Abstract
A mixed solvent composition comprising dichloropentafluoropropane and at least one component selected from the group consisting of 1,1,1,2,3,4,4,5,5,5-decafluoropentane and perfluorohexane as the essential components, or a mixed solvent composition comprising dichloropentafluoropropane, an alcohol and at least one component selected from the group consisting of 1,1,1,2,3,4,4,5,5,5-decafluoropentane and perfluorohexane.
Claims6
A mixed solvent composition, which consists essentially of dichloropentafluoropropane and 1,1,1,2,3,4,4,5,5,5,-decafluoropentane as essential components.
A mixed solvent composition, which is a mixture comprising from 45 to 60% by weight of 3,3-dichloro-1,1,1,2,2-pentafluoropropane and from 40 to 55% by weight of 1,1,1,2,3,4,4,5,5-decayluoropentane, and wherein said mixed solvent composition varies only within a range of .+-.2% with repeated distillation-condensation.
A mixed solvent composition, which is mixture comprising from 30 to 50% by weight of 1,3-dichloro-1,1,2,2,3-pentafluoropropane and from 50 to 70% by weight 1,1,1,2,3,4,4,5,5,5-decafluoropentane, and wherein said mixed solvent composition varies only within a range of .+-.2% with repeated distillation-condensation.
