    摘要： There is provided a process for purifying a fatty acid, which process comprises reacting a fatty acid with a lithium salt in a first solution and under conditions to allow formation of a precipitate of a lithium salt of the fatty acid; isolating the precipitate; dissolving the precipitate in a second solution followed by separation of the organic and aqueous layers so formed; and evaporating the organic layer to isolate the purified fatty acid. There is also provided a process for increasing the length of a fatty acid, and the use of a lithium salt to purify a fatty acid.

    摘要： The oligomerization of certain carboxylic acids and alkyl esters derived from natural oils is disclosed. This includes the oligomerization of C10-17 unsaturated carboxylic acids such as 9-decenoic acid, where the oligomerization yields a mixture of mono-, di- and tri-carboxylic acids. This also includes the oligomerization of certain alkyl esters, including the oligomerization of C10-17 unsaturated alkyl esters such as methyl 9-decenoate (9-DAME), where the oligomerization yields a mixture of mono-, di- and tri-carboxylic acid esters. Various end use applications for the oligomerized carboxylic acids and oligomerized alkyl esters are also disclosed.

    摘要： This invention proposes a lanolin substitute, capable of absorbing up to at least twice its weight of water or aqueous solution or aqueous suspension. It forms true emulsions, stable over time with a capacity for water absorption superior to that of lanolin.It also possesses the known emollient, moisturizing and occlusive properties of lanolin.This substitute is usable in all the present and future areas of application of lanolin: in the cosmetics industry, dermatology, and in industrial applications (polishes, lubricants . . . ).It is obtained by hemi-synthesis from a mixture of unsaturated fatty acids, esters of unsaturated fatty acids, unsaturated hydrocarbons or unsaturated derivatives of the latter and compounds comprising or generating hydroxyl functions, such as glycerol, preferably without a catalyst and in an atmosphere devoid of oxygen.Classical thermal treatment or preferably treatment by dielectric heating.

    摘要： Seeds, plants and oils are provided having high oleic acid; low linoleic acid; and low linoleic acid plus linolenic acid; and advantageous functional or nutritional properties. Plants are disclosed that contain a mutation in a delta-12 or delta-15 fatty acid desaturase gene. Preferred plants are rapeseed and sunflower plants. Plants carrying such mutant genes have altered fatty acid composition in seeds. In one embodiment, a plant contains a mutation in a region having the conserved motif His-Xaa-Xaa-Xaa-His, found in delta-12 and delta-15 fatty acid desaturases. A preferred motif has the sequence His-Glu-Cys-Gly-His. A preferred mutation in this motif has the amino acid sequence His-Lys-Cys-Gly-His. Nucleic acid fragments are disclosed that comprise a mutant delta-12 or delta-15 fatty acid desaturase gene sequence.
