本発明は、代替フロンとして使用できるとともに溶剤等

様組成物に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a novel fluorinated hydrocarbon azeotrope-like composition that can be used as a CFC substitute and has excellent properties as a solvent and the like.

クロロジフロロメタン（Ｒ１２）が使われている。[Prior art] Fluorinated hydrocarbon compounds (hereinafter simply referred to as fluorocarbons) are
Many of them are less toxic and chemically stable, and various types of chlorofluorocarbons with different standard boiling points are available.Using these properties, 1.1.2-trichloro-1,2-trichloro-1,2 can be used as a solvent, blowing agent, propellant or refrigerant. , 2-trifluoroethane (R113), trichloromonofluoromethane (R11) is used as a blowing agent, and dichlorodifluoromethane (R12) is used as a propellant or refrigerant.

め、これらの従来のフロンに代わり、オゾン層を破壊し
にくい代替物質の探索が活発に行なわれている。[Problems to be solved by the invention] When fully halogenated hydrocarbons such as CFCs R11, R12, and R113, which are particularly chemically stable, reach the stratosphere, chlorine radicals decomposed by sunlight cause a chain reaction with ozone. Since these substances are believed to destroy the ozone layer, regulations have been implemented on the production of these specific fluorocarbons. Therefore, in place of these conventional fluorocarbons, there is active search for alternative substances that are less likely to deplete the ozone layer.
本発明は、従来のフロンの使用量を低減し、かつ該物質
が有している優れた特性を満足しながら代替物質として
使用できる新規なフロン組成物を提供することを目的と
するものである。An object of the present invention is to provide a new fluorocarbon composition that can be used as a substitute material while reducing the amount of conventional fluorocarbons used and satisfying the excellent properties of the material. .
［課題を解決するための手段］
本発明は、メタノール、エタノール、１−プロパノール

The present invention relates to an azeotrope-like composition comprising trichloro-2,2-difluoroethane (R122).
本発明の組成物は、共沸組成物と極めて類似した性状を
示す上、洗浄溶剤としては従来のＲ１１３単体より洗浄
力が高いため、Ｒ１１３代替として極めて有用なもので
ある。また、近年地下水汚染やオゾン層破壊等環境破壊
の点より使用規制の唱われているｉ、ｔ、１−トリクロ
ロエタン代替としてもきわめて有用である。The composition of the present invention exhibits properties very similar to those of azeotropic compositions, and has higher detergency as a cleaning solvent than conventional R113 alone, so it is extremely useful as a substitute for R113. It is also extremely useful as a substitute for i, t, 1-trichloroethane, whose use has been regulated in recent years due to environmental damage such as groundwater contamination and ozone layer destruction.
一般に、複数の化合物をン昆合した組成物を使用する場

する性状が変化することが懸念される。また、特に溶剤
として使用する場合、この組成変化ならびに初期の混合
比率は、洗浄性能・溶解性能に直結する最重要な事項で
ある。例えば本発明の様に、比較的低溶解性を有する弗
素系炭化水素と比較的高溶解性を有するアルコールとの
混合組成物の場合には、アルコール添加量が少ない場合
は洗浄能力不足となり、逆に多い場合は被洗浄物を侵す
という問題が上がってくる。Generally, when a composition containing a plurality of compounds is used, there is a concern that the properties of the composition may change due to changes in the composition during use. Moreover, especially when used as a solvent, this change in composition and the initial mixing ratio are the most important matters that are directly connected to cleaning performance and dissolution performance. For example, in the case of a mixed composition of a fluorine-based hydrocarbon with a relatively low solubility and an alcohol with a relatively high solubility, as in the present invention, if the amount of alcohol added is small, the cleaning ability will be insufficient, and vice versa. If there is a large number of such substances, the problem arises that they attack the objects to be cleaned.
そこで本発明では、組成変化を防ぐ共沸様の挙動を呈し
、かつ前述の問題点を解決可能な最適な混合割合を見い
だした。Therefore, in the present invention, we have found an optimal mixing ratio that exhibits azeotrope-like behavior that prevents compositional changes and that can solve the above-mentioned problems.
更に、リサイクルしても、本発明の組成物は組成変動が
少ないことより、従来の単一フロン同様の使用方法が可
能であり従来技術の大幅な変更を要しない等の利点を有
している。Furthermore, even after recycling, the composition of the present invention has the advantage that it can be used in the same manner as conventional single fluorocarbons, and does not require major changes in conventional technology, since the composition of the composition does not change much. .
