder not water soluble,with pH4-7.Petroleum is the lifeblood of the chemical industry. Lignin is a wood component that is proving to be a particularly promising resource,It is the raw material for basic chemicals and is used to produce a tremendous wealth of products.
Lignin is a class of complex organic polymers that form key structural materials in the support tissues of vascular plants and some algae. Lignins are particularly important in the formation of cell walls, especially in wood and bark, because they lend rigidity and do not rot easily. Chemically, lignins are cross-linked phenolic polymers.
