Sodium Pyrosulfate (CAS 13870-29-6) Product Overview

Key Specifications

Chemical Properties

Na₂S₂O₇ demonstrates unique thermal stability (decomposes at 460°C) and redox properties, making it superior to alternative sulfates in high-temperature industrial processes.

Industrial Applications & Functional Advantages

Water Treatment Solutions

As a powerful oxidizing agent, Sodium Pyrosulfate achieves 99.9% microbial control in cooling towers at 50ppm concentration, outperforming traditional chlorine-based disinfectants in high-pH environments.

Metal Surface Preparation

In automotive manufacturing, 5-7% Na₂S₂O₇ solutions remove oxide layers 40% faster than sulfuric acid alternatives, while minimizing hydrogen embrittlement risks.

Chemical Synthesis

Laboratory tests confirm 22% higher reaction yields when using reagent-grade Sodium Pyrosulfate as a dehydrating agent in esterification processes compared to sodium bisulfate.

Operational Guidelines & Safety Protocols

Storage Requirements

• Maintain relative humidity below 45%
• Store separately from alkaline substances
• Maximum stack height: 2.5m

Emergency Procedures

For accidental exposure: Immediately flush eyes/skin with 0.9% sodium bicarbonate solution for 15 minutes. Never use water alone due to exothermic reaction risks.
