Benzo-18-crown-6 Usage And Synthesis

Chemical Properties

white granular powder and chunks

Purification Methods

Purify it by passage through a DEAE cellulose column in cyclohexane. It recrystallises from n-hexane. Its thiourea complex has m 127o [5-6 mol of urea to ether, Pedersen J Org Chem 36 1690 1971]. The stability constants of the Na+, K+, Rb+, Cs+, Tl+ and Ba2+ complexes are described in Hofmanova et al. Inorg Chim Acta 28 73 1978. [NMR: Live & Chan J Am Chem Soc 98 3769 1976]. [Beilstein 19/12 V 618.] IRRITANT.
