n-Butyl acetate safe storage and transportation specifications
n-Butyl acetate is a common chemical production raw materials, widely used in coatings, printing inks, leather processing, spices manufacturing and other fields. However, n-butyl acetate has a certain toxicity and flammability, so strict compliance with relevant safety regulations is required during storage and transportation.

1. the nature and harm of n-butyl acetate

n-butyl acetate is a colorless transparent liquid with light fruit flavor. Relative density 0.872. Melting point -73 ℃. Boiling point 126.1 ℃. Refractive index 1.3993. Flash point (open cup) 21 ℃. Viscosity 0.74mPa · s. Self-ignition point 421.11 ℃. Vapor density 3.96. Vapor pressure 13.33kPa(27°C). Explosion limit 1.2~7.5%(volume). Can be miscible with a variety of organic solvents, insoluble in water. Flammable, vapor and air form explosive mixture, explosion limit 1.2~7.5 (volume). Toxic, LD50 about 4000 mg/kg. Stimulate the eyes, mucous membrane, can cause skin degreasing. Mistaken gastrointestinal symptoms, anesthesia, and liver and kidney damage.

2. n-butyl acetate safe storage specification

1. The storage place should be set in a well-ventilated, dry and cool place, avoiding direct sunlight and high temperature environment.
2. The storage container shall be made of materials with good sealing performance and corrosion resistance, such as stainless steel or glass steel container.
3. Fire-fighting equipment and leakage emergency treatment equipment shall be set in the storage place to ensure safety.
4. During the storage process, the sealing and integrity of the container should be checked regularly, and the leakage should be handled in time.
5. Storage personnel should be professionally trained to understand the nature of n-butyl acetate and safe operating procedures.

3. n-Butyl Acetate Safety Transportation Specification

1. Before transportation, the integrity and safety of the transportation vehicle should be checked to ensure that there will be no leakage accident during transportation.
2. During transportation, the vehicle speed should be kept stable, and sudden braking and severe vibration should be avoided to reduce the leakage risk of n-butyl acetate.
3. Transport vehicles should be equipped with obvious dangerous goods identification and warning signs to remind the surrounding vehicles and pedestrians to pay attention to safety.
4. Professional escorts shall be provided during transportation to ensure transportation safety.
5. After transportation to the destination, the goods should be unloaded in time and the quantity and integrity of the goods should be checked, and the abnormalities should be handled in time.

4. n-butyl acetate leakage emergency treatment

1. found n-butyl acetate leakage, should immediately start the emergency plan, organize professionals to deal.
2. A warning line shall be set up in the leakage area to prohibit irrelevant personnel from entering, and ventilation measures shall be taken to reduce the concentration of n-butyl acetate.
3. For a small amount of leakage, sand or other non-combustible materials can be used for adsorption or absorption, or a large amount of water can be washed and diluted into the waste water system.
4. For a large number of leaks, embankments or pits should be used to accommodate them, and foam should be used to cover them to reduce steam disasters. Transfer to tank truck or special collector with explosion-proof pump, recycle or transport to waste treatment site for disposal.

In short, n-butyl acetate, as a common chemical production raw material, needs to strictly abide by relevant safety regulations during storage and transportation to ensure the safety of personnel and the environment.
