How to Safely Store Of (2-ethylhexyl) phthalate

Di (2-ethylhexyl) phthalate (Di (2-ethylhexyl) phthalate, DEHP) is a common plasticizer widely used in plastic products. Due to its chemical properties, the safe storage of DEHP is essential to avoid environmental contamination, health hazards and operational safety. In this article, we will discuss in detail how to safely store Di (2-ethylhexyl) phthalate to ensure their safety during use and storage.

1. Understand DEHP's physical and chemical properties

Before discussing how to safely store Di (2-ethylhexyl) phthalate, it is necessary to understand its physical and chemical properties. DEHP is a colorless and odorless oily liquid, insoluble in water, but soluble in organic solvents, with a certain degree of volatility. It is relatively stable at room temperature, but may decompose and release harmful substances in high temperature environment. DEHP is considered to be a potential environmental pollutant and hazardous to human health, so its storage conditions must be strictly controlled.

2. Storage environment requirements

The first principle of safe storage of DEHP is to provide a suitable storage environment. Since Di (2-ethylhexyl) phthalate is susceptible to temperature, it is recommended to store it in a cool, dry, and well-ventilated place, away from direct sunlight and extreme temperature fluctuations. The ideal storage temperature should be maintained between 10°C and 30°C to prevent material degradation. Excessive temperature may cause DEHP to volatilize or decompose, releasing harmful gases, so special attention should be paid to the temperature control system of the warehouse.

3. Storage container selection

Choosing the right storage container is the key to the safe storage of DEHP. It is recommend to use chemically resistant sealed containers, such as stainless steel or high-density polyethylene (HDPE) materials, to prevent leakage or container corrosion. Ensure that the container is well sealed to prevent the volatilization of DEHP and the entry of external pollutants. The container shall be marked with clear chemical identification, indicating its chemical name, harmfulness, production date and other information to facilitate subsequent management and identification.

4. Safety measures and leakage treatment

Although Di (2-ethylhexyl) phthalate is stable at room temperature, strict safety measures need to be taken during handling and storage. Adequate ventilation should be provided in the workplace to avoid prolonged exposure to DEHP vapors. The storage area should be equipped with appropriate leakage emergency equipment, such as absorbent materials and leakage prevention trays. In the event of a leak, workers should wear protective gloves, goggles and masks to quickly clean the area of the leak to avoid its spread to sewers or natural bodies of water.

5. Regulatory Compliance and Environmental Protection

When storing DEHP, it is also important to comply with relevant laws, regulations and industry standards. Di (2-ethylhexyl) phthalate is an environmental persistent organic pollutant, and its management is subject to strict environmental regulations. Storage and users need to understand and comply with local environmental regulations, especially in terms of waste disposal, to ensure that there is no pollution to the environment. Any expired or unusable DEHP shall be disposed of properly in accordance with hazardous waste disposal procedures.

6. Regular inspection and maintenance

Facilities and equipment storing DEHP should be inspected and maintained on a regular basis. In particular, the integrity of the sealed container, the temperature and humidity of the storage environment and the effectiveness of the safety equipment. These regular checks can help identify potential problems early and prevent accidents. Storage records and bills of materials should be kept up to date to ensure the traceability of chemicals and the transparency of management.

Conclusion

Safe storage of di (2-ethylhexyl) phthalate (Di (2-ethylhexyl) phthalate) requires strict environmental controls, proper container selection, sound safety measures and compliance with relevant regulations. Through good management and storage practices, leakage, volatilization and potential health and environmental risks of DEHP can be effectively avoided. Ensuring safe operation not only protects the health of workers, but also helps to reduce the impact on the environment.
