General Description

Methyl perfluoro(2-methyl-3-oxahexanoate) is a chemical compound that belongs to the subclass of organofluorines. It is a colorless, odorless liquid with the molecular formula C7H5F13O3. METHYL PERFLUORO(2-METHYL-3-OXAHEXANOATE) is commonly used as a surfactant, which is a substance that helps to lower the surface tension between two liquids or between a liquid and a solid. It is also utilized in the production of fluorinated polymers and as a lubricant in various industrial applications. Additionally, it is being researched for its potential use in medical imaging and as an enhancer for the delivery of pharmaceuticals across biological barriers. However, its use and production are regulated due to concerns about its environmental impact and potential health risks.

The recovery of fluorinated emulsifiers branched

Described herein is a process for recovering a branched, ether-containing fluorinated emulsifier from an anion exchange resin by (1) contacting the anion exchange resin with a recovery fluid to form an eluate, the recovery fluid comprising an ammonium salt, water, and a water-miscible solvent, wherein the fluorinated emulsifier is of the formula: [Rf-(0-R′f)n-0-CF(CF3)-C(0)0-]i M+1; and (2) separating the anion exchange resin from the eluate.
