Abstract

The invention relates to an improved method for chemically cleaning textile, leather, or fur goods, wherein the goods to be cleaned are brought into contact with a cleaning agent, wherein the cleaning agent comprises at least one solvent, wherein according to the invention a cleaning agent is used comprising a compound of the general formula (I) as a solvent, wherein x is a whole number from 1 to 10 and R¹, R², R³, and R⁴ are selected independently of each other from H, a C₁- to C₂₂-alkyl radical or alkenyl radical, a polyalkylene oxide, a C₃- to C₆-cycloalkyl radical, a carbo- or heterocyclical C₃- to C₆-cycloalkenyl radical, and an aryl radical. The invention further relates to the use of a solvent having the general formula (I) for producing a cleaning agent for chemically cleaning textiles, leather, and fur goods, and a liquid cleaning agent for use in a method for chemically cleaning textile, leather, or fur goods, wherein the cleaning agent comprises a portion of a solvent having the general formula (I).

Claims

1. A use of a solvent of the general formula (I):

2. A use as set forth in claim 1 wherein R² and R⁴ can be selected independently from each other from an ethyl, n-propyl, iso-propyl, n-butyl, iso-butyl, secondary butyl, tertiary butyl, n-pentyl, iso-pentyl, neopentyl, cyclopentyl, n-hexyl, iso-hexyl, cyclohexyl, octyl, iso-octyl, 2-ethylhexyl, n-decyl, isotridecyl, phenyl, benzyl, phenylethyl and nonylphenyl residue.

3. A use as set forth in claim 1 wherein

x is a whole number of between 1 and 5,

R¹ and R³ are H and

R² and R⁴ are selected independently of each other from an unsubstituted or substituted, straight-chain or branched C₂- through C₈-n-alkyl or C₂- through C₈-iso-alkyl residue.

4. A use as set forth in claim 1 wherein substituted R¹, R², R³, R⁴, if present, are substituted with one or more from −

Cl, —

Br, —

I, —

7. A use as set forth in claim 1 wherein the cleaning agent also has a proportion of a cleaning booster or a cleaning booster is meteredly added to the cleaning agent during the method or the article to be cleaned is also brought into contact with a cleaning booster during the method.

8. A use as set forth in claim 1 wherein the cleaning agent additionally includes a substance suitable for chemical cleaning agents for trapping hydrogen proton donors, free hydrogen protons and/or free carbonyl compounds.

9. A use as set forth in claim 1 wherein the cleaning agent also has a proportion of another solvent which is suitable for the cleaning of textile, leather or fur goods and which is different from the solvent of the formula (I) or another solvent which is suitable for the cleaning of textile, leather or fur goods and which is different from the solvent of the formula (I) is meteredly added to the cleaning agent during the method or the article to be cleaned is also brought into contact with another solvent which is suitable for the cleaning of textile, leather or fur goods and which is different from the solvent of the formula (I) during the method.

10. A use of a solvent of the general formula (I) or the special formula (III) and having the features as set forth in claim 1 for the production of a cleaning agent for the chemical cleaning of textile, leather and fur goods, wherein the cleaning agent has a proportion of a solvent of the general formula (I) or the special formula (III) and a proportion of a cleaning booster and/or a proportion of a substance suitable for chemical cleaning agents for trapping hydrogen proton donors, free hydrogen protons and/or free carbonyl compounds and/or a proportion of another solvent which is suitable for the cleaning of textile, leather or fur goods and which is different from the solvent of the formula (I).

11. A liquid cleaning agent for use in a method of chemically cleaning textile, leather or fur goods, wherein the cleaning agent has a proportion of a solvent of the general formula (I) or the special formula (III) and having the features as set forth in claim 1 and a proportion of a cleaning booster and/or a proportion of a substance suitable for chemical cleaning agents for trapping hydrogen proton donors, free hydrogen protons and/or free carbonyl compounds and/or a proportion of another solvent which is suitable for the cleaning of textile, leather or fur goods and which is different from the solvent of the formula (I).

12. A use as set forth in claim 10 wherein the cleaning booster is selected from anionic surfactants, cationic surfactants, non-ionic surfactants, amphoteric surfactants, microbicides, preserving agents, feel improvers, finishes, fragrance substances, water, preserving agents, odor absorbers, anti-static components, dissolving intermediaries, corrosion inhibitors, deodorants, emulsifiers, finishing agents, fluorocarbon resins or combinations thereof.

13. A use as set forth in claim 10 wherein the other solvent which is suitable for the cleaning of textile, leather or fur goods and which is different from the solvent of the formula (I) is selected from perchloroethylene, aromatic hydrocarbons, light benzenes, Stoddard solvent, white spirit, chlorohydrocarbons (CHC), fluorochlorohydrocarbons (FCHC), isoparaffins (HBS) and cyclosiloxane D5 (decamethylcyclopentasiloxane) and combinations thereof.

14. A cleaning agent as set forth in claim 11 wherein the cleaning booster is selected from anionic surfactants, cationic surfactants, non-ionic surfactants, amphoteric surfactants, microbicides, preserving agents, feel improvers, finishes, fragrance substances, water, preserving agents, odor absorbers, anti-static components, dissolving intermediaries, corrosion inhibitors, deodorants, emulsifiers, finishing agents, fluorocarbon resins or combinations thereof.

15. A cleaning agent as set forth in claim 11 wherein the other solvent which is suitable for the cleaning of textile, leather or fur goods and which is different from the solvent of the formula (I) is selected from perchloroethylene, aromatic hydrocarbons, light benzenes, Stoddard solvent, white spirit, chlorohydrocarbons (CHC), fluorochlorohydrocarbons (FCHC), isoparaffins (HBS) and cyclosiloxane D5 (decamethylcyclopentasiloxane) and combinations thereof.
