(E)-1-chloro-3,3,3-trifluoroprop-1-ene

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: WO 2008/054781 describes a preparation of HFO-1234yf by reaction of 2,3-dichloro-1,1,1-trifluoropropane (HFC-243db) in the presence of HF over a catalyst, in particular 98/2 Cr/Co. The reaction products comprise HFO-1234yf and 2-chloro-3,3,3-trifluoro-1-propene (HCFO-1233xf), the latter product being predominant; the other products 1-chloro-3,3,3-trifluoro-1-propene (HCFO-1233zd) and also 1,1,1,2,2-pentafluoropropane (HFC-245cb) and 1,3,3,3-tetrafluoro-1-propene (HFO-1234ze) are also formed. A higher temperature favors the production of the 1233zd isomer. The starting material, 2,3-dichloro-1,1,1-trifluoropropane (HFC-243db), is indicated as being obtained by chlorination of trifluoro-1-propene (TFP).
