Дистиллированная жирная кислота сои , Soya Fatty Acid: Soybean oil fractions were obtained by collecting the extract at different time intervals during supercritical carbon Dioxide extraction. The extraction was performed at the following temperatures : 313 323 and 333k and at pressures Of 300 400 and 500 bar. The triacylglycerol composition and concentration of fatty acids in soybean oil fraction was Evaluated. The fatty acid and triacylglycerol compositions of soybean oil obtained with supercritical carbon dioxide Was compared with the soybean oil extracted with n-hexane. The extraction temperature and pressure did not influence The fatty acids composition which however differed in different fractions collected at different time intervals The concentrations of my ristic palmitic linoleic and linolenic fatty acids of soybean oil were the highest in the first Fraction and then decreased while the concentrations of stearic and oleic acids showed the opposite trend the solubility Of all fatty acids increased with the pressure from 300 to 400 bar at constant temperature while in the interval From 400 to 500 bar the solubility decreased with long chain fatty acids (c20-c24)
Obtained by splitting and the subsequent vacuum distillation of soybean oil. The product obtained has a melting point above 25 º C. Solid yellow or clear fluid at room temperature. Rich in linoleic acid and less in oleic acid. Soya Fatty acids are used among others applications: Amines, betaines, esters, fatty alcohols, lubricants, surface finishes, detergents, cosmetics and personal care, and solid liquid soaps, textile finishing, leather finishing, finishing fibers, coatings, resins, and surfactants.
Distilled Soya Fatty Acid is obtained by splitting and the subsequent vacuum distillation of soybean oil. The product obtained has a melting point above 250 C. It appears as Solid yellow or clear fluid at room temperature.
Distilled Fatty Acids are used in manufacturing of different industrial products such as alkyd resins for paints, textile auxiliaries, greases, rubber chemicals, fatty acid esters, fatty amines, detergents, cosmetics personal care products, solid liquid soaps, textile finishing, leather finishing, finishing fibers, surfactants and etc.
