Definitions
- Bleach activators are taken to mean compounds which react in aqueous solutions containing hydrogen peroxide or perhydrates to form peracids which have a bleaching action.
- the particularly effective bleach activators include N-acylated amines, amides and glycolurils, as are known, for example, from DE-AS 11 62 967, DE-AS 12 91 317, DE-OS 20 38 106 and DE-AS 15 94 865.
- DE-AS 11 62 967 it is proposed to provide these bleach activators with a water-soluble coating agent before further use, in particular before use in detergents and bleaching agents, wherein the coating agent can consist, for example, of carboxymethyl cellulose.
- This coating agent dissolved in water, can be sprayed onto the activator in finely divided form, after which the coated material is dried.
- the recommendation is made to granulate the activator before coating, but there are no indications as to how and with which granulation aids this should be carried out. If one works according to the specifications of DE-AS 11 62 967 and sprays such a bleach activator, for example tetraacetylethylene diamine, with an aqueous carboxymethyl cellulose solution in a granulator, considerable problems arise. This is because aqueous solutions containing more than 5 percent by weight of carboxymethyl cellulose can no longer be handled in industrial granulation processes because of their high viscosity and gel-like nature.
- a process for the production of coated, granulated bleach activators in which the activator is first mixed dry with a suitable coating or granulation agent and sprayed in a second step with water or water-soluble granulation aids or film formers and is granulated.
- a suitable coating or granulation agent for the preparation of the dry premixes, either water-soluble framework salts customary in detergents, such as water of crystallization, are used phates, polyphosphates, carbonates and silicates of alkali metals or water-insoluble fillers such as silica, magnesium silicate or magnesium oxide are proposed.
- the same water-soluble salts which bind water of crystallization can also be used as granulation aids or the dry premixes can be sprayed with an aqueous solution of film-forming substances such as cellulose derivatives or other water-soluble polymers of natural or synthetic origin and granulated at the same time.
- this process is only useful for the production of granules with a comparatively low content of bleach activators, that is to say those with less than 50 percent by weight.
- the granules can therefore only be used in areas where the high proportion of additives does not interfere.
- the invention is based on the object of developing a process for the production of readily pourable, uniformly coated and thus very stable bleach activator granules which have a substantially higher content, for example one of 90 percent by weight and more, of active substance.
- the invention with which this object is achieved is a process for producing a storage-stable, bleach activator-containing granules by dry mixing a powdered bleach activator from the class of N-acylated amines, amides, diketopiperazines and glycolurils with a powdered granulating aid, moistening the dry Premixed with an aqueous solution of the granulating aid and granulating the moist mixture in a niche and granulating device, characterized in that for the preparation of a granulate containing 90 to 98 percent by weight of bleach activator and 10 to 2 percent by weight of granulating aid, based on anhydrous constituents Bleach activator, which is a medium grain Size from 0.01 to 0.8 mm, in a first mixing stage with 50 to 100 percent of the total granulation aid to be used, which consists of a compound from the class of water-soluble cellulose ether, starch and starch ether and as a pourable powder with an average grain
- Average grain size of 0.01 to 0.8 mm is to be understood as meaning that in which more than 50 percent by weight, preferably at least 80 percent by weight of the particles have a grain size of 0.01 to 0.8 mm and not more than 25 percent by weight , preferably not more than 10% by weight have a grain size of 0.8 to at most ii6 mm and not more than 25% by weight, preferably not more than 10% by weight have a grain size of less than 0.01 mm.
- the grain size of the fine particles is not limited at the bottom, but dust-fine particles can also be present. The additional use of such dusty fractions, which are common in technical, unclassified powder products with a broad grain spectrum, represents an additional advantage of the process.
- N-acylated amines, diamines, amides and glycolurils are suitable as bleach activators.
- These are, for example, tetraacetylmethylene diamine, tetraacetylethylene diamine, diacetylaniline, diacetyl-p-toluidine, 1,3-diacetyl-5,5-dimethylhydantoin, tetraacetylglycoluril, tetrapropionylglycoluril, 1,4-diacetyl-2,5-diketo-piperazine -Diacetyl-3,6-dimethyl-2,5-diketopiperazine.
- Tetraacetylethylenediamine is preferably used as the bleach activator.
- the powdery bleach activator is mixed with a part of the granulation aid, which is also in powder form.
- the proportion of the granulation aid used in this stage is 50 to 100, preferably 80 to 95. Weight percent of the total granulation aid used. Accordingly, the total amount or only part of the granulation auxiliary can be added in the 1st mixing stage.
- the second variant, in which only part of the granulation aid is dry-mixed and the rest is introduced as a solution in the second stage, is the preferred method of operation.
- the average grain size of the granulation aid is 0.01 to 0.8 mm according to the above definition.
- the grain size of the powdered granulation aid is expediently as large or smaller than the grain size of the bleach activator.
- the particle size of the granulating aid is advantageously 0.01 to 0.4 mm, the proportion of particles with a particle size of 0.4 to 1.6 mm 25 Weight percent and in particular 10 weight percent does not exceed.
- the granulation aid consists of a water-soluble cellulose ether, water-soluble starch or a water-soluble starch ether.
- cellulose ethers are celluose, methylcellulose, ethylcellulose, hydroxyethyl cellulose, methylhydroxyethylcellulose, methylhydroxypropyl *, carboxymethyl cellulose (as the sodium salt) and methyl carboxymethyl cellulose (Na salt).
- depolymerized starch can be considered as starch.
- the two powdery components can be mixed in conventional batch-wise or continuously operating mixing devices, which are generally equipped with rotating mixing elements. Depending on the effectiveness of the mixing device, the mixing times for a homogeneous mixture are generally between 30 seconds and 5 minutes.
- powdery disintegrants which are common in the tablet industry can also be added, provided that the cellulose and starch ethers used do not automatically develop a certain explosive effect.
- Usable disintegrants are, for example, partially degraded starch, starch ether, polyvinylpolypyrrolidone, formaldehyde casein and swellable magnesium aluminosilicates (Veegum). The proportion of such disintegrants can be 0 to 2 percent by weight of the anhydrous granules.
- the dry powder mixture is then moistened with water or an aqueous solution of the remaining granulating aid and granulated.
- the mixer of the first mixing stage is also suitable for a granulation process, the mix can remain therein during the granulation process.
- a pelletizer for example a pelletizing drum or onto a rotating pelletizer, and to carry out the pelletizing process there or to complete it.
- part of the granulating liquid is expediently introduced into the mixer towards the end of the first mixing stage in order to moisten the material to be mixed and to counteract the formation of dust. For example, 5 to 70 percent of the granulation liquid is added during the post-mixing and 95 to 30 percent of the liquid during the subsequent granulation.
- the granulating aid used in the second mixing and granulation stage is preferably used in a 0.5 to 5 percent by weight solution. Solutions with a higher concentration and containing up to 10 percent by weight of granulation aids are only recommended if they are sufficiently low-viscosity. If sodium carboxymethyl cellulose is used in a provenance as is usually used in detergents, the concentration is advantageously not more than 4 percent by weight.
- the amount of granulation liquid applied is to be measured in such a way that moist granules are formed which are not yet prone to caking. This is achieved when the water content of the moist granules is between 10 and 35, preferably 15 to 25, weight percent. Powder mixtures with a small grain spectrum and a higher proportion of powdered granulating aid can absorb larger amounts of granulating liquid than less fine-grained mixtures with a small proportion of granulating aid.
- a dye or a white pigment can be added to the dry powder mixture or the granulating liquid for coloring or to cover the inherent color of the raw materials.
- a dye or a white pigment can be added to the dry powder mixture or the granulating liquid for coloring or to cover the inherent color of the raw materials.
- generally 0.01 to 0.1 percent by weight, based on the finished product, of dye or pigment is sufficient.
- the water content of the mixture is then reduced to less than 2, preferably less than 1 percent by weight.
- the excess water can be removed by drying with the addition of heat, the temperature of the granules expediently not exceeding 100 ° C. and below the melting temperature of the bleach activator. Dryers that do not adversely change the granular structure of the product are suitable, for example tray, vacuum or fluidized bed dryers.
- the dried granules should contain less than 2, preferably less than 1 percent by weight of water.
- the Extraction of the excess water also by mixing the moist granules with such dehydrating, essentially water-free or low-water salts.
- Such salts are sodium tripolyphosphate, sodium sulfate, sodium carbonate, sodium silicate and low-water sodium aluminosilicates capable of ion exchange and their genes. The amount to be used depends on the water binding capacity of the salts concerned and the water content of the moist granules.
- the mixing ratio of tripolyphosphate to moist granules is, for example, 1: 3 to 1: 1.5, in particular 1: 2 to 1: 1.
- Mixing can be carried out in conventional mixers or granulating devices, with the addition of Production of the moist granules used, equipped with mixing devices mixing device can be used immediately. In this way, simplified, in particular energy-saving, processing is possible since the necessary drying stage can be saved.
- Suitable foam inhibitors are customary known defoamers, preferably polysiloxanes, and mixtures thereof with microfine silica. Examples of these are polydimethylsiloxane with a content of approximately 1 to 10 percent by weight of microfine silica. The proportion of such polysiloxane foaming can be 1 to 5 percent by weight, preferably 2 to 4 percent by weight, based on the finished granulate.
- the defoamer can be added in the first mixing stage; however, the defoamer can also be dispersed in the granulating liquid which, in order to avoid segregation processes, should contain part of the granulating aid in this case.
- the granules produced in the manner indicated have a favorable grain spectrum. Any overlap and fine fractions can be screened off and returned to the process after grinding the coarse fractions.
- the granules are easy to pour, non-sticky and very stable considering the complete coating of the activator particles. Its high proportion of active substance, 90 and more percent by weight, is particularly advantageous. They can be used with advantage in detergents, bleaches, oxidizers and disinfectants and retain their good properties even when mixed with the active ingredients contained in these agents.
- Tetraacetylethylenediamine with an average grain size of 0.01 to 0.8 mm was used as the bleach activator.
- the grain fraction between 0.8 and 1.6 mm was 5 weight percent, the fraction under 0.01 mm 10 weight percent.
- Example 42.0 kg of the powdery tetraacetylethylenediamine used in Example 1 were in a drum mixer equipped with rotating mixing elements (LöDIGE mixer) with 2.24 kg Na carboxymethyl cellulose of the grain size given in Example 1 (88.2 percent of the total amount used) for 2 minutes mixed and then sprayed with continuous mixing with a solution of 170.4 g Na carboxymethyl cellulose in 5.51 kg water (3 percent by weight) for the purpose of binding dust-like components.
- the mix was transferred to a continuously operating mixing granulator (capacity 800 kg / h).
- the outlet of this mixer was connected to the inlet via conveyor belts so that the product could be circulated.
- the majority of the granules were dried in a vacuum dryer at 50 torr over 24 hours to a water content of less than 1 percent by weight. 3 kg of the moist granules were dried in a fluidized bed dryer with air having an inlet temperature of 57 ° C. for 10 minutes to the same degree of drying. In both cases, the proportion of the granules with a grain size of 0.5 to 1.5 mm was 65 percent by weight. The rollover and fine fractions were sieved out and, after grinding the coarse fractions, entered into the subsequent granulation process.
- 91.45 parts by weight of tetraacetylethylenediamine which had the following grain size (in percent by weight), were obtained in accordance with the preparation procedure given in Example 1: mixed with 3.048 parts by weight of a polysiloxane defoamer (consisting of 93 percent by weight of polydimethylsiloxane and 7 percent by weight of silanized microfine silica) and 4.8 parts by weight of Na carboxymethyl cellulose. Then, through the hollow drive shaft of the mixer, 0.629 parts by weight of sodium carboxymethyl cellulose in the form of a 3% strength aqueous solution were fed in over the course of 5 minutes, and the granulation process was then continued for a further 1 minute.
- Example 4 was repeated, but the polysiloxane defoamer had been dispersed in the aqueous granulation liquid containing carboxymethyl cellulose. In terms of its properties, the product corresponded to that of Example 4.
- Example 42.0 kg of the powdery tetraacetylethylenediamine used in Example 1 were in a drum mixer equipped with rotating mixing elements (L ⁇ DIGE mixer) with 2.24 kg Na carboxymethyl cellulose of the grain size given in Example 1 (88.2 percent of the total amount used) for 2 minutes mixed and then sprayed with continuous mixing with a solution of 170.4 g Na carboxymethyl cellulose in 5.51 kg water (3 percent by weight) for the purpose of binding dust-like components.
- the mix was transferred to a continuously operating mixing granulator (capacity 800 kg / h).
- the outlet of this mixer was connected to the inlet via conveyor belts so that the product could be circulated.
- 4.3 kg of a 3% solution of Na-carboxymethyl cellulose (corresponding to 129 g) were fed in through the rotating shaft of the granulation mixer.
