Automatic Bromine Index Tester 0.1mgBr Detection ASTM D1492

SH0630 Automatic Bromine Valence Bromine Index Tester

The SH0630 automatic bromine valence bromine index analyzer adopts the principle of microcoulometry titration (electric method). The sample is injected into the titration cell, and the unsaturated hydrocarbons of the sample undergo an addition reaction with bromine in the electrolyte. By calculating the amount of electricity consumed by generating bromine, the bromine valence and bromine index of the sample can be calculated according to Faraday's law of electrolysis. The electrolytic cell adopts a specially made ceramic sand core instead of the previous ion exchange membrane, which is more convenient to maintain, improves measurement sensitivity, and results are more stable, accurate, and reproducible.

Scope of application: The instrument is suitable for the determination of bromine value and bromine index of petroleum and chemical products such as gasoline, kerosene, diesel, lubricating oil, and light and heavy aromatic hydrocarbons.

Bromine value, also known as bromine value, is an indicator of the content of unsaturated hydrocarbons in organic matter. The grams of elemental bromine consumed in a 100 gram sample are called bromine valence, while the milligrams of bromine consumed in a 100 gram sample are called bromine index. The higher the bromine value or bromine index, the higher the content of unsaturated hydrocarbons in the sample, that is, the higher the degree of unsaturation. In oil production, this value is an important indicator for measuring the stability of oil products. In some chemical production processes (such as long-chain alkylation reactions), it can also be used to roughly estimate the conversion rate of the product
