The safety of propylene carbonate storage and transportation specifications
1. Introduction
As a common chemical raw material, propylene carbonate is widely used in medicine, pesticides, plastics, batteries 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 production, transportation and use, it is very important to formulate a set of strict storage and transportation specifications for propylene carbonate.
2. the physical and chemical properties of propylene carbonate
propylene carbonate is a colorless transparent liquid with pungent odor. Molecular formula C4H6O3, molecular weight 102.09. Relative density 1.2066(20/4°C). Melting point -48.8 ℃. Boiling point 242 ℃. Refractive index nD(20 ° C.) 1.4203. Flash point (open cup) 118 ℃. Viscosity (20 ℃)1.66mPa · s. Insoluble in water, soluble in ethanol, ether and other organic solvents.
3.
of the toxicity of propylene carbonate
propylene carbonate is a low toxicity class. The oral LD50 of rats was 2900 mg/kg. Rabbit percutaneous LD50>5 ml/kg. But it is mildly irritating to the skin. Operators should wear protective equipment.
4. of propylene carbonate storage specification
1. The storage place should be selected in a dry, ventilated and cool place, avoiding direct sunlight and high temperature.
2. The storage container shall be made of corrosion resistant materials and shall be inspected and maintained regularly to ensure that the container is intact.
3. Obvious safety signs and warning signs shall be set up in the storage area, and fireworks and open fire operations are prohibited.
4. The amount of propylene carbonate should be strictly controlled during storage to avoid safety risks caused by excessive storage.
5. of propylene carbonate transport specifications
1. Transport vehicles should have the appropriate qualifications and certificates, transport personnel should be professionally trained, familiar with the nature of propylene carbonate and safe operation procedures.
2. During transportation, ensure the stable driving of the vehicle, avoid violent vibration and collision, and prevent damage and leakage of the packaging container.
3. Transport vehicles shall be equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment to deal with emergencies.
4. Road traffic safety regulations shall be strictly observed during transportation to ensure transportation safety.
6. of propylene carbonate safety operation specification
1. Operators should be professionally trained, familiar with the nature of propylene carbonate and safe operation procedures, wearing the appropriate protective equipment.
2. During operation, parameters such as temperature and pressure should be strictly controlled to avoid abnormal conditions such as over-temperature and over-pressure.
3. Keep the equipment clean during operation to prevent debris from entering the equipment and affecting the normal operation of the equipment.
4. The equipment shall be inspected and maintained after the operation to ensure the normal operation and safe use of the equipment.
7. conclusion
propylene carbonate as a common chemical raw material, its safe storage and transportation is very important. By formulating strict storage and transportation specifications and strengthening the training and management of operators, it can effectively ensure the safety of production, transportation and use, reduce safety risks, and improve the production and social benefits of enterprises.
