Half life data

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

For EHPC in chlorobenzene:
　 t 　　 0.1 hr 　　　　　　 1 hr 　　　　　　 10 hr
　 at 　　 83℃ 　　　　　　 64℃ 　　　　　　 47℃

Storage

　 EHPC Ts max. = -15℃ and
　 Ts min. = -25℃ to prevent crystallization

Packaging and transport

The standard packaging is a 25-liter HDPE can for 20 kg peroxide solution. Both packaging and transport meet the international regulations.
EHPC is classified as Organic peroxide type D; liquid, temperature controlled; Division 5.2; UN 3115; PG II.
Rail (RID) and air (ICAO-TI/IATA-DGR) transport are forbidden.

Major decomposition products

　Carbon dioxide, 2-Ethylhexanol

Application

1.Polymerization of ethylene

EHPC is an efficient initiator for the ethylene polymerization under high pressure in both autoclave and tubular processes.

To obtain a wide spectrum of polymerization temperatures, combinations with other peroxides are applied in practice.

2.Polymerization of vinylchloride

EHPC is applied as an initiator for the suspension and mass polymerization of vinylchloride in the temperature range between 40°C and 65℃.
