Straw Pulp Lignin Sodium Lignosulfonate Water Reducer Early Strength Agent CAS 8068-05-1

Ligninsulfonate SF-1 CAS 8068-05-1 Concrete Admixture pH 9-10 Water Reducing Agent Product Description:

Sodium lignosulfonate is an inorganic substance, chemical formula for C20H24Na2O10S2. Sodium lignosulfonate can be used as admixture of polymer and concrete, which has the advantages of low cost and environmental friendliness. Lignin is a natural polymer, second only to cellulose and chitin in content. One of its most extensive uses is to convert it to lignosulfonates, including sodium lignosulfonate, by sulfonation modification. (sodium Ligninsulfonate).

Molecular Structure Of Lignin Monomer:

Lignin is a kind of complex phenolic polymer formed by three alcohol monomers (p-coumarol, coniferol, myucinol).
Lignin is one of the components that make up the cell wall of plants and has the function of connecting cells. From the botanical point of view, lignin is surrounded in tracheids, vessels and wood fibers and other fiber bundle cells and thick-walled cells outside the material, and make these cells have specific color reaction droplets, that is, red) material; From a chemical point of view, lignin is a polymer randomly polymerized by highly substituted propane units. Together with cellulose and hemicellulose, it forms the main component of plant skeleton, second only to cellulose in quantity. Lignin fills cellulose framework to enhance the mechanical strength of plant body, which is conducive to water transport and resistance to the invasion of external environment. Lignin is abundant in hard tissues such as wood, but rarely found in vegetables. It is found in beans, wheat bran and the seed parts of strawberries and raspberries. Its job is to absorb bile acids, the main component of bile, and expel them from the body. In addition, although the details are still unknown, the structure of lignin is very similar to that of polyphenols, so lignin and polyphenols should be closely related. In short, both have good effects on the body. Due to the presence of aromatic groups, phenols, alcohols, carbon based conjugate double bonds and other groups in the molecular structure of lignin, many chemical reactions such as oxidation, reduction, hydrolysis, alcoholysis, acidolysis, carboxyl, phthalide, sulfonation, alkylation, halogenation, nitrification, condensation or graft copolymerization can be carried out. Among them, oxidation, phthalide, sulfonation, polycondensation and graft copolymerization have played a particularly important role in the application of lignin, and are also an important way to expand its application. In this process, the sulfonation reaction is the basis and premise of the application of lignin. So far, the application of lignin is mostly used in the form of lignosulfonate. In sulphite pulp production process, it is because of sulfite solution with wood powder in lignin sulfonation reaction happened originally, the introduction of sulfonic group, increased the hydrophilicity, and the lignin sulfonate further hydrolysis reaction in acidic cooking liquor, with lignin depolymerization of hemicellulose happen, so that the lignin sulfonate dissolution, The separation of lignin, cellulose and hemicellulose was realized, and the pulp was obtained. Meanwhile, the application of lignin became possible.
