LA PRESENTE INVENCION PROPORCIONA UN NUEVO METODO DE PRODUCCION DE FLUOROMETIL 1,1,1,3,3,3 ES UN METODO DE PRODUCCION CONSISTENTE EN PONER EN CONTACTO EL POLIETER REPRESENTADO POR LA SIGUIENTE FORMULA GENERAL (1), CON UN MEDIO QUE COMPRENDE FLUORURO DE HIDROGENO Y UN ACELERADOR, R SUP,1}O(CH SUB,2}O) SUB,N}R SUP,2} (1) DONDE R SUP,1} Y R SUP,2} SON INDEPENDIENTEMENTE HIDROGENO, GRUPOS ALQUILO O HALOALQUILO C SUB,1} BROMO, N ES UN ENTERO ENTRE 1 Y 10 Y R SUP,1} Y R SUP,2} NO SON AMBOS HIDROGENO SIMULTANEAMENTE. The present invention provides a novel method of producing fluoromethyl 1,1,1,3,3,3-hexafluoroisopropyl ether. It is a method of producing fluoromethyl 1,1,1,3,3,3-hexafluoroisopropyl ether by bringing a polyether represented by the following general formula (1) into contact with a medium comprising hydrogen fluoride and an accelerant, R O(CH2O)nR where R and R are independently hydrogen, C1-C10 alkyl or haloalkyl groups, where halogen is fluorine, chlorine or bromine, n is an integer of from 1 to 10, and both of R and R are not hydrogen at the same time.
