Abstract
A process for isomerising a (hydrohalo)fiuoroalkene, the process comprising contacting the (hydrohalo)fluoroalkene with a catalyst comprising an unsupported Lewis acid, a chromia-containing catalyst containing at least one additional metal, an alumina, a supported liquid catalyst, and mixtures thereof.

A process for making a (hydrohalo) fluoroalkene composition comprising a level of a Z isomer of (hydrohalo) fluoroalkene enhanced beyond the level of the Z isomer when the (hydroholo)fluoroalkene was formed, or beyond the kinematic equilibrium level of the Z isomer, comprising the step of using a catalyst comprising an unsupported Lewis acid, a chromia-containing catalyst containing at least one additional metal, an alumina, a supported liquid catalyst, and mixtures thereof.
