Determination of the diene number (DV) using NIRS

Main document

This Application Note describes the determination of the diene number using an NIRS XDS RapidLiquid Analyzer in pyrolysis gasoline. The diene number is a measurement for the content of conjugated dienes in olefins. It is particularly important to detect them in petroleum products, as they influence the distillation and thus the quality of the final product. In contrast to the complicated and tedious wet-chemistry determination method, the NIRS method presented here is quick and convenient.
