High Quality 99% Purity of Calcium lignosulfonate CAS NO 8061-52-7 in bulk quantity

Chemical Identity: Calcium Lignosulfonate (CAS No. 8061-52-7) Description: Calcium lignosulfonate is a water-soluble lignin derivative obtained from the sulfite pulping process in the paper industry. It is commonly used as a dispersant, binder, and plasticizer in various industrial applications.

Physical Properties: Description: Calcium lignosulfonate typically appears as a brown to dark brown powder or granules. It is highly soluble in water, forming brown solutions. Its solubility and viscosity may vary depending on the degree of sulfonation and molecular weight.

Chemical Structure: Description: The chemical structure of calcium lignosulfonate consists of lignin molecules that have been sulfonated during the pulping process. The sulfonation introduces sulfonate groups (-SO3Ca) onto the lignin backbone, imparting water solubility and anionic character. Calcium ions (Ca2+) may also be present as counterions.

Production Method: Description: Calcium lignosulfonate is produced as a byproduct of the sulfite pulping process used to extract cellulose fibers from wood. Lignin, a natural polymer in wood, undergoes sulfonation with calcium sulfite and calcium hydroxide, yielding calcium lignosulfonate along with cellulose pulp.

Applications in Industry: Description: Calcium lignosulfonate finds widespread applications in various industries, including construction, agriculture, ceramics, and textiles. It is used as a dispersant in concrete and gypsum formulations, a binder in pelletized feeds and animal feed additives, and a dust suppressant in road construction.

Construction Applications: Description: In the construction industry, calcium lignosulfonate is utilized as a plasticizer and water reducer in concrete admixtures. It improves workability, reduces water content, and enhances the strength and durability of concrete mixes.

Agricultural Applications: Description: Calcium lignosulfonate is used in agriculture as a dispersant and binder in pesticide formulations, as well as a soil conditioner and plant growth stimulant. It improves the dispersion and uptake of agrochemicals and enhances soil structure and water retention.

Environmental Impact: Description: Calcium lignosulfonate is considered environmentally friendly and biodegradable. It poses minimal risks to aquatic organisms and ecosystems when used according to recommended guidelines. However, excessive runoff into water bodies should be avoided.

Regulatory Status: Description: Calcium lignosulfonate is generally recognized as safe (GRAS) for use in food and feed applications by regulatory agencies such as the FDA in the United States and the European Food Safety Authority (EFSA) in the European Union. It is also approved for various industrial uses.

Safety Precautions: Description: While calcium lignosulfonate is generally considered safe, proper handling procedures should be followed to minimize dust inhalation and skin contact. Use of gloves, goggles, and a dust mask is recommended when handling powdered forms. Store calcium lignosulfonate in a dry, well-ventilated area away from sources of heat and ignition.
