实验步骤: To a 300-mL stainless steel autoclave were added butyl acetate (80 g), 1-decene (15.2 g), and Perbutyl PV (a peroxide radical polymerization initiator produced by NOF Corporation, 0.21 g). The air in the autoclave was substituted with nitrogen and then cooled to 5° C. Subsequently, 2,3,3,3-tetrafluoropropene (18.6 g) was added to the autoclave. The inside of the autoclave was heated to 60° C. with stirring, whereby the reaction was initiated. After the reaction was performed for 16 hours with keeping the temperature in the autoclave at 60° C., temperature and pressure in the autoclave were brought to the ambient temperature and pressure to terminate the polymerization. Thereby, 105.9 g of a butyl acetate solvent of a 2,3,3,3-tetrafluoropropene/1-decene copolymer (solid content concentration: 1.5 mass %) was produced. produced by NOF Corporation, 0.21 g) The inside of the autoclave was heated to 60° C. at 60° C. were brought to the ambient temperature and pressure to terminate the polymerization

实验步骤: 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).
