Production:

Menthol can be purified from natural peppermint crude oil or synthesized. The aerial part (stem; Branches; The essential oil obtained by steam distillation of leaves and inflorescences is called mint crude oil, and the oil yield is 0.5-0.6.

There are many ways to synthesize thin brain:

1, manufacturing from citronellal. Using the property that citronellal is easy to cyclize into isohumol, D-citronellal is cyclized into L-isohumol with an acid catalyst (such as silica gel), and the L-isohumol is separated and hydrogenated to produce L-menthol. Its stereo-structure can be partially converted into D-citronellal after thermal cracking, and it can be recycled.

2. Production from thymol In the presence of aluminum m-cresol, m-cresol is alkylated to produce thymol. All four stereoisomers of menthol (i.e. racemic menthol; Racemic neomenthol; Racemic isomenthol and racemic neoisomenthol). Distilling it, eliminating menthol fraction, repeatedly recrystallizing after making ester, and separating isomers and optical resolution.
