Standard material for bromine value determination
Standard substances for bromine value determination are primarily used for measuring the unsaturation of petrochemical products, among other applications.
Standard substances for bromine value determination are primarily used for measuring the unsaturation of petrochemical products, among other applications. These are typically national second-class standard substances produced by the Petrochemical Research Institute, available in various concentration specifications, and suitable for bromine value determination experiments such as coulometric titration and potentiometric titration. Specific details are as follows:
Concentration specifications: Common concentrations include 1.14 gBr/100 g, 5.02 gBr/100 g, 11.4 gBr/100 g, 49 gBr/100 g, and 98.3 gBr/100 g, among others, and can be selected based on specific testing requirements.
Standard number: A series of bromine value standard samples provided by the Petrochemical Research Institute, with standard numbers GBW (E) 060114-GBW (E) 060121.
Function: By measuring the standard substances, necessary control conditions such as the addition rate, droplet volume, and titration endpoint potential for bromine value determination can be obtained, which helps improve the accuracy and precision of the analysis. They can also be used for regular verification and confirmation of the accuracy and reliability of instruments and equipment to ensure the accuracy and comparability of bromine value determination results.
Related standards: According to SH/T0630-1996 “Determination of Bromine Value and Bromine Index of Petroleum Products (Electrolytic Method),” bromine value standard substances can be used to determine the bromine value of petroleum products such as gasoline, kerosene, diesel fuel, lubricating oil, wax oil, and light and heavy aromatics. The measurement range is 0.1-300 gBr/100g.
