      Characterization of some dibenzo crown ethers by RPTLC
      P. KUS, (Dept. of Chem., Silesian Univ., 9 Szkolna Street, 40-006 Katowice, Poland)

      J. Planar Chromatogr. 9, 293-296 (1996). TLC of dibenzo-18-crown-6, 4,5(5')-di-tert-butyldibenzo-18-crown-6, dibenzo-16-crown-5, 4,5(5')-di-tert-butyldibenzo-16-crown-5, dibenzo-14-crown-4, 4,5(5')-di-tert-butyldibenzo-14-crown-4, 4,5(5')-di-tert-butyldibenzo-24-crown-8, and dibenzo-24-crown-8 on RP-2, RP-18, or NH2 with methanol - water, isopropanol - hexane, isopropanol - water in different ratios or acetonitrile. The best separations were observed with mobile phases containing 80-90% methanol. Visualization by exposure to iodine vapor and under UV 254 nm. - Separation on RP-18 confirms the order of hydrophobicity of the investigated crown ethers.
