Description

The The present invention relates to a textile-sparing process for Washing textiles in the presence of a persoxy-containing Bleaching agent and a bleach-enhancing transition metal complex and the use of cation-complexing, cation-exchanging or cation-precipitating substances to reduce textile damage of bleach-enhancing transition metal complexes in the washing of textiles and products containing peroxygen Bleaching agent, bleach-enhancing transition metal complex and cation-complexing, cation-exchanging or cation-precipitating Contain substances.

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 effect 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 Strive for energy-saving washing and bleaching processes Application temperatures significantly lower in recent years 60 ° C, especially below 45 ° C down to to the cold water temperature in importance.

at these low temperatures leaves the effect the previously known activator compounds usually recognizable to. There was therefore no lack of aspirations for To develop this temperature range more effective bleaching systems. A starting point for this results from the use of hydrogen peroxide-supplying Compounds together with transition metal salts and complexes as so-called bleach catalysts. These are, presumably because of the high reactivity of them and the peroxygen compound resulting oxidizing intermediates, but the risk of oxidative textile damage. The use of such transition metal catalysts in detergents has been difficult in practice so far, because then the damage to the tissue significantly higher is than in a peracid-forming conventional system bleach and bleach activator.

The The present invention is aimed at washing textiles the damage of the textile when using bleach-active Catalysts lower, without the bleaching power is essential to influence.

Alkaliphosphat is the summary term for the alkali metal in particular sodium and potassium) salts of various phosphoric acids, in which one can distinguish metaphosphoric acids (HPO ₃ ) _n and orthophosphoric H ₃ PO _{4 in} addition to high molecular weight representatives. The phosphates combine several advantages: they act as alkali carriers, prevent lime deposits on machine parts or lime incrustations in fabrics and also contribute to the cleaning performance. Sodium dihydrogen phosphate, NaH ₂ PO ₄ , exists as a dihydrate (density 1.91 gcm ^-3 , melting point 60 °) and as a monohydrate (density 2.04 gcm ^-3 ). Both salts are white powders which are very soluble in water and which lose their water of crystallization when heated and at 200 ° C into the weak acid diphosphate (disodium hydrogen diphosphate, Na ₂ H ₂ P ₂ O ₇ ), at higher temperature in sodium trimetaphosphate (Na ₃ P ₃ O ₉ ) and pass on Madrell's salt. NaH ₂ PO _{4 is} acidic; It arises when phosphoric acid is adjusted to a pH of 4.5 with sodium hydroxide solution and the mash is sprayed. Potassium dihydrogen phosphate (potassium phosphate primary or monobasic potassium, potassium biphosphate, KDP), KH ₂ PO ₄ , is a white salt of density 2.33 gcm ^-3 , has a melting point of 253 ° (decomposition to form (KPO ₃ ) _x , potassium polyphosphate) and is slightly soluble in water. 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 prepared by evaporating a solution of 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 z. 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: fused or annealed 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 100 g of water dissolve at room temperature about 17 g, at 60 ° about 20 g, at 100 ° around 32 g of the salt water-free salt; after two hours of heating the solution to 100 ° caused by hydrolysis about 8% orthophosphate and 15% diphosphate. 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 much Insoluble metal compounds (also lime soaps, etc.). Pentakalium triphosphate, K ₅ P ₃ O ₁₀ (potassium tripolyphosphate), is marketed, for example, in the form of a 50% strength by weight solution (> 23% P ₂ O ₅ , 25% K ₂ O). 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. These arise, for example, when hydrolyzed sodium trimetaphosphate with KOH: (NaPO ₃ ) ₃ + 2KOH → Na ₃ K ₂ P ₃ O ₁₀ + H ₂ O

These are according to the invention exactly like sodium tripolyphosphate, Potassium tripolyphosphate or mixtures of these two can be used; also mixtures of sodium tripolyphosphate and sodium potassium tripolyphosphate or mixtures of potassium tripolyphosphate and sodium potassium tripolyphosphate or mixtures of sodium tripolyphosphate and potassium tripolyphosphate and sodium potassium tripolyphosphate can be used according to the invention.
