OLIGO- OR POLYAMINES AS OXIDATION STABILIZERS FOR BIOFUEL OILS

摘要

Use of oligo- or polyamines having a number-average molecular weight of 4 6 to 70 000 which are free from phenolic hydroxyl groups for increasing the oxidation stability of biofuel oils which are based on esters of fatty acids , or of mixtures of such biofuel oils with medium distillates of fossil orig in and/or of plant and/or animal origin, which are essentially hydrocarbon m ixtures and are free of esters of fatty acids.
