2,5-Dimethyl-2,5-di(tert-butylperoxy)hexane[3]
Overview
2,5-Dimethyl-2,5-di(tert-butylperoxy)hexane is an organic peroxide primarily used as a crosslinking agent in polymer chemistry. It is known for its ability to initiate radical polymerization, making it essential in the production of elastomers and plastics. This compound is particularly valued for its stability at room temperature and its controlled decomposition at elevated temperatures, which allows for precise polymerization processes. It is commonly referred to by its trade name Luperox 101.
Physical and Chemical Properties
The compound appears as a colorless to pale yellow liquid with a density of 0.86 g/cm³. It has a melting point of 8°C and decomposes at around 50°C, releasing free radicals that initiate polymerization. Its solubility in organic solvents like acetone and benzene makes it versatile for industrial applications. However, it is insoluble in water, which limits its use in aqueous systems. The molecular weight of 290.44 g/mol and its specific structure contribute to its high reactivity as a peroxide.
Main Applications
2,5-Dimethyl-2,5-di(tert-butylperoxy)hexane is widely used in the rubber industry for vulcanization processes, where it enhances the elasticity and durability of rubber products. It is also employed in the modification of plastics to improve their mechanical properties. In addition, this peroxide is used in the production of crosslinked polyethylene (PEX) and other thermosetting polymers. Its ability to control the polymerization process makes it indispensable in industries requiring high-performance materials.
Safety and Storage
Due to its flammable nature and potential to cause skin and eye irritation, proper handling of 2,5-Dimethyl-2,5-di(tert-butylperoxy)hexane is crucial. It should be stored in a cool, dry place away from heat sources and direct sunlight to prevent decomposition. Workers handling this chemical should wear appropriate personal protective equipment (PPE), including gloves and safety goggles. In case of spillage, absorbent materials should be used to contain the liquid, and the area should be ventilated to avoid inhalation of fumes.
B2B Procurement Guide
When procuring 2,5-Dimethyl-2,5-di(tert-butylperoxy)hexane, it is essential to verify the supplier's credentials and ensure they provide detailed material safety data sheets (MSDS). The reference price ranges between $50-$100 per kg, depending on purity and order quantity. Bulk purchases may offer cost savings, but proper storage facilities must be available to maintain the chemical's stability. Buyers should also consider the logistical requirements for transporting hazardous materials and ensure compliance with local regulations.
