Definitions
- the invention relates to a process for the production of free-flowing detergent and cleaning agent granules and / or partial granules, in which aqueous alkyl and / or alkenyl oligoglycoside pastes are present in one in the presence of surfactants and / or further detergent and cleaning agent ingredients Turbinen ⁇ dryer with rotating internals dries and granulates at the same time.
- Powdery washing and cleaning agents are usually produced by spray drying.
- an aqueous slurry (“slurry") of the contents, for example surfactants, builders and adjusting agents, is conveyed into the spray tower via pumps and sprayed through nozzles located in the top of the tower. Rising air with a temperature of .250 to 300 ° C dries the slurry and evaporates the adhering water, so that at the outlet of the tower a practically water-free granular or powdery Product is received. Details of this process are described, for example, in ROEMPP Chemie Lexikon, Thie e Verlag, Stuttgart, Vol. V, 1992 under the keyword “spray drying”.
- the object of the invention was therefore to develop a new process for the production of detergent and cleaning agent granules and / or partial granules which is free from the disadvantages described.
- the invention relates to a process for the production of free-flowing detergent and cleaning agent granules and / or partial granules, which is characterized in that aqueous alkyl and / or alkenyl oligoglycoside pastes in the presence of anionic and / or nonionic surfactants and / or usual detergent and cleaning agent ingredients in a turbine dryer with rotating internals dewatered and granulated at the same time.
- Alkyl and / or alkenyl oligoglycosides which are suitable as starting materials for the process according to the invention follow the formula (I),
- R1 for an aliphatic hydrocarbon radical with 8 to 22 carbon atoms and 0, 1, 2 or 3 double bonds
- R2 for an alkylene group with 2 to 4 carbon atoms
- Alkyl and / or alkenyl oligoglycosides are preferred which are derived from aldoses or ketoses and, in particular, from glucose because of their easy availability.
- the preferred alkyl oligoglycosides are thus the alkyl oligoglucosides.
- Alkyl oligoglycosides with an average degree of oligomerization p of from 1.1 to 3.0 are preferred; those alkyl and / or alkenyl oligoglycosides whose degree of oligomerization is less than 1.7 and in particular between 1.2 and 1.4 are particularly preferred.
- the radical R- can be derived from saturated and / or unsaturated primary alcohols having 8 to 22, preferably 8 to 10 or 12 to 18, carbon atoms.
- Typical examples are capric alcohol, 2-ethylhexanol, caprylic alcohol, lauryl alcohol, isotridecyl alcohol, myristyl alcohol, cetyl alcohol, palmoleyl alcohol, stearyl alcohol, isostearyl alcohol, oleyl alcohol, elaidyl alcohol, petroselinyl alcohol, linolyl alcohol, bino alcohol alcohol, linoleyl alcohol, linoleyl alcohol, linoleyl alcohol, the this Can contain alcohols in different amounts. Alkyl and / or alkenyl oligoglucosides based on are preferred
- alkyl and / or alkenyl oligoglycosides can also be present in the form of their adducts with 1 to 30 moles of ethylene, propylene and / or butylene oxide.
- Alkyl and / or alkenyl oligoglycosides are known substances which can be obtained by the relevant methods of preparative organic chemistry.
- a process for their preparation is, for example, the acid-catalyzed acetalization of glucose with fatty alcohols.
- the alkyl and / or alkenyl oligoglycosides are used in the form of aqueous pastes which can have a water content of 20 to 80, preferably 30 to 50% by weight, based on the paste.
- the anionic surfactants can, for example, be selected from the group consisting of soaps, alkylbenzenesulfonates, olefin sulfonates, alkanesulfonates, alkyl ether sulfonates, alpha-sulfo fatty acids, internal sulfo fatty acids, alpha Ester sulfonates, glycerol ether sulfonates, alkyl sulfates, alkyl ether sulfates with conventional or narrow homolog distribution, glycerol ether sulfates, monoglyceride (ether) sulfates, hydroxy mixed ether sulfates, alkyl oligoglucoside sulfates, isethionates, taurides, sarcosinates, ether carboxylates and sulfosiglycerinate, sulfos becomes.
- soaps alkylbenzenesulfonates,
- nonionic surfactants such.
- B substances which are selected from the group consisting of fatty alcohol polyglycol ethers with conventional or restricted homolog distribution, alkylphenol polyglycol ethers, mixed ethers, amine oxides, sugar esters, sorbitan esters and polysorbates.
- Mixing components are selected from the group consisting of alkali and alkaline earth metal phosphates and phosphonates, zeolites, NTA, EDTA, citric acid, polycarboxylic acids, alkali metal and alkaline earth metal carbonates, sulfates, silicates, for example. borates and citrates. Starch, sucrose, polydextrose, active oxygen carriers, bleach activators, optical brighteners and defoamers.
- the ratio of the individual components to one another is not critical as long as it is ensured that the feed materials can be metered into the turbine mixer without any problems, ie with the aid of conventional pumps or other conveying means.
- Turbine dryers are to be understood as cylindrical drying apparatuses, preferably in a horizontal construction, in which rotating internals at high speed ensure a fine distribution of the dry material.
- these internals are, for example, wings, blades or paddles which are mounted on a rotating shaft (peripheral speed 5 to 25 m / s, preferably 10 to 20 m / s) .
- the actual drying can take place at wall temperatures of 100 to 180 ° C and gas phase temperatures of 150 to 220 ° C, preferably in the presence of air, inert gases such as nitrogen or superheated steam, the heat transfer by convection and the heated wall of the dryer he follows.
- a temperature of the gas phase of 150 to 220 ° C. has proven to be optimal.
- the dry material can be separated off, for example, using a cyclone and / or a bag filter.
- Special features of the turbine dryer to be used according to the invention are thus the short residence time, the narrow residence time spectrum and the high temperature stabilization, which ensure that the dry material is treated as gently as possible, particularly with regard to its composition and color.
- the detergent and cleaning agent granules and / or partial granules obtainable by the process according to the invention have a residual water content of 0.1 to 5% by weight and an advantageously narrow particle size distribution. They are suitable, for example, for producing powder detergents, in which they can be present in concentrations of 10 to 100% by weight, based on the detergents.
- the detergent and cleaning agent granules and / or partial granules were produced in a horizontally arranged turbo dryer (type ES 2050, from Vomm, Milan, Italy) with a turbine diameter of 0.34 m and a turbine length of 2 , 4 m, in which a shaft with blades or blades rotated at high speed.
- a horizontally arranged turbo dryer type ES 2050, from Vomm, Milan, Italy
- aqueous paste 50% by weight aqueous paste (Plantaren ( R ) 600 APG, Henkel KGaA)
- Components A) and B) were continuously introduced at two metering points of the turbine drier which follow one another axially in the direction of flow.
- the mixture was finely distributed in a hot, turbulent air stream and dewatered at the same time.
- the drying temperature was 160 to 180 ° C and was transferred on the one hand by convection and on the other hand via the heated jacket of the dryer.
- the granulated dry material was separated from the gas stream at the outlet of the turbine dryer using a cyclone and a bag filter. A light-colored, free-flowing granulate with a narrow particle size distribution was obtained, the residual water content of which was 1.5% by weight.
- Example 1 was repeated. The following were used as input materials:
