Alkylated 5,6,7,8-tetrahydronaphthalenols as antioxidants in lubricating oils and greases

摘要

Alkylated 5,6,7,8-tetrahydronaphthalenols are effective antioxidants for fuel oils, lubricating oils, greases, plastics, and rubbers over a wide temperature range. Di- and tri-alkylated tetrahydronaphthalenols are especially effective, with the di- and tri-isopropylated materials being preferred.
