Description

The present invention relates to the use of creatine to reduce the damage of bleach-enhancing transition metal complexes in treating cellulosic material, particularly in the washing of textiles, a gentle process for treating cellulosic material in the presence of a peroxygen bleaching agent and a bleach-enhancing transition metal complex, and bleaching agent containing oxygenated oxygen , bleach-enhancing transition metal complex and creatine.

Inorganic peroxygen compounds, particularly hydrogen peroxide and solid peroxygen compounds which dissolve in water to release hydrogen peroxide, such as sodium perborate and sodium carbonate perhydrate, have long been used as oxidizing agents for disinfecting and bleaching purposes. The oxidation effect of these substances in dilute solutions depends strongly on the temperature; Thus, for example, with H ₂ O ₂ or perborate in alkaline bleaching liquors only at temperatures above about 80 ° C, a sufficiently fast bleaching of soiled textiles. At lower temperatures, the oxidation effect of the inorganic peroxygen compounds can be improved by adding so-called bleach activators, for the numerous proposals, especially from the classes of N- or O-acyl compounds, for example, polyacylated alkylenediamines, especially tetraacetylethylenediamine, acylated glycolurils, in particular tetraacetylglycoluril, N- acylated hydantoins, hydrazides, triazoles, hydrotriazines, urazoles, diketopiperazines, sulfururamides and cyanurates, in addition carboxylic acid anhydrides, in particular phthalic anhydride, carboxylic acid esters, in particular sodium nonanoyloxy-benzenesulfonate, sodium isononanoyloxy-benzenesulfonate and acylated sugar derivatives, such as pentaacetylglucose, have become known in the literature , By adding these substances, the bleaching action of aqueous peroxide liquors can be increased so much that even at temperatures around 60 ° C substantially the same effects as with the peroxide solution alone at 95 ° C occur. The damage to the tissue remains in a frame acceptable to the consumer.

In the search for energy-saving washing and bleaching processes in recent years application temperatures well below 60 ° C, especially below 45 ° C down to the cold water temperature in importance.

At these low temperatures, the effect of the previously known activator compounds usually decreases noticeably. There has therefore been no lack of efforts to develop more effective bleaching systems for this temperature range. A starting point for this arises through the use of hydrogen peroxide-providing compounds together with transition metal salts and complexes as so-called bleach catalysts. These, however, presumably because of the high reactivity of the resulting from them and the peroxygen compound oxidizing intermediates, but the risk of oxidative textile damage. The use of such transition metal catalysts in detergents has been hitherto difficult in practice, because then the damage to the tissue is significantly higher than in a peracid-forming conventional system of bleach and bleach activator. The same applies mutatis mutandis to bleaching operations that are carried out in the production of cellulosic material, such as pulp or paper.

The present invention aims at the bleaching treatment of cellulose-containing material, for example when washing cotton-containing textiles, to reduce the damage to the cellulose-containing material, for example a cotton-containing textile, when using bleach-active catalysts, without significantly influencing the bleaching performance.

The invention in a first aspect is a process for the bleaching treatment of cellulose-containing material, in particular in the production of pulp or paper or in the washing of cotton-containing textiles, in the presence of a persoxy-containing bleaching agent and a bleach-enhancing transition metal complex, which is characterized in that Presence of creatine is performed.

Disodium hydrogen phosphate (secondary sodium phosphate), Na ₂ HPO ₄ , is a colorless, very slightly water-soluble crystalline salt. It exists anhydrous and with 2 moles (density 2.066 gcm ^-3 , loss of water at 95 °), 7 moles (density 1.68 gcm ^-3 , melting point 48 ° with loss of 5 H ₂ O) and 12 moles water ( Density 1.52 gcm ^-3 , melting point 35 ° with loss of 5 H ₂ O) becomes anhydrous at 100 ° C and, upon increased heating, passes into the diphosphate Na ₄ P ₂ O ₇ . Disodium hydrogen phosphate is prepared by neutralization of phosphoric acid with soda solution using phenolphthalein as an indicator. Dipotassium hydrogen phosphate (secondary or dibasic potassium phosphate), K ₂ HPO ₄ , is an amorphous, white salt that is readily soluble in water. Trisodium phosphate, tertiary sodium phosphate, Na ₃ PO ₄ , are colorless crystals which have a density of 1.62 gcm ^-3 as dodecahydrate and a melting point of 73-76 ° C (decomposition), as decahydrate (corresponding to 19-20% P ₂ O ₅ ) have a melting point of 100 ° C and in anhydrous form (corresponding to 39-40% P ₂ O ₅ ) have a density of 2.536 gcm ^-3 . Trisodium phosphate is readily soluble in water under alkaline reaction and is evolved by evaporation Solution prepared from exactly 1 mole of disodium phosphate and 1 mole of NaOH. Tripotassium phosphate (tertiary or tribasic potassium phosphate), K ₃ PO ₄ , is a white, deliquescent, granular powder of density 2.56 gcm ^-3 , has a melting point of 1340 ° and is readily soluble in water with an alkaline reaction. It arises, for example, when heating Thomasschlacke with coal and potassium sulfate. Despite the higher price, the more soluble, therefore highly effective, potassium phosphates are often preferred over the corresponding sodium compounds in the detergent industry. Tetrasodium diphosphate (sodium pyrophosphate), Na ₄ P ₂ O ₇ , exists in anhydrous form (density 2.534 gcm ^-3 , melting point 988 °, also indicated 880 °) and as decahydrate (density 1.815-1.836 gcm ^-3 , melting point 94 ° with loss of water) , For substances are colorless, in water with alkaline reaction soluble crystals. Na ₄ P ₂ O ₇ is formed on heating of disodium phosphate to> 200 ° or by reacting phosphoric acid with soda in a stoichiometric ratio and dewatering the solution by spraying. The decahydrate complexes heavy metal salts and hardness agents and therefore reduces the hardness of the water. Potassium diphosphate (potassium pyrophosphate), K ₄ P ₂ O ₇ , exists in the form of the trihydrate and is a colorless, hygroscopic powder with a density of 2.33 gcm ^-3 , which is soluble in water, the pH being 1% Solution at 25 ° 10.4. Condensation of the NaH ₂ PO ₄ or of the KH ₂ PO ₄ gives rise to relatively high molecular weight sodium and potassium phosphates, in which cyclic representatives, the sodium or potassium metaphosphates and chain types, the sodium or potassium polyphosphates, can be distinguished. In particular, for the latter are a variety of names in use: melting or annealing phosphates, Graham's salt, Kurrolsches and Madrell's salt. All higher sodium and potassium phosphates are collectively referred to as condensed phosphates. The technically important pentasodium triphosphate, Na ₅ P ₃ O ₁₀ (sodium tripolyphosphate), is an anhydrous or with 6 H ₂ O crystallizing, non-hygroscopic, white, water-soluble salt of the general formula NaO- [P (O) (ONa) -O] _n -Na with n = 3.

In the preparation of pentasodium triphosphate, phosphoric acid is reacted with sodium carbonate solution or sodium hydroxide solution in a stoichiometric ratio and the solution is dehydrated by spraying. Similar to Graham's salt and sodium diphosphate, pentasodium triphosphate dissolves many insoluble metal compounds (including lime soaps, etc.). Pentakaliumtriphosphat, K ₅ P ₃ O ₁₀ (potassium tripolyphosphate), for example, in the form of a 50 wt .-% solution (> 23% P ₂ O ₅ , 25% K ₂ O) in the trade. The potassium polyphosphates are widely used in the washing and cleaning industry. There are also sodium potassium tripolyphosphates which can also be used in the context of the present invention.
