Preparation method of perfluoroheptanoic acid

The invention relates to the technical field of fluorochemical preparation, particularly a preparation method of perfluoroheptanoic acid. The method comprises the following steps: oxidizing dodecafluoroheptanol to obtain dodecafluoroheptanoic acid, carrying out reaction on the dodecafluoroheptanoic acid and thionyl chloride to obtain dodecafluoroheptanoyl chloride, carrying out fluorination on the dodecafluoroheptanoyl chloride to obtain perfluoroheptanoyl chloride, and hydrolyzing to obtain the perfluoroheptanoic acid. The technical process of preparing perfluoroheptanoic acid from dodecafluoroheptanol has the advantages of low energy consumption, no pollution and high yield (up to 75% or above), is easy to operate, and has higher competitive edges than the existing perfluoroheptanoic acid production technique.

HALOGEN FLUOROSULFATE REACTIONS WITH FLUOROCARBONS

The scope of the reaction of simple fluorocarbon halides with chlorine fluorosulfate and mixtures of chlorine and bromine fluorosulfate to produce RfOSO2F compounds has been investigated.It is shown that in many cases even primary chlorine in -CF2Cl groups can be replaced by -OSO2F.Primary bromine or iodine in -CF2X are more readily replaced.The mechanism of this replacement reaction has been established by the isolation of the metastable iodine III intermediate RfI(OSO2F)2.Neither secondary chlorine nor bromine in -CFX- groups is affected.With the secondary iodide, i-C3F7I, the salt + - is formed.Furthermore, it has been found that ClOSO2F is capable of converting fluorocarbon acids or their derivatives into fluorocarbon halides.A combination of these two ClOSO2F reactions with the known conversion of RfCF2OSO2F to the corresponding fluorocarbon acid offers a novel, high yield chain shortening reaction for the otherwise unreactive fluorocarbon halides according to:
