Bromine value
Bromine is a chemical element with the symbol Br and atomic number 35. It is a volatile red-brown liquid at room temperature that evaporates readily to form a similarly coloured vapour. Its properties are intermediate between those of chlorine and iodine. Isolated independently by two chemists, Carl Jacob Löwig (in 1825) and Antoine Jérôme Balard (in 1826), its name was derived from the Anci… In chemistry, the bromine number is the amount of bromine (Br2) in grams absorbed by 100 grams (3.5 oz) of a sample. The number indicates the degree of unsaturation. The bromine number is useful as a measure of aliphatic unsaturation in gasoline samples. The California ARB, in its Motor Vehicle Fuels Compliance Assistance Program, indicated that every unit of bromine number is equivalent to twice the percentage point of olefin content in gasoline.
