Abstract

The present invention discloses an industrial preparation method of perfluorotributylamine, and is cahracterized by that it uses tributylamine (C4H9)3N and anhydrous hydrogen fluoride HF as raw material, utilizes electrolysis to electrolyze hydrogen fluoride, and produce fluorine free radical on the cathode and flurinate tributylamine so as to obtain perfluorotributylamine (C4F9)3N. Said invention provides its chemical reaction formula and its preparation method formed from 6 steps of electrolysis of HF and dehydration; electrolyzing and fluorinating tributylamine; extracting perfluorotributylamine crude oil; retaining next period reaction; cleaning and precise distillation. Its used electrolytic cell includes cell body, condenser pipe, anode, cell cover.
