TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The diesel combination comprises a base diesel (balance) and additive (50-10000 ppm). The weight ratio of component B and component A is 0.01-10:1 (preferably 0.2-5:1). The alkenyl butanimide and/or alkenyl butanedioic acid amide are obtained by dehydrating polyolefin butanedioic acid and/or polyolefin succinic anhydride and amine at 40-250 degrees C for 1-10 hours. The polyolefin of polyolefin butanedioic acid and/or polyolefin succinic anhydride is polyisobutene, polypropylene, random or block polyethylene-allyl and polyisoprene having number-average molar mass of 300-5000 (preferably 500-2500). The amine is organic amine of formula H-N(R1)-R2 or H2N((CH2)xNH)yR6. The component B is phenylenediamine derivative antioxidant, 4-10C dialkyl p-phenylenediamine or bisphenol antioxidant connected via methylene or sulfur. The component B is N,N,N',N'-tetramethyl-p-phenylenediamine; N,N'-butanediol p-phenylenediamine; N,N'-dioctyl p-phenylenediamine; N,N'-di(1-methyl heptyl)p-phenylenediamine; 2,2'-methylene-di(4-methyl-6-tertiary butyl phenol); 4,4'-methylene-di(2-methyl-6-tertiary butyl phenol); 4,4'-methylene-di(2,6-tertiary butyl phenol); 4,4'-methylene-di(2-tertiary butyl phenol); 4,4'-thiodiglycol-(3-methyl-6-tertiary butyl phenol); 2,2'-thiodiglycol-(4-methyl-6-tertiary butyl phenol); 4,4'-thiodiglycol-(2-methyl-6-tertiary butyl phenol); 4,4'-thiodiglycol-(2, 6-tertiary butyl phenol); and/or di(3,5-tertiary butyl-4-hydroxybenzyl)sulfoether. The additive further comprises a metal deactivator. The weight ratio of component A and metal deactivator is 1:0.01-1. The metal deactivator is ammonium salt formed by triazole and alicyclic amine, or product obtained by subjecting triazole, formaldehyde and alicyclic amine, Schiff base and organic polycarboxylic acid to Mannich reaction. The base diesel comprises another diesel selected from petroleum diesel, Fischer-Tropsch process compound diesel, hydrocracking biodiesel and/or hydrogen containing diesel composition. The ratio of biodiesel to another diesel is 1:0-99.R6=H or 1-30C alkyl;R1-R2=1-30C alkyl or heteroatom containing 1-30C group;heteroatom=OH, COOH, NO2, NH2, ester group, acyl, alkoxy, halo or amino;x=2-4;andy=1-8.
