LUBRICATING OIL FOR REFRIGERATORS USING R-134A COOLING AGENT |
| 摘要 |
Pentaerysritol is reacted with mono-aliphatic acid of C5-C9 in catalyst and solvent, and then catalyst, solvent and un-reacted monoaliphatic acid are eliminated to obtain a refrigerant oil(R-134a) that is added to alkybenzotriazol. Accordingly, the refrigerant oil improves the attrition irrelevant to influence of thermal and oxidation stability.
