産及び使用規制が実施されている。However, when isopropanol is used in the above-mentioned washing and drying method, there is a problem that accidents such as fire and explosion are likely to occur during the washing process because isopropanol is flammable. . In addition, isopropanol and 2,2,3,3,3-pentafluoropropanol have the disadvantage that their boiling points are high and their energy efficiency is poor. In addition, it has been pointed out that conventionally used chlorofluorocarbons, when released into the atmosphere, destroy the stratospheric ozone layer and, as a result, adversely affect ecosystems on the planet. And use regulations are in place.
