colorless needle-like crystals. The water of crystallization was lost by heating to 260 °c to give an anhydrate. The anhydrous is a white powder or granules. The relative density was 2. 74. Melting point 505 °c. Soluble in methanol, acetone and liquid ammonia, insoluble in ether and nitric acid. For a more stable perchlorate, it decomposes and releases oxygen by heating to 450 °c. Strong oxidant, and combustible materials, organic matter, metal powder or reducing agent to form explosive mixture, ignition or explosion caused by friction or heat, mixed with alcohols can form high explosive substances. Hygroscopic, easily soluble in water. Explosive.
double decomposition method: the sodium perchlorate solution is fed into the reactor, and barium chloride is added for double decomposition reaction to generate barium perchlorate and sodium chloride, and the sodium chloride is removed by filtration. The filtrate is evaporated and concentrated, cooled to crystallize and refined, after filtration, the filtrate was cooled and crystallized, centrifuged and dried
After drying, barium perchlorate was obtained.
is used as a rocket fuel, a gas desiccant, a dehydrating agent, and the like. It is also used as a chemical reagent.
pack in glass bottles, each with a net weight of 0.5, and concentrate on the bedding in the wooden box; Or pack in sealed iron barrels lined with plastic bags, with a net weight of 40kg per barrel. Package shall be marked with "oxidant" and "explosive. It is a Class I inorganic oxidant. Risk code: GB 5.1 class 51022. UN N0.1448;IMDG CODE P. 5129, category 5.1. Collateral Hazard Class 6.1. Storage in a cool, ventilated, dry warehouse, packaging must be sealed. Stay away from heat sources and fire types. It shall not be stored and mixed with flammable and explosive articles, organic matter, oil and concentrated acid, edible chemicals, sulfur and other articles. During transport to prevent rain and exposure. Pay attention to moisture. When loading and unloading, it is necessary to take it lightly, and collision or friction is strictly prohibited. The "five pairs" management system of extremely toxic substances should be strictly implemented. When there is a fire, it can be suppressed by fog water and sand. Toxicity
Sex and protection: This product is highly toxic, and has strong irritation to respiratory tract, eyes and skin. Oral cause salivation, Vomit, abdominal spastic pain, slow pulse, elevated blood pressure, blood potassium decreased, gastrointestinal bleeding may occur, followed by progressive muscle paralysis and myocardial damage. Severe cases can die of heart rhythm disorders and respiratory muscle paralysis. If you accidentally splash into the skin or eyes, rinse with running water or saline. The patient visited hospital. If you accidentally eat, you should immediately drink a sufficient amount of warm water, emetic. Gastric lavage with 2% ~ 5% sodium sulfate solution, catharsis. The patient visited hospital. Production personnel should wear work clothes, protective masks or gas masks, latex gloves, and long rubber boots. Production equipment should be closed and the workshop should be well ventilated. Smoking, eating and drinking are prohibited at work. Take a shower after work.
