How to safely store cyclohexane

Cyclohexane (Cyclohexane) is an organic solvent widely used in the chemical industry, which is commonly used in the preparation of nylon, rubber, detergent and other chemical products. Due to the flammable and volatile nature of cyclohexane, it is important to store it correctly and safely. This article will analyze in detail how to store cyclohexane safely, and introduce the relevant safety measures and storage conditions.

1. Storage environment selection

The storage environment of cyclohexane is very critical. Locations where cyclohexane is stored must be well ventilated to ensure that any gases volatilized from the cyclohexane are quickly vented and do not accumulate in the air and pose a risk of fire or explosion. The storage area should be away from fire sources, high temperature equipment and devices that are easy to cause combustion such as electric sparks. Cyclohexane has a low flash point of about -20°C, so it is very important to control the temperature of the storage area. It is recommended to store in a low temperature, dry place and avoid direct sunlight.

2. Storage container requirements

Choosing a suitable storage container is the second step to ensure safe storage of cyclohexane. Cyclohexane is corrosive and requires the use of corrosion-resistant materials for storage containers, usually recommend stainless steel or galvanized steel containers. The container shall be well sealed to prevent the volatilization of cyclohexane. Due to the flammable nature of cyclohexane vapors, storage containers shall be equipped with explosion-proof valves and pressure relief devices to avoid bursting due to excessive pressure in the container. The container should be marked with a warning sign of "flammable liquid" to remind the operator to handle it carefully.

3. Avoid electrostatic accumulation

Static electricity is a potential risk in cyclohexane storage because it can trigger sparks that can cause cyclohexane vapor to burn or explode. In order to avoid static accumulation, the storage container should be grounded, and special attention should be paid to the loading and unloading of cyclohexane. The operation should be carried out slowly to minimize the flow speed of the liquid to avoid static electricity. The use of anti-static devices and conductive equipment is also an effective measure to prevent accidents caused by static electricity.

4. Fire protection measures and emergency plan

Areas where cyclohexane is stored must be equipped with adequate fire fighting equipment, such as dry powder fire extinguishers or carbon dioxide fire extinguishers. These devices can respond quickly in the event of a fire and prevent the spread of fire. Staff also need to receive regular fire training, familiar with the fire emergency procedures. Clear emergency evacuation routes should be set up in the storage area and ensure that the routes are unobstructed. The condition and integrity of storage equipment should be checked regularly to prevent leakage due to aging or damage.

5. Cyclohexane safe storage period

Cyclohexane has a certain chemical stability, but long-term storage may also cause its quality to change. Therefore, it is suggested to follow the principle of "first in, first out" when storing cyclohexane, so as to ensure the priority use of cyclohexane stored earlier. The quality of cyclohexane should be tested regularly, including parameters such as purity and pH, to ensure that it does not affect production safety and product quality during use.

Conclusion

The safe storage of cyclohexane is very important for the safety of chemical production. Through the reasonable selection of storage environment, the use of appropriate storage containers, avoid static electricity accumulation, strengthen fire control measures and follow the storage period management, can effectively reduce the safety hazards and ensure the safe use of cyclohexane. It is hoped that the answer to the question of "how to safely store cyclohexane (Cyclohexane)" in this paper can provide practical guidance for chemical practitioners.
