How it is made

Methylamines are prepared commercially by the exothermic reaction of methanol with ammonia over an amorphous silica-alumina catalyst at 350 - 450 °C. All three methylamines are produced. The reaction proceeds to thermodynamic equilibrium, the position of which is governed by the temperature and the nitrogen/ carbon (NH3/MeOH) ratio. ... In a typical commercial methylamine process ... methanol reacts with ammonia in the gas phase in one or more fixed-bed reactors.

The crude reaction mixture contains essentially excess ammonia, mono-, di-, and trimethylamines, reaction water, and unconverted methanol. Purification is generally effected in a train of four to five distillation columns.

Made by heating methyl alcohol, ammonium chloride, and zinc chloride to about 300 °C, by heating ammonium chloride and formaldehyde...

Interaction of methanol and ammonia over a catalyst at high temperature. The mono-, di-, and trimethylamines are all produced and yields are regulated by conditions. They are separated by azeotropic or extractive distillation.
