Accordingly, the more polar the solvent the less oleic acid you will be able to dissolve in it. To evaluate the selectivity of supercritical carbon dioxide (scCO 2) as a solvent to deacidify vegetable oils, the solubility of oleic acid and of a mixture of oleic acid and refined sunflower oil in scCO 2 was measured. In chemical terms, oleic acid is classified as a monounsaturated omega-9 fatty acid, abbreviated with a lipid number of 18:1 cis-9.It has the formula CH 3 (CH 2) 7 CH=CH(CH 2) 7 COOH. Stearic acid is significantly less soluble in methanol compared to ethanol. Names.

As a general rule, polar substances are soluble in polar liquids, while non. As a result, when a drop of an oleic acid solution is placed on the surface of water, the oleic acid molecules form a thin layer as alcohol evaporates. Based on the solubility determinations and emulsification properties oleic acid and surfactants cremophor RH 40 and PEG 400 were selected for further study. The reason is simple - it is most soluble in non-polar solvents due to the presence of the long (C18) carbon chain. such as the fatty alcohol oxidase . veried that the solubility of ethanol in the oil phase increased. 0.895 g/mL.

Oleic Acid Methanol Oleic Acids Fatty Acids Sterol O-Acyltransferase Esters Cholesterol Esters Stearic Acids Cholesterol Phosphatidylcholine-Sterol O-Acyltransferase Palmitic Acids Acyltransferases Retinol O-Fatty-Acyltransferase Triglycerides Palmitic Acid Linoleic Acid Linoleic Acids Phospholipids Fatty Acids, Unsaturated Plant Oils Lipids Protein O-Methyltransferase . Not for drug, household or other uses. Oleic acid is a fatty acid that occurs naturally in various animal and vegetable fats and oils.It is an odorless, colorless oil, although commercial samples may be yellowish. Oleic acid is used as an emulsifying agent for facial creams and lotions, as an accelerator in rubber industry, as an emollient, as a solubilizing agent in aerosol products and as a soldering flux in stained glass work for joining lead came. Solubility insoluble in water, unlimited solubility in alcohol, ether, acetone and benzene Stability decomposes at 80-100C with the forma-tion of irritating vapour Production hydrolytic cleavage of animal fats and plant oils PubChem . A considerable series of pure fatty acids has been prepared and their solubilities have been determined at temperatures down to 70 in acetone, methanol and Skellysolve B.
