- the detergent mixtures according to the invention are preferably used in anhydrous form, for example in the form of powders, granules, extrudates or needles.
- Spray neutralization / spray drying Conventional techniques can be used to produce the powders. It is possible, for example, to subject the acidic sulfation products of the fatty alcohols and fatty alcohol ethoxylates to spray neutralization together or separately and to add anhydrous glycosides and / or polyhydroxy fatty acid amides to the dry powders. It is also possible to prepare aqueous mixtures of the components and to spray-dry them together. Likewise, already dried powders of the individual components can be processed into the detergent mixtures, for example in a paddle mixer from Lödige or a spray mixer from Schugi. For details of the spray drying or spray neutralization of surfactants, reference is made to ROEMPP Chemistry Lexicon, 9th edition, Thieme-Verlag, Stuttgart, 1992, p. 4259/4260.
- superheated steam drying is to be understood as a special spray drying in the absence of atmospheric oxygen in the presence of superheated steam.
- the principle of this new technical method has been disclosed by the applicant in its German patent application DE-Al 40 30 688. The method is based on the principle that, by condensing the superheated steam on the cooler feed and releasing the heat of condensation to the material to be dried, the aqueous drop spontaneously heats up to the boiling point of the water under working conditions, ie at normal pressure to temperatures of about 100 ° C takes place. This boiling temperature is maintained as the minimum temperature during the entire drying period in the material drop.
- a desired effect of the superheated steam drying of the detergent mixtures to be used according to the invention can be seen in the fact that a dried material with a high inner surface is obtained which is particularly easy to dissolve or disperse in water.
- the closed system works with a water vapor circuit stream from which the evaporated water portion of the feed is extracted, while the amount of energy given off in particular in the drying step is fed back to the circuit stream. While in conventional spray drying working at higher temperatures is always associated with the risk of partial charring of the material to be dried, the absence of atmospheric oxygen makes drying temperatures of 200 to 250 ° C. readily possible.
- the stripped water vapor partial stream can advantageously be used as service steam for other use after the cleaning of carried-along material portions.
- SKET granulation A further possibility is to subject the detergent mixtures to so-called SKET granulation. This is to be understood as granulation with simultaneous drying, which is preferably carried out batchwise or continuously in the fluidized bed.
- the surfactants can preferably be introduced into the fluidized bed at the same time or in succession via one or more nozzles in the form of aqueous pastes.
- Fluidized bed apparatuses which are preferably used have base plates with dimensions of 0.4 to 5 m.
- the SKET granulation is preferably carried out at fluidized air speeds in the range from 1 to 8 m / s.
- the granules are preferably discharged from the fluidized bed via a size classification of the granules.
- the classification can take place, for example, by means of a sieving device or by means of an opposed air flow (classifier air) which is regulated in such a way that only particles of a certain particle size are removed from the fluidized bed and smaller particles are retained in the fluidized bed.
- the inflowing air is usually composed of the heated or unheated classifier air and the heated soil air.
- the soil air temperature is between 80 and 400, preferably 90 and 350 ° C.
- a starting mass for example sodium sulfate or SKET granules from an earlier test batch, is initially introduced at the start of the SKET granulation.
- the water evaporates from the surfactant paste, resulting in dried to dried germs which are coated with further amounts of surfactant, granulated and in turn dried at the same time.
- the detergent mixtures are homogenized and solidified in a screw press. The extrusion takes place via a perforated disk, so that press strands are formed which can be mechanically comminuted to extrudates or needles of the desired shape and dimension by known processes.
- Auxiliaries and additives are understood to mean the non-surfactant components of the recipes for commercially available toilet blocks, which are mixed with the detergent mixtures and then brought into the desired shape.
- the detergent mixtures are generally used in anhydrous form. For easier plasticization, however, they can be used as Auxiliary water in an amount of 1 to 10, preferably 2 to 6 wt .-% - based on the mixture - are added.
- auxiliaries and additives are inorganic salts, in particular sodium sulfate, sodium carbonate and / or sodium chloride, the proportion of which can total 25 to 75, preferably 30 to 60% by weight, based on the end product.
- detergent mixtures in the form of SKET granules are used which, for example, contain the required proportion of sodium sulfate due to the production process.
- Solid or liquid builders such as, for example, zeolite A, nitrilotriacetate, ethylenediaminetetraacetate or sodium citrate, are also of further importance as additives. Their proportions can make up 5 to 15, preferably 8 to 12,% by weight, based on the end product.
- the toilet blocks usually also contain colorants and fragrances, usually in amounts of 1 to 5% by weight, based on the end product.
- the detergent mixtures according to the invention can be used as surfactant components for the production of toilet blocks. Products on this basis are characterized by a high solubility delay, ie a long service life improved foam resistance and easier processing.
- the detergent mixtures can also be used to produce preservative-free powders for hand-washing pastes.
