What should be paid attention to when storing and transporting Ethyl O-Toluene Sulfonate?
Ethyl O-Toluene-Sulfonate is an organic compound, and its storage and transportation need to be careful. If there is a slight mistake, it will cause disaster.
When storing, the first choice for the environment. Must find a cool, dry and well-ventilated place, away from fire and heat sources. Because of its flammability, it is very easy to burn in the event of open flames and hot topics. If the ambient temperature is too high, it may cause its volatilization to accelerate, and the concentration will accumulate, increasing the risk of explosion.
Furthermore, storage containers are also crucial. Containers with good sealing performance are required to prevent volatilization and leakage. When the material is resistant to corrosion, if the glass or specific plastic material container is not treated with corrosion resistance, it may be eroded, causing damage to the container and material leakage.
Ethyl O-Toluene-Sulfonate is quite sensitive to humidity, humid environment or chemical reactions such as hydrolysis, so the humidity at the storage place should be controlled within a reasonable range. The desiccant can be placed in the storage space to absorb moisture and prevent moisture.
When transporting, the packaging must be tight and stable. Follow relevant transportation regulations, use suitable packaging materials, and take good protection to prevent package damage caused by collision and vibration.
Transportation vehicles are also required to be clean without residual impurities, especially vehicles that have transported dangerous chemicals, which need to be thoroughly cleaned, otherwise the residual substances may react chemically with Ethyl O-Toluene-Sulfonate.
Transportation personnel should also be professionally trained and familiar with their characteristics and emergency treatment methods. During transportation, pay close attention to environmental factors such as temperature and humidity. If there is any abnormality, take measures quickly to ensure transportation safety and avoid harm to personnel and the environment.
