The safe storage and transportation specification
of benzene acetonitrile
1. Introduction

Benzene acetonitrile is an important organic chemical raw material, widely used in medicine, pesticides, dyes and other fields. However, phenylacetonitrile has certain toxicity and flammability, so it is necessary to strictly comply with relevant regulations during storage and transportation to ensure safety. This article will detail the safe storage and transportation specifications of phenylacetonitrile.

2. the physical and chemical properties of phenylacetonitrile

phenylacetonitrile is a colorless or slightly yellow transparent liquid with almond odor. Relative density 0.9624, melting point -12.8 ℃, boiling point 205.7 ℃, refractive index 1.5281, flash point 86 ℃. Insoluble in water, soluble in ethanol, ether and other organic solvents. In case of open flame, high heat or contact with oxidant, there is a danger of combustion and explosion. Thermal decomposition releases toxic nitrogen oxide flue gas.

3. benzene acetonitrile safe storage specification

1. storage place should be cool, ventilated, dry, away from fire and heat sources. The storage temperature should not exceed 30°C.
2. The storage container shall be closed to prevent leakage. Storage containers shall be inspected regularly to ensure that they are in good condition.
3. The storage area shall be provided with obvious safety warning signs and equipped with corresponding fire fighting equipment.
4. Avoid contact with oxidants, acids, alkalis and other substances during storage.
5. During the storage process, safety inspection shall be carried out regularly to discover and deal with potential safety hazards in time.

4. benzene acetonitrile safety transport specification

1. transport vehicles should meet the relevant standards, with the corresponding transport qualifications and conditions.
2. Before transportation, check whether the packaging is intact and whether the label is clear to ensure that there will be no leakage and other accidents during transportation.
3. During transportation, the road traffic safety regulations shall be observed, the speed shall be kept stable, and operations such as sudden braking shall be avoided.
4. Avoid high temperature, open fire and other dangerous factors during transportation to prevent fire, explosion and other accidents.
5. During transportation, corresponding fire-fighting equipment and leakage emergency treatment equipment shall be equipped to deal with emergencies.

5. benzene acetonitrile leakage emergency treatment specification

1. In case of leakage accident, emergency plan should be started immediately, and personnel should be organized for evacuation and rescue.
2. The leakage source should be cut off quickly to prevent the leakage from spreading. The spill may be covered and collected with adsorbent materials such as sand and dry lime.
3. Leakage collected shall be handled by professional units to avoid environmental pollution.
4. Personnel dealing with leakage accidents should wear protective gloves, masks and other personal protective equipment to prevent poisoning and burns.

6. conclusion

phenylacetonitrile as an important organic chemical raw material, in the process of storage and transportation need to strictly abide by the relevant norms to ensure safety. By understanding the physical and chemical properties of phenylacetonitrile and safe storage and transportation specifications, we can effectively prevent and reduce the occurrence of accidents and ensure the safety of people's lives and property.
