Abstract:
Disclosed is a process for the production of 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd) which includes reacting a propane feedstock comprising tetrachlorofluoropropanes, trichlorodifluoropropanes, dichlorotrifluoropropanes, or a mixture thereof, in the presence of a solid catalyst. The process generally comprises the following four steps: (i) providing a propane feedstock comprising trichlorodifluoropropanes and dichlorotrifluoropropanes, (ii) reacting the feedstock in a vapor phase reactor in the presence of HF and in the presence of a solid catalyst under conditions effective to form a product stream comprising HCFO-1233zd and unconverted starting materials, (iii) recovering or removing HCl and HF, and (iv) isolating HCFO-1233zd(E), HCFO-1233zd(Z), or both.
