ABSTRACT:
An improved process for the preparation of methylolaminotriazines etherified with alkanols and having per mol of the aminotriazine, an analytically determined average of 0.6 n to 2 n preferably 0.7 to 2 n methylol groups, which are etherified to the extent of 30 to 60%, n being the number of amino groups in the aminotriazine, wherein an aminotriazine is warmed to 80.degree. to 130.degree. C. with 0.7 n to 3 n mols of formaldehyde, 2 n to 10 n mols alkanol or a mixture of alkanols having 1 to 8 carbon atoms, the carbon chain of which, if having more than 2 carbon atoms, can also be interrupted by an oxygen atom, and 0 to 5 n mols of water, per mol of the aminotriazine, for 0.2 to 20 minutes, under elevated pressure, wherein the improvement comprises said aminotriazine being first heated to a temperature of 60.degree.-90.degree. C. in the presence of the formaldehyde and 0 to 30% by weight of the total amount of alkanol or alkanol mixture for 1 to 30 minutes at a pH 8 to 11 whereupon the remainder of the alkanol or alkanol mixture is added and the mixture is subsequently heated to 80.degree. to 130.degree. C. under elevated pressure in the presence of a strong inorganic or organic acid, at a pH of 3 to 8, for 0.2 to 20 minutes.
