A process for the purification of fluoromethyl hexafluoroisopropyl ether which comprises contacting a crude composition comprising fluoromethyl hexafluoroisopropyl ether and hexafluoroisopropyl alcohol with a modifier in the presence of which the vapor pressure of the ether and/or the alcohol is modified whereby the difference in vapor pressure of the ether and the alcohol increases relative to the difference in vapor pressure of the ether and alcohol in the absence of the modifier and separating the ether from the alcohol.

Process for the purification of fluoromethyl hexafluoroisopropyl ether

A process for the production of fluoromethylhexafluoroisopropylether which comprises contacting bis(fluoromethyl)ether with hexafluoroisopropyl alcohol in which the molar ratio of the ether to alcohol is in excess of 2:1. The reaction takes place in the presence of a molar ratio of acid to hexafluoroisopropyl alcohol of 2:1 to 10:1.

Process for the production of fluoromethyl hexafluoroisopropyl ether

A process for the decomposition and removal of one or more fluorine containing compounds from a first gaseous mixture comprising the one or more fluorine containing compounds and water vapour, which process comprises the stages of: (i) contacting the first gaseous mixture with a catalyst comprising an aluminium based material to produce a second gaseous mixture comprising hydrogen fluoride and carbon oxides; and (ii) removing the hydrogen fluoride from the second gaseous mixture to produce a third gaseous mixture, which is substantially free of hydrogen fluoride.
