Abstract

By the oxidation of olefins having 16 to 70 C atoms by means of chromosulphuric acid in a single- or multi-stage process in at least one reactor having a narrow residence time spectrum, carboxylic acid mixtures can be produced. These can be processed with monoalcohols or polyols such as glycol, glycerol, trimethylolpropane, pentaerythritol or sorbitol to give esters and partial esters or to give mixtures of such esters. By reaction with basic oxides or metal hydroxides, the corresponding soaps of the carboxylic acids can be produced by direct reaction or by reprecipitation. By reaction with amines or aminoalcohols the amides, amido esters and amino esters are obtained. These products are distinguished by a pale colour, good heat stability and a wide application spectrum. <IMAGE>
