Ethyl 1,2 - dihydro - 2 - ethoxy - 1 - quinolinecarboxylate, when storing and transporting, pay attention to many matters.
Its chemical properties are active, and when storing, it is necessary to choose a cool, dry and well-ventilated place. If placed in a warm and humid place, it may deteriorate. Because of its reaction with water vapor and oxygen in the air, the composition will change and lose its original characteristics. And it needs to be kept away from fire and heat sources to prevent the risk of fire and explosion, because it has a certain flammability.
When transporting, the packaging must be strict. Contain it in a sturdy, corrosion-resistant container to prevent it from leaking. Loading and unloading should be handled with caution. Do not subject the container to violent collisions or vibrations, so as not to damage the material and cause it to flow out. During transportation, it is also necessary to control its environmental conditions and maintain suitable temperature and humidity. If it is transported for a long time, it is necessary to regularly check whether the packaging is in good condition and whether there are any signs of leakage.
Also pay attention to the fact that this substance may be harmful to the human body and the environment. Those who come into contact should wear suitable protective equipment, such as gloves, goggles, protective clothing, etc., to avoid touching the skin, eyes, or inhaling its volatile gas. If it is accidentally leaked during transportation, it should be disposed of in accordance with relevant procedures as soon as possible to prevent it from polluting the surrounding environment.
