     where
 A is (CH 2 ) a  or phenylene, 
 R 1 , R 2 , R 3  and R 4  identically or independently denote C 1  to C 22 -normal or C 1  to C 22 -iso-alkyl or mixtures of C 1  to C 22 -normal and C 1  to C 22 - iso-alkyl, C 5 -cycloalkyl or C 6 -cycloalkyl, phenyl-C 1 -C 4 -alkyl, C 1 -C 8 -alkylphenyl or phenyl, 
 and a is an integer from 0 to 6. 
 
   
   
       2 . The process according to  claim 1  wherein R 1 , R 2 , R 3  and R 4  identically or independently denote C 1  to C 13 -normal alkyl or C 1  to C 13 - iso-alkyl or mixtures of C 1  to C 13  normal-alkyl and iso-alkyl, C 5 -cycloalkyl or C 6 -cycloalkyl, phenyl-C 1 -C 2 -alkyl, C 1 -C 9 -alkylphenyl or phenyl and a denotes an integer from 0 to 2. 
   
   
       3 . The process according to  claim 1  wherein the textile material is treated with a compound of the formula (1) where R 1 , R 2 , R 3  and R 4  identically or independently denote C 1  to C 8 -normal or C 1  to C 8 -iso-alkyl or mixtures of C 1  to C 8 -normal C 1  to C 8 -iso-alkyl, cyclohexyl, benzyl or phenyl and a denotes 0 or 1. 
   
   
       4 . The process according to  claim 1  wherein the textile material is treated with a compound of the formula (1) where R 1 , R 2 , R 3  and R 4  identically or independently denote C 1  to C 3 -normal C 1  to C 8 -iso-alkyl or mixtures of C 1  to C 8 -normal and C 1  to C 8 -iso-alkyl and a denotes 0. 
   
   
       5 . (canceled) 
   
   
       6 . The process according to  claim 1  wherein the compound of the formula (1) is a constituent of a spotting agent, of a cleaning booster or of a cleaning activator. 
   
   
       7 . The process according to  claim 1  wherein the compound of the formula (1) is in combination with other components selected from the group consisting of anionic surfactants, nonionic surfactants, amphoteric surfactants, cationic surfactants, odor absorbents, deodorants, scents, antistats, microbicides, preservatives, solubilizers, fiber regenerants, finishes, emulsifiers, enzymes, impregnants and water in small amounts. 
   
   
       8 . The process according to  claim 1  wherein R 1 , R 2 , R 3  and R 4  denote methyl or ethyl or a mixture of methyl and ethyl and a denotes 0. 
   
   
       9 . The process according to  claim 1  wherein the process for dry cleaning of textiles is performed in the industrial and institutional sector. 
   
   
       10 . The process according to  claim 1  wherein the process for dry cleaning of textiles is performed in the home. 
   
   
       11 . The process according to  claim 1  where R 1 , R 2 , R 3  and R 4  contain different numbers of carbon atoms. 
   
   
       12 . The process according to  claim 1  wherein the textile material is treated with two or more compounds of formula  1  which each of said compounds of formula 1 differ in the number of carbon atoms they contain. 
   
   
       13 . The process of  claim 1 , wherein the textile material is treated with the compound of formula (1) in combination with chloroethylene or a hydrocarbon or a mixture of chloroethylene and a hydrocarbon.
