Abstract
To replace compositions based on CFCs or CFHCs in applications for cleaning or drying solid surfaces (in particular defluxing), the invention proposes azeotropic or quasi-azeotropic compositions based on 1,1,1,2,3,4,4,5,5,5-decafluoropentane, 1,1,1,3,3-pentafluorobutane and, optionally, methanol.
