Abstract
Description
本発明は、パーフルオロヘプテンとヘキサメチルジシロキサンからなる共沸混合物様組成物、それを含む清浄化剤、熱媒体及びコーティング塗料に関する。 The present invention relates to an azeotropic mixture-like composition consisting of perfluoroheptene and hexamethyldisiloxane, a purifying agent containing the same, a heat medium and a coating coating material.
これまで、多くの産業分野において、クロロフルオロカーボン（ＣＦＣ）、ハイドロクロロフルオロカーボン（ＨＣＦＣ）およびハイドロフルオロカーボン（ＨＦＣ）などのフッ素系溶剤が、エアゾール噴射剤、冷媒、溶媒、清浄化剤、熱可塑性および熱硬化性発泡体用の発泡剤（発泡体膨張剤）、熱媒、ガス状誘電体、消火剤および鎮火剤、動力サイクル作動流体、重合媒体、微粒子除去流体、キャリア流体、バフ研磨剤、および置換乾燥剤をはじめとする広範囲の用途に使用されてきた。 To date, in many industrial sectors, fluorocarbon solvents such as chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs) have been used in aerosol propellants, refrigerants, solvents, cleaning agents, thermoplastics and heat. Foaming agents for curable foams (foam swelling agents), heat media, gaseous dielectrics, fire extinguishing agents and fire extinguishing agents, power cycle working fluids, polymerization media, particulate removal fluids, carrier fluids, buffing agents, and replacements. It has been used in a wide range of applications including desiccants.
しかしながら、ＣＦＣやＨＣＦＣはオゾン層破壊物質として知られており、また、ＨＦＣはオゾン層を破壊する危険はないものの、温室効果ガスとして地球温暖化に影響を及ぼすことから、より環境負荷の少ない、すなわち、オゾン破壊係数が０であり、地球温暖化係数が非常に低い代替組成物が求められている。 However, CFCs and HCFCs are known as ozone-depleting substances, and although HFCs do not have the risk of depleting the ozone layer, they have less environmental impact because they affect global warming as greenhouse gases. That is, there is a need for an alternative composition having an ozone depletion potential of 0 and a very low global warming potential.
このような代替組成物には、使用中又は回収時の蒸留中に分留されない定沸点特性および沸騰又は蒸発時に分留しない性質を有する共沸混合物が有用であることが知られている（例えば、特許文献１、特許文献２、特許文献３）。
しかしながら、特許文献１にも記載されているとおり、共沸混合物を形成するかどうかを理論的に予測することは不可能であり、種々の組み合わせについて、優れた特性を有する新規な共沸混合物の探索が続けられている。
For such alternative compositions, azeotropic mixtures having a constant boiling point property that is not fractionated during distillation during use or recovery and a property that is not fractionated during boiling or evaporation are known to be useful (eg,). , Patent Document 1,
However, as described in Patent Document 1, it is impossible to theoretically predict whether or not an azeotropic mixture will be formed, and a novel azeotropic mixture having excellent properties for various combinations will be formed. The search continues.
フッ素系溶剤の化合物の中でも、水素が全てフッ素に置換されたパーフルオロ化合物は、地球温暖化係数が大きいと思われていたため、これまで用いられることは少なかった。しかし、パーフルオロ化合物の中で、パーフルオロヘプテン（ペルフルオロヘプテン、以下ＰＦＨ）はオゾン破壊係数がゼロであり、地球温暖化係数も低いことから、各種の使用の提案がなされている（特許文献４、特許文献５）。 Among the compounds of fluorine-based solvents, perfluoro compounds in which all hydrogen is replaced with fluorine are considered to have a large global warming potential, and therefore have been rarely used so far. However, among the perfluoro compounds, perfluoroheptene (perfluoroheptene, hereinafter PFH) has a zero ozone depletion potential and a low global warming potential, so various uses have been proposed (patented). Document 4, Patent Document 5).
一方、シリコーン（ポリアルキルシロキサン、以下シリコーンと記載する。）、特に、ポリメチルシロキサンのような常温で液状のシリコーンオイル（以下、シリコーンオイルと記載する。）は、潤滑剤や離型剤その他多くの工業用途に使用されているほか、シリコーンを希釈溶剤中に溶解して、電子部品や医療器具の表面にコーティングし、製品の摺動性や撥水撥油性能を向上させる目的でも使用されている。
しかし、潤滑剤や離型剤としてシリコーンオイルを用いた際には、装置のメンテナンスや成形品の表面に残留した離型剤（シリコーンオイル）を除去するための洗浄・清浄化の必要が生じる。
On the other hand, silicone (polyalkylsiloxane, hereinafter referred to as silicone), in particular, silicone oil that is liquid at room temperature (hereinafter, referred to as silicone oil) such as polymethylsiloxane, is a lubricant, a mold release agent, and many others. In addition to being used in industrial applications, it is also used for the purpose of dissolving silicone in a diluting solvent and coating it on the surface of electronic parts and medical equipment to improve the slidability and water and oil repellency of products. There is.
However, when silicone oil is used as a lubricant or a mold release agent, it is necessary to maintain the device and to clean and clean the mold release agent (silicone oil) remaining on the surface of the molded product.
シリコーンオイル等のシリコーンを洗浄除去に使用する清浄化剤としては、ＨＣＦＣ類、塩素系溶剤、ジメチルシロキサン、臭素系溶剤等が使用されうるが、ＨＣＦＣはオゾン層を破壊するため、使用が禁止されている。塩素系溶剤および臭素系溶剤は毒性の点で問題があり、ジメチルシロキサンは引火点が低く引火の危険性が強い。一方で、引火点がなく、毒性が低く、さらにオゾン破壊係数がゼロで地球温暖化係数が低いＰＦＨは、シリコーンの溶解性が乏しいため、洗浄に使用することができない。
このため、シリコーンオイル等のシリコーンの洗浄除去に適したシリコーンの溶解性能を有し、かつ安全な溶剤が求められている。更に、シリコーンをコーティングする溶剤に
は、均一な薄膜を形成するために、低い表面張力や高い揮発性も求められる。
HCFCs, chlorine-based solvents, dimethylsiloxane, bromine-based solvents, etc. can be used as the cleaning agent that uses silicone such as silicone oil for cleaning and removal, but the use of HCFCs is prohibited because it destroys the ozone layer. ing. Chlorine-based solvents and bromine-based solvents have problems in terms of toxicity, and dimethylsiloxane has a low flash point and a high risk of ignition. On the other hand, PFH, which has no flash point, low toxicity, zero ozone depletion potential, and low global warming potential, cannot be used for cleaning because of its poor solubility of silicone.
Therefore, there is a demand for a safe solvent having a silicone dissolving performance suitable for cleaning and removing silicone such as silicone oil. Further, the solvent for coating silicone is required to have low surface tension and high volatility in order to form a uniform thin film.
本発明は、オゾン破壊や地球温暖化への影響が少なく、清浄化剤や熱媒体及び塗料等に適した、フッ素系溶剤の共沸混合物様組成物を提供することを目的とする。 An object of the present invention is to provide an azeotropic mixture-like composition of a fluorine-based solvent, which has little influence on ozone destruction and global warming and is suitable for a purifying agent, a heat medium, a paint, and the like.
本発明者らは、パーフルオロヘプテンとヘキサメチルジシロキサンを特定の比率で配合した組成物が共沸混合物様の性質を示し、熱媒体として使用できること、またシリコーンオイル等のシリコーンに対する溶解性が高く、清浄化剤、及び溶剤（キャリア流体）や、それを用いたコーティング塗料としての使用に適していることを見出して、本発明を完成するに至った。 The present inventors have shown that a composition containing perfluoroheptene and hexamethyldisiloxane in a specific ratio exhibits azeotropic mixture-like properties and can be used as a heat medium, and has solubility in silicone such as silicone oil. The present invention has been completed by finding that it is expensive and suitable for use as a cleaning agent, a solvent (carrier fluid), and a coating coating material using the same.

以下、本発明について、詳細に説明する。
本発明の共沸混合物様組成物は、パーフルオロヘプテン（ＰＦＨ）およびヘキサメチルジシロキサン（以下ＨＭＤＳ）から本質的になる。
Hereinafter, the present invention will be described in detail.
The azeotropic mixture-like composition of the present invention consists essentially of perfluoroheptene (PFH) and hexamethyldisiloxane (HMDS).
本発明において、ＰＦＨは、その構造異性体・立体異性体に特に制限はなく、単一の異性体でも、それらの異性体の混合物であってもよいが、直鎖タイプのＰＦＨを用いることがＨＭＤＳとの共沸組成におけるＨＭＤＳ組成比がより大きくできる可能性があるため好ましい。なかでも、シス若しくはトランス−パーフルオロ−３−ヘプテン又はその混合物が好ましく、特にトランス−パーフルオロ−３−ヘプテン又はそれを含む混合物、例えば、トランス−パーフルオロ−３−ヘプテンの割合が５０質量％以上であることが好ましく、６０質量％以上であればより好ましく、７０質量％以上であれば更に好ましく、８０質量％以上である異性体の混合物は、特に好ましい。 In the present invention, the structural isomer and stereoisomer of the PFH are not particularly limited, and may be a single isomer or a mixture of those isomers, but a linear type PFH may be used. It is preferable because the HMDS composition ratio in the azeotropic composition with HMDS may be larger. Of these, cis or trans-perfluoro-3-heptene or a mixture thereof is preferable, and in particular, the proportion of trans-perfluoro-3-heptene or a mixture containing it, for example, trans-perfluoro-3-heptene is 50% by mass. The above is preferable, 60% by mass or more is more preferable, 70% by mass or more is further preferable, and a mixture of isomers of 80% by mass or more is particularly preferable.
当該技術分野で認められているように、共沸組成物は、２つ以上の異なる成分の混合物であり、それは、所与の圧力下で液体形態にあるとき、実質的に一定温度で沸騰し、その温度は、個々の成分の沸騰温度より高いか又は低く、かつ、それは沸騰中の全体液体組成と本質的に同一である蒸気組成を提供する（例えば、Ｍ．Ｆ．Ｄｏｈｅｒｔｙ ａｎｄ Ｍ．Ｆ．Ｍａｌｏｎｅ、Ｃｏｎｃｅｐｔｕａｌ Ｄｅｓｉｇｎ ｏｆ Ｄｉｓｔｉｌｌａｔｉｏｎ Ｓｙｓｔｅｍｓ、ＭｃＧｒａｗ−Ｈｉｌｌ（ＮｅｗＹｏｒｋ）、２００１年、１８５〜１８６、３５１〜３５９頁を参照）。 As recognized in the art, an azeotropic composition is a mixture of two or more different components, which, when in liquid form under a given pressure, boils at a substantially constant temperature. , Its temperature is above or below the boiling temperature of the individual components, and it provides a vapor composition that is essentially identical to the overall liquid composition during boiling (eg, MF Doherty and MF). . Malone, Conceptual Design of Distillation Systems, McGraw-Hill (NewYork), 2001, 185-186, pp. 351-359).
この時、液の組成を共沸混合液の組成に近い範囲で、種々変化させて定圧の気液平衡関係を測定してみると、共沸混合物の沸点が極大又は極小となることが知られている。 At this time, when the vapor-liquid equilibrium relationship of constant pressure is measured by changing the composition of the liquid in a range close to the composition of the azeotropic mixture, it is known that the boiling point of the azeotropic mixture becomes maximum or minimum. ing.
従って、共沸組成物の本質的な特徴は、所与の圧力で、液体組成物の沸点が固定されていること、かつ、沸騰中の組成物の上方の蒸気の組成が、本質的に沸騰中の全体液体組成物の組成である（すなわち、液体組成物の成分の分留が起こらない）ことである。共沸組成物が異なる圧力で沸騰にかけられるとき、共沸組成物の各成分の沸点および質量百分率の両方が変わる場合があることもまた当該技術分野で認められている。従って、共沸組成物は、成分間に存在する特有の関係の観点から又は成分の組成範囲の観点から、或いは指定圧力での固定沸点によって特徴付けられる組成物の各成分の正確な質量百分率の観点から、定義されてもよい。 Therefore, the essential characteristics of the azeotropic composition are that, at a given pressure, the boiling point of the liquid composition is fixed, and the composition of the vapor above the composition in boiling is essentially boiling. It is the composition of the whole liquid composition inside (ie, fractional distillation of the components of the liquid composition does not occur). It is also acknowledged in the art that when the azeotropic composition is boiled at different pressures, both the boiling point and the mass percentage of each component of the azeotropic composition may change. Thus, the azeotropic composition is the exact mass percentage of each component of the composition characterized in terms of the unique relationships that exist between the components, in terms of the composition range of the components, or by the fixed boiling point at a specified pressure. From a point of view, it may be defined.
本発明の目的のためには、本発明の共沸混合物様組成物は、共沸組成物のように挙動する（すなわち、定沸点特性又は沸騰若しくは蒸発時に分留しない傾向を有する）組成物を意味する。それ故に、沸騰中や蒸発中に、気液組成は、それらが仮に変化する場合でも、最小限の程度または無視できる程度しか変化しない。これは、沸騰中や蒸発中に、気液組成がかなりの程度変化する非共沸混合物様組成物とは対照的である。 For the purposes of the present invention, the azeotropic mixture-like compositions of the present invention behave like azeotropic compositions (ie, have constant boiling characteristics or tend not to fractionate during boiling or evaporation). means. Therefore, during boiling and evaporation, the gas-liquid composition changes to a minimal or negligible degree, even if they change. This is in contrast to non-azeotropic mixture-like compositions, where the gas-liquid composition changes to a large extent during boiling and evaporation.
また、本発明の共沸混合物様組成物は、実質的に温度差なしの液相線および気相線を示す。すなわち、所与の圧力下での液相温度と気相温度との差は小さな値であろう。本発明では、（最低共沸点を基準として）２℃以下の液相温度との差の組成物は共沸混合物様であると考える。 In addition, the azeotropic mixture-like composition of the present invention exhibits a liquid phase line and a gas phase line with substantially no temperature difference. That is, the difference between the liquid phase temperature and the gas phase temperature under a given pressure will be small. In the present invention, the composition having a difference from the liquid phase temperature of 2 ° C. or lower (based on the minimum azeotropic boiling point) is considered to be azeotropic mixture-like.
さらに、あるシステムの相対揮発度が１.０に近づくときに、そのシステムが共沸組成
物又は共沸混合物様組成物を形成すると定義されることはこの分野で周知のことである。相対揮発度は、成分１の揮発度対成分２の揮発度の比である。蒸気中のある成分のモル分率対液体中のそれの比がその成分の揮発度である。
Moreover, it is well known in the art that when the relative volatility of a system approaches 1.0, the system is defined to form an azeotropic composition or an azeotropic mixture-like composition. The relative volatility is the ratio of the volatility of component 1 to the volatility of
本発明の共沸混合物様組成物は、必要に応じて安定化剤として、ニトロアルカン類、エポキシド類、フラン類、ベンゾトリアゾール類、フェノール類、アミン類又はホスフェイト類を１種又はそれ以上含んでもよく、その配合量は、共沸混合物様組成物に対して０．０１〜５質量％、好ましくは０．０５〜０．５質量％である。 The azeotropic mixture-like composition of the present invention may contain one or more nitroalkanes, epoxides, furans, benzotriazoles, phenols, amines or phosphates as stabilizers, if necessary. The blending amount thereof is often 0.01 to 5% by mass, preferably 0.05 to 0.5% by mass, based on the azeotropic mixture-like composition.
本発明の共沸混合物様組成物はまた、本発明の特徴を損なわない範囲で、必要に応じて、（フッ素含有アルコール以外の）アルコール類、ケトン類、エーテル類、エステル類、炭化水素類、アミン類、グリコールエーテル類、シロキサン類などの他の成分を含んでもよい。 The co-boiling mixture-like composition of the present invention also contains alcohols (other than fluorine-containing alcohols), ketones, ethers, esters, hydrocarbons, as required, as long as the characteristics of the present invention are not impaired. It may contain other components such as amines, glycol ethers and siloxanes.
本発明の共沸混合物様組成物は、地球温暖化係数（ＧＷＰ）が約１００以下、好ましくは５０以下、より好ましくは１０以下である。ここで、本発明におけるＧＷＰは、世界気象機関の報告書である「Scientific Assessment of Ozone Depletion, 2002」に定義されるものである。 The azeotropic mixture-like composition of the present invention has a global warming potential (GWP) of about 100 or less, preferably 50 or less, and more preferably 10 or less. Here, the GWP in the present invention is defined in the report of the World Meteorological Organization, "Scientific Assessment of Ozone Depletion, 2002".

本発明の共沸混合物様組成物においては、ＨＭＤＳ組成比が大きい範囲を選択することが、シリコーン溶解性が大きくなるため好ましく、また、ＰＦＨよりＨＭＤＳの方が一般的に安価であるため、経済的な面からも好ましい。
The azeotropic mixture-like composition containing PFH and HMDS of the present invention preferably has a boiling point in the range of 68 to 70 ° C. under atmospheric pressure, and the blending amount thereof is PFH: HMDS = 70 to 97% by mass. : 3.0 to 30% by mass, preferably HMDS: 5 to 25% by mass, more preferably 10 to 25% by mass, more than 10% by mass and 25% by mass or less, especially 11% by mass. The range of 20% by mass or less is particularly preferable.
In the azeotropic mixture-like composition of the present invention, it is preferable to select a range in which the HMDS composition ratio is large because the silicone solubility is high, and HMDS is generally cheaper than PFH, which is economical. It is also preferable from the aspect of the above.

[Measurement result]
The change in boiling point (equilibrium reflux boiling point) of the mixture consisting of PFH and HMDS is shown in FIG.
ＰＦＨおよびＨＭＤＳよりなる混合物は、共沸混合物様組成物を形成するので、熱媒体としての使用に適している。通常熱媒体は密閉系で使用されるが、場合によっては開放されるケースもある。その際、非共沸混合物では組成変化が生じるが、共沸混合物では組成変化が生じないので、組成は一定のままでありその能力変化は生じず、使用機器への影響がない。 The mixture consisting of PFH and HMDS forms an azeotropic mixture-like composition and is therefore suitable for use as a heat medium. Usually, the heat medium is used in a closed system, but in some cases, it is opened. At that time, the composition of the non-azeotropic mixture changes, but the composition of the azeotropic mixture does not change. Therefore, the composition remains constant and its capacity does not change, and there is no effect on the equipment used.
