301 can be used for the market segments: polymer production and acrylics production with their different applications/functions. For more information please check our website and/or contact us.

Half-life data

The reactivity of an organic peroxide is usually given by its half-life (t1/2) at various temperatures. For 301 in chlorobenzene half-life at other temperatures can be calculated by using the equations and constants mentioned below:

0.1 hr	170°C (338°F)
1 hr	146°C (295°F)
10 hr	125°C (257°F)
Formula 1	kd = A·e-Ea/RT
Formula 2	t½ = (ln2)/kd
Ea	150.23 kJ/mole
A	1.02E+15 s-1
R	8.3142 J/mole·K
T	(273.15+°C) K

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	110°C (230°F)
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).

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, Thousands Chemicals recommends a maximum storage temperature (Ts max. ) for each organic peroxide product.

Ts max.	40°C (104°F)
Ts min.	10°C (50°F)
Note	When stored under these recommended storage conditions, 301 will remain within the Thousands Chemicals specifications for a period of at least 12 months after delivery.

Packaging and transport

The standard packaging is a 30-liter for 25 kg peroxide formulation. Both packaging and transport meet the international regulations. For the availability of other packed quantities consult your Thousands Chemicals representative. 301 is classified as Organic peroxide type D; liquid, Division 5.2; UN 3105.

Safety and handling

Keep away from open fire, sparks and other sources of heat or ignition. Avoid contact with reducing agents (e.g. amines), acids, alkalis and heavy metal compounds (e.g. accelerators, driers and metal soaps). PLEASE Store 301 ABOVE 10°C! Please refer to the Safety Data Sheet (SDS) for further information on the safe storage, use and handling of 301. This information should be thoroughly reviewed prior to acceptance of this product.
