Abstract
The joint use of a C3 to C6 alkene compound comprising a sole double bond and of at least one molecular sieve for limiting or preventing the isomerization of trans-1-chloro-3,3,3-trifluoropropene to cis-1-chloro-3,3,3-trifluoropropene, and/or for limiting or preventing the degradation of trans-1-chloro-3,3,3-trifluoropropene. Also, a method for heating or cooling a fluid or a body, to a method for producing electricity and to a heat transfer installation.
