<p>A process for the preparation of products, which may be technically valuable, from mineral oil distillates or from solvent extracts of such distillates is disclosed, which process comprises oxidizing one or more mineral oil distillates and/or solvent extracts of mineral oil distillates having a content of aromatically bound carbon corresponding to a VGCvalue of at least 0.85, preferably at least 0.90, and an average molecular weight of 150 to 600, preferably 200 to 500, by blowing oxygen, preferably in the form of air, thereinto and fractionating the oxidized distillate and/or extract, at least one product fraction having a boiling point interval in the temperature range of from about 320.degree.C to about 420.degree.C at 760 mm Hg and another product fraction having a lowest boiling temperature of 400.degree.C or above at 760 mm Hg being isolated in the fractionation and products obtained by this process.</p> |
