ADDITIVE FOR IMPROVING THE OXIDATION-STABILITY AND/OR STORAGE-STABILITY OF LIQUID HYDROCARBON FUELS OR OXIDIZERS

摘要

The present invention relates to at least one modified alkylphenol-aldehyde resin as an additive for improving the oxidation stability and / or the storage stability of a motor fuel or a liquid hydrocarbon-containing fuel composition, aldehyde resin. The modified alkylphenol-aldehyde resin Having at least one alkylmonoamine group or an alkylpolyamine (alkylamine) group having 1 to 30 carbon atoms, preferably 4 to 30 carbon atoms, Can be obtained by a Mannich reaction of a hydrocarbon-containing compound and an alkylphenol-aldehyde condensation resin, The alkylphenol-aldehyde condensation resin At least one alkylphenol, preferably a monoalkylphenol, substituted with at least a linear alkyl group or a branched alkyl group having from 1 to 30 carbon atoms; And - at least one aldehyde having 1 to 8 carbon atoms, preferably 1 to 4 carbon atoms and / or one ketone;
