In chemistry, the iodine value (IV; also iodine absorption 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 .
Biodiesel production is the process of producing the biofuel, biodiesel, through the chemical reactions of transesterification and esterification. [1] This process renders a product (chemistry) and by-products. The fats and oils react with short-chain alcohols (typically methanol or ethanol). The alcohols used should be of low molecular weight.
Bromine number – Mass of bromine absorbed by 100 grams of a given substance; EN 14214 – Fuel standard for biodiesel; Epoxy value – Measure of the epoxy content of a substance; Hydroxyl value – Mass of KOH needed to neutralize 1 gram of acetylized substance; Iodine value – Mass of iodine absorbed by 100 grams of a given substance
One common measure of the "siccative" (drying) property of oils is iodine number, which is an indicator of the number of double bonds in the oil. Oils with an iodine number greater than 130 are considered drying, those with an iodine number of 115–130 are semi-drying, and those with an iodine number of less than 115 are non-drying.
Waste vegetable oil that has been filtered. Vegetable oil can be used as an alternative fuel in diesel engines and in heating oil burners. When vegetable oil is used directly as a fuel, in either modified or unmodified equipment, it is referred to as straight vegetable oil (SVO) or pure plant oil (PPO).
129 I is one of the seven long-lived fission products that are produced in significant amounts. Its yield is 0.706% per fission of 235 U. [7] Larger proportions of other iodine isotopes such as 131 I are produced, but because these all have short half-lives, iodine in cooled spent nuclear fuel consists of about 5/6 129 I and 1/6 the only stable iodine isotope, 127 I.
Biodiesel currently has 3% of the diesel market in Germany and is the number 1 alternative fuel. [17] The German government has a Biofuels Roadmap in which they expect to reach 10% biofuels by 2010 with the diesel 10% coming from fuel made from vegetable oil. [18] From 2005 to 2007 a number of types of vegetable oil have doubled in price.
