Description of the Related Art When cleaning parts such as precision equipment, optical equipment, and electronic equipment, a method of washing with pure water after treatment with an appropriate detergent according to contaminants is widely used. A drying step is required to remove the water present on the article surface. As a drying means, physical methods such as heating, decompression and centrifugation have been used for a long time, but in recent years, a drying method using a solvent which has a low energy cost and is capable of high speed drying has become popular. As a solvent, a liquid obtained by adding a surfactant or ethanol to trichlorotrifluoroethane (hereinafter referred to as CFC R113) is widely used.

摘されている。Fluorocarbon R113 has a lot of excellent properties such as nonflammability, low toxicity and low surface tension, and thus the demand has rapidly increased, but it is chemically stable and within the troposphere. It has been pointed out in recent years that it has a long lifespan and that it reaches the stratosphere, destroys the ozone layer, and increases harmful ultraviolet rays that reach the surface of the earth, resulting in a serious impact on the earth's ecosystem, including humankind.

を提供するものである。For this reason, there is an active international movement to regulate the production and consumption of CFCs such as CFC R113 having a high ozone depletion potential and to abolish them. In order to cope with such a situation, the present invention provides a novel draining solvent which does not destroy the ozone layer and has a draining ability comparable to that of conventional draining agents.
