Absolute neutral oil content of vegetable oils by radiochemical technique
Journal of the American Oil Chemists' Society, 1968AbstractLaboratory refining loss, determined by the chromatographic method, is checked by a radio‐chemical procedure. Neutral triglycerides are labeled with C14‐tripalmitate and passed through an alumina column to find out if the alumina retains a percentage of them.Cottonseed oil is also labeled and, by applying the calculations of the isotope ...

Fatty Acid Content of Selected Seed Oils
Journal of Herbal Pharmacotherapy, 2002Fatty acid content of selected seed oils from world-wide edible fruits, Ceratonia ciliqua (carob) from Caesalpiniaceae family, Diospyros kaki (persimmon) from Ebenaceae family, Zizyphus jujuba (jujube) from Rhamnaceae family, and Persea gratissima (avocado pear) from Lauraceae family, were determined by capillary gas chromatography- mass spectrometry ...

Sulfur content of rapessed oils
Journal of the American Oil Chemists' Society, 1976AbstractSulfur contents in rapeseed oils were determined by reduction with Raney nickel, acidification, and titration of released H2S with mercuric acetate. The sulfur contents decreased with successive steps of industrial processing, i.e., crude oil, 17–31 ppm S; degummed, 16 ppm; alkali refined, 4–9 ppm; bleached, 3–5 ppm; and deodorized, <1 ppm ...

Approaches to the Determination of Oil Content in Oil Shale
Advanced Materials Research, 2011Oil and gas are important energy minerals and strategic resources. Moreover, as their substitute, oil shale is the non-renewable fossil fuel resource. In this paper, regarding the oil shale of Huadian in Jilin Province as raw material, we made a research on the approaches to extracting shale oil from oil shale as well as an experimental determination ...

Determination of the oil content of waxy oils
Recueil des Travaux Chimiques des Pays-Bas, 1948AbstractA new method is described to determine the oil content of waxy oils. The oil content is determined as a function of the pour point of the dewaxed oil. The waxy oil is dissolved in a mixture of butanone and toluene of a suitable composition, after which part of the wax is precipitated by cooling the solution down to certain temperatures and ...

LINOLEIC ACID CONTENT OF FATS AND OILS
Journal of the American Medical Association, 1960IT IS accepted generally that specific alteration in the diet will lower the concentration of cholesterol in the blood. The most effective results to date have been achieved by increasing consumption of polyunsaturated fatty acids, particularly linoleic acid.

Oil and Water Content of Oil Sands, Grozny, Russia
AAPG Bulletin, 1929ABSTRACT The writers conclude from their laboratory study of the displacement of oil by water, in sands of different size of grain, that it is very important to consider the relatively large amount of water retained in the reservoir sand after ordinary production of the wells ceases.

Canadian Journal of Plant Science, 1982
Thirty-five sunflower (Helianthus annuus L.) hybrids and seven parental lines were analyzed for hull and oil content. The hull content varied from 21.6 to 28.2% in the hybrids. The oil content varied from 59.8 to 64.6% in the kernel and from 42.5 to 50.3% in the whole seed. The variation of these characters was even greater in the parental lines. Hull

Determination of the Oil Content of Soils
1985The precision and accuracy of acidification followed by Soxhlet extraction with trichlorotrifluoroethane to estimate the oil and grease content of oil-contaminated soils was determined. The amounts of oil and grease were determined gravimetrically after solvent extraction. Stock oil-soil mixtures prepared with vegetable oil, No. 2 fuel oil, No.
