Hexafluoroisopropyl methyl ether (HFE-356mmz), a downstream derivative of hexafluoropropylene oxide, a colorless and odorless liquid, is an important fluorine-containing high-end fine chemical. The downstream application of hexafluoroisopropyl methyl ether is mainly focused on the production of inhalation anesthetic sevoflurane. In addition, HFE-356mmz has excellent thermal stability and electrical properties, and is commonly used as a cooling medium for electronic devices; it is also widely used in the field of high temperature thermal management, such as integrated circuit manufacturing, semiconductor production, optical equipment and so on.
