Sulfurized phenolic antioxidant tongues, preparation methods thereof, and petroleum products containing the same |
| abstract |
The present invention relates to phenols which are substantially liquid, free of chlorine, and useful as sulfur crosslinked antioxidants, and more particularly, are effective antioxidant (s) and improved elastomers in lubricants and liquid organic fuels without causing excessive copper corrosion. It relates to the preparation of a hindered phenol composition which is substantially liquid, free of chlorine and crosslinked with sulfur, using 1-propanol as the reaction solvent which has seal compatibility. The present invention also includes lubricating oils and liquid organic fuels containing the antioxidant additives of the present invention and includes methods for preventing oxidation in lubricating oils or liquid organic fuels used in machines such as internal combustion engines. |
