Abstract
【解決手段】カーボネート化合物と2価アルコールとを反応させて得られた中間体を、さらに1価アルコールを反応させて得られるポリカーボネート化合物を基油として含有する冷凍機油として使用される。これにより、相溶性が高く、低温特性があり、さらに、冷凍機油としての化学的安定性、及び、潤滑性、並びに、電気特性を備えた冷媒用組成物を提供することができる。
【選択図】なし
Description
実施例1としては、ジメチルカーボネートと3−メチル−1,5−ペンタンジールとを反応させて得られた中間体を、さらに、3−メチル−1−ブタノールとを反応させて得られた冷凍機油としてカーボネート油を合成した。
比較例1としては、冷凍機油として、ポリオールエステル油を使用し、比較例2としては、冷凍機油として、ポリビニルエーテル油を使用し、比較例3としては、冷凍機油として、ナフテン系鉱物油を使用し、比較例4としては、冷凍機油として、アルキルベンゼン油を使用した。
実施例1〜12、及び、比較例1〜4に対して、以下の表1に示す試験を実施した。
上記試験項目のうち、相溶性は、試験条件として、冷媒R−23を使用し、冷凍機油/冷媒混合比率を55/45(wt%)とし、温度を−40℃として試験を行った。
上記試験項目のうち、低温特性は、(1)所定量の水分量を調製した冷凍機油と、冷媒とを試験管(シールドチューブ)にはかりとり、封入し、(2)試験管を規定の温度まで冷却し、24時間静置し、(3)静置後、溶液の分離状態や流動性を観察し、冷凍機油と冷媒の相溶性を評価した。なお、評価方法として、〇:良い、×:悪い、で評価した。
上記試験項目のうち、ファレックス耐荷重試験は、1112Nで5分間ナラシ運転を行った後、FALEX社製の自動加重装置により加重していき、焼付の生じた荷重を焼付荷重とした。
上記試験項目のうち、化学的安定性は、(1)試験管に、所定量の水分量を調製した冷凍機油と、冷媒と、金属触媒とを封入し、175℃で14日間加熱し、(2)加熱後、冷凍機油の安定性と金属の影響を確認し、冷凍機油と冷媒の化学的安定性を評価した。なお、評価方法として、〇:良い、×:悪い、で評価した。
上記の試験方法にて行った試験結果を表2に示す。
Claims (3)
- 冷凍機油として請求項1と異なる組成物を少なくとも1種類以上含有してなることを特徴とする冷媒用組成物。
- 極圧剤、油性剤、酸化防止剤、酸捕捉剤及び消泡剤の中から選ばれる少なくとも1種の添加剤を含んでなる請求項1又は2に記載の冷媒用組成物。
