Title (EN) SOLVENT CLEANING PROCESS
(FR) PROCEDE DE NETTOYAGE PAR SOLVANTS
Abstract:
(EN) This invention relates to non-stabilized or at least only lightly stabilized n-propyl bromide-based solvent systems which are suitable for use in the presence of metals which normally and easily catalyze the dehydrobromination of brominated hydrocarbons, such as isopropyl bromide.
(FR) L'invention concerne des systèmes de solvants à base de bromure de n-propyle non stabilisé ou seulement peu stabilisé. Ces systèmes peuvent être utilisés en présence de métaux qui, normalement, catalysent facilement la déshydrobromation d'hydrocarbures bromés tels que le bromure d'isopropyle.
