4,13-Diaza-18-crown 6-ether Chemical Properties,Usage,Production

Chemical Properties

off-white shiny crystalline powder

Uses

1,4,10,13-Tetraoxa-7,16-diazacyclooctadecane is a crown ether, which can be used:

  • In the spectroscopic studies of its complex-forming reaction with iodine.
  • To prepare the ligand 7,16-bis(5-t-butyl-2-hydroxybenzyl)-1,4,10,13-tetraoxa-7,16-diazacyclooctadecane.
  • As a ligand in the study of zirconium facilitated hydrolysis of a dipeptide at neutral pH.

Purification Methods

Twice recrystallise it from *benzene/n-heptane, and dry it for 24hours under high vacuum [Weber & V.gtle Top Curr Chem (Springer Verlag, Berlin) 98 1 1981, D'Aprano & Sesta J Phys Chem 91 2415 1987].
