Description

Carbonoperoxoic Acid, Oo-(1,1-Dimethylethyl) o-Methyl Ester (9Ci) is a specialized organic peroxide compound, also known as tert-Butyl peroxyacetate. This chemical is valued as a highly effective radical initiator and oxidizing agent for controlled polymerization and synthesis processes. It is primarily needed by manufacturers in the polymer, resin, and specialty chemical industries for applications requiring precise and efficient free-radical generation.

Application

• Polymerization Initiator: Used as a free-radical initiator in the production of polymers like polyethylene (LDPE), polystyrene, and polyvinyl chloride (PVC).
• Cross-linking Agent: Facilitates the cross-linking of unsaturated polyester resins and elastomers to enhance material properties.
• Organic Synthesis Intermediate: Serves as a key reagent in the synthesis of pharmaceuticals, agrochemicals, and fine chemicals.
• Curing Agent for Resins: Promotes the curing and hardening of thermoset resins in composite materials and coatings.
• Modifier for Polymer Properties: Employed to control molecular weight and branching during polymer modification processes.
• Oxidizing Agent in Specialty Reactions: Utilized in selective oxidation reactions where a strong, controllable oxidant is required.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its nature as a strong oxidizer, it must be segregated from reducing agents, acids, bases, and combustible materials. Recommended storage temperature is between 2°C and 25°C. Keep container tightly sealed when not in use to prevent decomposition.
