Detergent composition, cleaning method, solvent composition, use thereof as solvent for oil, and oil composition containing same

Abstract

An object of the present invention is to provide a solvent and a detergent that have excellent basic properties as solvents or detergents, such as solubility, and that have a boiling point, flammability, toxicity, GWP, and ODP that are all within preferable ranges.To achieve the above object, the present invention provides a solvent composition or detergent composition comprising a hydrochlorofluoropropene represented by the formula: CX3CX═CX2, wherein each X is the same or different and is F or Cl, at least one X is F, and at least three X are Cl; the hydrochlorofluoropropene having an atmospheric pressure boiling point of 50° C. or higher.

Description

TECHNICAL FIELD[0001]The present invention relates to a detergent composition, a cleaning method, a solvent composition, use thereof as a solvent for oil, and an oil composition containing the same.BACKGROUND ART[0002]Various oils, including lubricating oils, such as silicone oil, fluorine-based oil, mineral-based oil, grease, and wax, are used for various applications. These oils can be singly applied to substrate surfaces or machine part surfaces in need of lubrication; however, in consideration of predetermined necessity or purpose, they are often used after being dissolved in solvents. For example, these oils are used when it is necessary to adjust viscosity etc., or used for the purpose of forming lubricating films of the oils on the surfaces to which the oils are applied.[0003]Moreover, those that have the same composition as these solvents and that are used to dissolve various oils for cleaning are particularly called detergents, cleaning solvents, etc.[0004]Some solvents or ...

AI Technical Summary

Benefits of technology

The present invention is about creating a solvent or detergent that has good properties as a solvent or detergent, such as being able to dissolve things easily. It also has a boiling point, flammability, toxicity, GWP, and ODP that are all within acceptable ranges.

Problems solved by technology

However, it is indicated that these conventional fluorine-based solvents or detergents, which are advantageous in non-flammability and low toxicity, have problems in terms of environmental destruction, such as possibility of ozone layer depletion and possibility of contribution to global warming.

In contrast, however, these environmentally friendly solvents have various problems such that they have low solubility; the solvents themselves are flammable; when they are mixed with second non-flammable solvents to reduce the flammability of the solvents themselves, it is necessary to adjust the composition ratio so that the mixed solvents are azeotropic; their boiling point is not suitable; and reduction in the global warming potential is not sufficient.
