Exact value and correlation of diolefin value to that of Existent Gum and Potential Gum specifications are not available in scientific literature. Typical Diolefins values (Maleic Anhydride Value ) of FCC Light Naphtha will be greater than 0.5 % and that of FCC Heavy Naphtha will less than 0.5 % Analysis of Diolefins is done by UOP326 - 08 Diene Value by Maleic Anhydride Addition Reaction .
