What is Sodium Lignosulfonate?
Sodium lignosulfonate is also known as sulfite lignin. It is a heterogeneous anionic polyelectrolyte with different molecular weights and different structures, that is, polydispersity. The solid product is a light brown free-flowing powder that is hygroscopic. It is easily soluble in water, but insoluble in ethanol, acetone and other common organic solvents. The aqueous solution is brown to black with colloidal properties, and the viscosity of the solution increases with the concentration. It is a by-product of acid sulfite cooking and pulping in pulp production, and its content in pulping waste liquid accounts for about 42% to 55%.
During preparation, lime milk is added to the waste liquid of sulfite slurry to form basic calcium lignosulfonate precipitation, which is then separated and acidified by adding sulfuric acid to the precipitation filter cake, and then sodium carbonate is added to replace the base to make it. The calcium salt becomes sodium salt, and finally, the finished product is obtained by evaporation and drying. Sodium lignosulfonate has the functions of dispersing, binding, complexing and emulsifying-stabilizing, and is widely used in feed processing, mining, oil drilling, pesticides, rubber, printing and dyeing, leather and cement and concrete production.
In water treatment, this product can be used as scale inhibitor, dispersant and corrosion inhibitor for cooling water; it can be used as dispersant scale inhibitor in boiler water, with good thermal stability, even at 250℃, it can still maintain good dispersion performance. In addition, it is also widely used in the manufacture of industrial cleaning agents, asphalt emulsion preparation, lead-acid batteries and various ceramic products.
Sodium Lignosulfonate Uses
- Sodium lignosulfonate is used as a dispersant for dyes, wax lotion, pigments, water treatment and cleaning agents. Ceramic adhesive, dispersant in pigment and water treatment, stabilizer of wax and O/W lotion, tanning agent.
- Salt lignosulfonate (sodium lignosulfonate) is used as defoamer for paper manufacturing as well as adhesive for write-ups in contact with food in the food sector. It has antiseptic buildings and also can be utilized as a component of animal feed. It is likewise utilized in design, porcelains, mineral powder, chemical market, fabric market (natural leather), metallurgy industry, petroleum industry, fire resistant products, rubber vulcanization, and also organic polymerization.

Application of Sodium Lignosulfonate
Lignosulfonates, including sodium lignosulfonates, have surface physicochemical properties such as dispersion, emulsification, solubilization, and adsorption due to their special structures, and their modified products have been used as surfactants to some extent.
Utilize the lignosulfonate-containing waste liquor from the acid pulping process to help enhance oil recovery, and has applied for a patent. Research workers at home and abroad have done a lot of research to modify lignosulfonate by various methods. Modified products are compounded with other surfactants to form a variety of oilfield chemicals. Among the 16 categories and 262 varieties of oilfield chemicals used in the petroleum industry, there are as many as 5 categories and 39 varieties of lignosulfonates, which are widely used as viscosity reducers for heavy oil, sacrificial agents for tertiary oil recovery, Water adjustment and profile plugging agent, drilling fluid treatment agent, etc.
The lignosulfonate is modified by tannin extract and formaldehyde, and then chelated with ferrous ion to obtain a green and environment-friendly chromium-free drilling diluent. The chelation of ferrous ions and polymer surfactants reduces the surface Zeta potential of bentonite, and at the same time, the chelation system has greater steric hindrance, which makes the bentonite particle aggregates have greater movement space and freedom, thereby reducing the The viscosity and gel strength of the slurry, high temperature resistance and dilution are greatly improved compared with lignosulfonate.
Concrete water reducing agent is currently the application field with the largest demand for lignosulfonate and its modified products.
The series of lignosulfonate concrete water reducing agents meet the national standard of high-efficiency retarding water reducing agents. They have excellent properties such as high water reducing performance, low slump loss, high strength, and retarding setting. market competitiveness. Under acidic conditions, sodium lignosulfonate is oxidatively modified with a higher amount of hydrogen peroxide, and the water-reducing performance of the modified lignosulfonate concrete water reducing agent is improved by 68%. At the same time, the mechanism of action of lignosulfonate and cement as concrete water reducing agent has also been extensively studied.
It is proved by infrared spectroscopy that the addition of sodium lignosulfonate prolongs the induction period of cement hydration and inhibits the process of hydration reaction, and proposes a “charge-controlled reaction model” in which sodium lignosulfonate inhibits hydration. The calcium ions entering the solution in the initial hydration stage form a bilayer on the surface of the cement particles with anionic charges, and then quickly form a trilayer structure with the anion molecules generated by the ionization of sodium lignosulfonate, thereby inhibiting the further hydration of the cement.
Multi-walled carbon nanotubes were functionalized by a non-covalent approach using lignosulfonates. The lignosulfonate-functionalized carbon nanotubes can be well dispersed in water with a solubility up to 1.5 mg/mL. The interaction between lignosulfonate and multi-walled carbon nanotubes occurs mainly through π-π conjugation and hydrophobic bonds. Functionalized carbon nanotubes have a variety of anionic groups due to the attachment of lignosulfonate molecules, which can act as anchor centers for quantum sites.
Using sodium lignosulfonate to functionalize multi-wall carbon nanotubes, the effect of sodium lignosulfonate on the dispersion and electrical conductivity of multi-wall carbon nanotubes was investigated. It was found that a small amount of sodium lignosulfonate can functionalize multi-walled carbon nanotubes with good stability, while an excess of sodium lignosulfonate has little effect on improving the solubility of multi-walled carbon nanotubes, but reduces the its electrical conductivity.
The pulping properties of sodium lignosulfonate and calcium lignosulfonate were studied, and it was found that the dispersibility of sodium lignosulfonate was significantly better than that of calcium lignosulfonate. According to the analysis, the reason is that calcium ion has good complexation with sulfonate and hydroxyl group, so that part of calcium lignosulfonate does not dissociate. In addition, this strong complexation reduces the saturated adsorption of calcium lignosulfonate on the surface of coal particles, reducing the potential of the coal surface, resulting in the electrostatic repulsion and steric hindrance of calcium lignosulfonate than lignin Sodium sulfonate is small, so the dispersibility is poor.
At the same time, since the coal particles in the slurry of calcium lignosulfonate form a stable spatial structure through the strong complexation between sulfonate and calcium ions and high-valent metal ions in coal, while adding sodium lignosulfonate In the slurry of , the complexation is weak and cannot form a stable spatial structure, so the stability of sodium lignosulfonate is slightly worse than that of calcium lignosulfonate. Under the condition that the slurry concentration is 60% and 61%, and the additive amount is 0.6% to 1.4%, the viscosity of the slurry is 800 mPa.s with both additives.
The conductive polymer PANI was doped with sodium lignosulfonate, calcium lignosulfonate and magnesium lignosulfonate respectively, and the conductivity, solubility and thermal stability of PANI were improved. In the presence of lignosulfonate, using ammonium persulfate as initiator and aniline as raw material, conductive hollow nano-microspheres were synthesized by one-step polymerization. Adjusting the polymerization temperature and time can optimally control the morphological structure and electrochemical performance. Using lignosulfonate as dispersant and vinylaniline as raw material, a novel polyvinylaniline/lignosulfonate composite was synthesized by in-situ polymerization.
PNA-LS nitrogen-containing carbon materials were obtained by pyrolysis at 300-1200 ℃, and the structure and properties of PNA-LS carbon materials were characterized by analysis. The results show that the morphological structure and properties of PNA-LS depend on the ratio of LS and NA. When the ratio is equal to 2.5∶97.5, the particle size of PNA-LS carbon nanospheres is 1300 nm. The average particle size of the microspheres was 820 nm. PNA-LS has a mild preparation method, low cost, enhanced solubility and electrical conductivity, and has great application potential in the fields of conductive nano-films and anti-corrosion. The 820-nanometer carbon nanospheres prepared at 800°C have nitrogen atoms and a high specific surface area, which can be expected to be applied to electrodes of lithium-ion secondary batteries.
Application Principle of Sodium Lignosulfonate
The number of carbon chains varies greatly depending on the material from which lignin is extracted. Some are suitable for fertilizer production, and some are suitable for pesticide additives. It contains a variety of active functions, dispersibility and chelation, and it is easy to combine with metal elements to form a chelated state, improve the physical and chemical properties of metal nutrient elements, save costs and improve efficiency. The adsorption and slow-release properties of lignin can better maintain the effectiveness of chemical fertilizers and can make it slowly release, and it is a good slow-release material for organic compound fertilizers. Lignin is a polycyclic macromolecular organic compound containing many negatively charged groups, which has a strong affinity for high-valent metal ions in soil.
Sodium lignosulfonate can also be used for pesticide processing. Lignin has a large specific surface area and contains a variety of active groups, which can be used as a slow release agent for pesticides.
There are differences in structure between lignin in plants and isolated lignin. The newly generated cell wall of plant cell division is thin and rich in acidic polysaccharides such as pectin, and gradually generates cellulose and hemicellulose, and the cells differentiate into various unique xylem cells (wood fibers, tracheids, and vessels, etc.), when formed When the secondary wall is in the S1 layer, lignin begins to form from the corners of the primary wall, and this phenomenon is generally called lignification. With the maturation of plant tissues, lignification develops to the intercellular layer, primary wall and secondary wall. Lignin is gradually deposited in and between the cell walls to bond cells together. During the lignification process of plant cell walls, lignin is formed. The infiltration of lignin into the cell wall increases the hardness of the cell wall, promotes the formation of mechanical tissues, and enhances the mechanical strength and load-bearing capacity of plant cells and tissues; lignin makes the cell wall hydrophobic, making the plant cells impermeable to water, which is a good source of water, minerals. The long-distance transportation of substances and organic matter in plants provides a reliable guarantee; the infiltration of lignin into the cell wall objectively forms a physical barrier, effectively preventing the invasion of various plant pathogens; preventing the conduction molecules in the xylem from transporting water Infiltrate out, while enabling terrestrial plants to survive in a relatively dry environment, enhancing the plant’s disease resistance. Lignin acts as a binding agent for cellulose, hemicellulose and inorganic salts (mainly silicates) in plants.
Factors affecting the decomposition of lignin are soil pH, moisture and climatic conditions. Other factors such as nitrogen availability and soil mineralogy also play a role. Among them, the adsorption of Fe and Al oxides to lignin can reduce the decomposition of lignin.
