Methylnonafluor- n -butyl ether is one of the hydrofluoroethers . The compound is slightly toxic, hardly soluble in water, non-flammable, non-volatile and non-ozone-damaging ( ozone depletion potential 0).

use

Since the ban on chlorofluorocarbons , it has been used as a cleaning agent in electronics and optics. It has a kauri-butanol value (solvent power) of 10.

Coolant

Methylnonafluor- n -butyl ether is in admixture with Methylnonafluor- iso -butyl ether (2- (difluoromethoxymethyl) -1,1,1,2,3,3,3-heptafluoropropane, CAS Number 163702-08-7) as a refrigerant ( R -7100 ) are used. The mixture has a vapor pressure of 64,600 Pa (at 25 ° C), is sparingly soluble in water at about 0.06 g · l ⁻¹ (25 ° C) and has a global warming potential of 587 (100 years).
