Definitions
- the invention relates to a process for the preparation of amino-containing cellulose derivatives by reacting alkali cellulose with amino group-containing reagents, starting from unsubstituted cellulose or cellulose derivatives in a reaction step, water-soluble or water-dispersible reaction products can be obtained.
- Chitosan 2-amino-2-deoxy-cellulose
- Chitosan is the only widely available cationic polysaccharide that can be used in a wide range of applications. It is used, inter alia, as acid-stable thickener in cosmetic preparations, as paper auxiliaries and as chelating agent and flocculant.
- the extraction of this natural polysaccharide is a complex process, which is reflected in high prices of the products. The high price has hitherto hindered the widespread use of chitosan.
- cellulose and its derivatives primarily hydroxyethyl-containing cellulose ethers, for example, by the reaction with aminoalkyl chlorides of the general formula Cl- (CH 2 ) I i-NR 2 can be converted into amino group-containing cellulose derivatives.
- aminoalkyl chlorides of the general formula Cl- (CH 2 ) I i-NR 2 can be converted into amino group-containing cellulose derivatives.
- larger amounts of organic solvents are used, as described, for example, in US Pat. No. 2,623,042. In this case, only slight degrees of etherification are achieved in most cases and the amount of unwanted by-products is high.
- DE-A 1 946 722 shows that this problem can be counteracted by using kneaders.
- predominantly water-soluble cellulose derivatives were kneaded in a solvent / water mixture and reacted with N- (2-chloroethyl) -N, N-diethylammonium chloride.
- Substitution degrees of 0.3 to 1.0 per anhydroglucose unit were achieved.
- a disadvantage here is that in the technical implementation, the safety in dealing with combustible and volatile organic solvents (in the said patent primarily peroxide-forming dioxane) can be ensured only at increased cost guaranteed.
- the workup and recovery of aqueous solvents and solvent mixtures requires high investment eg in distillation columns and requires disposal costs, eg for distillation residues.
- the invention was therefore based on the object to provide an environmentally friendly, safe and admirably ⁇ favorable process for the preparation of amino group-containing cellulose derivatives.
- the invention therefore provides a process for the preparation of amino-containing cellulose derivatives by reacting alkalized cellulose or alkalized cellulose derivatives with reagents of the general formula
- X is a leaving group, preferably chlorine, bromine, iodine or a sulfonic acid radical R'SC> 3 , where R 'is an aromatic or aliphatic radical having 1 to 24 C atoms, for example para-toluyl or methyl,
- n must be at least 2
- R 1 and R 2 independently of one another are aliphatic or branched or cyclic, optionally heteroatom-substituted alkyl or aryl substituents having 1 to 24 C atoms or H or two radicals R 1 and R 2 may form a ring together with the nitrogen,
- cellulose of the most varied origin and characteristic profiles is used, for example, in chips, fiber or powder form.
- Cellulose derivatives can also be used.
