0011326196 application field and working principle

0011326196, also known as lignin sulfonate, is a linear, sulfonated, water-soluble polymers of phenolic compounds derived from lignin, a non-structural component of wood. It has a wide range of applications , from improving soil fertility to water treatment. Its working principle is closer to that of nonionic surfactants than that of anionic surfactants.

History

Lignin was originally discovered in 1812 by the German botanist M.H. Lindsay, and it wasn’t until 1906 that a process was developed to isolate and purify lignin for industrial use. In 1957, the first lignosulfonates were produced in a pilot plant in Austria. Lignin sulfonates were developed as an alternative to petroleum-based surfactants because of their sustainability and biodegradability.

Application Field

Lignin sulfonates are primarily used as a dust suppressant, to reduce surface runoff, and dry particle separation in agricultural practices – although their uses are far more varied. Other applications include:

• Diesel fuel oil additives
• Cement and concrete additives
• Rolling stock lubrication
• Seeding and soil conditioning
• A drilling lubricant for horizontal directional drilling
• A flotation agent in mineral processing processes
• A dispersing agent for paints, dyes and pigments
• A corrosion inhibitor for cooling towers
• A de-icing agent for roads, runways and parking lots
• A dispersant for clay- and wax-based lubricants

Working Principle

Lignin sulfonates are classified as nonionic surfactants - meaning they do not have a charge and do not interact with either an anionic (-)or cationic (+) ions in solution. Unlike anionic surfactants that contain ionic head groups, lignin sulfonates have chemically non-reactive head groups, leading to higher water solubility. These nonionic properties also allow them to interact with both anionic and cationic surface and interface active species, giving lignin sulfonates a much wider range of applications than anionic surfactants.

Environmental Impact

Lignin sulfonates are highly biodegradable and environmental friendly. They are not toxic and have less than 1% of the negative impacts associated with chlorine-based surfactants. In addition, they are designed not to accumulate and cause long term damage to natural ecosystems.

Conclusion

0011326196, or lignin sulfonate, is an effective and environmentally friendly substitute for petroleum-based surfactants. It has a wide range of applications from dust suppression to Fuel additives and flotation agent in mineral processing processes. Its working principle is that of nonionic surfactants rather than anionic, meaning that it interacts with both cationic and anionic species. Lignin sulfonate is also highly biodegradable and environmentally friendly.
