FAQ
Oxidant stability and safety issues
Easy to decompose: Many oxidants are easy to decompose when heated, damp, exposed to light or in contact with other substances, generating heat, gas and even causing an explosion. For example, hydrogen peroxide, hypochlorous acid, etc. will spontaneously decompose under certain conditions, release oxygen, and increase the risk of explosion.
Explosive: some oxidants such as chlorates, nitrates and organic peroxides, etc., after friction, impact, vibration, etc., can easily cause explosion. Therefore, special care is required during storage, transportation and use.
Toxicity and corrosiveness: Some oxidants such as bromine pentafluoride are toxic and pose a threat to human health. At the same time, they may also be corrosive to materials such as metals and damage equipment or containers.
Oxidant reactivity issues
Strong oxidation: oxidant has strong oxidation, can react violently with a variety of substances, and even cause combustion or explosion. For example, they can react violently with inflammables, organics, reducing agents, etc., generating large amounts of heat and gas.
Violent reaction with acid: most oxidants will react violently with acid and even explode. Such as potassium chlorate, benzoyl peroxide, etc. in case of sulfuric acid that explosion. Therefore, these oxidizing agents must avoid contact with acids or alkalis during storage and use.
metathesis reaction: a metathesis reaction may occur between oxidants, resulting in high temperature, combustion and even explosion. For example, nitrite reacts violently when it encounters a stronger oxidant than it.
Oxidant storage and transportation issues
Strict storage requirements: The oxidant needs to be stored in a cool, dry, well-ventilated place, avoiding direct sunlight and high temperature environment. At the same time, different varieties of oxidants should be stored in stacks, and it is strictly prohibited to mix organic combustibles.
High transportation risk: During transportation, the oxidant needs to be especially careful to avoid vibration, friction and impact. At the same time, it is necessary to select appropriate packaging materials and transportation methods to ensure safe transportation.
