MEKP (Methyl Ethyl Ketone Peroxide), a commonly used organic peroxide, is extensively utilized as an initiator in polymerization reactions. Due to its reactive nature and potential hazards, proper packaging and storage are critical to ensure its safe transportation and storage. The following content elaborates on the packaging requirements and key temperature data for MEKP, according to the recommendations of the United Nations Committee of Experts on the Transport of Dangerous Goods:
1. Packaging Requirements for MEKP
1. Weight Limitations: It is recommended that each package not exceed 50 kilograms (110 pounds) to facilitate safe handling and transportation.
2. Container Material: Packaging containers should be made of new high-density polyethylene to ensure chemical stability and leak prevention.
3. Lid Design: The lids should include a Gore-Tex membrane (or similar material) which allows for ventilation while preventing liquid leaks. This design helps balance internal pressure and prevents over-pressurization due to temperature changes.
4. Cardboard Packaging: In composite packaging, the cardboard boxes must pass drop test experiments to ensure physical strength and protective capability during transit.
5. Stacking Recommendations: It is advised to stack no more than three layers of packages on a pallet to avoid deformation or damage to the packages at the bottom due to excessive weight.
2. Key Temperature Data for MEKP (Using Butanox M-50 as an Example)
1. Flash Point: The flash point of Butanox M-50 is around 70 degrees Celsius, which is higher than that of methanol or gasoline, indicating a lower likelihood of vapor-induced flash ignition under normal conditions.
2. SADT (Self-Accelerating Decomposition Temperature): Set at 60 degrees Celsius. SADT represents the highest permissible ambient temperature for reactive chemicals in specific packaging materials and sizes. Exceeding this temperature could lead to self-accelerating decomposition within 7 days.
3. Recommended Storage Temperature: Set at 25 degrees Celsius. Storing MEKP at this temperature significantly reduces the loss of quality and ensures safety in storage. During warmer conditions, such as in summer maritime transport, the use of refrigerated containers is typically recommended to control temperature.
4. Cardboard Packaging: In composite packaging, the cardboard boxes must pass drop test experiments to ensure physical strength and protective capability during transit.
