The KR-BN630 automatic bromine number tester adopts the principle of microcoulometric titration (coulometric method). The sample is injected into the titration cell, and the unsaturated hydrocarbon of the sample undergoes an addition reaction with the bromine in the electrolyte. The bromine value and the bromine index of the sample can be calculated according to the Faraday's law of electrolysis by calculating the amount of electricity consumed for bromine generation. The electrolytic cell uses a special ceramic sand core instead of the previous ion exchange membrane, which is more convenient for maintenance, improved measurement sensitivity, and more stable, accurate and repeatable results.
Bromine value (or bromine value) is an index to measure the content of unsaturated hydrocarbons in organic matter. The number of grams of elemental bromine consumed by a 100-gram sample is called the bromine value, and the number of milligrams of bromine consumed by a 100-gram sample is called the bromine index. The higher the bromine value or the bromine index, the higher the content of unsaturated hydrocarbons in the sample, that is, the higher the degree of unsaturation. In the production of oil products, this value is used as an important indicator to measure the stability of oil products. In some chemical production (such as long-chain alkylation reactions), it can also be used to roughly estimate the conversion rate of the product. Scope of application: The instrument is suitable for the determination of bromine value and bromine index of petrochemical products such as gasoline, kerosene, diesel, lubricating oil, light and heavy aromatic hydrocarbons.
