Description

Lignosulfonic Acid, Manganese Salt is a water-soluble, organometallic complex derived from lignin, a major component of wood pulp. This compound serves as a versatile and cost-effective source of manganese ions, valued for its catalytic and nutritional properties in various industrial and agricultural processes. It is primarily utilized by manufacturers in the animal feed, agriculture, and chemical synthesis sectors seeking a bio-based, readily available manganese supplement.

Application

• Animal Feed Additive: Acts as an essential trace mineral source of manganese for livestock and poultry nutrition, supporting bone development and enzyme function.
• Agricultural Micronutrient Fertilizer: Used in foliar sprays and soil amendments to correct manganese deficiencies in crops, improving photosynthesis and yield.
• Chemical Catalyst Precursor: Serves as a catalyst or catalyst component in oxidation reactions and organic synthesis due to the manganese ion's redox activity.
• Drilling Fluid Additive: Functions as a thinner and dispersant in water-based drilling muds for oil and gas exploration.
• Concrete Admixture: Employed as a water-reducing agent and set retarder to improve the workability and final strength of concrete mixes.
• Dye Intermediate and Pigment: Used in the production of certain dyes and as a colorant in industrial applications.

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). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent caking and degradation due to moisture absorption.
