Abstract

There are provided a solvent composition which is excellent in solubility of various organic substances and excellent in detergency and a drying property, and has no adverse effect on a global environment and is excellent in stability; a cleaning method using the solvent composition; a method of forming a coating film; a heat transfer fluid including the solvent composition; and a heat cycle system using the heat transfer fluid. A solvent composition including 1-chloro-2,3,3-trifluoro-1-propene and 1-chloro-3,3-difluoro-1-propyne, a cleaning method of bringing the solvent composition and an article into contact with each other, a method of dissolving a nonvolatile organic compound in the solvent composition to produce a coating film-forming composition and evaporating the solvent composition after applying the coating film-forming composition on an article to be coated, to form a coating film, a heat transfer fluid including the solvent composition, and a heat cycle system using the heat transfer fluid.

First claim

What is claimed is:

1. A coating film-forming composition comprising:
a solvent composition comprising 1-chloro-2,3,3-trifluoro-1-propene and 1-chloro-3,3-difluoro-1-propyne, and
a nonvolatile organic compound.

2. The coating film-forming composition according to claim 1 , wherein a proportion of a content of 1-chloro-3,3-difluoro-1-propyne to a total of a content of the 1-chloro-2,3,3-trifluoro-1-propene and a content of the 1-chloro-3,3-difluoro-1-propyne is 0.0001 to 0.1 mass %.

3. The coating film-forming composition according to claim 1 , wherein a proportion of a content of 1-chloro2,3,3-trifluoro-1-propene to a total amount of the solvent composition is 80 mass % or more.

4. The coating film-forming composition according to claim 1 , wherein the 1-chloro-2,3,3-trifluoro-1-propene consists of (Z)-1-chloro-2,3,3- trifluoro-1-propene and (E)-1-chloro-2,3,3-trifluoro-1-propene, and a proportion of a content of (Z)-1-chloro-2,3,3-trifluoro-1-propene to a total amount of 1-chloro-2,3,3-trifluoro-1-propene is 80 to 100 mass %.

5. A method of forming a coating film, comprising dissolving a nonvolatile organic compound in the coating film-forming composition according to claim to prepare a coating film-forming composition and evaporating the solvent composition after applying the coating film-forming composition on an article to be coated, to form a coating, film consisting of the nonvolatile organic compound.

6. The coating film-forming composition according to claim 1 , wherein the nonvolatile organic compound is at least one selected from a group consisting of a lubricant, an antirust, a moisture-proof coating agent, and an antifouling coating agent.
