    Abstract: Polymethylene polyamine sulfonamides of alkyl-substituted phenolic sulfonic acids wherein the alkyl-substituent has a molecular weight within the range of 400 to 3000 are novel compounds soluble in mineral hydrocarbon oils of the lubricating oil range and as solutes therein are ashless addition agents imparting to the solution a combination of anti-oxidant and detergency-dispersancy properties useful in the lubrication of internal combustion engines. Illustrative of such sulfonamides are mono- and disulfonamides of hexamethylene diamine, tetraethylene pentamine, 2,6-di(aminoethyl) pyridine and N,N''di(aminopropyl) piperazine with 4-alkylphenolic sulfonic acids such as 4-alkyl-1-hydroxyphenyl, 4,4''-dialkyl-1,1''-dihydroxy2,2''-biphenyl, 4-alkyl-1-alkoxyphenyl or 2-tri- and tetra-(4''alkyl-1-hydroxybenzyl)-substituted 4-alkyl-1-hydroxyphenyl sulfonic acid chlorides.

    Abstract: Novel sulfonamides soluble in C6 and higher alkanes and lubricating oils, which are antioxidants therefor preventing oxidative thickening of the oil, are obtained from nuclear carbon-to-carbon dimers to heptemers of 85 to 3,000 MW alkylsubstituted phenol converted to sulfonylchloride by known means and reacted with an amine, preferably an amine having at least two primary amino radicals. Sulfonamides of the monomeric alkylphenols while imparting detergency and dispersancy to lubricating oils prevent oxidative thickening of the oil.

    Abstract: Oil-soluble alkane hydroxy amine derivatives of alkenes containing at least ten carbon atoms, particularly low molecular weight unsaturated polymers of propene and butene, are useful as chemical intermediates and as additives in petroleum products. The amine derivatives are produced by nitrating the alkene with nitrogen tetraoxide under non-oxidizing conditions to form the corresponding nitro-nitrito alkane and reducing the nitro-nitrito alkane with hydrogen in the presence of a metallic hydrogenation catalyst.
