Abstract

HEMIJSKI POSTUPAK, postupak za proizvodnju bis(fluor-metil)etra dovodjenjem u medjusobni kontakt formaldehida sa vodonik fluoridom u jednom reakciono/destilacionom sudu. Reakciono/destilacioni sud preporučljivo je da je u obliku jedne reakciono/destilacione kolone, kroz koju formaldehid i vodonik fluorid teku u suprotnim smerovima, što je takodje preporučljivo. Bis(fluormetil)etar se može prevesti u difluormetan, preporučljivo zagrevanjem bis(fluormetil)etra na povišenu temperaturu u prisustvu jednog katalizatora od metala, oksida metala, fluorida metala ili oksifluorida metala.
