7-Chloro-4-hydroxyquinoline is one of the organic compounds. When storing and transporting, many matters need to be carefully paid attention to.
When storing, the first choice of environment. It should be placed in a cool, dry and well-ventilated place. Because 7-chloro-4-hydroxyquinoline is afraid of moisture and heat, if it is in a high temperature and humid place, its chemical properties or changes, resulting in damage to quality. If the humidity is too high, it may cause deliquescence; if the temperature is too high, it may cause decomposition reaction.
The second time is the container of choice. It must be stored in a container with good sealing performance to prevent excessive contact with air. Oxygen, water vapor, etc. in the air can chemically react with 7-chloro-4-hydroxyquinoline. Store in glass or plastic bottles, and ensure that the cap is tightly closed. And it should be kept away from fire and heat sources, because it may be flammable or heat sensitive.
During transportation, the packaging must be stable. When wrapped in appropriate protective materials to prevent package damage caused by collision and vibration during transportation. If the package is damaged, 7-chloro-4-hydroxyquinoline leaks out, which may damage itself and endanger the transportation personnel and the surrounding environment.
Furthermore, there are requirements for transportation vehicles. Clean, dry, and free of other chemical pollution should be selected. Mixed transportation of different chemicals may cause dangerous chemical reactions. And the transportation process should be controlled by temperature and humidity, and the environment should be suitable according to its physical and chemical properties.
The escort personnel also need to be professional. Familiar with the characteristics of 7-chloro-4-hydroxyquinoline, in case of emergencies, can take correct countermeasures. In this way, 7-chloro-4-hydroxyquinoline is safe in storage and transportation, and the quality is the same as before.
