Abstract

PURPOSE:To obtain the subject azeotropic mixture useful as substitute for fluorocarbon or solvent, etc., which comprises 1,1-dichloro-2,2,3,3,3- pentafluoropropane; 1,3-dichloro-1,1,2,2,3-pentafluoropropane and specific compound. CONSTITUTION:(A) 5-47wt.%, preferably 27-38wt.% 1,1-dichloro-2,2,3,3,3- pentafluoropropane is mixed with (B) 3-42wt.%, preferably 4-15wt.% 1,3- dichloro-1,1,2,2,3-pentafluoropropane and (C) 43-79wt.%, preferably 53-63wt.% 1,1,2-trichloro-1,2,2-trifluoroethane (especially A = about 33wt.%, B = about 9wt.% and C = about 58wt.% as azeotropic composition) as essential ingredients. Said mixture is incombustible and has equivalent or better properties than the properties of conventional excellent fluorocarbon. Further, variation of composition in recycle does not arise because of existence of azeotropic point and thus said mixture is able to be used equally as conventional single fluorocarbon.

る。[Problems to be solved by the invention] R11, R12, and R113, which are particularly stable chemically, have a long life in the troposphere and diffuse into the stratosphere, where they are decomposed by sunlight and the generated chlorine radicals become ozone. Conventional regulations on the use of these fluorocarbons have been implemented because they are believed to cause a chain reaction and destroy the ozone layer. For this reason, there is active search for alternative fluorocarbons that are less likely to deplete the ozone layer in place of these conventional fluorocarbons.
