Perfluorotanyl acid esterification method, and its straight chain content analyzing method

摘要: This invention provides a perfluoroctanoic acid and perfluoroctanoyl halogen esterification method, including:1) in the existence of catalyst BF3 add non-butyl alcohol with mole ratio 1:150; 2) heat mixtures under temperature 95-105deg.C to react for 2-3 hours. It also method that tests linear isomer halogen, which includes: 1) hours; 3) isopropyl ether solvent; 4) methylbenzene or normal octane internal standard; 5) use gas chromatography test contents isomer.
