2-Amino-6-chloro-3-nitropyridine, there are many things to pay attention to when storing and transporting. This is because the substance has specific chemical properties, which is also related to its stability and safety.
First words storage. Must choose a cool, dry and well-ventilated place. Cover it is quite sensitive to temperature and humidity, high temperature and humid environment, easy to cause its chemical changes, resulting in damage to quality. Storage should be kept away from fire and heat sources to prevent fire or other accidents. And it needs to be stored separately from oxidants, acids, alkalis and other substances. Due to its chemical activity, if mixed with various substances, it may cause violent chemical reactions and cause danger.
As for transportation, it should not be neglected. Before transportation, it is necessary to ensure that the packaging is intact, and the packaging materials used must be able to effectively protect it from vibration, collision and external environment. During transportation, the driving should be stable, avoid sudden braking and sharp turns, and prevent package damage. Transportation vehicles should also be equipped with corresponding fire equipment and leakage emergency treatment equipment. If there is a leak on the way, it can be dealt with in time. The escort personnel must be professionally trained, familiar with the characteristics of the substance and emergency treatment methods to ensure the safety of the whole transportation process. In short, the storage and transportation of 2-amino-6-chloro-3-nitropyridine should be treated with caution, and all norms should be strictly adhered to to to ensure safety.
