Abstract

Liquid multiphase system of two, three (I, II, III) or more immiscible liquids, optionally dyed by the addition of dyes, for use in decorative objects.
The phases are obtained by mixing an aqueous phase with one or more organic phases or ionic liquids.
The density and solution properties of the aqueous phase (I) are adjusted by the addition of very readily water-soluble inorganic or organic salts (sulfates, halides, hydroxides, silicates, bristles, chromates, dichromates, cyanates, thiocyanates, thiosulfates, carbonates, bicarbonates, nitrites, nitrates , Hydrogen sulfates, phosphates, hydrogen phosphates, chlorites, chlorates, perchlorates, sulfites, hydrogen sulfites, dithionates, peroxodisulfates, dithionites, acetates, etc.), by other readily water-soluble compounds (urea, urotropin, sugar, etc.) or by surfactants or emulsifiers.

Description

Liquid multiphase systems are known in the art and can be obtained by contacting immiscible liquids ( DE 4103488 A1 ). For example, a simple two-phase system can be obtained by mixing water with gasoline. The phase separation is due to the difference in polarity and the different densities of gasoline and water, the gasoline phase separates after each mixing over the water phase.

By targeted mixing of liquids with different ones Polarities and viscosities can be systems be generated, which after each mixing process in three phases with the lowest density phase always at the top located. The densities and the miscibility of individual phases can be influenced by the addition of additives. Such additives are For example, emulsifiers, surfactants or salts. By skillful Choice of components are also liquid multi-phase systems conceivable with more than three phases. The addition of elemental mercury would produce a fourth phase in each three-phase system. Such multiphase systems have not been used for decorative purposes used.

Generated By using a multiphase system, each of the phases can be added by adding a dye, depending on its polarity, be selectively colored. This allows extremely aesthetic color arrangements and generate patterns that shake a short time make colorful emulsion. Such colorful multiphase systems can for decorative purposes, for example, in transparent vessels filled (vases, snow globes, lamps, discs, etc.). By adding insoluble, chemically inert solids (Flitter, luminous powder, pebbles, pearls, etc.) can achieved in these systems further optical sophisticated effects become.

One typical three-phase system is obtained by mixing a saturated with potassium carbonate, aqueous Solution with ethanol and a paraffin oil. replaces the ethanolic phase by glycerol, propylene glycol or a Polyetherpha se, we obtain a non-combustible system without volatile components. Replacing potassium carbonate by another suitable harmless salt and the paraffin oil with organic or cooking oil, you do not get one flammable system that does not contain hazardous substances. Such systems can in many areas of daily life be used safely. The addition of rhodamine B (red) or For example, eosin (orange) selectively stains the middle one Phase, surrounded by two colorless liquids is. The shaking of the system briefly generates a intensely colored emulsion, which after a few seconds to returns to its original form within a few minutes.

Claims (8)

Liquid multiphase system of two, three (I, II, III) or more immiscible liquids, optionally colored by the addition of dyes, for use in decorative objects. The phases are obtained by mixing an aqueous phase with one or more organic phases or ionic liquids. The Density and solution properties of the aqueous phase (I) are adjusted by the addition of very good water-soluble inorganic or organic salts (sulphates, halides, hydroxides, Siliates, bristles, chromates, dichromates, cyanates, thiocyanates, thiosulfates, Carbonates, bicarbonates, nitrites, nitrates, hydrogen sulfates, Phosphates, hydrogen phosphates, chlorites, chlorates, perchlorates, sulfites, hydrogen sulfites, Dithionates, peroxodisulfates, dithionites, acetates, etc.), by other good water-soluble compounds (urea, urotropin, Sugar, etc.) or by surfactants or emulsifiers. A phase which is not miscible with the aqueous phase (II) is obtained by adding alcohols (methanol, ethanol, Propanol, ethylene glycol, propylene glycol, glycerine, polyvinyl alcohol etc.), ethers (diethyl ether, tetrahydrofuran, dioxane, polyethylene glycol, Polypropylene glycol, methoxypolyethylene glycol, etc.), ketones or Aldehydes (acetone, methyl ethyl ketone, acetaldehyde, polyvinylpyrrolidone etc.), acids or esters (acetic acid, phosphoric acid, Ethyl acetate, etc.), halogenated hydrocarbons (dichloromethane, Chloroform, carbon tetrachloride, etc.), nitriles (acetonitrile) or other organic solvents and liquids. Another not miscible with the aqueous phase Phase (III) is obtained by adding nonpolar hydrocarbons and hydrocarbon mixtures (pentane, hexane, cyclohexane, heptane, Benzene, toluene, gasoline, diesel, paraffin oil, etc.) or other non-polar compounds (edible oil, biodiesel, fats, etc.). Another not miscible with the aqueous phase Phase (II) can be achieved by adding ionic liquids (Butylmethylimidazolium tetrafluoroborate, ethylmethylimidazolium hexafluorophosphate etc.). Another not miscible with the aqueous phase Phase (II) can be obtained by adding silicone oils (Oligio and polysiloxanes). The optional dyeing of the aqueous Phase (I) is carried out by water-soluble, colored salts or dyes (Copper sulfate, potassium hexacyanoferrate, nickel sulfate, potassium permanganate etc.). Optional dyeing of polar, organic Phase (II) is carried out by polar dyes or inducers (uranin, Rhodamine B, eosin, thymolphthalein, etc.). The optional dyeing of the non-polar hydrocarbon phase (III) is carried out by nonpolar dyes (Sudan III, Sudan B, etc.).
