10031-68-2 - Introduction
Ammonium pyrosulfate is an inorganic compound with the chemical formula (NH4)2S2O8. The following is an introduction to the nature, use, preparation and safety information of ammonium pyrosulfate:
Nature:
1. appearance: ammonium pyrosulfate is colorless crystal or white crystalline powder.
2. stability: relatively stable at room temperature, but heat decomposition, release oxygen, sulfur dioxide and ammonia gas. In addition, it is readily soluble in water.
Use:
1. Oxidant: ammonium pyrosulfate is a strong oxidant that can be used for oxidation reactions in organic synthesis reactions.
2. high explosive liquid: ammonium pyrosulfate dissolved in aliphatic hydrocarbon solvent, can be used as a component of high explosive liquid explosives.
3. catalyst: ammonium pyrosulfate can also be used as a catalyst for some organic catalytic reactions.
Preparation Method:
Ammonium pyrosulfate can be prepared by reacting concentrated sulfuric acid with concentrated ammonia cooled to low temperature. The reaction equation is as follows:
2NH3 2H2SO4 → (NH4)2S2O8
Safety Information:
1. ammonium pyrosulfate is a strong oxidant, may cause fire or explosion in contact with other combustible materials, need to pay attention to safe operation.
2. contact with eyes, skin or inhalation of its dust may cause irritation. Use should wear protective gloves, protective glasses and other protective equipment to ensure adequate ventilation.
3. during storage, keep away from combustibles, organic matter and reducing agent and avoid mixing with them.
4. not with sulfuric acid, sodium chloride, acid or direct contact with combustibles, so as not to cause dangerous reaction.
5. if accidental contact or misuse, should immediately rinse with plenty of water, and seek the help of a doctor.
Please note that when using or handling ammonium pyrosulfate, follow relevant safety regulations and operating guidelines to ensure safety.
