Petroleum Product Bromine Price and Bromine Index Tester MKC-710B

term
Bromine number
The grams of bromine consumed during the reaction with 100g of sample under specified conditions, expressed in grams per 100g.
Bromine index
The milligrams of bromine consumed when reacting with 100g of sample under specified conditions, expressed in mg/100g.

summary
Bromine value and bromine index measuring instruments are mainly used to determine the content of unsaturated hydrocarbons in petroleum products. When a sample containing unsaturated hydrocarbons is injected into a special electrolyte containing bromine, the double bonds of unsaturated hydrocarbons in the sample break and undergo addition reactions with bromine bonds. The bromine consumed in the reaction is replenished by electrolysis at the anode. By measuring the amount of electricity consumed by electrolyzing and supplementing bromine, the bromine index or bromine value of the sample can be calculated according to Faraday's law of electrolysis.
