Rapeseed oil fatty acids

Using similar reaction conditions with rapeseed oil, fatty acids were treated with various supercritical alcohols. From the HPLC analysis, it was shown that selective reactions could be obtained. Figure 5 presents the yields of alkyl esters of five fatty acids treated in various supercritical alcohols at 300°C. In the case of methanol, the reaction time for the complete conversion...

Methyl esters of soya, rapeseed and palm oil fatty acids used as biodiesel (Chapters 7 and 8) are preferentially manufactured by transesterification." The acid catalyzed esterification and the alcoholysis of triacylglycerides apply also for the manufacture of higher alcohol monoesters as well as for fatty acid polyol esters. Due to their oily consistency and to their solubilizing properties fatty acid esters of low Mw alcohols are components in odorous substances like perfumes, and cosmetic and drug formulations such as ointments, creams or lotions. 

The magnitude of the variation in the composition of rapeseed oil and meal now commercially available has created a need for new terms to describe the products derived from rapeseed. The fatty acid composition of most edible vegetable oils such as soybean, sunflower, or cottonseed oils, varies within narrow limits. Thus, the species or commodity name (e.g., soybean oil) provides a reasonable description of the fatty add composition of soybean oil. In contrast, the erucic acid content of commercially available rapeseed oil may vary from near zero to 55%, and the oleic acid from 10 to more than 60%. A number of terms have been proposed or utilized to describe the new rapeseed oil whose fatty acid composition has been altered by the elimination of erucic acid these include low erucic acid rape-seed oil (LEAR), canbra, and canola. Similar terms such as high erucic acid rapeseed oil (HEAR) and common or traditional rapeseed oil have been used to describe rapeseed oil whose fatty acid composition includes substantial amounts of erucic acid. 

To promote uses of rapeseed ( Brassica. nopus) oil, some new oil fatty acid profiles are needed. In this paper, we report the development of low linolenic acid (Cl8 3) iines. The triacylglycerol (TAG) lipid structure of high and low Cl8 3 rapeseed oils has been determined to test Sn-2 specific acyltransferase activities. No differences were detected among the lines for the TAG lipid structure even with a 0.9% Cl8 3 content. 

The reaction is also broadly used in industrial oleo-chemistry for h. of unsaturated - fatty acids. Starting materials are predominantly acid oils from the refining of oils for nutrition ( foots ), split (- hydrolysis) fatty acids, e. g., from tallow and the stearin fraction from the olein/stearin separation (- crystallization). H. is also applied for making - hydroxys-tearic acid from castor oil fatty acid, to eliminate unsaturation in coconut oil prior to - fractionation, to get - arachidic and - behenic acid from - fish and - rapeseed oil, to improve color in - dimer acid and to eliminate unsaturation in the starting material prior to separation by - crystallization of- stearic from - isostearic acid. 

Fats and oils may be synthesized in enantiomerically pure forms in the laboratory (30) or derived from vegetable sources (mainly from nuts, beans, and seeds), animal depot fats, fish, or marine mammals. Oils obtained from other sources differ markedly in their fatty acid distribution. Table 2 shows compositions for a wide variety of oils. One variation in composition is the chain length of the fatty acid. Butterfat, for example, has a fairly high concentration of short- and medium-chain saturated fatty acids. Oils derived from cuphea are also a rich source of capric acid which is considered to be medium in chain length (32). Palm kernel and coconut oils are known as lauric oils because of their high content of C-12 saturated fatty acid (lauric acid). Rapeseed oil, on the other hand, has a fairly high concentration of long-chain (C-20 and C-22) fatty acids. 

The primary products used are fatty acids with 12—18 carboa atoms and fatty alcohols, or esters of fatty acids such as the glycerides of rapeseed and lard oil (18). Eatty acid amines and amides are used ia metal working, particularly ia emulsions (18).
