Stabilized lubricant compositions and heat transfer compositions containing the same

A lubricant composition comprises a lubricant and a stabilizer. The stabilizer comprises a first epoxide group and a second functional group selected from the group consisting of (i) a second epoxide group; (ii) an aliphatic carbon-carbon multiple bond conjugated with a second carbon-carbon multiple...

Zusammenfassung:A lubricant composition comprises a lubricant and a stabilizer. The stabilizer comprises a first epoxide group and a second functional group selected from the group consisting of (i) a second epoxide group; (ii) an aliphatic carbon-carbon multiple bond conjugated with a second carbon-carbon multiple bond; (iii) an aliphatic carbon-carbon multiple bond conjugated with an electron withdrawing group; and (iv) an aliphatic carbon-carbon multiple bond conjugated with an aromatic group. A heat transfer composition comprises a lubricant composition as described above and a haloalkane, such as an iodoalkane (e.g., trifluoroiodomethane).
