炭化水素基置換数(m+n)=(芳香環の水素数)×(b1+b2+c)/[(炭化水素基の平均水素数)×a+b1+b2+c]
[ガスクロマトグラフィー(GC)測定条件]
ガスクロマトグラフィーは島津製作所製のGC-2010 Plusを使用して測定した。カラムはUltra ALLOY+-17、キャリアーガスは窒素ガスを使用した。測定温度条件は、50℃で2分間保持した後、毎分25℃ずつ100℃まで昇温、100℃からは毎分15℃で350℃まで昇温し、350℃で15分保持した。
[TG法による蒸発量の測定]
TG法による蒸発量は日立ハイテクノロジーズ社製ST7200RVを使用して測定した。キャリアーガスは空気(200ml/min)、試料容器はアルミニウム深皿パンを使用し、試料量は5mg、温度は250℃で、30分保持した時の各化合物の蒸発量(%)を測定した。
上記化合物1~10をそれぞれ0.5g、材質S45Cの50Φ凹面皿に秤量した。これを、200℃の恒温槽に静置し、2時間毎に恒温槽から取り出して重量測定を実施し、室温に戻した際の流動性を確認した。そして、室温での流動性を失った時間を薄膜寿命とした。本試験では、薄膜寿命25時間以上を合格として判定する。
OPTIMOL社のSRV-5を使用して、潤滑性を測定した。上部試験片は1/2インチSUJ2ボール、下部試験片はSK-5プレートを使用した。温度40℃、荷重50N、速度40mm/sで50秒の慣らし運転をした後に、温度40℃、荷重100N、速度40mm/sで600秒の本試験を実施して、摩擦係数(COF)を測定し、100Nでの平均COFを求めた。本試験では、平均COF0.150以下を合格として判定する。
JIS K2269(1987年)に基づいて、化合物1~10の流動点(℃)を測定した。本試験では、-20℃以下を合格として判定する。
40℃動粘度(mm2/s)を、JIS K 2283(2000年)に従って測定、算出した。
表1の結果から、本発明に関する実施例のナフチルフェニルエーテル化合物1~6および化合物10が、上述した蒸発量および薄膜寿命の両方の合格基準をすべて満たすことが示された。つまり、高温での蒸発損失が少なく、高温下における寿命も長いため、耐熱性に非常に優れることがわかった。通常は、化合物の分子量が小さくなれば蒸発量が多くなることが知られているが、本発明の化合物では、実施例1、2および7と比較例2を比較すると炭化水素基の炭素数が同一であっても蒸発量が抑えられていた。実施例2、4、6および7と比較例2を比較すると、同等の分子量であっても、蒸発量は抑えられていた。同等の動粘度を有する実施例3および比較例2を比較すると、本発明の構造を有する場合は、摩擦係数が優れることが分かった。実施例1~7と比較例3を比較すると、同じナフチルエーテルであっても炭化水素基(R1、および又はR2)の炭素数の違いにより、実施例1~7は良好な特性を示した。さらに、本発明の化合物では、低温流動性、潤滑性においても、従来潤滑剤として使用されている化合物と比べて遜色ない性能を備えていることも確認できた。実施例では40℃動粘度は比較例よりも高かったが、潤滑剤として使用することは可能であった。ゆえに、ナフチルフェニルエーテルの炭化水素基が炭素数6~28であり、炭化水素基置換数が1.0≦m+n≦3.0であるとき、耐熱性と低温流動性、潤滑性を併せ持つことが確認できた。
