Description

【発明の詳細な説明】 DETAILED DESCRIPTION OF THE INVENTION

【0001】 [0001]

【産業上の利用分野】本発明は、フッ素系溶剤に関するものであり、より詳しくは物品表面からフラックス、油等の汚れ又は水分を除去するために用いるフッ素系溶剤に関する。 BACKGROUND OF THE INVENTION The present invention relates to a fluorine-based solvent, and more particularly to fluorine-based solvent used to remove the flux, dirt or moisture such as oil from the article surface.

【0002】 [0002]

【従来の技術】フラックス、油等の汚れ又は水分を除去するためには、不燃性、低毒性、安定性に優れるCCl BACKGROUND ART flux, in order to remove dirt or moisture such as oil is, CCl superior nonflammable, low toxicity, stability
2 FCClF 2 (以下、フロン113という)、または、フロン113とこれに可溶な溶剤との混合溶剤組成物が広く使用されている。 2 FCClF 2 (hereinafter, referred to as Freon 113), or a mixed solvent composition with Flon 113 and the soluble solvent which has been widely used. フロン113は、金属、プラスチック、エラストマー等の基材を侵さず、各種の汚れを選択的に溶解する等の特徴を有するため、各種精密機械部品や金属、プラスチック、エラストマー等からなる各種電子部品、光学部品などの洗浄には最適であった。 Freon 113, metal, plastic, without encroaching base material such as an elastomer, because it has characteristics such that selectively dissolves various soils, various electronic parts made of various precision machine parts, metal, plastic, elastomer, It was optimal for cleaning such as an optical component.

【0003】 [0003]

【発明が解決しようとする課題】従来使用されてきたフロン113は、種々の利点を有するにもかかわらず、化学的に極めて安定なため、対流圏での寿命が長く、拡散して成層圏に達し、ここで紫外線により光分解して塩素ラジカルを発生する。 Freon 113 has been conventionally used [0005], despite having various advantages, for chemically very stable, long life in the troposphere, diffuses to reach the stratosphere, here and photolysis by ultraviolet rays to generate chlorine radicals. この塩素ラジカルが成層圏オゾンと連鎖反応を起こし、オゾン層を破壊することから、その生産及び消費について規制が実施されている。 The chlorine radicals cause stratospheric ozone and chain reaction, since it destroys the ozone layer, regulations have been implemented for the production and consumption. 本発明は、以上の状況に鑑みてなされたものであり、従来のフロン113の優れた性質を損なうことなく、且つオゾン層破壊の心配がない新規なフッ素系溶剤を提供することを目的としている。 The present invention has been made in view of the above circumstances, and its object is to provide a novel fluorine-based solvents there is no risk of not, and ozone depletion impairing the excellent properties of conventional CFC 113 .

【発明の効果】本発明は、上記の構成を採用することにより、塩素原子を含まないため、オゾン層破壊の心配がなく、また、水素原子を含むため、大気中の水酸基ラジカルとの反応性が高く、対流圏で分解され易いため、温室効果が小さく、かつ、フロン113に替わる洗浄用溶剤、水切り乾燥用溶剤として有用な溶剤組成物の提供を可能にした。 According to the present invention, by adopting the configuration described above, since it does not contain a chlorine atom, there is no fear of the ozone layer, and since containing a hydrogen atom reactive with the hydroxyl radicals in the atmosphere is high and likely to be degraded in the troposphere, the greenhouse effect is small, and made it possible to provide a cleaning solvent, useful solvent composition as draining dry solvent to replace the CFC 113.
