1,4,10,13-TETRAOXA-7,16-DIAZACYCLOOCTADECANE Usage And Synthesis

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].
