Hydrogen Peroxide Adduct: Bulk Density 0.8-1.2 g/cm³

Component Specifications

Definition

Hydrogen peroxide adduct refers to a chemical compound where hydrogen peroxide (H₂O₂) is chemically bound or complexed with another substance, typically sodium carbonate or urea, to form a stable solid. In industrial sodium percarbonate bleaching agents, this adduct serves as the primary source of active oxygen, which is released during dissolution in water to provide bleaching, disinfecting, and oxidizing properties. The adduct structure enhances stability, shelf life, and controlled release compared to liquid hydrogen peroxide.

Working Principle

The hydrogen peroxide adduct works by dissolving in water, where it dissociates to release hydrogen peroxide. The hydrogen peroxide then decomposes into water and reactive oxygen species (primarily hydroxyl radicals and perhydroxyl anions) through catalytic or thermal activation. These species oxidize organic chromophores (color-causing molecules) in substrates like textiles, pulp, or surfaces, breaking double bonds and converting them into colorless compounds, thereby achieving bleaching and disinfecting effects.

Materials

Typically composed of hydrogen peroxide (H₂O₂) complexed with sodium carbonate (Na₂CO₃) to form sodium percarbonate (2Na₂CO₃·3H₂O₂), or with urea to form carbamide peroxide. May include stabilizers like sodium silicate, magnesium sulfate, or phosphonates to prevent decomposition. Purity: ≥85% active oxygen content for industrial grade.

Frequently Asked Questions

What is the main advantage of using a hydrogen peroxide adduct over liquid hydrogen peroxide?

The adduct offers improved stability, easier handling as a solid, reduced transportation hazards, and controlled release of active oxygen, enhancing safety and efficiency in industrial applications.

How does temperature affect the performance of hydrogen peroxide adduct in bleaching?

Higher temperatures (typically 40-95°C) accelerate the decomposition of hydrogen peroxide, increasing bleaching efficiency but risking over-bleaching or fabric damage if not controlled; optimal ranges depend on the substrate and process.
