colorless or white orthogonal crystals. The relative density was 1. 95. Soluble in water, soluble in methanol, ethanol-soluble, acetone, almost insoluble in ethyl acetate, ether. Decomposition by heating. It is a strong oxidant, and can form an explosive mixture when mixed with a reducing agent, an organic substance, a flammable substance, and the like.
electrolysis-double decomposition method: the industrial sodium chlorate is heated with water in the dissolution tank to dissolve it to obtain a sodium chlorate solution with a concentration of 600 ~ 650g/L, and barium hydroxide is added to remove chromate and sulfate impurities, after a sufficient period of settling, the clear solution was sent to an electrolytic cell for electrolysis to produce a sodium perchlorate solution with a concentration of 800g/L. After the removal of fluoride and heavy metal ions, the sodium perchlorate solution is added to the double decomposition reactor, and ammonium chloride is added to the double decomposition reaction according to the measurement to generate the mixed solution of ammonium perchlorate and sodium chloride, and the sodium chloride crystal is removed by centrifugal filtration, the filtrate is evaporated and concentrated under reduced pressure, and the crude crystal of ammonium perchlorate can be obtained by cooling and crystallizing, redissolving and refining, cooling and crystallizing, particle size classification, centrifugal separation and drying to obtain ammonium perchlorate finished product.
It is mainly used as a rocket propellant. It can also be used in the manufacture of pyrotechnic. It can be used as the mixing agent of ammonium perchlorate explosive, artificial anti-hail agent, oxidant and analytical reagent.
packed in an iron drum lined with plastic bags, with a net weight of 25kg per drum. There should be obvious signs of "strong oxidant" and "explosive" on the package. The package shall also indicate the name, address, product name, trademark, grade, net weight, batch number or date of production. Class I inorganic
