PURPOSE:To obtain the subject composition composed of a highly fluorinated hydrocarbon as a base, having azeotropic behavior or a behavior close to azeotropic behavior and excellent characteristics as a detergent comprising decafluoropentane and 3-methylpentane. CONSTITUTION:70-99wt.% 1,1,1,2,3,4,4,5,5,5-decafluoropentane is mixed with 30-1wt.% 3-methylpentane and optionally preferably 0.05--0.5wt.% stabilizer such as a nitroalkane to give the objective composition. |
