Abstract: Reaction products of polyisobutenes having an average degree of polymerization P of from 10 to 100 and a content E of from 60 to 90% of double bonds which can react with maleic anhydride, E=100% corresponding to the theoretical value for the case where each molecule of the polyisobutene has such a reactive double bond, with oxides of nitrogen or mixtures of oxides of nitrogen and oxygen, are suitable as additives for fuels, in particular for gasoline engines, and for lubricants.

Abstract: Process for the preparation of 2,4,6-trimethylbenzoic acid, of the formula I, by reacting alpha -chloro-2,4,6-trimethylacetophenone with an alkali metal hydroxide solution and chlorine in the presence of a phase-transfer catalyst at temperatures from 0 to 150 DEG C and pressures from 0.01 to 50 bar, and a process for the preparation of the 2,4,6-trimethylbenzoic acid I, in which alpha -chloro-2,4,6-trimethylacetophenone, of the formula II, is prepared by reacting 1,3,5-trimethylbenzene with chloroacetyl chloride in the presence of a catalyst at temperatures from 0 to +150 DEG C and pressures from 0.01 to 50 bar, iron oxides being used as catalyst.
