Menthol is an organic compound, specifically a monoterpenoid, that occurs naturally in the oils of several plants in the mint family, such as corn mint and peppermint. It is a white or clear waxy crystalline substance that is solid at room temperature and melts slightly above.
Mentha canadensis is rich in natural menthol compared to other mint species, and menthol is used extensively in a number of pharmaceutical preparations. Approximately 4000 tons of Japanese mint oil and 2000 tons of menthol were produced in the world in 1998. The major producing countries are Brazil, Paraguay, Taiwan, Japan, China, India, and ...

Methanol fuel is an alternative biofuel for internal combustion and other engines, either in combination with gasoline or independently. Methanol (CH 3 OH) is less expensive to sustainably produce than ethanol fuel, although it is more toxic than ethanol and has a lower energy density than gasoline.
Syngas is produced from biomass gasification and further converted into green methanol. [62] Another method of producing green methanol involves combining hydrogen, carbon dioxide, and a catalyst under high heat and pressure. [61] To be classified as green methanol, the hydrogen must be green hydrogen, which is produced using renewable ...

Methanol can also be produced at atmospheric pressure from CO 2 by catalytic hydrogenation of CO 2 with H 2 [22] where the hydrogen has been obtained from water electrolysis. This is the process used by Carbon Recycling International of Iceland. Methanol may also be produced through CO 2 electrochemical reduction, if electrical power is ...
