Definitions
- the invention relates to the use of selected end group-sealed polyethylene glycol ethers as foam-suppressing additives in low-foam cleaning agents.
- the invention aims to provide tools of the type mentioned which combine high effectiveness with physiological harmlessness and biodegradability.
- the new auxiliaries of the invention should in particular also be suitable for effectively suppressing undesirable foam formation in the case of strongly foam-generating cleaning processes, for example spray cleaning, in the range of low temperatures, in particular in the range of room temperature or only slightly elevated temperatures.
- Aqueous cleaning agents intended for use in trade and industry in particular those for cleaning metal, glass and ceramic surfaces, generally contain substances which are able to counteract undesirable foam development.
- foam-suppressing additives is due to the fact that the contaminants detached from the substrates and accumulating in the cleaning baths act as foaming agents.
- anti-foaming agents may also be necessary due to the fact that the cleaning agents themselves Contain components that give rise to undesirable foaming under the specified working conditions.
- anionic surfactants widely used in cleaning agents.
- Addition products of alkylene oxides with organic compounds with reactive hydrogen atoms in the molecule have long been used as foam-suppressing additives.
- addition products of propylene oxide onto aliphatic polyalcohols - see, for example, DE-PS 1 280 455 and DE-PS 1 621 592 - and onto aliphatic polyamines - compare, for example, DE-PS 1 289 597 and DE-PS 1 621 593 - and addition products of ethylene oxide and propylene oxide to aliphatic polyamines, especially ethylenediamine - compare DE-PS 1 944 569 - proven in practice.
- these alkylene oxide addition products also have the alkali stability which is usually required for use in commercial and industrial cleaning agents.
- the compounds in this class are not sufficiently biodegradable to meet the applicable legal requirements.
- the European patent application EP-A-0 322 781 relates to a process for the preparation of a large number of mixed ethers which have a linear or branched C1-C20alkyl radical (R1), hydrogen or a linear or branched, aliphatic, araliphatic or aromatic hydrocarbon radical with 0 to Have 19 carbon atoms (R2) and 2 to 50 ethylene glycol and 0 to 10 propylene glycol units.
- R1-C20alkyl radical R1
- R2 linear or branched, aliphatic, araliphatic or aromatic hydrocarbon radical with 0 to Have 19 carbon atoms (R2) and 2 to 50 ethylene glycol and 0 to 10 propylene glycol units.
- R1-C20alkyl radical R1
- R2 linear or branched, aliphatic, araliphatic or aromatic hydrocarbon radical with 0 to Have 19 carbon atoms (R2) and 2 to 50 ethylene glycol and 0 to 10 propylene glycol units.
- German patent application DE-A 25 56 544 relates to machine dishwashing detergents containing mixed ethers in which R1 for linear or branched alkyl or alkenyl radicals having 6 to 22 carbon atoms, R2 for a tert-butyl radical and n for 5 to 50 ethylene glycol or Propylene glycol units.
- mixed ethers are considered to be particularly advantageous in which R 1 is a linear alkyl radical having 8 to 14 carbon atoms.
- US Pat. No. 3,684,723 relates to detergents containing anionic surfactants, builder salts, soaps and foam-regulating nonionic surfactants of the mixed ether type, which have a very low HLB value in the range from 1 to 4.
- the teaching of the present invention is based on the surprising finding that even more effective auxiliaries of the type concerned here can be obtained by slightly varying the structure of the last-mentioned end group-sealed fatty alcohol polyethylene glycol ethers.
- foam-suppressing additives are often to be carried out at low temperatures, for example in order to carry out an energy-saving pre-cleaning.
- Conventional, foam-suppressing additives are often characterized by the fact that they are very effective in combating foam in the temperature range of approximately 50 ° C. and above, but their use at temperatures of approximately 20 ° C. leads to comparatively weaker foam damping.
- the additives according to the invention described below develop particular effectiveness precisely at lower temperatures and also exhibit this property when they are blended with structurally similar, known components.
- the carbon number of this radical is increased compared to the radicals described above, and is at least 20 carbon atoms.
- Fatty alcohols of natural origin of this type can be obtained in a manner known per se by hydrogenating the upper sections of natural fatty acid mixtures or the methyl esters obtained therefrom.
- the class of Guerbet alcohols is affected by the invention.
- alcohols of this type are formed by the condensation of fatty alcohols with a lower carbon number in the presence of alkali, for example potassium hydroxide or potassium alcoholate.
- the reaction takes place, for example, at temperatures of 200 to 300 ° C and leads to branched Guerbet alcohols, which branch in the 2-position to the hydroxyl group.
- Selected fatty alcohols or also mixtures of different fatty alcohols can be used for the synthesis; the resulting alcohol mixture with a higher carbon number is of correspondingly complex composition.
- 2-octyldodecanol-1 and 2-decyl-tetradecanol-1 and their mixtures can be used as the starting material for the preparation of the polyglycol ethers of the formula (I).
- the end group-capped fatty alcohol polyglycol ethers of the formula (I) are produced in accordance with the specifications of DE-OS 33 15 951.
- the fatty alcohols of higher carbon number described above are advantageously reacted with ethylene oxide in a molar ratio of 1: 6 to 1:20 and then etherified the hydroxyl groups present in the reaction product obtained.
- the reaction with ethylene oxide takes place under the known alkoxylation conditions, preferably in the presence of suitable alkaline catalysts.
- the etherification of the free hydroxyl groups is preferably carried out under the known conditions of Williamson's ether synthesis with n-butyl halides. Accordingly, an example of such a final etherification is n-butyl iodide.
- the invention is not limited to this.
- alkyl halide and alkali for example from 10 to 50%, use the hydroxyl groups to be etherified.
- the end group-capped polyglycol ethers of the formula (I) to be used according to the invention are used in an important embodiment in a mixture with structurally identical polyethylene glycol ethers, but in which the radical R 1 is a straight-chain or branched alkyl or alkenyl radical with 8 to 18 C atoms and n is one Number is from 7 to 12, and preferably from 8 to 10.
- the invention thus provides to blend the newly described here, longer R1 long-chain polyglycol ethers with the foam-suppressing additives from DE-OS 33 15 951.
- Mixing ratios of the two types in the range from 10 to 90 to 90 to 10% by weight, in particular in weight ratios from 60 to 40 to 40 to 60% by weight, are suitable for this embodiment.
- end group-capped polyglycol ethers of the formula (I) which are now to be used according to the invention are also notable for high alkali and acid stability. Their foam-preventing effect in alkaline and neutral cleaning liquors is strengthened in the specified sense, moreover they also meet the legal requirements for biodegradability.
- the cleaning agents in which the end-group-capped polyglycol ethers of the invention are used can contain the constituents customary in such agents, such as wetting agents, builders and complexing agents, alkalis or acids, and corrosion inhibitors and optionally also contain organic solvents.
- Suitable wetting agents are nonionic surface-active compounds such as polyglycol ethers, which are obtained by adding ethylene oxide to alcohols, in particular fatty alcohols, alkylphenols, fatty amines and carboxamides, and anionic wetting agents such as alkali metal, amine and alkylolamine salts of fatty acids, alkylsulfuric acids, alkylsulfonic acids and alkylbenzenesulfonic acids.
- the cleaning agents can, above all, alkali metal orthophosphates, polymer phosphates, silicates, borates, carbonates, polyacrylates and gluconates, as well as citric acid, nitrilotriacetic acid, ethylenediaminetetraacetic acid, 1-hydroxyalkane-1,1-diphosphonic acid and ethylenediphosphonic acid, Contain phosphonoalkane polycarboxylic acids such as phosphonobutane tricarboxylic acid and alkali metal salts of these acids.
- Highly alkaline cleaning agents especially those for bottle cleaning, contain considerable amounts of caustic alkali in the form of sodium and / or potassium hydroxide.
- the cleaning agents can contain organic solvents, for example alcohols, gasoline fractions and chlorinated hydrocarbons as well as free alkylolamines.
- cleaning agents are once understood to mean the aqueous solutions intended for direct application to the substrates to be cleaned, but the term cleaning agents also includes the concentrates and solid mixtures intended for the preparation of the application solutions.
- the ready-to-use solutions can be acidic to strongly alkaline; they are generally used at temperatures of around 20 to 90 ° C.
- the end group-sealed polyglycol ethers to be used according to the invention give effective effects even in low concentrations. They are preferably added to the cleaning agents in amounts such that their concentration in the ready-to-use solutions is approximately in the range from 50 to 500 ppm.
- the foam attenuation of the additives selected according to the invention - and, in comparison, structurally similar additives but not within the scope of the invention - is determined using a test method which is described as follows: 300 ml of a 1% aqueous sodium hydroxide solution are heated to 20 or 65 ° C. in a double-walled 2 l measuring cylinder. The selected foam-suppressing additive is then added in the amounts specified below. With the help of a laboratory hose pump, the liquid is pumped around at a circulation rate of 4 l per minute. The test solution is sucked in approx.
- test foamer a 1% aqueous solution of the triethanolamine salt of tetrapropylene benzene sulfonate
- test foamer 1 ml of a 1% aqueous solution of the triethanolamine salt of tetrapropylene benzene sulfonate
- a foam-suppressing additive A selected according to the invention is used in each case at 20 ° C. and 65 ° C. and its foam-suppressing effect is compared with an additive of the prior art (product B).
