Definitions
- the invention relates to the use of alkyl polyglycosides for deinking waste paper.
- Waste paper is now used in large quantities to produce newspaper and hygienic paper, for example.
- brightness and color are quality features.
- the printing inks must be removed from the printed waste paper. This is usually done using the so-called deinking process.
- deinking process are carried out in technically customary plants for processing waste paper, which are provided with additional devices for separating the detached ink particles. There are two important steps:
- the opening of the waste paper This is the process of shredding the waste paper. For example, it can be induced in an aqueous medium by adding mechanical energy (stirring).
- the fraying is accompanied by the detachment of the ink particles. These particles disintegrate into very small particles with a particle size of 0.1 to 1,000 ⁇ m and are in finely dispersed form.
- a paper stock suspension in the form of a gray paper pulp is obtained.
- This step of the deinking process can be carried out by washing out or by flotation.
- the flotation deinking process is of particular importance. In general, fatty acids or soaps are used as ink collectors in Central Europe.
- Waste paper is also increasingly used for the production of higher quality paper types, such as graphic paper and SC paper, or as a replacement for cellulose.
- the purity of the deinked material is an additional criterion.
- the number and specific area of dirt spots can be regarded as a measure of the purity.
- a number of surface-active substances are known from the patent literature as flotation collectors for deinking waste paper.
- alkoxylated fatty alcohols or fatty acid polyglycol ethers are mainly used used.
- other nonionic compounds with very different chemical structures are described.
- alkyl polyglycosides to deink waste paper and in particular to remove dirt spots from waste paper is not known from the literature to date.
- formulations containing alkyl polyglycosides for general or special paper-technical applications is generally known, for example their suitability
- the object of the present invention was to provide new collectors or collector mixtures which enable a high flotative discharge of dirt spots.
- alkyl polyglycosides which belong to the class of nonionic surfactants, alone or in combination with other collectors, are suitable for the sustainable removal of dirt spots from waste paper.
- the present invention therefore relates to the use of alkyl polyglycosides (I)
- R is a linear, saturated alkyl radical with 8 to 22 carbon atoms and (G) x a glycoside or oligoglycoside radical with a degree of oligomerization x of 1 to 10, for deinking waste paper.
- Alkyl glycosides of the given formula (I) have long been known surface-active substances which can be prepared from sugars and aliphatic, primary alcohols with 8 to 22 carbon atoms with acetalization.
- Preferred sugar components are glucose, but also fructose, mannose, galactose, telose, gulose, allose, old rose, idose, arabinose, xylose, lyxose, libose and mixtures thereof.
- acetalization products of glucose with fatty alcohols which are obtainable, for example, from natural fats and oils by known processes, in particular with linear, primary, saturated and unsaturated fatty alcohols having 8 to 22 carbon atoms, are preferred because of the easy accessibility and the good application properties.
- R is very particularly preferably an alkyl group having 8 to 14 carbon atoms.
- the average degree of oligomerization is preferably in the range from 1 to 1.5.
- the extent of the removal of printing inks from printed wastepaper can be increased when the inventive alkyl polyglycosides in combination with, for example, Ci0-22 "F eu acids or their alkali metal or alkaline earth salts of C6_22 ethoxylated alkyl alcohols, ethoxylated alkyl phenols, cationic polymers, eg polydimethylaminomethacrylate and / or copolymers, the total amount of these optional components is between 0.05 and 1.0% by weight, based on air-dry paper stock.
- printing inks for example newspaper printing inks, letterpress inks, offset printing inks, illustration gravure inks, flexographic inks, laser printing inks and / or packaging inks from printed waste papers, for example newspapers, magazines, computer papers, magazines, brochures, forms, telephone books and / or catalogs remove.
- the waste papers which are deinked in the presence of the alkylpolyglycosides to be used according to the invention are distinguished by high degrees of whiteness and good removal of dirt spots.
- Paper artificial office waste mixture of: 35% copy paper 35% laser paper (HP-Laserjet II / III) 30% merchandise (Hermes, sorted) All papers were naturally aged.
- Pulper paper mass: 110 g (air dry)
- Glucopon 600 was used alone and in combination with SP 85/61 as the compound according to the invention.
- stearic acid collector B1
- the collectors were each used in the pulper in an alkaline formulation. The dosage in percent is based on the waste paper used.
- Table 1 The results of the white and dirt spot measurement after flotation are summarized in Table 1.
- Glucopon 600 was again used alone and in combination with SP 85/61.
- stearic acid collector B1
- the collectors were used in the pulper with a reduced recipe. The dosage in percent is based on the waste paper used.
- Glucopon 600 in combination with SP 85/61 was used as the compound according to the invention.
- stearic acid collected B1
- the collectors were used in the cell directly before the flotation without any additional chemicals ("neutral" recipe).
- the dosage in percent is based on the waste paper used.
- Exposure temperature 45 ° C
- Glucopon 600 and Glucopon 215 were used as the compound according to the invention.
- a nonionic collector was used for comparison.
- the collectors were used in the pulper with an alkaline recipe. The dosage in percent is based on the waste paper used. 13

Abstract
Les alkylpolyglycosides décrits répondent à la formule générale (I): R(G)x, dans laquelle R désigne un radical alkyle saturé linéaire de 8 à 22 atomes de carbone et (G)x désigne un radical glycoside ou oligoglycoside d'un degré d'oligomérisation x de 1 à 10. Ces alkylpolyglycosides se prêtent particulièrement bien pour désencrer du vieux papier.
