SILVER PERCHLORATE - Nature
Open Data Verified Data
colorless to white crystals. Deliquescence. Relative density 2. 806 (25 ℃). Melting point 486 °c (decomposition). Soluble in water, soluble in aniline, pyridine, benzene, glycerol, nitrobenzene and other organic solvents. Strong oxidant. Extremely unstable, heating or friction can cause explosive decomposition. With acetic acid, aniline, glycerol, nitrobenzene, pyridine, toluene, ethanol and other organic contact can form the corresponding solvated crystals, such as the impact, will occur violent explosion. With combustible or metal powder can form explosive mixture, by impact, friction can cause fire explosion.

SILVER PERCHLORATE - Preparation Method
Open Data Verified Data
The sodium perchlorate solution and silver chloride are added into the double decomposition reactor according to a certain proportion, heated for double decomposition reaction to generate a mixture of silver perchlorate and sodium chloride, filtered to remove sodium chloride crystals, and the filtrate is evaporated and concentrated under reduced pressure, cooling crystallization and refining (re-dissolution),
After filtration, the filtrate was cooled and crystallized, centrifuged and dried to obtain silver perchlorate.
