Technical Document
Brief Overview
Sodium perborate tetrahydrate is a white crystalline powder that is commonly used as a source of active oxygen in laundry detergents and bleaching agents. It can also be used as a disinfectant and a laboratory reagent.
Manufacturing Process
The manufacturing process of sodium perborate tetrahydrate typically involves the reaction between sodium borate and hydrogen peroxide in the presence of a catalyst such as magnesium sulfate. The reaction occurs in aqueous solution and produces sodium perborate tetrahydrate as a solid precipitate. The solid is then filtered, washed, and dried to obtain the final product. The overall chemical reaction can be represented as follows:
2 Na2B4O7 + 4 H2O2 → 4 NaBO3· 4 H2O + 2 H2O
The resulting sodium perborate tetrahydrate is a stable solid that can be stored and transported easily.
