Thermal stability

Organic peroxides are thermally unstable substances, which may undergo self-accelerating decomposition. The lowest temperature at which self-accelerating decomposition of a substance in the original packaging may occur is the Self- Accelerating Decomposition Temperature (SADT). The SADT is determined on the basis of the Heat Accumulation Storage Test.

SADT	60°C
Method	The Heat Accumulation Storage Test is a recognized test method for the determination of the SADT of organic peroxides (see Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria – United Nations, New York and Geneva).

Half-life data

The reactivity of an organic peroxide is usually given by its half-life (t1/2) at various temperatures. For CH 22-E50 in chlorobenzene:

0.1 hr	134°C (273°F)
1 hr	113°C (235°F)
10 hr	94°C (201°F)
Formula 1	kd = A·e-Ea/RT
Formula 2	t½ = (ln2)/kd
Ea	142.40 kJ/mole
A	3.47E+15 s-1
R	8.3142 J/mole·K
T	(273.15+°C) K

Storage

Due to the relatively unstable nature of organic peroxides a loss of quality can be detected over a period of time. To minimize the loss of quality, Greenrox recommends a maximum storage temperature (Ts max. ) for each organic peroxide product.

Ts max.	25°C
Note	When stored under the recommended storage conditions, CH335-29C90 will remain within the specifications for a period of at least 6 months after delivery.

Packaging and transport

The standard packaging is a 20 kg jerrycan. Both packaging and transport meet the international regulations. For the availability of other packed quantities consult your Greenrox representative. CH335-29C90 is classified as Organic peroxide type C; liquid, Division 5. 2; UN 3103.

Safety and handling

Keep containers tightly closed. Store and handle CH335-29C90 in a dry well-ventilated place away from sources of heat or ignition and direct sunlight. Never weigh out in the storage room. Avoid contact with reducing agents (e. g. amines), acids, alkalines and heavy metal compounds (e. g. accelerators, driers and metal soaps). Please refer to the Safety Data Sheet (SDS) for further information on the safe storage, use and handling of CH335-29C90. This information should be thoroughly reviewed prior to acceptance of this product.
