treating these mixture with anhydrous aluminum chloride at 150 /sR 160 °C during /sR 48 hrs in order to convert the latter into the easy-separable perfluoro(2,5,5- trichloro-2-alkyloxolane)s. Small quantities of new perfluoro(5,5-dichloroalkanoyl chloride)s were also among the chlorination products. The spectroscopic data as well as the physical properties of these new fluorination products, and perfluoro(2
将5种2-烷基取代的氧烷(如2-乙基氧烷,2-正丙基氧烷,2-异丙基氧烷,2-正丁基氧烷和2-正戊基氧烷)进行电化学氟化,得到相应的全氟(2-烷基氧烷) s。从这些起始原料与异构全氟(2-烷基氧戊烷),全氟(2-烷基-5-甲基氧杂戊烷)和全氟(二烷基醚)一起以高收率获得全氟(2-烷基恶烷)。在/ sR于150 / sR 160°C下用无水氯化铝处理这些混合物后,通过回收未反应的前者,成功地纯化了含有少量异构全氟(2-烷基氧戊烷)异构体的全氟(2-烷基氧烷)。为了将后者转化为易分离的全氟(2,5,5-三氯-2-烷基氧戊烷),需要48小时。少量新的全氟化合物(5,5-二氯链烷酰氯也属于氯化产物。介绍了这些新型氟化产物,全氟(2,5,5-三氯-2-烷基氧戊烷)和全氟(5,5-二氯链烷酰氯)的光谱数据以及物理性质。
