Iodine value of vegetable oils

Web7 apr. 2024 · Methacrylated vegetable oils are promising bio-based polymerizable precursors for potential material application in several fields, such as coating technologies or 3D printing. The reactants’ availability for their production is an enormous advantage, but the modified oils also exhibit high apparent viscosity values and poor mechanical properties. WebIn the pharmacopoeia, two different types of Hydrogenated vegetable oils are defined on the basis of their melting point and iodine value: Type I Hydrogenated vegetable oils have a higher melting point and lower iodine value, and occur in various forms, e.g. fine powder, flakes, or pellets.

DETERMINATION OF THE IODINE VALUE OF OILS AND FATS …

In chemistry, the iodine value (IV; also iodine adsorption value, iodine number or iodine index) is the mass of iodine in grams that is consumed by 100 grams of a chemical substance. Iodine numbers are often used to determine the degree of unsaturation in fats, oils and waxes. In fatty acids, unsaturation occurs mainly as double bonds which are very reactive towards halogens, the iodine in this case. Thus, the higher the iodine value, the more unsaturations are present in the fat. It c… WebIntroduction. Iodine value is additionally called Iodine number, in analytical chemistry, the measure of the degree of unsaturation of fat, oil, and wax. The quantity of iodine, in grams, that’s taken up by 100 grams of the oil, fat, or wax.
