Description

Cobalt Acetate CAS NO 71-48-7 is an inorganic salt of cobalt and acetic acid, typically appearing as a reddish-violet crystalline solid. This versatile compound serves as a crucial source of cobalt ions, valued for its catalytic and color-imparting properties across several high-value industries. It is an essential raw material for manufacturers in the chemical, ceramics, and surface treatment sectors seeking consistent quality and reliable supply.

Application

• Catalyst Production: A key precursor in the synthesis of catalysts for the petrochemical industry, including those used in oxidation and hydroformylation reactions.
• Surface Treatment & Electroplating: Used in electroplating baths to deposit cobalt and cobalt alloy coatings, providing wear resistance and magnetic properties.
• Pigments & Dyes: Acts as a colorant in the production of ceramics, glass, and inks, delivering stable blue and violet hues.
• Drying Agent: Functions as an efficient siccative (drier) in paints, varnishes, and printing inks to accelerate the oxidation and polymerization of oils.
• Animal Nutrition: Serves as a source of essential cobalt in mineral feed supplements for ruminants.
• Chemical Synthesis: Employed as a reagent and intermediate in various organic synthesis processes and laboratory research.

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 tightly sealed to prevent absorption of atmospheric moisture. Keep away from incompatible materials such as strong oxidizing agents.
