2,5-Diméthyl-2,5-di(tert-butylperoxy)hex-3-yne

2,5-Dimethyl-2,5-di(tert-butylperoxy)hex-3-yne decomposes at a 10-hour half-life of about 141 °C, with a 1-hour half-life near 165 °C. The alkyne bridge between the two peroxide groups is what pushes decomposition this high, well above dialkyl peroxides such as DCP (117 °C).

Use the alkyne grade when the process runs above 180 °C, or when DCP's acetophenone by-product is unacceptable. Its higher decomposition temperature means the peroxide survives the mixing stage and reacts only in the final hot zone, and its decomposition products are more volatile, so they devolatilise more cleanly.

Store below 10 °C in a ventilated area away from heat, reducers and heavy-metal compounds. SADT is 60 °C, which places it in Class 5.2 (UN 3105) for transport. Cold-chain shipping is available; ask sales for the lane covering your region.

Yes. Every shipment includes a lot-specific certificate of analysis reporting purity and active oxygen. A technical data sheet and safety data sheet are available on request through our sales engineers.
