Description
本発明は、化学工業の技術分野に関し、特に、フッ化カルボニルの精製方法及び製造方法に関する。 The present invention relates to the technical field of the chemical industry, and more particularly to a method for purifying and producing carbonyl fluoride.
現在、半導体および液晶製造の分野において、パーフルオロカーボンをエッチングガス及びクリーニングガスとすることが多いが、上記ガスは、一般的に地球温暖化係数(GWP, Global Warming Potential)値が比較的高く、温室効果を低減するために、GWPの低い代替製品を開発する必要がある。
フッ化カルボニル(COF2)は、比較的低いGWPを有する半導体用エッチングガス、半導体用クリーニングガス、及び有機合成におけるフッ素化剤ないし重要な中間体である。
Currently, in the field of semiconductor and liquid crystal manufacturing, perfluorocarbon is often used as an etching gas and a cleaning gas, but the above gas generally has a relatively high global warming potential (GWP) value and is a greenhouse. In order to reduce the effect, it is necessary to develop alternative products with low GWP.
Carbonyl fluoride (COF 2 ) is an etching gas for semiconductors having a relatively low GWP, a cleaning gas for semiconductors, and a fluorinating agent or an important intermediate in organic synthesis.
現在、フッ化カルボニルの製造方法は、一般的に以下の4種類に分けられる。
1)一酸化炭素又は二酸化炭素をフッ素ガス、ジフルオロ銀(II)などのフッ素化剤と反応させる方法であり、当該方法は、爆発が起こりやすく、かつ高価な耐食性材料が必要であり、製造されたフッ化カルボニルの収率と純度が低い。
2)ホスゲン(COCl2)をフッ化水素、三フッ化アンチモン、三フッ化ヒ素、フッ化ナトリウムなどのフッ素化剤と反応させる方法であり、当該方法が使用する原料のホスゲンは、毒性の高い物質であり、かつ製造されたフッ化カルボニルの純度が低い。
3)トリフルオロメタンを酸素ガスと反応させる方法であり、当該方法は、反応条件が過酷であり、500℃以上の高温が必要である。
4)テトラフルオロエチレンを酸素ガスと反応させる方法であり、当該方法は、反応中において非常に大きな反応熱を生じ、爆発の危険性がある。
Currently, methods for producing carbonyl fluoride are generally classified into the following four types.
1) A method of reacting carbon monoxide or carbon dioxide with a fluorinating agent such as fluorine gas or difluorosilver (II), which is prone to explosion and requires an expensive corrosion-resistant material, and is manufactured. The yield and purity of carbonyl fluoride are low.
2) A method of reacting phosgene (COCl 2 ) with a fluorinating agent such as hydrogen fluoride, antimony trifluoride, arsenic trifluoride, and sodium fluoride. The raw material phosgene used in this method is highly toxic. It is a substance and the purity of the produced carbonyl fluoride is low.
3) A method of reacting trifluoromethane with oxygen gas, in which the reaction conditions are harsh and a high temperature of 500 ° C. or higher is required.
4) A method of reacting tetrafluoroethylene with oxygen gas, which generates a very large heat of reaction during the reaction and has a risk of explosion.
また、以上の異なるCOF2の製造方法と反応条件により製造されたフッ化カルボニルCOF2の粗生成物ガスは、一般的に、HCl、HF、ホスゲン(COCl2)、CF4、CO2、CO、H2O、N2O、空気中のN2及びO2などの不純物を含むことが多い。中でも、COF2の沸点は−84.57℃であり、CO2の沸点は−78.45℃であり、沸点が近く、沸点の差はたった約6℃と小さく、かつCOF2とCO2分子の物理的化学的性質、分子サイズは比較的近いため、通常の吸着法、精留法による精製分離は困難である。同時にそれらはいずれもアルカリ性物質と反応しやすいために、中和による分離も困難である。現在では、国内外でCOF2中のCO2の精製について、報告された特許はほとんどない。 Further, the crude product gas of carbonyl fluoride COF 2 produced by the above-mentioned different COF 2 production methods and reaction conditions is generally such as HCl, HF, phosgene (COCl 2 ), CF 4 , CO 2 , CO. , H 2 O, N 2 O, and often contains impurities such as N 2 and O 2 in the air. Among them, the boiling point of COF 2 is -84.57 ° C, the boiling point of CO 2 is -78.45 ° C, the boiling points are close, the difference between the boiling points is as small as about 6 ° C, and the COF 2 and CO 2 molecules Since the physical and chemical properties and molecular size of carbon dioxide are relatively close to each other, it is difficult to purify and separate them by ordinary adsorption methods and rectification methods. At the same time, they are all easy to react with alkaline substances, so they are difficult to separate by neutralization. At present, there are few patents reported on the purification of CO 2 in COF 2 at home and abroad.
上記の問題点に鑑みて、本発明の解決しようとする技術的課題は、製造されたフッ化カルボニルガスが高純度であるフッ化カルボニルの精製方法及び製造方法を提供することにある。 In view of the above problems, a technical problem to be solved by the present invention is to provide a method for purifying and producing carbonyl fluoride having a high purity of the produced carbonyl fluoride gas.
