[Chemical Knowledge]：Specification for storage and transportation of hydrogenated xylene

In the field of chemical production raw materials, the safe storage and transportation specifications
of hydrogenated xylene
1. Introduction

Hydrogenated xylene is a common chemical production raw material, widely used in petroleum, chemical, pharmaceutical and other fields. However, due to its flammable, toxic and harmful characteristics, hydrogenated xylene has greater safety risks during storage and transportation. Therefore, in order to ensure the safe storage and transportation of hydrogenated xylene, strict norms must be formulated and effective measures must be taken to ensure the safety of people's lives and property.

2. the physical and chemical properties of hydrogenated xylene

hydrogenated xylene is a colorless transparent liquid with aromatic odor. Its main component is C8H10, molecular weight is 106.17, density is 0.86-0.88g/cm3, boiling point is 137-140 ℃, flash point is 25 ℃, spontaneous ignition point is 536 ℃, explosion limit is 1.1-7.0%. Hydrogenated xylene is insoluble in water, but miscible with alcohols, ethers, acetone and other organic solvents.

3.
of Hydrogenated Xylene
Hydrogenated Xylene is a flammable and explosive hazardous material, which may cause combustion and explosion when exposed to open flame, high heat or oxidant. The vapor of hydrogenated xylene is heavier than air and can diffuse to a considerable distance at a lower point, and it will catch fire and backburn in case of fire source. In case of high heat, the internal pressure of the container increases, and there is a risk of cracking and explosion.

4. of hydrogenated xylene storage specification

1. The storage place should be cool, ventilated, away from fire, heat source, prevent direct sunlight. The warehouse temperature should not exceed 30 ℃.
2. Storage containers must be sealed to prevent leakage. It should be stored separately from oxidants and edible chemicals, and mixed storage should not be allowed. Explosion-proof lighting and ventilation facilities shall be adopted. It is forbidden to use mechanical equipment and tools that are easy to produce sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.

5.

1. Before transportation, check whether the packaging container is complete and sealed. During transportation, ensure that the container does not leak, collapse, fall or damage. It is strictly prohibited to mix with acids, oxidants, food and food additives.
2. The transport vehicles shall be equipped with corresponding varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment. The exhaust pipe of the vehicle carrying the goods must be equipped with fire retardant device, and it is forbidden to use mechanical equipment and tools that are easy to produce sparks for loading and unloading. It is strictly prohibited to mix and transport with oxidant, etc. In summer, it should be transported sooner or later to prevent sunlight exposure. Stay away from kindling and heat sources during stopover. Road transportation shall be carried out according to the prescribed route, and do not stop in residential areas and densely populated areas. It is forbidden to slip away during railway transportation.

6. Hydrogenated Xylene Safety Operation Specification

1. Closed operation, strengthen ventilation. Operators must be specially trained and strictly abide by the operating procedures. It is recommended that the operator wear self-priming filtering gas mask (half mask), chemical safety goggles, anti-poison penetration overalls and rubber oil-resistant gloves. Keep away from fire and heat sources. Smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent vapor leakage into the workplace air. Avoid contact with oxidizing agents. When filling, the flow rate should be controlled, and there is a grounding device to prevent static accumulation. Handle lightly to prevent damage to packaging and containers. Equipped with corresponding types and quantities of fire fighting equipment and leakage emergency treatment equipment. Empty containers may leave harmful substances.
2. Store in a cool, ventilated warehouse. Keep away from fire and heat source. The temperature of the warehouse should not exceed 37 ℃. Keep container sealed. Should be stored separately from the oxidant, do not mix storage. Explosion-proof lighting and ventilation facilities shall be adopted. It is forbidden to use mechanical equipment and tools that are easy to produce sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.

7. conclusion

hydrogenation of xylene as a common chemical production raw material, there is a greater safety risk in the process of storage and transportation. In order to ensure its safety, it is necessary to formulate strict norms and take effective measures to prevent and control. Only in this way can we ensure the safety of people's lives and property and promote the healthy development of the chemical industry.
