Lubricating oil |
摘要 |
A lubricating oil suitable for use in alpha-olefin compressors and a high-pressure ethylene polymerization process is disclosed. The oil comprises a base fluid and a hindered C6-C30 alkyl 4-hydroxybenzoate. The hindered C6-C30 alkyl 4-hydroxybenzoate stabilizes the lubricating oil and does not interfere with the high-pressure alpha-olefin polymerization.
