Abstract
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.
