Description

Chlorolignin CAS NO 8068-02-8 is a chemically modified lignin derivative, produced by the chlorination of lignin, a major component of wood. This modification enhances its properties, making it a valuable functional additive and intermediate for various industrial processes. It is primarily utilized in sectors such as construction, agriculture, and chemical manufacturing where its binding, dispersing, and chelating characteristics are essential.

Application

• Concrete Admixtures: Acts as a water-reducing agent and plasticizer to improve workability and strength of concrete mixes.
• Oil Well Drilling Fluids: Serves as a deflocculant and fluid loss control additive in drilling mud formulations.
• Agricultural Dispersants: Used in pesticide and fertilizer formulations to enhance stability and dispersion of active ingredients.
• Dye & Pigment Industry: Functions as a dispersing agent for dyes and pigments, improving color uniformity and stability.
• Leather Tanning: Employed as a tanning auxiliary to improve the penetration and fixation of tanning agents.
• Ceramic & Refractory Binders: Used as an organic binder to provide green strength to ceramic and refractory shapes before firing.
• Waste Water Treatment: Acts as a flocculant aid and chelating agent for the removal of heavy metals and organic contaminants.
• Foundry Sand Binders: Serves as a core binder in metal casting processes to provide mold strength.

Quality Control

Our Chlorolignin is produced under strict quality management protocols. Each batch undergoes rigorous testing to ensure consistent performance and meets the specifications required for its target applications. Certificates of Analysis (COA) documenting key parameters such as active content, chlorine content, and solubility are available upon request to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent moisture absorption, which can affect product performance.
