J. Chromatogr. A 1218 (19), 2785-2792 (2011). Examination of the applicability of TLC for the analysis of biodiesel conversion. Biodiesel is a complex mixture which complicates the analytical separation and requires a large set of data for understanding reaction kinetics. A flame ionization detector (FID) and a modified TLC staining procedure were evaluated in comparison with the well-established but time-consuming and expensive GC and HPLC methods. The TLC staining method is suited for quantitative analysis due to no background. Demonstration by using several experimental samples produced by enzymatic conversion of rapeseed oil to biodiesel. It was found that the first reaction step (6 h) resulted in 85–95 % conversion and the second step (after removal of glycerol and water) increased the yield to 97–98 %. All components of the mixtures were separated and quantified. Relation of the biodiesel contents measured by TLC and GC gave the values of 1.03 ± 0.07 (TLC-staining) and 0.95 ± 0.04 (TLC–FID), which indicated the applicability of the TLC methods.
