Paragraph 0039; 0045-0049, (2017/09/21)
The invention discloses a preparation method of hexafluoroisobutene, comprising the steps of (1) reacting heptafluoroisobutene methyl ether, methanol and a halide in type I solvent, cooling after reacting, filtering, rectifying the filtrate to obtain methyl hexafluoroisobutyrate; (2) allowing the methyl hexafluoroisobutyrate of step (1) to react with a reducing agent in type II solvent, quenching with hydrochloric acid after reacting, filtering, rectifying the filtrate to obtain hexafluoroisobutanol; (3) allowing the hexafluoroisobutanol of step (2) to react with an alkali in a molar ratio of 1:(1-10) in type III solvent, collecting the reaction product, and rectifying to obtain finished hexafluoroisobutene. The preparation method has the advantages that the process is simple, the yield is high, the raw materials are low in price and easy to obtain and the preparation method is suitable for industrialization.

α-Fluoroalkyl carboxylic acid esters and process for preparing the same
-
, (2008/06/13)
An α-fluoroalkyl carboxylic acid ester of the general formula STR1 wherein A is R1 R2 COR3 -- or R4 CO--, wherein R1 and R2 are independently hydrogen, alkyl, alkoxyl or phenyl, with or without the formation of a common ring therebetween, R3 is hydrogen or alkyl, R4 and R are independently alkyl, and Rf is fluoroalkyl. The α-fluoroalkyl carboxylic acid ester is prepared by reacting a fluoroalkyl silyl ketene acetal of the formula STR2 wherein R' is alkyl and Rf and R are the same as defined above, with the corresponding acetal, ketone or acyl halide.
