Herrn Professor D r . habil. Burkart Philipp zum 65. Geburtstag gewidmetDie vorliegende Ubersicht enthalt eine zusammenfassende Darstellung von Untersuchungen zur Einfuhrung reaktiver funktioneller Gruppen in die Cellulose. Unter synthesechemischen Gesichtspunkten werden heterogen verlaufende Reaktionen betrachtet, die sich vor allem durch die Erzielung eines moglichst hohen durchschnittlichen Substitutionsgrades, einen weitgehend selektiven Verlauf oder die Anwendung neuer praparativer Techniken und Reagenzien auszeichnen.

Zntroduction of reactive functional groups into cellulose by chemical modification under heterogeneous conditions. ReviewInvestigations on the introduction of reactive functional groups into cellulose a t heterogeneous conditions of reaction are reviewed. From the organic chemist's point of view the survey considers reactions characterized by yielding a high degree of substitution, a selective course of functionalisation, or the use of modern preparation techniques and new reagents.

“…An alternative commercially unattractive approach employed a p ‐nitroanilino‐triazinyl compound ( 5 ) with a subsequent reduction step to yield the desired amino group [41]. Additionally, Zemaitaitis and Zdanavicius [42] reacted cellulose with substituted epoxypropylamine in the presence of sodium hydroxide solutions, and Burba and Lieser [43] and Cho et al [44] described the reaction of cellulose with p ‐aminophenyl‐ β ‐sulphatoethylsulphone ( 6 ) in either dimethylsulphoxide or dimethylformamide.…”

Functionalisation of lyocell. Part 1: Amination of lyocell with m‐phenylenediaminesulphonic acid derivatives

A series of four colourless, water‐soluble agents, based on m‐phenylenediaminesulphonic acid, and designed to aminate lyocell, have been synthesised. Each agent carried one or two aromatic amino groups ortho to a water solubilising sulphonic acid group, together with one or two electrophilic groups. The electrophilic groups studied were dichlorotriazinyl, monochlorotriazinyl, vinylsulphonyl and triazinyl betaine. The agents were applied to lyocell by padding techniques, and neutral‐exhaustion dyeing of the aminated fibres, with low, medium and high reactivity reactive dyes, in the presence of salt, were performed. Only the high reactivity dichlorotriazinyl dye gave encouraging results. The aminated fabrics, containing aromatic amino groups with an o‐sulphonic acid, were insufficiently nucleophilic to allow significant covalent bonding with the low/medium reactivity dyes at both 60 and 80 °C.

Immobilization of affinity ligands, proteins, enzymes and other functional groups by azo coupling is based on the high reactivity of the support-carrying diazonium groups towards both low- and high-molecular weight compounds containing certain groupings such as phenols, imidazole and some other heterocycles, thiols and amines. The precursor of diazonium group is a diazotizable amine on the matrix. Remarkable progress in its preparation was achieved by application of (4-amino-phenyl)-(2-sulphatoxyethyl) sulphone-type reagents for functionalization of the matrix. A similar type of amine precursor is prepared by the reaction of monosubstituted sulphanilamide with epoxide-containing matrix. The presence of a SO2 group in the para position to diazonium group of these supports (after diazotization) enhances reactivity in azo coupling. 'Reversed' azo coupling is the reaction of a matrix containing functional groups capable of reacting with diazonium groups of a ligand. Preparation of a suitable matrix and examples of diazotizable ligands are given.
