ABSTRACT:
A method to quantify the conjugated dienes in a feedstream including the steps of dissolving 4-methyl-1,2,4-trazoline-3,5-dione (MTAD) in said feedstream, and determining the molar concentration of said conjugated dienes and/or the carbon number distribution of said conjugated dienes by GC/MS and GC/NCD (Nitrogen Chemiluminescence Detection).
