Abstract
1360134 Tris-(dimethylamino)methane F HOFFMANN-LA ROCHE & CO AG 24 March 1972 [26 March 1971] 13879/72 Heading C2C Tris-(dimethylamino)methane is made by reacting a dimethylformamide dialkyl acetal, where the alkyl groups contain 1-4 carbon atoms, with an excess of dimethylamine, in the presence of an acidic catalyst which is not deactivated under the conditions employed, e.g. a sterically hindered phenol.
