1. A composition consisting of:
at least 99.5 mol %, based on a total molar amount of the composition, of cis and trans 1-chloro-3,3,3-trifluoropropene; and
coproducts,
wherein the coproducts consist of less than 0.3 mol %, based on the total molar amount of the composition, of 1,3,3,3-tetrafluoropropene and less than 0.1 mol %, based on the total molar amount of the composition, of 1,1,1,3,3-pentafluoropropane, and
wherein the composition is obtained at an exit of a reactor carrying out a process carried out in a liquid phase comprising less than 15% by weight of hydrofluoric acid (HF), based on the total weight of said liquid phase.
