Linear Alkylbenzene Isomer Distribution in Detergent Alkylate by GC
|Publication Date:||1 March 2006|
This method is for determining the isomer distribution in C15 through C20 mono-substituted linear alkylbenzenes (LABs). The 6-phenyltridecane and 7-phenyltridecane isomers are not resolved from each other and are determined as a composite. The lower limit of detection for a single component is 0.1 mass-%.
Components other than linear alkylbenzenes are not normally determined by this method; however, an estimate of the total LAB content of the sample may be obtained by measuring the components present in the sample other than the LABs.
