Fire extinguishing mixtures, systems and methods are provided. The fire extinguishing mixtures can include one or more extinguishing compounds, such as, for example, one or more of fluorocarbons, fluoroethers, and fluorocarbons. The fire extinguishing mixtures can also include one or more of nitrogen, argon, helium and carbon dioxide. In an exemplary aspect the extinguishing mixture includes an extinguishing compound, a diluent gas and water.

Fire extinguishing mixtures, methods and systems

Highly fluorinated, saturated, and unsaturated fluoroethers are efficient, economical, non-ozone-depleting fire extinguishing agents used alone or in blends with other fire extinguishing agents in total flooding and portable systems. Methods for producing ethers, halogenated ether intermediates, and fluoroethers are disclosed. Novel fluoroether compositions are disclosed. Fluoroether extinguishing mixtures, methods, and systems are disclosed.

Methods for preparing ethers, ether compositions, fluoroether fire extinguishing systems, mixtures and methods

A method for suppressing a fire at a burning material comprising delivering to said burning material (a) an inert gas and (b) a gaseous compound selected from the group consisting of a hydrofluorocarbon, an iodofluorocarbon, and a mixture thereof, gases (a) and (b) being delivered in a combined concentration sufficient to extinguish the fire.

Compositions for the suppression of fire

Method for the suppression of fire

3-bromo-1,1,1-trifluoropropane is produced by reacting 3,3,3-trifluoropropene with hydrogen bromide at elevated temperature, e.g., 150.degree. C. to 800.degree. C., in the presence of an active carbon catalyst. The conversion, yield and selectivity are unexpectedly high.
