PURPOSE:To obtain the subject composition, composed of a specific alcohol and 1,3-dichloro-1,2,2,3,3-pentafluoropropane, usable as a substitute fluorocarbon and having excellent characteristics as a solvent (especially a cleaning solvent), etc. CONSTITUTION:The above-mentioned composition, obtained by blending (A) any one of methanol, ethanol and isopropanol with (B) 1,3-dichloro-1,2,2,3,3- pentafluoropropane as essential components, usable as a substitute fluorocarbon while satisfying characteristics of conventional fluorocarbons, capable of simultaneously providing the same usage as that of a conventional single fluorocarbon due to small fluctuation of composition even in recycling and having great detergency. The amounts of the components are preferably as follows. 74-99wt.% component (B) and 1-26wt.% component (A) if the component (A) is the methanol; 74-99.5wt.% component (B) and 0.5-26wt.% component (A) if the component (A) is the ethanol and 77-99wt.% component (B) and 1-23wt.% component (A) if the component (A) is the isopropanol. |
