実施例及び比較例の冷凍機油について、以下に示す夾雑物量の評価を実施した。すなわち、水分を1000質量ppmに調整した冷凍機油(初期酸価0.01mgKOH/g以下)30gと、表1〜3に示す冷媒(2,3,3,3−テトラフルオロプロペン冷媒(HFO−1234yf)又はジフルオロメタン冷媒(R32))30gと、空気90ml(0℃0.1MPa換算)と、触媒(鉄、銅、アルミの各線)とを200mlのステンレス製オートクレーブに封入した後、175℃に加熱して1週間保持して加熱試験に供した。その後、JIS K2276を参考に、加熱試験後の冷凍機油を孔径0.3μmのミリポアフィルターでろ過し、ろ過物及びフィルタをヘキサンで十分洗浄してヘキサン可溶分を取り除き、乾燥して得られたろ過物の重量から夾雑物量(mg/100g(冷凍機油))を算出した。夾雑物量が20mg/100g未満である場合をA、20mg/100g以上50mg/100g未満である場合をB、50mg/100g以上である場合又は3時間以上ろ過に時間を要してろ過不能と判断した場合をCとして評価した。結果を表2〜4に示す。
実施例の冷凍機油については、以下に示す酸価の評価を実施した。すなわち、まず、上記夾雑物量の評価と同様に冷凍機油を加熱試験に供した。次いで、JIS K2501に基づき、加熱試験後の冷凍機油の酸価を測定した。酸価が0.1mgKOH/g未満である場合をA、0.1mgKOH/g以上0.3mgKOH/g未満である場合をB、0.3mgKOH/g以上である場合をCとして評価した。結果を表5に示す。
