Abstract

Magnesium-mono-peroxy-phthalate-hexahydrate is prepd from, phthalic anhydride, a magnesium source and hydrogen-peroxide (25-35 wt%) in the presence of a complexing agent and a base.

Description

The present invention relates to a novel process for the preparation of magnesium monoperoxyphthalate hexahydrate, and to detergent, detergent and bleach disinfectants containing this compound.

It is known that peroxyacids and their salts with various bases are strong oxidizing agents and thus are well suited for bleaching contaminated textiles and / or as a bleach-disinfectant component of detergents. (The bleaching and disinfecting effects of these oxidants are always present at the same time.)

Previously, various perborates were used as bleaching agents in detergents.

Recently, research has focused on the preparation of compositions for lowering the temperature of the wash. This is mainly due to the widespread use of more heat-sensitive synthetic fibers and energy saving reasons. The above trend is still valid today. This is supported by the fact that while in the United States in the 1970s 50% of the washes were carried out at temperatures above 55 ° C, in 1985 this figure dropped to 10% and is projected to be above 1990 by 1990. the proportion of washes at temperature drops to about 1%.

Lowering the washing temperature is known to reduce the effectiveness of conventional detergents. Perborate bleaching agents are particularly sensitive to temperature changes. For low temperature washes, the decomposition of perborate compounds resulting in the formation of molecular oxygen is of prime importance. The development of molecular oxygen is ineffective in the bleaching process. It is known that phosphonates can be added to detergents to prevent molecular oxygen generation. Other known methods for efficient use of perborates at low temperatures include so-called acyl groups. activators. Under the washing conditions, the acyl group of the activator reacts with the perhydroxylanion liberated from the perborate to form peroxyacid in situ; the latter is a strong oxidizing agent even in the temperature range of 20-40 ° C.

However, the use of a stoichiometrically necessary amount of activator does not, for technical reasons or economic considerations, provide an industrial scale route.

A further disadvantage of the above known methods is that the formation of peroxyacid in the perborate activator system is an uncertain, difficult to control process. In order to improve or control this, further methods employ peroxyacid or a derivative of peroxyacid directly in the detergent. No. 73,541. U.S. Patent No. 4,123,198 to Janos et al., discloses a bleaching composition containing peroxylauric acid urea. This detergent bleaching composition is particularly suitable for low temperature washes according to the patent. However, the composition has several disadvantages. The stability of peroxyl lauric acid is inadequate and the urea present is an environmentally undesirable ingredient. It is known that urea-containing wastewater, like tripolyphosphate, results in eutrophication of living waters.

Of the peroxyacids and water-soluble salts of peroxyphthalic acid and water-soluble salts thereof, which are suitable for providing a suitable bleaching effect, are stable and are well compatible with the other constituents of the detergent. The sodium salt of perperoxyphthalic acid can be prepared by reaction of phthalic anhydride, hydrogen peroxide and sodium carbonate in an aqueous medium at -5 ° C to 0 ° C (Weigan-Hilgetag, Organisch-Chemische Experimentierkunst, 1964, 3, 357). However, the monoperoxyphthalate produced by the above method decomposes relatively rapidly during storage during oxygen depletion. Thus, the method described in the cited literature does not provide monoperoxyphthalic acid or sodium monoperoxyphthalate with stability in the state of the art. According to another method [Ullmann: Encyklopadie dér Technischen Chemie, 4, Yl. Vol. 670, p. 670] by reaction of phthalic anhydride and hydrogen peroxide at 30 ° C in the presence of an ammonium catalyst in 1,2-dichloroethane to produce a high purity of 90% pure monoperoxyphthalic acid. Reproduction of the process gave less than 65% conversion (relative to phthalic anhydride). During the one hour reaction period, 30% of the hydrogen peroxide decomposed due to the evolution of oxygen. Because of the instability of the monoperoxyphthalic acid so produced, it cannot be used as a bleaching component in detergents. Magnesium monoperoxyphthalate hexahydrate (hereinafter "MMPH") is particularly preferably used as a low temperature bleaching agent in terms of safety, stability, and toxicology. According to the literature, the preparation of MMPH is generally carried out by adding to the solution of phthalic anhydride 3-5 times in an organic solvent, first magnesium oxide or magnesium hydroxide, followed by 10-20 mol% excess at a temperature of 5-10 ° C. Hydrogen peroxide 50% by weight is added. The resulting crystalline precipitate is filtered off, washed with organic solvents and then dried under vacuum. No. 4,403,994. U.S. Pat. No. 4,198,195 discloses water, highly concentrated (50-87.5% by weight) hydrogen peroxide, and very high amounts (ca.

Phthalic anhydride and magnesium oxide (10 x) are added to the ethyl acetate mixture at 10 ° C, the temperature is raised to 20-25 ° C, and after stirring for several hours, the excellent MMPH is filtered off, washed with ethyl acetate and dried in vacuo. However, this process has significant disadvantages.

According to the patent, the yield is rather average, ca. 61-65% (based on phthalic anhydride).

- The high concentration of hydrogen peroxide (50-87.5 1%) used is explosive. It is known in the industrial practice that 30% by weight hydrogen peroxide can be handled relatively easily without the risk of explosion, whereas in the treatment of more than 30% hydrogen peroxide by explosion2

EN 209 466 különleges special safety precautions are necessary to reduce the risk.

The resulting MMPH has a high diphthaloyl peroxide content of about 5%.

- The resulting magnesium monoperoxyphthalate hexahydrate has poor stability.

The procedure described above is the same as that described in German Patent No. 3,426,792, except that a basic material is used in the reaction. This has made it possible to carry out the reaction using hydrogen peroxide at a lower concentration, but the yield, purity and stability of the product are still unsatisfactory.

It is an object of the present invention to overcome the drawbacks of the known processes and to provide a process which is feasible under industrial and environmental and safety conditions for the preparation of high purity, high stability MMPH in good yield.

It is a further object of the present invention to provide MMPH produced by the above method, having excellent washing properties and stable detergent, cleaning and bleach disinfectant properties.

SUMMARY OF THE INVENTION The present invention relates to a process for the preparation of magnesium monoperoxyphthalate hexahydrate by reaction of a phthalic anhydride, a source of magnesium and hydrogen peroxide in the presence of a base, using a complexing agent, preferably 25-40 wt% hydrogen peroxide.

The present invention is based on the discovery that the reaction of monoperoxyphthalic acid or its water-soluble salts (sodium, magnesium salt, etc.) with phthalic anhydride and hydrogen peroxide does not yield good yields because under the conditions used, hydrogen peroxide generates molecular oxygen. it decomposes, and this already precludes the achievement of a higher transformation. The decomposition of hydrogen peroxide during the formation of oxygen is particularly intense in the alkaline pH range above 20 ° C. However, the formation of perhydroxyl anion, which is very important for the desired conversion to MMPH, is accelerated in an alkaline medium, but this favorable process is impaired by the decomposition of hydrogen peroxide in an alkaline medium. As a result of the above effects, the desired MMPH is produced only in a moderate yield of 61-65% with a significant amount of unmodified phthalic anhydride which is converted to phthalic acid or magnesium phthalate.

It has been found that when MMPH is prepared from phthalic anhydride and a source of magnesium and hydrogen peroxide in the presence of a complexing agent and a base, the decomposition of hydrogen peroxide is suppressed and at the same time the perhydroxyl anion is produced to such an extent that the desired MMPH is obtained in a very high yield of 85-88%. High yields, on the one hand, significantly improve the economics of the process and, on the other hand, significantly reduce the amount of pollutants in the mother liquor.

Nitrilotriacetic acid, ethylenediamine tetraacetic acid, hydroxyethylenediamine triacetic acid, diethylenetriaminepentaacetic acid, or alkylaminophosphonic acid or a water-soluble salt thereof may be used as complexing agents in the process of the invention.

Preferably, the complexing agent used in the process of the present invention is ethylenediaminetetraacetic acid, ethylenediaminetetramethylene phosphonic acid or diethylenetriaminepentaacetic acid or water-soluble salts thereof. The water-soluble salt is preferably an alkali metal salt, particularly preferably a sodium or potassium salt. In a particularly preferred embodiment of the process, the disodium salt of ethylenediaminetetraacetic acid may be used, e.g. Mavacid ED-4 manufactured by United Chemicals. The complexing agent is used in an amount of at least 0.001 parts by weight based on 1 part by weight of phthalic anhydride. The upper limit of the amount of complexing agent is determined by considerations of economy or practicality.

In the process, bases may be inorganic or organic bases. Preferred inorganic bases are alkali metal hydroxides (e.g., sodium hydroxide or potassium hydroxide), alkali metal carbonates (e.g., sodium carbonate or potassium carbonate) or ammonia. The organic base is preferably triethanolamine. Preferably 0.003-0.007 parts by weight of sodium hydroxide or equivalent amount of the other bases mentioned above are used per part by weight of phthalic anhydride.

Preferred sources of magnesium are magnesium oxide, magnesium carbonate, basic magnesium carbonate or magnesium hydroxide. Generally, 0.10-0.15 parts by weight, preferably 0.13-0.14 parts by weight, of magnesium oxide or equivalent amount of magnesium hydroxide or magnesium carbonate may be used, based on 1 part by weight of phthalic anhydride.

The mixing of the components is preferably carried out under cooling to 5-10 ° C and the reaction is completed by stirring at 10-20 ° C for several hours.

The reaction may be carried out in a preferred inert organic solvent, most preferably ethyl acetate. The reaction may be carried out without ethyl acetate, with appropriate stirring.

In a particularly preferred embodiment of the process of the present invention, the phthalic anhydride and the magnesium source (particularly preferably magnesium oxide) are premixed and added in several portions, preferably in 2 or 3 portions. The reaction mixture is stirred between each addition, usually for approx. 30 to 90 minutes, most preferably about 1 hour. The advantage of the above embodiment is that due to the gradual addition of phthalic anhydride and magnesium oxide, a large excess of hydrogen peroxide is present during the initiation phase important for the side reaction and it suppresses the formation of diphthaloyl peroxide which cannot be incorporated in detergents due to skin irritation. The present invention provides a process according to the invention for known methods

Significantly less diphthaloyl peroxide is produced relative to the compound. A further advantage of adding phosphoric anhydride and a source of magnesium in portions is that it facilitates the removal of the reaction heat that is formed and thus facilitates the control of the reaction.

The hydrogen peroxide is preferably added in the form of an aqueous solution at a concentration of 25 to 35% by weight, more preferably about 25 to about 35% by weight. 30% by weight hydrogen peroxide can be used.

Surprisingly, it was not foreseeable that, due to the characteristic features of the process of the present invention, the yield of MMPH compared to the known processes is about 10%. It will increase by 20%. It is believed that the reason for the very significant conversion improvement lies not only in the fact that the complexing agent inhibits hydrogen peroxide decomposition and increases the stability of the formed MMPH, but also probably enhances the beneficial effect of the alkaline catalyst. This indicates that only 60-65% conversion can be achieved using the alkaline catalyst and the complexing agent separately.

According to a particularly preferred embodiment of the process according to the invention, the following can be done:

Ethyl acetate and 29.5-30.5% aqueous hydrogen peroxide were charged into the apparatus. The mixture is cooled to 35 ° C and then 0.001 to 0.003 parts by weight of a complexing agent, preferably ethylene diamine tetraacetic acid sodium salt, are added to 1 part by weight of phthalic anhydride to be used. Thereafter, 0.0030.007 parts by weight of sodium hydroxide or equivalent amount of sodium carbonate, ammonia or triethylamine (per part by weight of phthalic anhydride) are added. A mixture of phthalic anhydride and magnesium spinning (preferably magnesium oxide) in a weight ratio of 1: 0.10 to 0.15 is added to the mixture with vigorous stirring at 5-10 ° C. The reaction is carried out for 2 to 4 hours at 10-20 ° C. Advantageously, the mixture of phthalic anhydride and magnesium oxide is added in two or three portions at 30-60 minute intervals. After completion of the reaction, water is conveniently added to the reaction mixture to accelerate the hydration of the magnesium monoperoxyphthalate. MMPH is precipitated in a clear, easily filterable form and is easily isolated by filtration or centrifugation. The product on the filter was dried in vacuo after washing with ethyl acetate. The ethyl acetate used is easily separated from the mother liquor and can be recycled in the reaction.

By our process, highly purified crystalline magnesium monoperoxyphthalate hexahydrate is obtained in very good yields. The yield is 85-88% (relative to phthalic anhydride), the product contains 5.3-5.5% active oxygen by iodometry, and the diphthaloyl peroxide content is 2.9-3.2% (as determined by IR spectroscopy). The stability of the product is demonstrated by the fact that its oxygen content remains unchanged when stored at room temperature for one year when kept away from moisture.

The washing, cleaning, bleaching-disinfectant composition containing the magnesium monoperoxyphthalate monohydrate produced by the process of the present invention also has a different effect than the active ingredient obtained by the previously known process. At present, we do not know the exact scientific explanation for this, but assume that there may be a difference in the crystalline structure of the active ingredient or in the incorporation of trace amounts of the complexing agent that produces this beneficial effect. The fact is that the composition according to the invention has a much greater bleach disinfectant effect than the known compositions.

The invention further relates to a bleach based on magnesium monoperoxyphthalate hexahydrate, a stain remover and / or a bleach disinfectant, characterized in that the MMPH produced by the process of the present invention and the surfactants and / or builder components used in such compositions and / or or fillers and / or excipients.

The detergents, bleach disinfectants and stain removers of the present invention have the advantage of high stability. This is because the MMPH used as the bleaching component and produced by the process of the present invention is intimately mixed with the reaction components and the complexing agent during the manufacturing process and therefore the MMPH is very effectively inhibited and the stability of the composition is greatly improved.

Detergents, bleaches, and stain removers of the present invention may contain known components for use in such compositions. The composition contains from 1.5 to 95% by weight of magnesium monoperoxyphthalate hexahydrate, up to 45% by weight of surfactant, up to 70% by weight of building component, up to 90% by weight of filler and up to 16% by weight of excipient.

The following surfactants may be used:

Anionic surfactants, e.g. sulfonates, e.g. alkylaryl sulfonates and alkylbenzene sulfonates, preferably dedecylbenzene sulfonate; sulfonate olefins, alcohol sulfates and sulfated fatty acid alkanolamides; alkyl ether sulfates; phosphate derivatives of ethylene oxide based nonionic surfactants; salts of carboxylic acids.

Cationic surfactants, e.g. quaternary ammonium salts, preferably tetraalkylammonium halides containing at least one C 10 alkyl group.

Nonionic surfactants, e.g. Condensation products of C 8 -C 10 alcohols with ethylene oxide; condensation products of alkyl phenols or alkyl naphthols with ethylene oxide; condensation products of C 10 -C 22 alkanolamides with polyethylene oxide or polypropylene glycol.

Amphoteric surfactants, e.g. aliphatic quaternary ammonium, sulfonium and phosphonium compounds.

Preferred building materials are the following: polyphosphates, preferably sodium tripolyphosphate; aluminum silicates, preferably zeolite A, alkali metal and alkaline earth metal carbonates and silicates, preferably sodium carbonate and sodium metasilicate; oxidizing agents (chemical bleaching agents) such as sodium perborate.

Suitable fillers are preferably inorganic salts (e.g., sodium sulfate or sodium chloride, etc.), ground sand, pumice or powdered earth.
