Abstract:
Derivatives of nuclear coupled alkylphenols, that is nuclear carbon-to-carbon coupling, have higher activity as lubricating oil addition agents than the same derivatives of the parent alkylphenols. For example, sulfonamides or products of the Mannich Reaction derived from coupled p-alkylphenolsulfonyl chloride and an amine or coupled alkylphenol, amine and formaldehyde have higher activity than the same derivatives from the parent p-alkylphenol. Two, three, four, five, six and up to seven molecules of alkylphenol can be coupled through nuclear carbon-to-carbon coupling in the presence of a lower alkanoic acid (e.g., acetic acid) solution of potassium dichromate and manganese acetate.
Abstract:
Nitration of an alkene with dinitrogen tetroxide under oxidizing conditions forms the corresponding vicinal nitro-, nitratosubstituted alkane. Reaction of about 1-4 mols of the nitronitrato alkane with 1 mol of an alkylamine or alkylene polyamine forms alkane nitro-amines containing vicinal nitro-, aminonitrogen groups. The alkane nitro-amines are useful as surfactants, rust or corrosion inhibitors, flotation agents and as additives in petroleum products.
Abstract:
Derivatives of dimeric nuclear carbon-to-carbon coupled palkylphenol have higher activity as lubricating oil addition agents than the same derivative of present p-alkylphenol. For example, sulfonamide or methylene-imine (i.e., product of Mannich Reaction) derivatives of dimeric coupled p-alkylphenol sulfonylchloride or dimeric coupled alkylphenol are more active dispersants than the same sulfonamide or methyleneamine derivative of the parent alkylphenolsulfonyl chloride or palkylphenol. Such dimeric p-alkylphenols can be prepared by oxidative coupling in aqueous alkaline medium in presence of potassium ferricyanide.
