Definitions
- the present invention relates to biopolysaccharide derivatives associated with organic radicals, a process for their preparation and their use.
- Polysaccharides with specific side chains which are particularly capable of binding to cellulose substrates, are well known from the prior art.
- polysaccharides such as, for example, xyloglucans from pea or tamarind seeds
- xyloglucans from pea or tamarind seeds
- This type of binding is primarily known from plant cell walls, but it also serves to give cellulose fibers special properties, for example in the paper and textile industry.
- U.S. Patent 3,297,604 describes polymer compositions containing galactose units in oxidized form, their Carbonyl groups react to form cyanohydrins, disulfite addition compounds, oximes or hydrazones.
- the compositions described in this document can also be used for crosslinking polymers such as guar gum, locust bean gum and in particular cellulose.
- the object of the present invention was to provide polysaccharide derivatives, consisting of a biopolysaccharide backbone and associated organic residues, which are able to bind to cellulose units and which are in particular biodegradable and therefore, from an industrial point of view, represent an ecologically and economically sensible alternative to the previously known treatment agents for cellulose fibers.
- the inventive Polysaccharide derivatives are not only easy to produce according to the task from conventional and extremely environmentally compatible starting compounds, but that they are also excellently suitable for conjugation to cellulose fibers, which was previously only known from corresponding polysaccharide compounds that contain organic residues with a Have molecular weight of at least 5,000.
- the polysaccharide derivatives according to the invention avoid steric problems which occur in particular in the treatment of cellulosic textile fabrics.
- Post-treatment processes can be changed in different degrees, which further extends the field of application of the proposed polysaccharide derivatives.
- the organic radicals preferably contain at least one carboxylic acid (salt) or carboxylic acid ester group and / or at least one carboxylic acid amide group, in particular a carboxylic acid C 6-2 4 alkylamide group.
- Organic radicals which are bonded to the biopolysaccharide via an ether bridge in the ⁇ position to a carboxylic acid (salt) or ester group or to a carboxamide group are particularly preferred.
- Organic radicals which have the general formula (Ia) or (Ib) are particularly preferred. (la) or (Ib)
- R is a C 6- 4 alkyl radical.
- This radical R stands above all for a natural fatty acid radical and can optionally contain one or more double bonds.
- R ' is H, a C 1 - 30 - alkyl radical or a cation, such as a metal, an ammonium group or an organic cation (e.g., Na, K, etc..).
- biopolysaccharide component it is provided according to the invention that it preferably consists of ⁇ - or ⁇ - (1, 4) and / or ⁇ - or ⁇ - (1,3) -glucan units, particularly preferably glucan, mannan and / or xylan units, and most preferably from glucose, mannose, xylose, galactose, guluronic acid, mannuronic acid and / or galacturonic acid units.
- the symbol -O stands for an O atom that comes from the basic structure of the biopolysaccharide component.
- polysaccharide derivatives which, according to the invention, as the basic biopolysaccharide structure, xyloglucans, glucomannans, mannans, galactomannans, ⁇ - or ⁇ - (1, 3), (1, 4) glucans, glucuron, arabino and glucuronoarabinoxylan and in particular guar gum, locust bean gum, xanthan gum, carrageenans, alginates, pectins, starch, cellulose and any derivatives thereof, such as methyl, carboxymethyl, hydroxyalkyl Ethylene glycol and / or propylene glycol derivatives.
- biopolysaccharide component is not subject to any restrictions within the scope of the invention, but it is advisable to choose representatives which have a minimum chain length of 4 sugar units.
- the number of organic residues per monosaccharide unit can be varied within the scope of the present invention and is preferably from 0.01 to 4.
- the present invention also claims a process for their preparation, in which the biopolysaccharide is base-catalyzed with a suitable reagent for introducing the organic radical, preferably with N-alkylmaleamic acid or a salt thereof.
- a suitable reagent for introducing the organic radical preferably with N-alkylmaleamic acid or a salt thereof.
- the maleamic acid should have an alkyl radical with 6 to 24 carbon atoms.
- the present invention also encompasses a process variant in which the maleamide component was cyclized to the maleimide derivative before the actual reaction with the biopolysaccharide.
- the maleamide component according to the present invention can also be cyclized to the succinimide derivative after the reaction with the biopolysaccharide.
- This esterification step can be carried out both before and after the reaction with the biopolysaccharide.
- the polysaccharide derivative in the desired quality can be precipitated after the addition of the organic residue to the biopolysaccharide backbone, for which a mineral acid, for example a dilute hydrochloric acid, is preferably used.
- a mineral acid for example a dilute hydrochloric acid
- the described preparation of N-substituted maleamide acids and maleimides from amines and maleic anhydride follows the known synthesis instructions, as described e.g. from Organic Synthesis, Coll. Vol. IV, 944 are known.
- the addition of alcohols to maleamic acid esters or maleamides is e.g. from R.A. Finnegan and W.H. Mueller, J. Pharm. 1965, 54, 1257-1260.
- the present invention also encompasses the use of the polysaccharide derivatives according to the invention for binding to cellulose fibers. It is preferably used in the context of the invention for textile treatment and particularly preferably as a biodegradable fabric softener.
- the focus of the present invention is on polysaccharide derivatives which have a biopolysaccharide with ⁇ - or ⁇ - (1,4) and / or ⁇ - or ⁇ (-1,3) glucan units as the backbone and which have ether bridges are connected with organic residues which have a molecular weight ⁇ 5,000. Since both Biopolysaccharides as well as the organic residues preferably associated therewith are naturally occurring compounds or toxicologically harmless compounds, the polysaccharide derivatives according to the invention are readily biodegradable products which, particularly from an ecological point of view, are also used in industrial applications, such as textile processing and processing. cause no problems.
