| titleOfInvention | Process for the preparation of ethers of methylolated melamines |
| abstract | The process for the preparation of methylol aminotriazines etherified with alkanols with an analytical mean of 0.6n to 2n, preferably 0.7n to 2n methylol groups per mole of aminotriazine, which are etherified to 30 to 60%, where n is the number of Amino groups of aminotriazine in which an aminotriazine, preferably melamine, with 0.7n to 3n, preferably 0.77n to 3n mol of formaldehyde, 2n to 10n, preferably 2.5n to 7n, mol of an alkanol or a mixture of alkanols with 1 to 8 carbon atoms, the carbon chain, if it has more than 2 carbon atoms, can also be interrupted by an oxygen atom and 0 to 5n, preferably 0 to 3n, moles of water per mole of the aminotriazine under increased pressure to 80 for 0.2 to 20 minutes is heated to 130 ° C, characterized in that first the aminotriazine with the formaldehyde with 0 to 30% by weight of the alkanol or alkanol mixture intended for use for 1 to 30 minutes, preferably 10 to 20 minutes, at pH values from 8 to 11, preferably 9 to 10.5, heated to temperatures from 60 to 90 ° C., preferably from 70 to 80 ° C., then with the rest of the alkanol or alkanol mixture intended for use added and then at a pH between 3 and 8, preferably 3 and 7, during 0.2 to 20 minutes under elevated pressure to 80 to 130 ° C. |
