Selenium fluoride (SeF4), (T-4)- Use and Manufacturing
Regarding the preparation of selenium fluoride, only under strictly controlled reaction conditions, selenium can be directly fluorinated with fluorine to generate selenium fluoride, otherwise selenium hexafluoride will be obtained. It can also be obtained by adding selenium dioxide and sulfur tetrafluoride in a ratio of 1:4 to a reactor, and heating the reaction at 100-200℃ for 24h at a pressure of 100kPa. Selenium fluoride is mainly used as a fluorinating agent, such as the fluorination of alcohols, carboxylic acids, and carbonyl compounds.
