How do you make dimethyl amines?
Dimethylamine is produced by catalytic reaction of methanol and ammonia at elevated temperatures and high pressure: 2 CH3OH + NH3 → (CH3)2NH + 2 H2O.
How is dimethyl amine produced?
Typically, dimethylamine is produced by carrying out the reaction between methanol and ammonia in the gaseous phase at a high temperature (approximately 400° C.) in the presence of a solid acid catalyst, such as alumina or silica alumina, capable of causing dehydration and amination.

Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
