Definitions
- the invention relates to the use of selected mixtures of end group-capped polyethylene glycol ethers as foam-pressing additives in low-foam cleaning agents.
- the invention is intended to provide auxiliaries of the type mentioned, which combine high effectiveness with physiological harmlessness and biodegradability.
- the invention is also based on the object of on the one hand enabling the performance profile of the auxiliaries used to be optimized in practical use, but on the other hand providing selected polyethylene glycol ethers of the type mentioned which ensures improved formulation of these auxiliaries in commercially available concentrate form. This last-mentioned aspect has considerable practical significance and can be understood from the following:
- Low-foaming cleaning agents for use in trade and industry, in particular for cleaning metal, glass and ceramic surfaces generally contain foam-suppressing additives which are able to counteract undesirable foam development.
- This use of the foam-pressing aids is usually due to the fact that the contaminants detached from the substrates and accumulating in the cleaning baths act as foaming agents.
- the cleaning agents themselves can also contain constituents which give rise to undesirable foam formation under the given working conditions.
- anionic surfactants are also used anionic surfactants.
- aqueous acid concentrates and in particular corresponding concentrates of aqueous phosphoric acid play a considerable role as a mixture component of the overall system in industrial cleaning.
- DE-OS 38 00 493 (D 81 13) describes the use of polyethylene glycol ethers of the general formula (I) given above, but now in this formula R a straight-chain or branched alkyl or alkenyl radical with 20 to 28 carbon atoms, R. is an alkyl radical with 4 to 8 carbon atoms and n is a number from 6 to 20.
- R a straight-chain or branched alkyl or alkenyl radical with 20 to 28 carbon atoms
- R. is an alkyl radical with 4 to 8 carbon atoms
- n is a number from 6 to 20.
- the decisive modification here is the use of longer-chain residues R-.
- These end group-sealed polyglycol ethers are also notable for high alkali and acid stability. Its foam-preventing effect in alkaline and neutral cleaning liquors is enhanced in the specified sense, moreover they also meet the legal requirements for biodegradability.
- the teaching of the present invention is based on the finding that the task of optimizing, on the one hand, the performance profile and, on the other hand, the formulability of the polyethylene glycol ether of the general formula (I) mentioned in the commercial concentrate form becomes possible if selected mixtures of polyethylene glycol ethers of the general formula (I) can be used.
- the invention accordingly relates to the use of such selected polyethylene glycol ether mixtures which have the general formula (1)
- R-O-C CH-CH-O) -R_ (I) 1 2 2 n 2 are sufficient, where R. each has a long-chain branched alkyl and / or alkenyl radical, R_ an alkyl radical with 4 to 8 carbon atoms and n one Numbers of at least 4 mean as foam-suppressing additives for low-foam cleaning agents.
- the teaching according to the invention is characterized in that mixtures of those polyethylene glycol ethers are used in which the R.O- radical is derived from the alcohol mixtures (a) or (b) given below: a) 10 to 100 M ⁇ r% of an equimolar mixture of isomers 2-hexyldodecanol-1 and 2-octyldecano! -1
- n each means a number from 5 to 9.
- substance mixtures of the type defined according to the invention with the heavy weight of the C number distribution in the rest R-0- from the general formula in the range from about 16 to 18 C atoms are particularly valuable if branched alkanols of the Guerbet alcohol type form the basic substance here.
- Alcohols of this type are known to be formed by the condensation of fatty alcohols with a lower carbon number in the presence of alkali i, e.g. B. 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 have branching in the 2-position to the hydroxyl group.
- the invention will predominantly or preferably exclusively use straight-chain fatty alcohols for the production of the 2-branched Guerbet alcohols and ultimately for the synthesis of the compounds of the general formula (I).
- Fatty alcohol oils of natural origin are known to have at least largely predominantly even chain lengths, so that their 2-branched Guerbet alcohol with 18 C atoms cannot be obtained as a uniform condensation product of only a selected fatty alcohol via their dimerization.
- 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: 5 to 1: 9 and the hydroxyl groups present in the reaction product obtained are then etherified.
- 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 straight-chain or branched C 1 -C 4 -alkyl halides.
- n-butyl radical for the radical R 2 from the general formula (I).
- examples of such a final etherification are accordingly n-butyl halides such as n-butyl chloride.
- the invention is not limited to this. Further examples are amyl halides, hexyl halides and the higher alkyl halides in the range mentioned.
- alkyl halide and alkali in a stoichiometric excess, for example from 10 to 50, over the hydroxyl groups to be etherified.
- the cleaning agents in which the end group-capped polyglycol ether mixtures of the invention are used can contain the constituents customary in such agents, such as wetting agents, builder substances and complexing agents, alkalis or acids, Corrosion inhibitors and optionally also contain organic solvents.
- the surfactants used are nonionic surface-active compounds of the polyglycol ether type which are obtained by the addition of ethylene oxide to alcohols, in particular fatty alcohols, alkylphenols, fatty amines and carboxamides, and anionic surfactants such as alkali metal, amine and alkylolamine salts of fatty acids, alkylsulfuric acids, alkylsulfonic acids and alkylbenzenesulfonic acids into consideration.
- the scaffolding substances and complexing agents can
- Detergents especially alkali metal orthophosphates
- aqueous phosphoric acid concentrates which contain approximately equal amounts of phosphoric acid and water can be mixed with the mixtures of the formula (I) according to the invention to give concentrates which are single-phase in the temperature range from 0 to 50 ° C. and are therefore particularly suitable for simple practical use own.
- the combination of this property with the broad applicability of such substance mixtures as additional components with foam-suppressing action both at low temperatures (20 C) and at elevated temperatures (65 C) represents a significant enrichment of the technical possibilities of the subject area given here.
- end group-sealed polyglycol ether mixtures 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 defoaming effect is tested under the following conditions: 300 ml of a 1% strength by weight aqueous sodium hydroxide solution are heated to 20 ° C. or 65 ° C. in a double-walled 2 liter measuring cylinder. 0.1 ml of the defoaming surfactant to be determined is added to this solution. With the help of a peristaltic pump, the liquid is circulated at a rate of 4 l / min. pumped around. The test liquor is approx.
- a 1% by weight aqueous solution of the triethanolamine salt of tetrapropylene benzene sulfonate is used as the test foam. This is done every 1 minute in quantities of 1 m! added to the fleet in circulation. The resulting total volume of foam and liquid is determined.
- the foam-inhibiting effect of the surfactant material used in each case is all the better the longer the period of time required to reach the 2000 ml mark in the measuring cylinder due to the total volume of the liquid and foam phases.
- the respective are corresponding Numerical values for this time are given in minutes or in ml of test foam.
- Formulation test recipe 1 (according to the invention) 40% phosphoric acid (85%)
- the formulation is single-phase in the temperature range from 0 ° C. to 50 ° C. and shows no separation whatsoever.
- the recipe separates above 30 ° C in 2 phases and is therefore not usable in practice.
- the formulation is single-phase in the temperature range from 0 ° C. to 50 ° C. and shows no separation whatsoever.
