Continuous preparation method of hexafluoropropylene trimer

The continuous preparation method comprises the following steps: in a microchannel reactor, a liquid phase catalyst preheated by hexafluoropropylene and a preheating module is reacted at 70 - 140 °C to obtain a hexafluoropropylene trimer. The liquid phase catalyst is prepared from component A, component B, component C and component D. The component A is at least one selected from the group consisting of potassium fluoride, cesium fluoride, and potassium hydrofluoride. The component B is selected from at least one 18 - crown ether -6, β - cyclodextrin and polyethylene glycol. The component C is selected from at least one of a nitrile compound, a glycol ether compound and an amide compound. The component D is selected from at least one of-4 -methyl -2 - pentene,2 - methyl -2 - pentene,2 - ethyl -3 and 3 -dimethylethylene oxide. The continuous preparation method has the advantages of accurate temperature control, good selectivity, continuous feeding, reusability of the catalyst and the like.

Synthesis of highly branched perfluoroolefins that are super-congested via multi-substitution of trifluoromethyl groups: Trifluoromethylation of hexafluoropropene trimers with Ruppert-Prakash reagent

The reaction of hexafluoropropene trimers with Ruppert-Prakash (CF3SiMe3) reagent gave highly congested perfluoroolefins such as the mono-trifluoromethylation products F-2,4-dimethyl-3-isopropyl-2-pentene (P1) and E- and Z-forms of F-4,4-dimethyl-3-isopropyl-2-pentene (2E and 2Z), and the bis-trifluoromethylation product F-2,4,4-trimethyl-3-isopropyl-2-pentene (3). The E-form of 2 was also comprised of two rotamers. Various aprotic polar solvents were surveyed for this reaction, and it was found that the aprotic solvent DMI has a unique solvent effect to selectively give the mono-trifluoromethylated perfluoroolefin P1, a precursor for the persistent perfluoroalkyl radical F-3-isopropyl-2,4-dimethyl-3-pentyl, in very high yield.
