The Proper Storge Of Organic Peroxide

We can minimize the probability of a peroxide decomposition by limiting the heat exposure of the product and preventing contamination. Temperature control is the most critical control measure in preserving quality and preventing a runaway reaction.

Although a number of organic peroxides can be safely stored at ambient temperature, most require some form of temperature control. The maximum temperature allowed by the regulatory agencies is the control temperature Tc . This temperature together with the emergency temperature (Tem, see section Temperature control and monitoring on this page) are derived from the SADT in next table.

However, for a longer shelf life, lower storage temperatures than the control temperature are generally recommended. At this recommended storage temperature (Ts ), as indicated on the product label, the product will be stable and quality loss will be minimal.

 As each organic peroxide has its own specific storage temperature, consult the product catalog or individual TDS . Temperature monitoring and control The temperature must be maintained at or below the recommended storage temperature; consult the product catalog or TDS. Organic peroxides should be protected from direct sunlight and all other sources of heat. Particular attention should be given to: • windows (not recommended or should be blinded), • heating systems (e.g. radiators, warmwater pipes, etc).

Cooled storage rooms should be provided with at least two independent temperature alarms. An alarm is recommended when the storage temperature is exceeded by 5°C. If this is the case the store should be inspected. The temperature alarm should incorporate some delay device to allow for intermittent short temperature increase which result from inspection, loading and unloading, etc. Any possibility of alarm de-activation should be countered with an automatic alarm re-activation. 

Non-cooled storage rooms should be provided with an alarm set at the emergency temperature but not higher than 45°C. It is imperative that a signal from the mentioned alarm systems should not escape notice at any time including nights, weekends, etc. and that appropriately trained personnel are alerted. There should be dual power supply for the alarm system.
