Anhydrous ethanol in the field of chemical production of raw materials in the safety of storage and transportation specifications

1. Introduction

anhydrous ethanol as a common organic solvent, widely used in chemical, pharmaceutical, food and other fields. However, due to its flammable and volatile characteristics, anhydrous ethanol has certain safety risks during storage and transportation. In order to ensure production safety and reduce the incidence of accidents, it is very important to develop a set of scientific and reasonable ethanol storage and transportation specifications.

2. the physical and chemical properties of anhydrous ethanol

anhydrous ethanol is a colorless transparent liquid with a special fragrance. Its molecular formula is C2H6O and its relative molecular mass is 46.07. Anhydrous ethanol flammable, vapor and air can form an explosive mixture, fire, high heat caused by combustion and explosion. In addition, anhydrous ethanol is irritating and may cause irritation to the skin, eyes and respiratory tract when exposed.

3. ethanol safety storage specification

1. storage place should choose dry, ventilated, cool place, away from fire, heat source.
2. The storage container shall be a special container with good sealing performance to avoid volatilization and leakage of anhydrous ethanol.
3. The storage area shall be provided with obvious safety warning signs and equipped with corresponding fire fighting equipment.
4. Check the storage container regularly to ensure that it is intact and prevent leakage.

4. ethanol safety transport specification

1. transport vehicles should have the appropriate qualifications and certificates to ensure that the transport process in line with the relevant laws and regulations.
2. Check the condition of the vehicle before transportation to ensure that the vehicle is in good condition and prevent malfunctions during transportation.
3. During transportation, the vehicle shall run smoothly, avoid violent vibration, collision and friction, and prevent the leakage of anhydrous ethanol.
4. Transportation vehicles shall be equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment to deal with emergencies.

5. anhydrous ethanol leakage emergency treatment measures

1. In case of anhydrous ethanol leakage accident, the leakage source should be cut off immediately, and the residual liquid should be absorbed by mixing sand, dry lime or soda ash.
2. When there is a large amount of leakage, embankment or pit shall be built and covered with foam to reduce steam disaster.
3. Transfer to tanker or special collector with explosion-proof pump, recycle or transport to waste treatment site for disposal.

6. ethanol safety precautions

1. before use should be a detailed understanding of the nature of ethanol and safety procedures, wear protective equipment.
2. The use of the process should maintain good ventilation, to avoid high concentration of anhydrous ethanol vapor caused by poisoning or combustion explosion accident.
3. Smoking or open fire operation near anhydrous ethanol is strictly prohibited to prevent fire accidents.
4. After use, the container should be sealed and stored to prevent evaporation and leakage of anhydrous ethanol.

7. conclusion

ethanol as a common organic solvent, plays an important role in the field of chemical production raw materials. However, due to its flammable and volatile characteristics, there are certain safety risks during storage and transportation. Therefore, it is very important to develop a set of scientific and reasonable specifications for the storage and transportation of anhydrous ethanol. Through strict compliance with norms and strengthening safety management, the accident rate can be reduced and production safety can be guaranteed.
