PURPOSE: To obtain the subject composition usable as substituting material of fluorinated hydrocarbon and having excellent properties as solvent, etc., with satisfying excellent properties of conventional fluorinated hydrocarbon, comprising one of R225ca, R225cb or R244ca and tetrafluoropropanol. n CONSTITUTION: 60-99wt.%, preferably 70-90wt.% one of 1,1-dichloro-2,2,3,3,3- pentafluoropropane (R225ca), 1,3-dichloro-1,2,2,3,3-pentafluoropropane (R225cb) or 1-chloro-2,2,3,3-tetrafluoropropane (R244ca) is mixed with 1-40wt.%, preferably 10-30wt.% 2,2,3,3-tetrafluoropropanol to afford the aimed composition. Said composition is able to be used in the same manner as conventional fluorinated hydrocarbon without necessity of steep amendment of conventional technique. n COPYRIGHT: (C)1991,JPO&Japio |
