FC-75
# FC-75

FC-75 is a fluorocarbon derivative of tetrahydrofuran with the chemical formula $C_8F_{16}O.$ It is practically insoluble in water.

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. However, other perfluorinated ether isomers will also result.

    $H(CH_2)_7COCl$ + HF → $H(CH_2)_7COF$ + $C_7H_{16}$ + $2C_8F_{16}O$ + HCl + $H_2$

A similar fluorocarbon-based coolant and solvent is perfluorohexane.
