| titleOfInvention | Preparation method of perfluorohexanone |
| abstract | The invention discloses a preparation method of perfluorohexanone, which takes hexafluoropropylene as a raw material, in the presence of alkyl hexamethylenetetramine villiaumite, partial hexafluoropropylene is oxidized by oxygen to generate hexafluoropropylene oxide, hexafluoropropylene oxide generates perfluoropropionyl fluoride through acylation reaction under the action of aminopyridine resin solid base, and then the perfluoropropionyl fluoride and unreacted hexafluoropropylene are condensed under the catalysis of fluorinion to prepare perfluorohexanone, wherein the reactions are all carried out in a pipeline reactor. The invention has the advantages of low technical cost, high reaction selectivity and yield, high product purity, simple post-treatment and no pollution, and is a green synthesis process. Is suitable for the clean production technology of enterprise scale production. |
