전기화학 불소화법을 이용한 PFTPA(Perfluoro TriPropylAmine)의 제조 장치 및 방법이 개시된다. 일 실시예에 따른 제조 방법은, 소정의 간격으로 이격되어 교대로 배치되어 있는 복수의 캐소드 전극판과 복수의 애노드 전극판 사이의 공간인 채널을 통하여, TPA(TriPropylAmine)와 불화수소의 혼합 용액을 강제대류시키면서 PFTPA을 제조하기 위한 방법으로서, 생성물인 PFTAA의 수율과 상기 생성물에 포함되어 있는 불순물의 농도를 고려하여, 상기 채널을 통해 흐르는 상기 혼합 용액의 유량을 제어한다. 일례로, 상기 캐소드 전극판과 상기 애노드 전극판은 3~5mm 간격으로 이격되도록 배치되어 있는 경우에, 상기 혼합 용액의 유량은 4~10L/min이 되도록 제어한다. Disclosed are an apparatus and a method for producing perfluoro tripropylamine (PFTPA) by using electrochemical fluorination. The production method according to an embodiment is a method for producing PFTPA by forced convection of a mixed solution of tripropylamine (TPA) and hydrogen fluoride, through a channel, which is the space between a plurality of cathode electrode plates and a plurality of anode electrode plates that are spaced apart from each other at predetermined intervals and alternately arranged, in which, by considering the yield of PFTAA as a product and the concentration of impurities contained in the product, the flow rate of the mixed solution flowing through the channel is controlled. For example, when the cathode electrode plates and the anode electrode plates are provided to be spaced apart from each other at intervals of 3-5 mm, the flow rate of the mixed solution is controlled to be 4-10 L/min.
