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.

Laundry detergents and bleaching agents: It is commonly used as a source of active oxygen in laundry detergents and bleaching agents to remove stains and brighten fabrics.

Disinfectant: It can be used as a disinfectant to kill bacteria, viruses, and fungi.

Laboratory reagent: It is used as a laboratory reagent for the analysis of various compounds, including sugars, alcohols, and ketones.

Dental applications: It can be used as a teeth whitener in oral care products.

Environmental remediation: It can be used to remove pollutants from water and soil by breaking down organic compounds.

Pyrotechnics: It is used in pyrotechnic formulations to produce oxygen and as a bleaching agent for flame colorants.
