Synthesis route :
Thymol is synthesized by an ortho-alkylation process of meta-Cresol with propylene, in the presence of aluminum oxide. This synthesis must be carried out at high pressure and temperature. The reaction is not total, the rest of the reagents are separated from the mixture by a fractional distillation at the end of the reaction.
Synthesis precursor :
Thymol is a precursor to L-Menthol synthesis by catalytic hydrogenation under high temperature and pressure.
Isomerism :
Ortho-Thymol, also called Carvacrol, has to be distinguished from para-Thymol, also called para-Cymen-5-ol. Both are Thymol isomers and do not share the same smell.
L-Carvone and Dimethyl Benzyl Carbinol are some of the constitutional isomers of Thymol. Their smell is however very different, as it is more minty or floral-fresh.
