Abstract: The proposal is for unsaturated fatty substances with improved cold behavior obtained by (a) transesterifying a new low stearic (LS) sunflower oil with an oleic acid content of over 85 wt. % and a stearic acid content of under 3 wt. %, and (b) hydrogenating the resultant methyl esters in the prior art manner into the corresponding unsaturated fatty alcohols in the iodine number range from 90 to 100. The fatty substances are also distinguished by improved color and odor and are suitable for making fatty chemical products, e.g. alkoxylates, ether sulphates, sulphates and esters.

Abstract: The invention pertains to synthetic esters containing a) fatty acid mixtures with an oleic acid content of 85 wt % and a stearic acid content of 0.5 to 2.5 wt %, both relative to the mixture, b) alcohols and c) as desired, polyfunctional carboxylic acids. The invention also relates to hydraulic oils based on these esters, and to the use of the esters as lubricants, as hydraulic oils and in cosmetics.

Abstract: A process for producing unsaturated fatty compounds having improved low-temperature properties bya) splitting lauric oils into fatty acids and glycerol,b) subjecting the fatty acids to fractional crystallization to obtain a fraction of unsaturated fatty acids, andc) hydrogenating the unsaturated fatty acids, optionally after converting the unsaturated fatty acids into their lower alkyl esters, to form unsaturated fatty alcohols having an iodine value of from about 85 to about 100.

Abstract: Described is the use of oleophilic monomeric and/or oligomeric diesters of carbonic acid with the same or different oil-soluble and ecologically compatible mono-functional and optionally polyfunctional alcohols as a component of oil-based or water-based drilling fluids and other fluid drill-hole treatment agents. The invention in one embodiment comprises oil-based fluids, and particularly inverted fluids of the W/O type, which in the continuous phase at least in part contain oleophilic carbonic acid diesters. In a further important embodiment the invention relates to water-based emulsion fluids which in the dispersed oil phase at least in part contain said oleophilic carbonic acid diesters.

Abstract: Methods of use of carbonic acid esters corresponding to general formula I: ##STR1## in which R.sup.1 is an alkyl radical derived from an aliphatic saturated primary alcohol containing 1 to 22 carbon atoms and R.sup.2 is an alkyl radical derived from an aliphatic, saturated primary alcohol containing 1 to 8 carbon atoms and/or has the same meaning as R.sup.1 and n is a number of 2 to 20 while m is 0 or has the same meaning as n, as foam control agents for the sugar beet or potato-processing food industry and/or in fermentation processes are provided. In the industrial processing of sugar-containing plant juices, as carried out on an industrial scale in the case of sugar beet, particular difficulties are caused by excessive foaming in the defecation units, during transport of the beet, in the diffusors and in the carbonizing tanks and before the evaporators, thus, use of the esters in these processes is advantageous.
