Skin-conditioning succinic acid derivatives

Process for the production of fatty ketones

Process for the production of branched fatty acids and esters thereof

The use of fatty oil ex Helianthus annuus containing 78 to 92% by weight oleic acid and 2 to 10% by weight linoleic acid for the production of alkali metal, ammonium and/or alkanolammonium salts of optionally dihydroxy-substituted fatty acids as emulsifiers for emulsion polymerization. Excellent polymerization results are obtained despite the high linoleic acid content.

The use of a fatty oil ex Helianthus annuus containing 78 to 92% by weight oleic acid and 2 to 10% by weight linoleic acid for the production of diperazelaic acid, with elimination of enrichment steps with respect to the oleic acid content, by fat splitting, distillation, oxidative ozonolysis of the fatty acid mixture obtained, and reaction of the azelaic acid thus obtained with hydrogen peroxide to form diperazelaic acid. The resulting diperazelaic acid has improved stability in storage and is obtained in high yields and in highly pure form.

Bicyclic decanedioic acids corresponding to the following general formula ##STR1## in which R represents a C.sub.1 -C.sub.22 alkyl radical, a C.sub.2 -C.sub.34 alkylcarbonyl radical, or a residue of a polyalkoxylated C.sub.2 -C.sub.22 fatty alcohol, represent a new class of dicarboxylic acids which are useful as flotation aids in the flotation of non-sulfidic ores.

Derivatives of tricyclo-[5.2.1.0.sup.2,6 ]-dec-3-ene corresponding to the following general formula ##STR1## in which R.sup.1 is hydrogen; a linear or branched C.sub.1 -C.sub.8 alkyl radical; an acyl radical R.sup.2 -CO, where R.sup.2 is hydrogen or a linear or branched C.sub.1 -C.sub.18 alkyl or alkenyl radical; or a hydroxyalkyl radical ##STR2## in which R.sup.3 and R.sup.4 independently of one another may be hydrogen or a hydroxy group and m and n are integers of 0 to 5 and the sum (m+n) is an integer of 1 to 5, with the proviso that at least one of the radicals R.sup.3 and R.sup.4 is a hydroxy group; are used as frothers in the flotation of coal and ores.
