| titleOfInvention | A kind of method preparing 1,1,1,4,4,4-hexafluoro-2-butylene |
| abstract | The invention discloses one and prepare 1,1, Isosorbide-5-Nitrae, the method for 4,4-hexafluoros-2-butylene, is CH by formula m X n Y 4-n-m (m is 0 or 1, n is 1,2 or 3, and X, Y are selected from F, Cl or Br。) and HCFO-1233zd(CHCl=CHCF 3 ) heat of mixing additive reaction。Obtained intermediate hydrogen fluorine chlorine (bromine) butane or free HCl through vapor phase cracking, or utilize fluorination catalyst carry out HF fluoride or utilize zinc powder to carry out dechlorination。The product that reaction generates through filtrations, alkali cleaning, washing, dry, compress, after rectification and purification namely respectively highly purified 1,1,1,4,4,4-hexafluoro-2-butylene product。It is simple that the present invention has technique, and raw material is easy to get, it is easy to industrialization, environmental protection advantage。 |
