TLC of stearic acid, stearyl alcohol, and methyl stearate on silica gel (prewashed with methanol) with methanol - chloroform 1:1 followed by drying for 24 h at room temperature. Six new derivatization reagents were evaluated: gentian violet, methylene violet, methylene blue, methyl green, malachite green, and Janus blue. Detection by dipping for 5 s, followed by drying for 24 h at room temperature. Quantitative determination by absorbance measurement. The results obtained indicate that all of the new derivatization reagents give better results than the universally applied Rhodamine B. The best reagents for quantitative determination of stearic acid are methylene blue and Janus blue, for stearyl alcohol malachite green and Janus blue, and for methyl stearate methylene blue, Janus blue, and malachite green.
