Abstract (en)
[origin: WO2015126584A1] The disclosure provides a process for the manufacture of trans 1-chloro3,3,3-trifluoropropene (trans 1233zd) by fluorinating 1230za and/or 240fa to a cis/trans mixture of 1233zd, separating the trans isomer followed by an isomerization of cis 1233zd to trans 1233zd in the fluorination step. The fluorination step is carried out in the gas phase or the liquid phase. The isomerization is carried out in the gas phase with a high surface area heterogeneous Cr catalyst, supported or unsupported.
