Definitions
- the invention relates to a process for the production of bleach activator granules from one or more ammonium nitriles, wherein the ammonium nitrile is granulated together with a binder and, if appropriate, further additives in the presence of water in a pneumatically generated fluidized bed and dried at the same time.
- the fluidized bed granules are characterized by a very uniform morphology, high abrasion resistance, good storage stability and high active substance contents.
- Bleach activators are important components in compact detergents, stain removers and machine dishwashing detergents. Conventional bleach activators at 40 ° C to 60 ° C enable a bleaching result comparable to that of boilers by reacting with hydrogen peroxide donors (mostly perborates, percarbonates, persilicates and perphosphates) to release an organic peroxycarboxylic acid.
- hydrogen peroxide donors mostly perborates, percarbonates, persilicates and perphosphates
- the achievable bleaching result is determined by the type and reactivity of the peroxycarboxylic acid formed, the structure of the bond to be hydrolyzed, and the water solubility of the bleach activator.
- bleach activators Many substances are known in the art as bleach activators. Usually these are reactive organic compounds with an O-acyl or N-acyl group, already in the washing powder mixture, favored by the residual moisture present, with the bleaching agent, e.g. Sodium perborate can react if both components are unprotected.
- bleach activators are, for example, N, N, N ', N'-tetraacetylethylenediamine (TAED), nonanoylcaprolactamphenylsulfonate ester (APES), glucose pentaacetate (GPA), xylose tetraacetate (TAX), acyloxybenzenesulfonate (e.g.
- nonanoyloxybenzene sulfonate (4-nonanoyloxybenzene sulfonate ( SBOBS), sodium trimethylhexanoyloxybenzenesulfonate (STHOBS)), diacetyldioxohexahydrotriazine (DADHT), tetraacetylglucoluril (TAGU), tetraacetylcyanoic acid (TACA), di-N-acetyldimethylglyoxin (ADMG) and 1-phenyl-3-acetylhydantoin (PAH) and nitrilotriacetate.

- the proportion by weight of ammonium nitrile alone, based on the finished, dry, uncoated granules is generally 1 to 50% by weight, preferably 10 to 40% by weight, particularly preferably 15 to 35% by weight.
- Suitable binders are cellulose and starch and their ethers or esters, for example carboxymethyl cellulose (CMC), methyl cellulose (MC) or hydroxyethyl cellulose (HEC) and the corresponding starch derivatives, but also film-forming polymers, for example polyacrylic acids or their salts.
- Powdery anionic components in particular alkanesulfonates, are also particularly suitable as binders in the sense of this invention.
- the amount of binder, based on the finished granules can be 1 to 45% by weight, preferably 5 to 30% by weight.
- the granules according to the invention additionally contain further additives, preferably acid additives, which reduce the hygroscopicity and sensitivity to hydrolysis of the ammonium nitrile.

- Particularly suitable acidic additives are polyacrylic acid, polymaleic acid or copolymers of acrylic acid and maleic acid (Sokalan ® types).
- the amount of acidic additive is such that the proportion of the acidic additive in the finished granulate is approximately 0 to 30% by weight, preferably 1 to 20% by weight, in particular 10 to 18% by weight.
- the process according to the invention can in principle be carried out by metering all components separately or together in solid form into the fluidized bed apparatus and adding water for the granulation. Another possibility is that all components are entered into the fluidized bed apparatus separately or together in the form of aqueous solutions or suspensions. In practice, various variants of these methods are preferred, as described below. Since the ammonium nitriles are hygroscopic and therefore difficult to isolate in solid form, it is advisable to use these ammonium nitriles in the invention
- an aqueous spray slurry is made
- Ammonium nitrile, another bleach activator, binders and acidic additive produced at room temperature, in a stirred tank with stirring with a (mobile) Ultra-Turrax, optionally heated to a temperature of 25 ° C to 85 ° C, using a suitable pump (e.g. peristaltic pump ) pumped to the nozzle and sprayed into the fluidized bed from below.

- the dust content of the finished granules, as they occur in the process according to the invention, can also be returned to the fluidized bed as a solid. In principle, this recycling of the dust components is possible in all variants of the method according to the invention.
- Such an additional solids feed for example of dusty fine fractions of the finished granules or of powdery ones
- Formulation components for example TAED, can also be advantageous in order to increase the germ concentration in the fluidized bed.
- the addition takes place either before the atomization of the ammonium nitrile solution or preferably simultaneously with this.
- the solid can also be added together with the ammonium nitrile solution, the mixing of these liquid components preferably taking place either before the atomization or directly in the nozzle.
- Ground germ material is preferably metered in, preferably with a grain size ⁇ 1250 ⁇ m.
- the finished granulate is advantageously discharged from the fluidized bed by classifying the size of the granules.
- This classification can be carried out via a central tube with an opposite air flow (classifier air), which is regulated in such a way that only particles of a certain particle size are discharged from the fluidized bed and smaller particles are retained in the fluidized bed.
- the particles discharged from the gas stream above the fluidized bed are separated (e.g. filter or cyclone), fine dust entrained by the gas, if necessary, can be removed in a downstream separator, e.g. Wet scrubbers are separated. The separated dust is fed back into the fluidized bed in the area of the spray nozzle, where it is wetted again.
- Granules preferred according to the invention have a d50 value between 0.4 and 2.5 mm.
- the grain fraction that is greater than 1.4 mm is returned. This coarse fraction can either be added as a solid component to the fluidized bed after grinding or it is dissolved again and sprayed into the fluidized bed.
- the air flowing in from below is composed of the heated or unheated classifier air and the heated soil air.
- the soil air temperature is preferably between 85 and 95 ° C, preferably between 90 and 93 ° C.
- the fluidized air cools down due to heat losses and the heat of vaporization of the constituents of the solvent. This sets the temperature of the layer mass in the fluidized bed to 50 to 70 ° C., preferably 60 to 63 ° C.
- the air outlet temperature is preferably between 55 ° C and 65 ° C.
- the water content of the products can be set within wide limits.
- drying takes place simultaneously with the granulation in the fluidized bed.
- the drying means that the water content of the granules is ⁇ 2% by weight and the bleach activator content is> 50% by weight, based on uncoated co-granules.
- Round fluidized bed apparatuses which are preferably used have base plates with dimensions of at least 0.4 m.
- fluidized bed apparatuses are preferred which have a base plate with a diameter between 0.4 m and 3 m, for example 1, 2 m or 2.5 m.
- the fluidized bed apparatus can have a rectangular shape.
- a perforated base plate or a conid ur plate, a wire mesh or a combination base made of a perforated plate with a grid can be used as the base plate.
- the granules obtained according to the invention are directly suitable for use in detergents and cleaning agents.
