摘要：
A process for the purification of fluoromethyl hexafluoroisopropyl ether involving contacting a crude composition containing impure fluoromethyl hexafluoroisopropyl ether with an adsorbent having pores with a range of pore sizes whereby the difference between the smallest and largest pore size is at least 1 nm. The adsorbent suitably is a form of silica, alumina, or carbon.
