分野で広く用いられてきた。しかし、最近では、大気中
に放出されたフロンがIfcN圏においてオゾン層を破
壊するとともに、地球の温暖化、いわゆる「温室効果」
の原因となっているとして、特定種類のフロンの生産量
および消費量の削減の動きが強まっている. このため、オゾン層破壊、温室効果の恐れのないフロン
、すなわち分子内に塩素を含まず、比較的分解されやす
いフロンの開発が進んでいる. こうした中で、家庭用冷蔵庫、空調機、業務用小型冷蔵
庫、カーエアコンなどの冷媒として広く用いられてきた
フロン12 (ジクロロジフルオロメタン)の代替品と
して、フロン12と物性が類似したフロン134a (
1. 1. 1. 2−テトラフルオロエタン)が開発

いられてきたナフテン系鉱油やアルキルベンゼンとの相
溶性が悪く、蒸発器中での油戻り性の悪化やコンプレッ
サーの焼付け、異常振動などのトラブルを起こすため、
これと相溶性の良い冷凍機油の開発が求められている.
かかるフロン134aを冷媒とした冷凍機油に関しては
