Abstract
Official abstract text for this publication.
What is disclosed is a liquid composition containing: 80 mol % to 99.9999 mol % of (Z)-1,2-dichloro-3,3,3-trifluoropropene (1223Z) and 0.0001 mol % to 20 mol % of (E)-1,2-dichloro-3,3,3-trifluoropropene (1223E). The liquid composition has small impact on the global environment and exerts azeotrope-like properties. Therefore, the composition of the liquid composition is not substantially changed even when the liquid composition is used in an open system or used for a long period. The composition of the liquid composition is also rarely changed even when the liquid composition is recovered by distillation. Therefore, the liquid mixture according to the present invention can be used suitably as a cleaning agent (a solvent).
First claim
Opening claim text (preview).
The invention claimed is: 1. An azeotrope (or azeotrope-like) composition comprising: (Z)-1,2-dichloro-3,3,3-trifluoropropene (1223Z) and (E)-1,2-dichloro-3,3,3-trifluoropropene (1223E). 2. The azeotrope (or azeotrope-like) composition as claimed in claim 1 , wherein the azeotrope (or azeotrope-like) composition contains 80 mol % to 99.9999 mol % of 1223Z and 0.0001 mol % to 20 mol % of 1223E. 3. The azeotrope (or azeotrope-like) composition as claimed in claim 1 , wherein the azeotrope (or azeotrope-like) composition contains 90 mol % to 99.9999 mol % of 1223Z and 0.0001 mol % to 10 mol % of 1223E. 4. A liquid composition comprising the azeotrope (or azeotrope-like) composition as claimed in claim 1 and at least one additional component. 5. The liquid composition as claimed in claim 4 , wherein the at least one additional component is contained in an amount of 10 ppm to 30 mass % relative to a total amount of the azeotrope (or azeotrope-like) composition. 6. A solvent for cleaning, comprising the azeotrope (or azeotrope-like) composition as claimed in claim 1 . 7. A solvent for cleaning, comprising the liquid composition as claimed in claim 4 . 8. A method for cleaning a cleaning target object, comprising bringing the azeotrope (or azeotrope-like) composition as claimed in claim 1 into contact with the cleaning target object. 9. A method for cleaning a cleaning target object, comprising bringing the liquid composition as claimed in claim 4 into contact with the cleaning target object.
