Abstract:
In refining and petrochemical operations, even trace levels of conjugated dienes can cause gumming, catalyst deactivation, and product instability. Traditionally, the UOP 326 method measures Diene Value via a manual Diels–Alder reaction and titration—slow, labor-intensive, and requiring hazardous chemicals.
Da Vinci Laboratory Solutions introduces the fully automated Diene Value Analyzer, based on an Agilent HPLC with UV-Vis detection and a DVLS Reaction Module.
By automating the Diels–Alder reaction with a selective colorimetric reagent, it delivers accurate, repeatable DV results in just 5 minutes—boosting safety, speed, and sensitivity for process monitoring and quality control.
