Abstract
Description
本発明の冷凍機用潤滑油組成物に含有される混合エステルは、混合アルコールと炭素数5〜10の飽和モノカルボン酸とから得られ、該混合アルコールが1〜90モル%のネオペンチルグリコール、10〜80モル%のペンタエリスリトール、および0.01〜20モル%のジペンタエリスリトールからなり、かつ以下の関係式:
本発明の冷凍機用潤滑油組成物は、上記混合エステルを主成分として含有し、必要に応じて、混合エステル以外の他のエステル、添加剤などを含有し得る。「主成分」の具体的な量は、冷凍機用潤滑油組成物全体を基準として、50質量%以上、好ましくは70質量%以上、より好ましくは90質量%以上である。100質量%であってもよい。
本発明の冷凍機作動流体は、上記冷凍機用潤滑油組成物と、非塩素系フロン冷媒とからなる。冷凍機用潤滑油組成物と非塩素系フロン冷媒との配合比に特に制限はないが、好ましくは、質量比で冷凍機用潤滑油組成物:非塩素系フロン冷媒が10:90〜90:10の割合である。非塩素系フロン冷媒の配合比が上記範囲より高いと、得られる冷凍機作動流体の粘度が低下し、潤滑不良を起こすおそれがある。上記範囲より低い場合は、得られる冷凍機作動流体を機器に用いた場合に冷凍効率が低下するおそれがある。
本発明の冷媒圧縮式冷凍装置は、圧縮機、凝縮器、膨張機構、および蒸発器を備え、冷凍装置内の冷媒である上記冷凍機作動流体が、これらを循環するように構成されている。この冷凍装置は、さらに乾燥器を含み得る。このような冷凍装置としては、例えば、ルームエアコン、パッケージエアコンなどの空調機器;冷蔵庫、冷凍庫などの低温装置;産業用冷凍機;およびハイブリッドカー、電気自動車などのカーエアコンなどが挙げられる。
<動粘度および粘度指数> JIS K−2283に準拠して、キャノン−フェンスケ粘度計を用いて、40℃および100℃における動粘度を測定し、粘度指数を算出する。
<酸価> JIS C−2101に準拠して測定する。
<水酸基価> JIS K−0070に準拠して測定する。
<色相> JOCS 2.2.1.4−1996に準拠して測定する。
<体積抵抗率> JIS C−2101に準拠して、25℃における体積抵抗率(TΩ・m)を測定する。
<流動点> JIS K−2269に準拠して測定する。
<長期低温試験> 水分量を100ppm以下に調整した試料400gをスチール製の角缶に入れ、−28℃の低温庫に1000時間放置し、結晶が析出しているかどうか目視にて確認する。
<二相分離温度> 0.6gの試料(エステル)と、2.4gの冷媒R−134aとを、ドライアイスを入れたエタノール浴で冷却した肉厚パイレックス(登録商標)チューブ(全長300mm、外径10mm、内径6mm)に封入し、1℃/分の割合で昇温または冷却し、高温および低温での二相分離温度を−70℃〜+80℃の範囲で目視により測定した。
<シールドチューブ試験> ガラス管に、予め水分量を200ppm以下に調整した試料を10g、フロンR−410Aを5g、および長さ10mmの鉄、銅、およびアルミの金属片を各1枚ずつ封入し、密閉する。これを、175℃にて14日間加熱した後、金属片を除いたフロン含有試料の酸価および色相(APHA)を測定する。
<Falex摩擦試験> ASTM D−2670に準拠して、試料中にR−134aを150mL/分の割合で吹き込みつつ、Falex摩擦試験を行った。試料温度を100℃とし、150ポンドの荷重で1分間試運転した後に、250ポンドの荷重下で2時間運転し、運転終了後のピンの摩耗量を測定する。
温度計、窒素導入管、撹拌機および冷却管を取り付けた1リットルの4つ口フラスコに、表1に示す混合アルコールと飽和モノカルボン酸とを、混合アルコールの水酸基と飽和モノカルボン酸のカルボキシル基とが当量比で1:1.1の割合となるように仕込み、窒素気流下、220℃で反応水を留去しつつ常圧で反応を行った。反応中、水酸基価をモニターし、2.0mgKOH/gを下回った時点で反応を停止した。その後、1〜5kPaの減圧下でストリッピングを行い、未反応のカルボン酸を1時間かけて除去した。得られた反応混合物に水酸化カリウム水溶液を加えて水洗した。水洗は、排水のpHが中性となるように5回繰り返した。次いで、得られたエステル層を100℃、1kPaの条件下で減圧脱水し、酸性白土およびシリカ−アルミナ系の吸着剤をそれぞれ、理論上得られるエステル量の1.0質量%となるように添加して吸着処理した。吸着処理温度、圧力、および吸着処理時間は、それぞれ100℃、lkPa、および3時間とした。その後、1ミクロンのフィルターを用いてろ過を行い、エステル(エステルA)を得た。得られたエステルAについて、上記の方法により、40℃および100℃における動粘度を測定した。結果を表1に示す。
表1に示す混合アルコールおよび飽和モノカルボン酸を用いたこと以外は、実施例1と同様に操作して、エステル(エステルB〜G)を得た。各エステルについて、上記の方法により、40℃および100℃における動粘度を測定した。結果を表1に併せて示す。
表1に示す混合アルコールおよび飽和モノカルボン酸を用いたこと以外は、実施例1と同様に操作して、エステル(エステルH〜L)を得た。各エステルについて、上記の方法により、40℃および100℃における動粘度を測定した。結果を表1に併せて示す。
合成例1で得られたエステルAを用いて潤滑油を調製した(潤滑油1とする)。潤滑油1について、上記の方法により、40℃および100℃における動粘度、粘度指数、色相、酸価、水酸基価、体積抵抗率、流動点、二相分離温度の測定、長期安定性試験、シールドチューブ試験、およびFalex試験を行った。結果を表2に示す。
合成例2〜7で得られたエステル(エステルB〜G)を用いて潤滑油を調製した(潤滑油2〜7とする)。各潤滑油について、上記の方法により、40℃および100℃における動粘度、粘度指数、色相、酸価、水酸基価、体積抵抗率、流動点、二相分離温度の測定、長期安定性試験、シールドチューブ試験、およびFalex試験を行った。結果を表2に併せて示す。
比較合成例1〜5で得られたエステル(エステルH〜L)を用いて潤滑油を調製した(潤滑油8〜12とする)。各潤滑油について、上記の方法により、40℃および100℃における動粘度、粘度指数、色相、酸価、水酸基価、体積抵抗率、流動点、二相分離温度の測定、長期安定性試験、シールドチューブ試験、およびFalex試験を行った。結果を表2に併せて示す。
