    Abstract: The use of polycyclic phenolic compounds which have up to 20 benzene rings per molecule and are obtainable by reacting a tetrahydrobenzoxazine I where R1 is a hydrocarbyl radical and R2, R3, R4 and R5 are each independently hydrogen atoms, hydroxyl groups or hydrocarbyl radicals with one or more of the same or different phenols II where R7, R8, R9 and R10 are each independently hydrogen atoms, hydroxyl groups or hydrocarbyl radicals, and/or with one or more of the same or different tetrahydrobenzoxazines I, with the proviso that at least one of the substituents has from 13 to 3000 carbon atoms and the remaining substituents, when they are hydrocarbyl radicals, have in each case from 1 to 20 carbon atoms as stabilizers for stabilizing inanimate organic material against the action of light, oxygen and heat.

    Abstract: Disclosed are polyisobutene amines of general formula R1CH2-NR2R3 in which R1 represents a polyisobutyl radical that is derived from isobutene and up to 20 percent by weight of n-butene and has a number average molecular weight Mn ranging from 600 to 770, and R2 and R3 independently represent hydrogen, a C1-C18 alkyl radical, C2-C18 alkenyl radical, C4-C18 cycloalkyl radical, C1-C18 alkyl aryl radical, hydroxy-C1-C18 alkyl radical, poly(oxyalkyl) radical, polyalkylene polyamine radical, or polyalkylene imine radical, or a heterocyclic ring along with the nitrogen atom to which they are bonded. Said polyisobutene amines are suitable as detergents in gasolines, reduce valve stickiness, and improve compatibility of the detergents with flotation oils and compatibility in fuel compositions containing a mineral fuel percentage and C1-C4 alkanols.

    Abstract: A synergistic mixture comprising from 1 to 99.9% by weight of compounds having structural elements (I) in which the free valencies on the oxygen atom and on the nitrogen atom may be combined to form a five-, six- or seven-membered ring and the benzene ring may also bear substituents at one or more of the free positions, and from 0.1 to 99% by weight of sulfur-containing organic compounds with antioxidant action. This synergistic mixture is suitable as a stabilizer for stabilizing inanimate organic material, especially mineral oil products and fuels, against the action of light, oxygen and heat.
