Process for preparing N-methyldialkylamines from secondary dialkylamines and formaldehyde

摘要

The present invention relates to a process for preparing N-methyldialkyl-amines by reacting secondary dialkylamines with formaldehyde at a temperature of from 100 to 200 C., by using from 1.5 to 3 mol of formaldehyde per mole of secondary dialkylamine and degassing the resulting reaction product, removing the aqueous phase and distilling the organic phase.
