Iodine I2 - PubChem

Iodine is a naturally occurring element found in sea water and in certain rocks and sediments. There are non radioactive and radioactive forms of iodine. Iodine is used as a disinfectant for cleaning surfaces and storage containers and is used in skin soaps and bandages, and for purifying water. Iodine is also added to some table salt to ensure that all people in the United States have enough ...

Iodine Value (IV) The iodine value is a measure of the relative degree of unsaturation in oil components, as determined by the uptake of halogen. Because the melting point and oxidative stability are related to the degree of unsaturation, IV provides an estimation of these quality factors. The greater the iodine value, the more unsaturation and ...

Iodine Value. The iodine value (IV) is a measure of total unsaturation of a lipid material. The standard method EN 14111 in the European biodiesel standard is based on the classic wet chemical method (Wijs) for determining the IV. It purportedly serves a similar purpose in EN 14214 as do the restrictions on methyl linolenate and fish oil esters.

Iodine value chemistry Britannica

Iodine value, also called Iodine Number, in analytical chemistry, measure of the degree of unsaturation of an oil, fat, or wax; the amount of iodine, in grams, that is taken up by 100 grams of the oil, fat, or wax.Saturated oils, fats, and waxes take up no iodine; therefore their iodine value is zero; but unsaturated oils, fats, and waxes take up iodine.

Feb 20, 2021  Iodine value is used in analytical chemistry. Hydrogen and the halogen elements — fluorine, chlorine, bromine and iodine — resemble one another in that they are one electron short of a stable configuration and can form stable compounds by sharing an electron pair with another atom. In a carbon-hydrogen bond, the hydrogen’s single electron and one electron from the carbon are shared to ...
