Simple SummaryContent extracted from patent full text and abstract with AI.

This invention provides a method to safely and efficiently release chlorine gas from polychloride-based storage media using protic release agents (like water or acids), allowing controlled delivery of chlorine gas for use in chemical reactions or disinfection processes. The chlorine-containing storage medium is based on organic ionic compounds that are stable at low pressure and can release chlorine on demand without the need for pressurized gas cylinders.

Use CasesContent extracted from patent full text and abstract with AI.

  • Water and wastewater disinfection in municipal or industrial settings, replacing traditional chlorine gas cylinders.
  • On-demand generation of chlorine gas for laboratory-scale or industrial-scale organic synthesis reactions (e.g., chlorination reactions).
  • Portable or small-scale chlorine delivery systems for remote locations or emergency water purification.
  • Chlorination systems for swimming pools, cooling towers, or other facilities needing microbial control with improved safety.
  • Decentralized water treatment plants or field hospitals where handling chlorine gas cylinders is impractical.

BenefitsContent extracted from patent full text and abstract with AI.

  • Improved safety by avoiding use and transport of high-pressure chlorine gas cylinders.
  • Enables precise control over the amount and timing of chlorine gas release, reducing risks of overdose or accidental exposure.
  • Simplifies the logistics and handling of chlorine gas, reducing equipment costs and maintenance.
  • Reusability of the storage medium after chlorine is spent, reducing waste and supply chain burden.
  • Operation under atmospheric pressure and ambient temperature, making the process less hazardous and easier to integrate into existing systems.
  • Potential for miniaturization and decentralized chlorine generation.
  • Reduction in regulatory and security requirements compared to pressurized gas handling.
