Abstract:
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung einer Verbindung der allgemeinen Formel (I) durch Umsetzung einer Verbindung der allgemeinen Formel (II) mit einer Verbindung der allgemeinen Formel (III) (RO) 2 CO oder einer Verbindung der Formel (IV) in Gegenwart eines Zeolithen vom NaY- Faujasit Typ, wobei Ar, X, R und n wie in Anspruch 1 angegeben definiert sind.
Abstract:
The present invention refers to dyestuffs of the formula (I) wherein A is carbon linked moieties especially chromophores; Y is N or C X 1 is halogen or tertiary ammonium, especially pyridinium; L 1 is a carbon based linking unit, optionally interrupted by 0-atoms or optionally substituted N-atoms, especially ethylene or propylene R 0 , R 1 , R 2 and R 3 are independently hydrogen, C 1 to C 4 alkyl groups optionally substituted, or R 2 is a group of the general formula (a*), or R 3 independently is a group of the general formula (b*): (a*), (b*) wherein A 1 and A 2 have one of the meanings of A. Y 1 and Y 2 have independently one of the meanings of Y X 2 and X 3 have independently one of the meanings of X 1 , R 4 , R 5 , R 6 and R 7 are independently hydrogen or C 1 to C 4 alkyl optionally substituted. L 2 and L 3 are carbon based linking units, optionally interrupted by O-atoms or optionally substituted N-atoms, especially ethylene or propylene. R 1 and R 2 may be linked together such as to form a cyclic structure together with -N-L 1 -N + . If R 2 is a group of formula (a*) or (b*) then R 1 and R 3 may be linked together such as to form a cyclic structure with -N-L 1 -N + , or R 6 and R 3 may be linked together such as to form a cyclic structure with -N + -L 3 -N-, or R 4 and R 3 may be linked together such as to form a cyclic structure with -N + -L 2 -N-, but not simultaneously, processes for the preparation of said dyesstuffs and their use for dyeing and printing hydroxy- and/or carboxamido-containing fiber materials.
Abstract:
The present invention refers to azacalixarenes of the formula (I) wherein each T independently is a 1,3,5-triazine ring, optionally substituted; each A independently is an optionally substituted aromatic or heteroaromatic ring-based unit; each L independently is a direct bond or a linking atom or linking group of atoms; each R independently is an aliphatic bridging component; M ≥ 1; n = 0, 1 or 2; where m ≥ 2 if n = 0; and wherein at least one of T, A, R, L independently contains one or more water-solubilising groups, a process for their production and their use for dyeing and printing hydroxyl- and/or carboxamido-containing material.
