[Chemical Knowledge]：Specification for storage and transport of diisobutylene

Safety of Diisobutylene Storage and Transportation Specification

1. Introduction

Diisobutylene is an important chemical raw material, widely used in the manufacturing process of plastics, rubber, fibers and other polymer materials. However, due to its flammable, explosive, and toxic properties, diisobutylene has greater safety risks during storage and transportation. In order to ensure the safety of personnel and the smooth operation of production, it is very important to formulate a set of strict storage and transportation specifications for diisobutylene.

2. the physical and chemical properties of diisobutylene

diisobutylene is a colorless and transparent liquid with a pungent odor. Its density is larger than air, insoluble in water, soluble in organic solvents. Diisobutylene is flammable and may cause combustion and explosion when exposed to open flame, high heat or oxidant. Its vapor is heavier than air and can spread to a considerable distance at a lower point, and it will catch fire and backburn in case of a fire source. In case of high heat, the internal pressure of the container increases, and there is a risk of cracking and explosion.

3. storage specification

1. Storage facilities should be built in a well-ventilated place away from fire and heat sources, and the ground should be leakproof.
2. The storage container shall comply with the relevant national standards, and shall be inspected and maintained regularly to ensure that the container is intact.
3. The storage area shall be provided with obvious safety signs and warning signs, and smoking and open fire shall be prohibited.
4. The temperature and pressure should be strictly controlled during storage to avoid the decomposition and polymerization of diisobutylene.
5. The storage area shall be equipped with corresponding fire fighting equipment and leakage emergency treatment equipment.

4. transport specifications

1. transport vehicles should comply with the relevant national standards, with the corresponding explosion-proof, fire prevention, leakage prevention and other safety measures.
2. Keep running smoothly during transportation to avoid severe vibration and collision.
3. The temperature and pressure should be strictly controlled during transportation to avoid the decomposition and polymerization of diisobutylene.
4. During transportation, corresponding fire-fighting equipment and leakage emergency treatment equipment shall be provided.
5. Transport personnel should be professionally trained to understand the nature of diisobutylene and safe operating procedures.

5. leakage emergency treatment

1. If leakage is found, the operation should be stopped immediately, and the leakage source should be closed to prevent the leakage from entering the restricted space such as sewer and flood discharge ditch.
2. 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.
3. Large amount of leakage: construct embankment or dig pit for containment. Cover with foam to reduce steam disasters. Spray water cooling and dilution of steam, protection of site personnel, dilution of spills into non-combustible materials. 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. Hazardous characteristics: its vapor and air can form an explosive mixture. Burning and explosion caused by open fire and high heat energy. Can react strongly with oxidants. Explosive decomposition on contact with acid and alkali. In case of high heat, polymerization reaction can occur, releasing a large amount of heat and causing container rupture and explosion accident. Its vapor is heavier than air and can spread to a considerable distance at a lower level, causing backburning in case of an open flame.
2. Harmful combustion products: carbon monoxide, carbon dioxide.
3. Fire extinguishing method: Move the container from the fire to the open place as much as possible. Spray water to cool the fire container until the fire is extinguished. Containers in a fire scene that have discolored or produced sound from the safety pressure relief device must be evacuated immediately. Fire extinguishing agent: anti-soluble foam, dry powder, carbon dioxide, sand. Fire extinguishing with water is ineffective.

7. summary

diisobutylene as an important chemical raw material, its safe storage and transportation is very important. By understanding the physical and chemical properties of diisobutylene, strictly complying with the storage and transportation specifications, and equipped with corresponding emergency treatment equipment and fire fighting equipment, the safety risks in the storage and transportation process can be reduced, and the safety of personnel and the smooth progress of production can be guaranteed.
