What is Cobalt acetate?
Cobalt acetate (CAS 71-48-7), also sold as cobaltous diacetate, is an organometallic cobalt salt used primarily as a catalyst and metal source.
Where is Cobalt acetate used?
- Polymer and plastics manufacturing: catalyst or co-catalyst
- PET polymerization and oxidation reactions, influencing color and molecular weight
- Textile and leather processing: dye fixation and surface uniformity in dyeing and finishing baths
- Coatings and printing inks: drier catalyst accelerating oxidative cure in alkyd-based systems
- Pharmaceutical and biotechnology: cobalt precursor in synthesis
- It also serves as a trace metal supplement in fermentation media.
Commercial specifications
- Bulk in fiber drums or intermediate bulk containers; smaller packaging for laboratory use
