METHOD FOR PREPARING HEXAFLUOROBUT-1,3-DIENE Russian patent published in 2007 - IPC C07C21/20 C07C17/23 

Abstract RU 2301220 C1

FIELD: chemical technology.

SUBSTANCE: invention relates to a method for synthesis of hexafluorobut-1,3-diene. Process is carried out by the dehalogenation reaction of 1,2,3,4-tetrachlorohexafluorobutane with zinc in medium of high-boiling organic solvents chosen from the following order: diethylene glycol, polyethylene glycol, dimethyl ether, tetraethylene glycol, adipodinitrile, hexamethylphosphatriamide. Method provides simplifying process and absence of organic solvent and water in the final reaction product.

EFFECT: improved method of synthesis.
