The present invention relates to a method for modifying a triazine compound
comprising the steps of
a) Providing at least one triazine compound of the general formulae (I)
wherein
- R1 and R2 mean independently from each other Q1 or a moiety of the formula R3-N-R4 or R5-N-R6 bound with its central nitrogen atom to the triazine ring of the structure of formula (I), whereat
- Q1 means H, hydroxyl, a linear or branched C1-C30-alkyl or a cyclic substituent in form of a C5-C20-cycloalkyl, a C5-C20-aryl, a C1-C20-alkylsubstituted C5-C20-aryl, wherein in each case one or multiple carbon atoms can be substituted by one or multiple oxygen atoms, sulphur atoms, substituted nitrogen atoms and/or by one or multiple groups of the type -C(O)O-,-OC(O)-,-C(O)- and/or -OC(O)O-, and/or can be functionalized by one or multiple hydroxyl groups and/or mercapto groups,
- R3, R4, R5 and R6 mean independently from each other H, linear or branched C1-C20-alkyl, C5-C20-cyclo alkyl, C5-C20-aryl, C1-C20-alkylsubstituted C5-C20-aryl, wherein in each case one or multiple carbon atoms can be substituted by one or multiple oxygen atoms, sulphur atoms and/or substituted nitrogen atoms and/or by one or multiple groups of the type -C(O)O-, -OC(O)-, -C(O)- and/or -OC(O)O-, and/or can be functionalized by one or multiple hydroxyl groups and/or mercapto groups; or an amide of a carboxylic acid or an imide of a cyclic dicarboxylic acid, and
b) Reacting said aminotriazine of the general formulae (I) with at least one ammonium salt of the general formulae (II)
[(R7R8H2N+]nXn-
wherein R7 and R8 linear or branched C1-C20-alkyl, C5-C20-cycloalkyl, or C1-C20-alkylsubstituted C5-C20-aryl or cyclic amines, or wherein R7 and R8 together form an alkyl ring, wherein in each case one or multiple carbon atoms can be substituted by one or multiple oxygen atoms, sulphur atoms and/or substituted nitrogen atoms and/or by one or multiple groups of the type -C(O)O-, -OC(O)-, -C(O)- and/or -OC(O) O- and/or can be functionalized by one or multiple hydroxyl groups and/or mercapto groups, and wherein R7 and R8 can be the same or different;
wherein Xn- is an anion of an organic or inorganic acid, and
wherein n ≥1, in particular 1, 2 or 3, and
c) wherein the reaction takes place in a salt melt of the at least one ammonium salt of the general formuale (II).
