Patent ID: 7927566

Claim:
A method of diluting solutions containing macrocyclic compounds, comprising the step of: providing a solution containing one or more macrocyclic compounds selected from (i) crown ethers having unsubstituted aromatic fragments; (ii) crown ethers having substituted aromatic fragments containing alkyl and/or hydroxyalkyl substituents of a linear and/or ramified structure; (iii) crown ethers having unsubstituted cyclohexane fragments; (iv) crown ethers having substituted cyclohexane fragments containing alkyl and/or hydroxyalkyl substituents of a linear and/or ramified structure; or (v) crown ethers having substituted fragments —O—CHR—CH 2 O—, where R is the normal or ramified alkyl or hydroxyalkyl; and adding a mixture comprising: (1) a polyfluorinated alcohol-telomer 1,1,7-trihydrododecafluoroheptanol-1 of the formula H(CF 2 CF 2 ) 3 CH 2 OH, and (2) a mixture of polyoxyethyleneglycol ethers of synthetic primary higher fatty alcohols of fraction C 12 -C 14 of the general formula C n H 2n+1 O(C 2 H 4 O) 2 H, where n=12 to 14.
