Abstract

This invention provides a process for producing a fluoroolefin comprising reacting, in a vapor phase, a fluorinating agent and a chlorine-containing alkene or a chlorine-containing alkane in the presence of at least one catalyst selected from the group consisting of chromium oxide containing a Group 5 element and fluorinated chromium oxide containing a Group 5 element. According to the process of the present invention, the target fluoroolefin can be obtained with high starting material conversion and good selectivity.
