1-氯-2-碘四氟乙烷易与四氟乙烯进行热调聚反应,形成低分子量调聚物,Cl(CF_2CF_2)_nI(n=2～5),可以蒸馏分离.在低温下调聚物与普通格氏试剂反应得氯氟烷基卤化镁,再由它获得ω-氯代全氟烯烃-1Cl(CF_2CF_2)_nCF=CF_2(n=1,2,3)、ω-氯代全氟烷基醇Cl(CF_2CF_2)_nCR′R″OH(R′=CH_3,R″=H;R′=R″=CH_3;R′=R″=CF_3;n=2,3)及ω-氯代全氟烷基磺酰氯Cl(CF_2CF_2)_nSO_2Cl(n=2,3,4).通过ω-氯代全氟羧酸甲酯与甲基碘化镁的反应也得到ω-氯代全氟烷基醇Cl(CF_2CF_2).CF_2C(CH_3)_2OH(n=1,2).ω-氯代全氟烷基磺酸钾是稳定性很好的表面活性剂,可用作电镀镀铬中的铬雾抑制剂.
1-Chloro-2-iodotetrafluoroethane is easily copolymerized with tetrafluoroethylene to form low molecular weight telomer Cl (CF_2CF_2) _nI (n = 2 ~ 5), which can be separated by distillation. The product was reacted with normal Grignard reagent to obtain chlorofluoroalkyl magnesium halide, and then it was obtained ω-chlorinated perfluoroolefin -1Cl (CF_2CF_2) _nCF = CF_2 (n = 1,2,3), ω-chloro- R ’= R “= CH_3; R’ = R” = CF_3; n = 2, 3) and omega-chloro Perfluoroalkylsulfonyl chloride Cl (CF 2 CF 2) _ n SO 2 Cl (n = 2, 3, 4) The ω-chloro perfluoroalkyl group was also obtained by the reaction of ω-chloromethyl perfluorocarboxylate with methylmagnesium iodide Alcohol Cl (CF_2CF_2) .CF_2C (CH_3) _2OH (n = 1, 2) .ω-potassium perfluoroalkyl sulfonate is a very stable surfactant, which can be used as chrome mist suppression in electroplating chrome plating Agent.
