| titleOfInvention | New Crown ether compound and separating agent |
| abstract | A crown ether compound is shown below and useful as a separating agent for chemical compounds.n (In the formula, A and B represent hydrogen atoms, straight chain or branched alkyl groups having 1-6 carbon atoms, allyl groups having 6-10 carbon atoms, or aralkyl groups having 7-9 carbon atoms. Although A and B may be different groups, it is preferable that they be the same. n R₁ represents a hydrogen atom, a straight chain or branched alkyl group having 1-20 carbon atoms, or preferably an alkyl group having 6-16 carbon atoms. R₁ may be bonded to any carbon atom on the cyclical ester group and its number is 1-12, and preferably 1-3. n represents an integer from 3-10, and preferably 4-8, with 5 or 6 being even more preferable. n In addition, R₂ and R₃ represent straight chain or branched alkyl groups having 1-30, and preferably 6-20 carbon atoms, or aryl groups having 6-18 carbon atoms, or aralkyl groups having 7-30 carbon atoms. The location of R₂ and R₃ may be anywhere other than the A and B substitution positions on the condensed ring, and although one of each of R₂ and R₃ is satisfactory, a maximum of 5 groups may be substituted. In addition, R₂ and R₃ may also be different.) |
