Fluoroether E-1Fluoroether E-1. This synthetic fluorochemical is used in the GenX process, and may arise from the degradation of GenX chemicals including FRD-903.ProductionThe main production of Fluoroether E-1 is within the GenX process where FRD-903 is used to generate ammonium 2,3,3,3-tetrafluoro-2-propanoate, and Fluoroether E-1.PropertiesFluoroether E-1 is a colorless liquid that is practically insoluble in water. It is volatile and has a low boiling point.
