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].
