A method for transferring TCPX (α, α, α′, α′-tetrachloro-p-xylene) into TFPX (α, α, α′, α′-tetrafluoro-p-xylene) is disclosed, which comprises the following steps: (a) providing a first reactant comprising TFPX; (b) mixing the first reactant with alkali metal fluorides, TCPX and phase transfer catalyst(s) to form a mixture, wherein the alkali metal fluorides is KF, CsF, NaF, LiF or the combination thereof, the phase transfer catalyst(s) is quaternary ammonium salt, quaternary phosphonium salt or the combination thereof; and (c) heating the mixture.
本发明公开了一种将TCPX(α,α,α′,α′-四氯-p-二甲苯)转化为TFPX(α,α,α′,α′-四氟-p-二甲苯)的方法,包括以下步骤:(a)提供含有TFPX的第一反应物;(b)将第一反应物与碱金属氟化物、TCPX和相转移催化剂混合形成混合物,其中碱金属氟化物为KF、CsF、NaF、LiF或其组合,相转移催化剂为季铵盐、季磷盐或其组合;(c)加热混合物。
