Unsaturation testing before and after oil hydrogenation
Thread Content
In oils, the bromine value is generally used as an indicator of unsaturation, and oil hydrogenation can convert the unsaturated hydrocarbons in oils into saturated hydrocarbons. The current challenge in the experiments is that the crude oil used before hydrogenation contains a high level of wax, which causes it to solidify at room temperature; as a result, it is difficult to use conventional bromine value titration/microcoulomb methods to determine the bromine value. Are there any other methods to determine the unsaturation of this type of crude oil?

Adjust the composition of the electrolyte by adding components that can dissolve paraffin, in such a proportion that the paraffin in the sample is dissolved. Refined white oil or refined aviation kerosene can generally be used. A small amount of xylene can also be added. The addition of these solvents causes slight stratification with the electrolyte, but it does not affect sample measurement. It is also possible to use the fluorescent indicator method for analyzing the hydrocarbon composition of oils.
