The safe storage and transportation specification
of diethyl carbonate
1. Introduction

Diethyl carbonate is an important chemical raw material, widely used in medicine, pesticides, plastics, dyes and other fields. However, due to its flammable, toxic and other characteristics, the safety requirements for storage and transportation are extremely high. In order to ensure the safety of diethyl carbonate in the production, use and storage process, it is very important to formulate a set of strict storage and transportation specifications.

2. the physical and chemical properties of diethyl carbonate

diethyl carbonate is a colorless transparent liquid with pungent odor. Molecular formula C5H10O3, molecular weight 118.13. Relative density 1.0036(20/4 ℃), melting point -43 ℃, boiling point 125.8 ℃, refractive index 1. 3697, flash point (open cup) 42 ℃, viscosity 0.664mPa · s. Insoluble in water, soluble in ethanol, ether and other organic solvents.

3. the risk of diethyl carbonate

diethyl carbonate belongs to the flash point flammable liquid, in case of open flame, high heat easily cause combustion. In addition, diethyl carbonate has a certain toxicity, long-term exposure or inhalation can lead to human poisoning symptoms, such as dizziness, headache, nausea, vomiting and so on.

4. diethyl carbonate safety storage specification

1. storage place should be selected in a well-ventilated, away from the fire, and set up obvious safety warning signs.
2. Storage containers shall comply with relevant standards and be regularly maintained and inspected to ensure that the containers are intact.
3. During storage, the temperature should be strictly controlled to avoid direct sunlight to prevent the decomposition of diethyl carbonate to produce harmful gases.
4. The storage site shall be equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment to ensure that timely measures can be taken in case of emergency.

5. diethyl carbonate safety transport specification

1. transport vehicles should meet the relevant standards, with fire, explosion, anti-static and other safety performance.
2. It should be stable during transportation to avoid severe vibration and collision to prevent leakage caused by package damage.
3. During transportation, keep away from fire and heat sources and avoid direct sunlight to ensure safe transportation.
4. Transportation personnel should be professionally trained to understand the nature of diethyl carbonate and safe operating procedures to ensure that they can respond correctly in emergency situations.

6. leakage emergency treatment

1. In case of diethyl carbonate leakage, immediately start the emergency plan and organize professionals to deal with it.
2. A warning line shall be set up in the leakage area, and irrelevant personnel shall not be allowed to enter to prevent accidents.
3. Use special absorbent materials to absorb and treat the leakage to avoid flowing into sewers or drains.
4. In case of large leakage, embankment measures shall be taken to prevent the leakage from spreading.

7. conclusion

diethyl carbonate as an important chemical raw material, its safe storage and transportation is very important. By formulating strict storage and transportation specifications, strengthening the training of management and operators, ensuring the safety of diethyl carbonate in the production, use and storage process, and reducing potential risks. At the same time, effective emergency measures should be taken to reduce the impact on the environment and human health.
