Half life data

The reactivity of an organic peroxide is usually given by its half life (t1/2) at various temperatures.

For TAHP in chlorobenzene:
　 t 　　　　 1 hr 　　　　 10 hr
　 at 　　　　 183℃ 　　　 165℃

Major decomposition products

　 Methane, Acetone, tert-Amyanol

Storage

　 Ts max.= 30℃

Packaging and transport

The standard packaging is a 25-liter HDPE can for 20 kg peroxide solution or a 220-liter HDPE drum for 190 kg peroxide solution.

TAHP is classified as Organic peroxide type F, liquid; Division 5.2; UN 3109; PG II.

Application

TAHP can be used as an initiator in bulk, aqueous solution and emulsion polymerization of styrene, acrylates and methacrylates.
The polymerization can be initiated by radicals generated by the thermal decomposition of TAHP above 110°C or through a redox mechanism at low temperatures.

The use as an oxidizing agent for hydrocarbons or other chemicals.
