It is one of the 3M Fluorinert fluids. It is used as an inert coolant fluid in electronics and other applications, and as a solvent. FC-75 can be synthesized by the same electrochemical fluorination process used to produce PFOA.[1] However, other perfluorinated ether isomers will also result.
- H(CH2)7COCl + HF → H(CH2)7COF + C7H16 + 2C8F16O + HCl + H2
A similar fluorocarbon-based coolant and solvent is perfluorohexane.
