Abstract
L'invention concerne un procédé pour stabiliser un pentafluoroéthane (F125) contenant des oléfines. Ce procédé consiste à ajouter au F125 un piège à radicaux et/ou un piège à acidité. Cet ajout permet de limiter les risques de dégradation du matériel fonctionnant avec des mélanges à base de F125.
