Definitions

the invention relates to a method for the filtration of organic solvent-containing liquors in dry cleaning. It also concerns filter aids used in the filtration of these fleets.
the invention has for its object to largely free the solvents or solvent mixtures used in dry cleaning by improved filtration of dissolved contaminants, odors and dyes, pre-detergent and cleaning enhancers, so that distillation of the solvent is only necessary at large intervals.
the invention also relates to filter aids for use in the filtration of cleaning liquors from dry cleaning, which are characterized in that they are prepared with ammonium compounds of the above general formula (I) in an amount of 2 to 60% by weight of natural and / or synthetic layered silicates in combination with diatomaceous earth and / or activated carbon.
silicate materials of natural and / or synthetic origin are suitable as layer silicates.
mica-like sheet silicates with a three-layer structure from the group of the smectites are used, but vermiculite and the sodium phyllosilicates, which belong to the non-mica-like sheet silicates, are also suitable.
vermiculite and the sodium phyllosilicates which belong to the non-mica-like sheet silicates, are also suitable.
To the smectites include montmorillonite, saponite, beidellite and hectorite; Examples of phyllosilicates are kenyaite, magadiite, makatite and kanemite.
Bentonites with a high content of montmorillonite or hectorite are preferably used, natural bentonites being used in untreated form or, if appropriate, in a form which has been pretreated with acids or alkalis for cleaning and removing disruptive cations in a manner known per se.
the most important parameter of the layered silicate materials that can be used is their exchange capacity for cations. According to the invention, this size should not be less than 30 meq / 100 g of layered silicate. Those smectite clay minerals whose cation exchange capacity is between 50 and 120 meq / 100 g layered silicate are particularly preferred.
Natural and / or synthetic layered silicates with the properties mentioned are prepared according to methods known per se with one or more long-chain ammonium compounds of the above-mentioned general formula (I) in an amount of up to 60% by weight, based on the total weight of the modified layered silicate . This can for example be done by treating the respective silicates with solutions of the desired ammonium compounds and thus an exchange of Al - kalimetall cations of the layered silicates to the ammonium cations achieved.
the layered silicates are preferably prepared with amounts of ammonium compounds in the range from 5 to 30% by weight, particularly preferably in the range from 10 to 25% by weight.
the quaternary ammonium compounds are particularly preferred; that is, compounds in which none of the radicals R to R are hydrogen.
the anion X - stands for anions of water-soluble acids with a dissociation constant above 10 -5 , preferably for chloride, bromide, acetate, hydrogen sulfate or hydrogen phosphate, but especially for chloride.
Lauryltrimethylammonium chloride and distearyldimethylammonium chloride have proven particularly useful for the preparation of natural and / or synthetic layered silicates.
other quaternary ammonium salts containing, for example, aromatic radicals R can also be used with advantage, such as, for example, cetyldimethylbenzylammonium chloride.
Laurylpyridinium chloride is mentioned as an example of quaternary ammonium salts of the general formula (I), in which the organic radicals R, including the nitrogen atom, can be closed to form a heterocyclic ring system.
the natural and / or synthetic layered silicates prepared with the ammonium compounds mentioned are used for the process according to the invention as feed for precoat or cartridge filters, with cartridge filters being particularly preferred will.
the feed can either consist exclusively of the prepared layered silicates mentioned or, preferably, contain admixtures of conventional further filter aids, for example diatomaceous earth and / or activated carbon. If mixtures of diatomaceous earth / layered silicate or activated carbon / layered silicate are used, the mixing ratio of the components mentioned is 80:20 to 50:50, particularly preferably 70:30 to 50:50.
the filter aids described are much more suitable for use in the process according to the invention for the filtration of liquors containing organic solvents in chemical cleaning than conventional adsorption filters which contain kieselguhr, activated carbon, zeolites or mixtures of these materials.
the use of the filter aids mentioned has great advantages, in particular if trichlorethylene, 1,1,1-trichloroethane, perchlorethylene, monofluorotrichloromethane, trifluorotrichloroethane or mixtures of the solvents mentioned are present as contaminated solvents in the cleaning liquors.
the cleaning liquors can be almost completely freed of loosened dirt, odors and dyes, pre-detachment agents and cleaning boosters.
the distillation of the solvents which is often required by conventional filtration processes, is only much less necessary. This not only saves solvents, but also significantly reduces energy costs.
the filter aids which consist of a mixture of layered silicate with diatomaceous earth or activated carbon, are always characterized by particularly universal cleaning properties.
the cleaning booster was dissolved in an amount of 7 g per liter of cleaning liquor.
the filter aid is a mixture of 60% granular activated carbon (particle diameter 1.5. Mm) and
the layered silicate was a hectorite which was loaded with 27% by weight of lauryltrimethylammonium chloride.
Example 1 The cleaning liquor described in Example 1 was pumped in circulation through a cartridge filter
Example 1 As a comparison of Example 1 and Comparative Example 1 shows, the fatty acid content and the solids content of the cleaning liquor could be greatly reduced when using the loaded sheet silicate, the cleaning booster could even be completely removed from the fleet.
the unloaded layered silicate showed worse results in all three cases.
Example 2 shows that the filtration with the prepared layered silicate led to significantly better filtration results; the amount of dissolved impurities was only a fraction of the impurities after filtration with unprepared layered silicate.
the cleaning liquor mainly contained perchlorethylene as the organic solvent component.
Example 3 Under the conditions described in Example 3, a precoat filter was used, which was charged with 70 g of diatomaceous earth and 30 g of powdered activated carbon. The results are shown in Table 1.
a cleaning test liquor was prepared which contained trichlorethylene as the organic solvent, to which 10 g of tallow fatty acid per liter of organic solvent had been added.
the solvent was also colored strongly red by peeling off a textile naphthol color. It was pumped in circulation for two hours through a filter which was charged exclusively with a hectorite which contained lauryltrimethylammonium chloride as a quaternary ammonium compound in an amount of 5% by weight. After the filtration, samples were taken from the test liquor and examined for their fatty acid content and their color behavior. The results are shown in Table 3 below.
