UNSULFURIZED, ALKALI METAL-FREE, ADDITIVE FOR LUBRICATING OILS |
摘要 |
An unsulfurized, alkali metal-free, detergent-dispersant composition having from 40% to 60% alkylphenol, from 10% to 40% alkaline earth alkylphenate, and from 20% to 40% alkaline earth single aromatic-ring alkylsalicylate. This composition may have an alkaline earth double aromatic-ring alkylsalicylate as long as the mole ratio of single-ring alkylsalicylate to double aromaticring alkylsalicylate is at least 8:1. This composition may be produced by the three-step process involving neutralization of alkylphenols, carboxylation of the resulting alkylphenate, and filtration of the product of the carboxylation step.
