Abstract

Procédé de déshydratation d'un substrat contenant de l'eau, qui consiste à combiner ledit substrat avec un hydrofluorocarbone, tel qu'un hydrofluoroéther. Ledit procédé peut comporter l'étape consistant à éliminer l'eau de la composition combinée contenant le substrat et l'hydrofluoroéther, par ex, par vaporisation.
