Abstract:
A multipurpose additive for lubricating oils of antioxidant, antithickening, anticorrosion and detergent properties comprising a sulfurized Group II metal nitrated alkylphenolate prepared by (1) contacting an alkylphenol with a nitrating agent to form nitrated alkylphenol, (2) treating the nitrated alkylphenol with a Group II metal oxide, hydroxide or alkoxyalkoxide to form the Group II metal salt of nitrated alkylphenol, (3) treating the Group II metal salt with sulfur to form the sulfurized reaction product of the Group II metal salt of a nitrated alkylphenol.
Abstract:
Reaction mixtures of alkoxylated diphenyl monohalo phosphates and alkoxylated phenyl dihalo phosphates are used as additives, particularly as surface ignition suppressors in motor fuels. The mixtures are especially useful since they can be used in the unresolved form.
