从聚三氟氯乙烯热解产物中分得一烯烃,C_4Cl_2F_6.经高锰酸钾氧化得相应的羧酸(C_2Cl_2F_3-COOH).该丙酸经Curtius降解得CCl_2FCOOH,其钠盐在乙二醇中热解得三氟氯乙烯和一饱和烃.根据H~1核磁共振谱和红外光谱证明后者是CCl_2FCF_2H.从而确证羧酸的结构为CCl_2FCF_2COOH,烯烃为CCl_2FCF_2CF=CF_2. From the polychlorotrifluoroethane pyrolysis products were divided into an olefin, C_4Cl_2F_6. Potassium permanganate oxidation to the corresponding carboxylic acid (C_2Cl_2F_3-COOH). The propionic acid was Curtius degradation of CCl_2FCOOH, the sodium salt in ethylene glycol The chlorotrifluoroethylene and a saturated hydrocarbon were pyrolyzed, and the latter was proved to be CCl 2 FCF 2 H according to H -1 NMR and IR spectra, confirming the structure of the carboxylic acid as CCl 2 FCF 2 COOH and the olefin CCl 2 FCF 2 CF = CF 2.
