The safety of acetaldehyde storage and transportation specifications

1. Introduction

Acetaldehyde is an important chemical raw material, widely used in plastics, synthetic fibers, rubber, medicine, pesticides and other fields. However, acetaldehyde is toxic and flammable, and requires high safety for storage and transportation. In order to ensure the safety of acetaldehyde in the process of production, storage and transportation, it is necessary to formulate a set of strict specifications.

2. the physical and chemical properties of acetaldehyde

acetaldehyde is a colorless, pungent liquid with a molecular formula of C2H4O and a molecular weight of 44.05. Acetaldehyde has a boiling point of 20.8°C, a melting point of -123.5°C and a density of 0.785g/cm3. Acetaldehyde has strong reducibility and is easily oxidized to acetic acid. In addition, acetaldehyde is also flammable and toxic, which is harmful to the human body.

3. acetaldehyde storage specification

1. The storage place should choose a dry, ventilated, cool place, avoid direct sunlight and high temperature.
2. The storage container should be made of stainless steel or glass steel, avoid the use of iron containers, so as not to cause chemical reaction.
3. The storage container shall be well sealed to prevent acetaldehyde leakage and volatilization.
4. Fire-fighting facilities, such as fire extinguishers and fire hydrants, shall be provided at the storage site in case of emergency.
5. During the storage process, the integrity and tightness of the container should be checked regularly, and the leakage situation should be found and dealt with in time.

4. acetaldehyde transport specification

1. transport vehicles should meet the relevant standards, with fire, explosion, anti-static and other safety measures.
2. Keep running smoothly during transportation to avoid severe vibration and collision.
3. Keep away from open fire and high temperature places during transportation to avoid fire and explosion accidents.
4. In the process of transportation, the integrity and sealing of the goods should be checked regularly, and the leakage situation should be found and handled in time.

5. acetaldehyde safe operation specification

1. Operators should be professionally trained to understand the nature of acetaldehyde and safe operation procedures.
2. Before operation, check the integrity and tightness of the equipment to ensure the normal operation of the equipment.
3. Wear protective clothing and gloves during operation to avoid poisoning and allergy caused by contact with acetaldehyde.
4. Sparks and static electricity should be avoided during operation to avoid fire and explosion accidents.
5. After the operation, clean up the site and turn off the power and air source of the equipment to ensure safety.

6. of acetaldehyde emergency treatment measures

1. in case of acetaldehyde leakage accident, should immediately cut off the leakage source, with sand or other non-combustible adsorbent to absorb residual liquid, and put it in a safe place.
2. In the event of a fire accident, fire extinguishers, fire hydrants and other fire fighting equipment should be used immediately to extinguish the fire, and call the police for help in time.
3. In case of personnel poisoning accident, the poisoned person shall be moved to the ventilated place immediately, and necessary first aid and medical treatment shall be given.

7. conclusion

acetaldehyde as an important raw material for chemical production, its safety and reliability are of great significance to ensure the smooth progress of the production process. Therefore, in the process of storage, transportation and operation of acetaldehyde, we must strictly abide by the relevant norms and safety operation procedures, strengthen safety management and protective measures, and ensure the safety of personnel and the environment.
