[Chemical Knowledge]：Specification for storage and transport of dibutyl ester

The safety of storage and transportation specifications

1. Introduction

dibutyl ester is a common chemical production raw material, widely used in plastics, rubber, paint, ink and other fields. However, due to its flammable and toxic properties, dibutyl ester has certain safety risks during storage and transportation. In order to ensure personnel safety and environmental safety, it is very important to formulate scientific and reasonable storage and transportation specifications for dibutyl ester. The physicochemical properties of

2. dibutyl ester

dibutyl ester is a colorless transparent liquid with a light fruit flavor. Its melting point is -35 ℃, boiling point is 277 ℃, flash point is 121 ℃, relative density is 0.97, insoluble in water, soluble in ethanol, ether and other organic solvents. Dibutyl ester belongs to low toxicity, but it is irritating to skin and eyes. Prolonged exposure can cause neurasthenia syndrome.

3. dibutyl ester safety storage specification

1. The storage place should be selected in a well-ventilated, dry and cool place, avoiding direct sunlight and high temperature.
2. The storage container shall be a special container with good sealing performance to prevent leakage.
3. The storage area should be set up obvious safety warning signs, no fireworks.
4. The storage area shall be equipped with corresponding fire fighting equipment and leakage emergency treatment equipment.
5. Check and maintain the storage container regularly to ensure that it is intact.

4. dibutyl ester transport specification

1. transport vehicles should meet the relevant standards, with fire, explosion, anti-static and other safety performance.
2. Before transportation, check whether the goods are packaged in good condition to ensure that there is no leakage.
3. Keep stable during transportation to avoid violent vibration and collision.
4. Transportation vehicles shall be equipped with corresponding fire fighting equipment and leakage emergency treatment equipment.
5. It is strictly prohibited to mix with oxidants, acids, edible chemicals, etc.
6. During transportation, traffic rules should be observed, safe speed should be maintained, and long-distance transportation and night driving should be avoided.
7. After arriving at the destination, the consignee shall handle the handover procedures in time to ensure the safe delivery of the goods.

5. leakage emergency treatment

1. When dibutyl ester leakage is found, the operation should be stopped immediately, and the leakage source should be closed to prevent the leakage from spreading.
2. For a small amount of leakage, sand, dry lime or soda ash can be mixed and recycled into a special container.
3. For a large number of leaks, embankments or pits should be built and covered with foam to reduce steam disasters.
4. Transfer to a tanker or special collector with an explosion-proof pump, and recycle or transport to a waste treatment site for disposal.
5. A warning area shall be set at the leakage site to prevent irrelevant personnel from entering and cut off the fire source. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and fire protection clothing. Cut off leakage sources as much as possible to prevent entry into restricted spaces such as sewers and flood drainage ditches. Small amount of leakage: adsorption or absorption with sand or other non-combustible materials. Can also be washed with a lot of water, wash water diluted into the waste water system. A large number of leaks: build a dam or dig a pit to accommodate; cover with foam to reduce steam disasters. Transfer to tank truck or special collector with explosion-proof pump, recycle or transport to waste treatment site for disposal.

6. fire protection measures

1. fire extinguishing method: with mist water, foam, dry powder, carbon dioxide, sand fire. Keep containers cool in the fire with water.
2. Fire-fighting precautions and measures: Firefighters must wear gas masks and full-body fire-fighting clothing to put out the fire in the upwind direction. Move the container from the fire to the open as much as possible. Spray water to keep the fire container cool until the end of the fire. Containers in a fire scene that have discolored or produced sound from the safety pressure relief device must be evacuated immediately. Fire extinguishing with water is ineffective.

7. conclusion

as a common chemical production raw material, there are certain safety risks in the process of storage and transportation. In order to ensure personnel safety and environmental safety, scientific and reasonable storage and transportation specifications must be formulated, and relevant regulations and operating requirements must be strictly observed to ensure the safe use and production of dibutyl ester.
