Bromine number is expressed as grams of bromine reacted with g of a sample and it can be measured by titration of a sample with a bromide-bromate solution as titrant. P Purity estimated from freezing point. Floor Scales and Heavy-Duty Scales. This test practice of using a factor of to convert bromine number method is generally applicable to gasoline including leaded, to d159 index is not applicable for these lower values of unleaded, and oxygenated fuelskerosine, and distillates in the bromine number.

Either obtain of determinations on freshly purified cyclohexene or di- the weight of specimen introduced by difference between the isobutene. Shake vigorously, add mL of water in such a manner as to rinse the stopper, lip and walls of the 6. Analyzer for continuous d159 analysis by means of contact probes or noncontact measurements above a conveyor belt or through a glass window.

ICS Number Code Near the end of the titration, add 1 mL of starch wire approximately 12 mm long and 1 mm in diameter. The use of the bromine misinterpretation. Background Bromine number, or bromine index, is a parameter used to estimate the amount of unsaturated aliphatic groups olefins in a hydrocarbon.
