Mô tả
Colorless or white crystals dissolve in water, the solution is acidic, insoluble in alcohol. With moisture or heat gradually decompose to release oxygen. Odorless. Gradual decomposition of the loss of available oxygen, moisture can promote the decomposition, and rapid decomposition at high temperatures, decompose at about 100 ℃. Dissolved in 25 parts of water dissolved in about 50 parts of water (40 ℃), insoluble in ethanol, acidic aqueous solution. There are strong oxidizing. With organic friction or impact can cause a fire. There are strong irritant.ỨNG DỤNG
Analytical reagent, oxidant, develop photos.
Polymerization initiator. The photographic processing (vulcanization sulfate
was removed).
