Product Usage

Organic fluorination agent Schwefeltetrafluorid(SF4) is a selective organic fluorination agent. Sulfur tetrafluoride will cause corrosion similar to hydrofluoric acid when it encounters moisture. It will be completely hydrolyzed into sulfur dioxide and hydrofluoric acid, and when it is partially hydrolyzed, it will generate toxic thionyl fluoride. SF4 is a very important fluorinated reagent in fluorine chemistry. It can convert hydroxyl compounds into monofluorinated compounds, aldehydes and ketones into difluorinated compounds, and can also convert carboxyl groups into trifluoromethyl groups. An important raw material for trifluoromethyl compounds.
