Definitions
- the invention relates to a stabilized, aqueous suspension of synthetically produced zeolite of type A, a process for the production of this suspension on an industrial scale and the use of the suspension for the production of low-phosphate and phosphate-free powder detergents.
- the stabilizers of DE-OS 2527 388 are used together with a stabilizing aid from the group of non-surfactant organic and inorganic water-soluble salts with molecular weights below 1,000, for example sodium sulfate, sodium citrate, sodium tripolyphosphate, sodium carbonate, etc.; this gives greater flexibility in adapting the viscosity of the suspensions to the storage and processing conditions.
- German Offenlegungsschrift 30 21 295 recommends the use of nitrilotriacetate sodium salt; on the other hand, water glass solutions, gel-like aluminum oxides or silicon oxides, soaps of the chain length C 5 -C 22 , or sodium salts of the type of washing alkalis, including sodium hydroxide, are described in Japanese laid-open publications 54 064 504, 55 127 499, 57 034017, 57 061 615 and 57 067 697 suggested.
- the requirements for the properties of the zeolite suspensions depend to a certain extent on the type of washing and cleaning agents for which they are to be used; However, it has been found that the zeolite suspensions, in order to be usable on an industrial scale, should have the following individual properties: stability in the widest possible temperature range, which ranges from room temperature or below to at least 70 ° C .; a sediment, if it arises after prolonged storage, must be able to be stirred up again using technical stirrers; the viscosity should remain low even in the lower temperature range, ie
- the stabilized aqueous zeolite suspension that of industrially produced A-type zeolite, water and a stabilizer system with water-insoluble nonionic surfactant as suspension stabilizer and an additional stabilizing agent, can be significantly improved in its properties if the stabilizing agent consists of an anionic sulfate surfactant from the group
- the proportions of the stabilizer system consisting of the suspension stabilizer and the stabilizing aid in the suspension according to the invention are preferably in the range from 0.5 to 5% by weight. Amounts of 1 to 3% by weight and in particular those of 1.5 to 2.5% by weight, based in each case on the stabilized aqueous zeolite suspension, are particularly preferred. Within these quantitative ranges, the ratio of the nonionic surfactant to the anionic sulfate surfactant is in the range from 5: 1 to 1: 5, and preferably in the range from 3: 1 to 1: 1.
- the suspension according to the invention is low-viscosity over the entire temperature range from room temperature to 80 ° C. and can be stirred and pumped without problems.
- Room temperature is understood here to mean the temperatures in the storage and processing rooms which fluctuate in the range from 15 to 25 C, depending on the season. Even after storage for several days in this temperature range, especially at elevated temperatures of 50 to 70 ° C, only a small amount of soft sediment is formed, which can be easily stirred up again.
- the suspension according to the invention also shows excellent rheological properties, which are characterized above all by a narrow viscosity range and by perfect flow behavior.
- the zeolite suspension In some technical processing equipment for zeolite suspensions for the production of powdered detergents, the zeolite suspension must be warmed, ie. above room temperature. It is then crucial for usability that the suspension remains stable over a longer period of time at elevated temperature and does not disintegrate.
- the pH value of the aqueous zeolite suspension which is at pH 11 to 14, is not changed significantly by the stabilizer system according to the invention comprising nonionic surfactant and anionic sulfate surfactant.
- the pH fluctuations caused by the free alkali present in industrial production have a significantly reduced influence on the stability of the suspension when the stabilizer system according to the invention is used.
- a further reduction in viscosity is achieved by a targeted lowering of the pH by adjusting the suspensions to a pH of less than 12, in particular from 9 to 1 1, and adjusting this pH by adding an acidic salt.
- the addition of acidic salt is generally in the range from 0.2 to 3% by weight, based on the finished suspension in which this salt is then present as a neutral salt.
- the stabilizer system according to the invention has no negative influence on the calcium binding capacity of the zeolite.
- the stabilizer system according to the invention consists of a mixture of detergent substances known per se; the zeolite suspension thus stabilized is therefore not only useful for the production of a large number of detergents and cleaning agents, but these detergent active substances which enter the finished detergents and cleaning agents via the zeolite suspension make a contribution to the washing and cleaning success of the finished product.
- the neutral salts formed from the acidic salts are also generally used as components of detergents and cleaning agents.
- Aqueous zeolite suspensions with an addition of dispersants from the group of water-soluble nonionic surfactants and synthetic organic surfactants of the sulfonate type are known from US Pat. No. 3,254,034 (Dwyer et al). These known zeolite suspensions are used to exchange the sodium cations for the rare earth cations and then to work up the exchanged zeolites into catalysts. In these known suspensions, which are constantly moved, special storage stability is not important; It is important, however, that only readily soluble compounds which can easily be separated off again after the cation exchange by filtration can be considered as organic additives.
- the nonionic surfactant defined above is generally in amounts of 0.2 to 3% by weight and the stabilizing aid according to a) and / or b) according to the above definition in amounts of 0.2 to 3% by weight is present, the total amount of nonionic surfactant and stabilizing aid being in the range 0.5 to 5% by weight, based on the stabilized zeolite suspension.
- the maximum amounts mentioned in order to achieve the improved viscosity and storage properties rather, total amounts of up to 2.5% by weight are sufficient for most further processing purposes.
- the pH of aqueous zeolite suspensions which do not contain a stabilizer or a stabilizer which does not influence the pH is from pH 11 to pH 14, i.e. there is an excess of alkali. This alkali excess is often welcomed for further processing into detergents and cleaning agents because it is included in the final detergent product as an alkali reserve. If the pH value is lowered by the further addition of the acid salt, the corresponding neutral salts are formed, which, when the acid salts are selected appropriately, are also considered to be typical washing and cleaning agent components because they impart advantageous properties to the finished product.
- German Offenlegungsschrift 26 52 409 recommends adding acid or an acid salt to the freshly prepared zeolite suspension to such an extent that the pH does not drop below 9.0. This measure improves the buffering capacity of the zeolite.
- the references mentioned also explain that special precautions must be taken when admixing the acid, so that there is no local over-concentration of acid and the acid-sensitive zeolite structure is not destroyed.
- German Offenlegungsschrift 26 15 698 describes the addition of a non-surfactant, organic or inorganic low molecular weight salt as a stabilizing aid to a stabilized zeolite suspension
- European Offenlegungsschrift 870 describes the improvement of the rheological properties of zeolite suspensions by adding sodium sulfate -Neutral salt is known, but this prior art, neither as a single document nor when considered together, suggests adding an acidic salt for targeted pH adjustment to an aqueous zeolite suspension already stabilized by a stabilizer system comprising a nonionic and a sulfate surfactant, and thus to the desired narrow range of low viscosity, which is not temperature-dependent.
- the anionic salt for targeted pH adjustment to an aqueous zeolite suspension already stabilized by a stabilizer system comprising a nonionic and a sulfate surfactant, and thus to the desired narrow range of low viscosity, which is not temperature-dependent.
- Sulfate surfactants according to a) preferably the sulfuric acid monoester of a primary C 12 -C 18 alkanol in the form of the water-soluble salt, and as
- Sulfate surfactant according to b) preferably the sulfuric acid monoester of a primary C 12 -C 18 alkanol reacted with ethylene oxide, likewise in the form of the water-soluble salt.
- the degree of ethoxylation of the sulfate surfactants according to b) is generally on average 1 to 15 moles of ethylene oxide per mole of the alkanol, preferably 1 to 4 moles of ethylene oxide.
- the C 12 -C 18 fatty alcohols which can be prepared from natural fats are particularly preferred. Such derivatives combine the particularly good stabilizing properties with those of perfect biodegradability and good accessibility from natural renewable raw materials.
- Typical representatives of the sulfate surfactants used according to the invention are, for example, the products tallow alcohol sulfate (TAS) (where "tallow alcohol” stands for the hydrogenated tallow fatty alcohol mixture of the chain length range C 14 -C 18 ); Lauryl alcohol sulfate; Coconut alcohol sulfate (KOAS) (where "coconut alcohol” stands for the C 12 / C 18 cut from natural coconut fatty alcohol); Lauryl alcohol ether sulfate (LAES) (made from a C 12 / C 14 fatty alcohol reacted with 2 to 3 moles of ethylene oxide); coconut / tallow alcohol sulfate (made from coconut and tallow alcohol in a 1: 1 ratio); Cetyl / stearyl alcohol sulfate (Applicant's Lanette E product); Tallow alcohol 2EO sulfate.
- TAS tallow alcohol sulfate
- tallow alcohol stands for the hydrogenated tallow fatty alcohol mixture
- Sulfate surfactants are present as sodium salts or as ethanolamine salts or triethanolamine salts.
- the practically water-insoluble nonionic surfactants used as suspension stabilizers are those compounds whose cloud point, if determined by the method DIN 53917 in aqueous butyl diglycol solution, is 90 ° C and below, preferably 85 ° C and below. These nonionic surfactants are described in detail in German Offenlegungsschaben 25 27 388 and 26 15 698.
- Typical examples of these practically water-insoluble nonionic surfactants are, for example, the verbin fertilize tallow alcohol polyglycol ether with 5 moles of ethylene oxide (TA 5E0); coconut alcohol (C 12 -C 18 cut ) polyglycol ether with 4 moles of ethylene oxide; Oleyl alcohol polyglycol ether with 5 moles of ethylene oxide; Oleyl / cetyl alcohol polyglycol ether with 7 moles of EO (made from an alcohol mixture with an iodine number of 50 to 55); C 14 -C 15 oxo alcohol polyglycol ether with 4 moles of EO; Nonylphenolp ⁇ lyglykolether with 5 moles of ethylene oxide.
- T 5E0 the verbin fertilize tallow alcohol polyglycol ether with 5 moles of ethylene oxide
- the amount of the acid salt is generally in the range from 0.2 to 3% by weight, based on the finished suspension. In individual cases, the additional quantities can also be above or below these range limits. In any case, the amount of acid salt added depends on the pH of the moist zeolite filter cake or the zeolite suspension at the end of the zeolite production process. The pH value is therefore not only dependent on the choice of the zeolite production process, but also on the degree of washing out of the zeolite with water.
- the acidic salt is added in solid form or in the form of a concentrated aqueous solution in small portions with stirring.
- the acid salts which can be used according to the invention are primarily inorganic acid salts, in particular the acid salts of sulfuric acid, carbonic acid, phosphoric acid and polyphosphoric acids, boric acid and silica.
- the acid salts of polyvalent organic acids such as, for example, citric acid, diglycolic acid, gluconic acid, polyacrylic acid, nitrilotriacetic acid, hydroxyethane diphosphonic acid and analogous hydroxyalkane or aminoalkane polyphosphonic acids, can be used, although less preferred.
- the acid salts of other inorganic and organic acids are also suitable; however, those acidic salts are considered preferred which are present after the partial neutralization as neutral salts which play an advantageous role in building up the detergent and cleaning agent or during the washing or cleaning process.
- Acid salts are accordingly the salts of polyvalent acids which have at least one alkali or asmonium cation and react with the alkali in the aqueous zeolite suspension with partial neutralization.
- the zeolite A used according to the invention can be prepared by numerous known processes by hydrothermal synthesis from sodium silicate and sodium aluminate solutions or from destructured kaolin and sodium hydroxide.
- zeolite A is generally obtained as a moist filter cake with about 50 to 60% water content. Because of its thixotropic properties, this filter cake can be easily stirred immediately after production and mixed directly with the suspension stabilizer.
- the suspensions according to the invention can be prepared by simply mixing the components.
- the aqueous suspension of the zeolite which is still moist and undried from its production is preferably used by converting the moist filter cake obtained after separating the mother liquor and washing with water into a flowable suspension by stirring. A further addition of water is generally not necessary.
- the stabilizing agents are used in the case of the nonionic surfactants in undiluted form and in the case of the anionic sulfate surfactants in the form of the commercially available technical aqueous concentrates of the sodium salts or as granules, flakes or pasta.
- the acidic salts are mostly added in powder form.
- the amount of water additionally introduced with paste-like concentrates is small in terms of quantity, so that it does not significantly influence the zeolite concentration in the stabilized suspension.
- the suspensions according to the invention can be prepared with zeolite concentrations of at least 20% by weight; however, for economic reasons, ie in order to save transport and energy costs, for example Set the water content in the suspensions as low as possible. For example, efforts will be made to adjust the zeolite content to values above 40% by weight and, if possible, to values around 50% by weight.
- the suspensions according to the invention are generally prepared at elevated temperatures, ie at about 50 ° C., which speeds up the mixing process.
- an already dried zeolite powder can also be used for the production of the suspensions according to the invention if the zeolite filter cake that is still moist from the production is not available.
- the stabilized zeolite suspensions are used as liquid raw materials according to the usual manufacturing processes for such agents.
- the stabilized zeolite suspensions for the production of powdered detergents by the method of hot spray drying, the so-called slurry batch being prepared with the zeolite suspension and then converted into a detergent powder in spray towers in the usual way.
- the suspension according to the invention can also be converted into a spray-dried powder as such or after the addition of further detergent substances.
- the resulting powder product can be stirred again with water to a stable suspension, which increases the practical application possibilities for the suspension according to the invention.
- Stabilizer system consisting of nonionic surfactant and anionic sulfate surfactant
- a moist filter cake of zeolite NaA with the following properties was used to prepare the stabilized suspensions: Zeolite NaA content, based on the anhydrous substance (residue on ignition after heating to 800 ° C. for one hour): 47.0%;
- the stabilized suspension had the following composition:
- TA 5 EO 0.8% by weight of tallow fatty alcohol sulfate (TAS), 46.0% by weight of zeolite NaA, 0.35% by weight of sodium oxide, the rest being water.
- TAS tallow fatty alcohol sulfate
- the Brookfield viscosity was determined: 20 revolutions per
- the viscosity behavior of the suspension according to the invention extends practically over the entire temperature range.
- Example 1 describe bench tests of three suspensions according to the invention in comparison to a known suspension (see Example 1).
- the stored suspensions are classified according to the criteria of sedimentation, i.e. Sediment formation and consistency assessment.
- B W + low sediment formation, soft, easy to stir
- B W sediment formation with a soft consistency, easy to stir
- B M sediment formation with medium consistency, difficult to stir
- B H sediment formation with hard consistency, cannot be stirred.
- the storage tests were carried out at room temperature, 35 ° C, 50 ° C and 70 ° C, respectively. The viscosity of the suspensions was also measured at these temperatures before storage; No change in viscosity was observed during the storage period in the case of the completely homogeneous suspensions and in the case of the again stirred suspensions with a soft sediment consistency.
- TA 5 EO and TAS have the meanings given in Example 1.
- KOAS coconut fatty alcohol sulfate sodium salt (C 14 -C 18 cut ).
- LAES lauryl alcohol (C 12 / C 14 ) ether sulfate sodium salt (with approx. 2 mol EO).
- Stabilizer system composed of nonionic surfactant and anionic sulfate surfactant and with the addition of an acidic salt
- the zeolite A filter cake used had the following properties:
- Zeolite A content 46%; Calcium binding capacity: 160 mg CaO / g;
- Particle size 100% smaller than 25 ⁇ ; 95% less than 10 ⁇ ; 71% less than 5 ⁇ ; 18% less than 3 ⁇ ; average particle diameter: 4.0 ⁇ ; Alkali content: 0.35% by weight.
- the stabilized suspension had the following composition:
- TAS tallow fatty alcohol sulfate
- the Brookfield viscosity was determined: 20 revolutions per minute; Spindle depending on the viscosity range.
- Example 6 the acidic salt NaHSO 4 is replaced by NaH 2 PO 4 , or the stabilizer TA 5 is reacted with a mixture of oleyl / cetyl alcohol with an iodine value of 50 to 55 in the same quantity, reacted with 4 mol or 6 mol ethylene oxide in a ratio of 1 : 1, replaced, then similar viscosity and stability properties are also observed.
