The Uses of 2-(HYDROXYMETHYL)-12-CROWN 4-ETHER
2-Hydroxymethyl-12-crown-4 can be used:
- To prepare an ester of lasalocid with crown ether to study its complex formation with monovalent cations.
- To prepare hydrogel adsorbents for potential usage in the recovery of lithium-ions from seawater.
- As a starting material in the synthesis of metal-free phthalocyanines and metallophthalocyanines.
Purification Methods
Purify it by chromatography on Al2O3 with EtOAc as eluent to give a hygroscopic colourless oil, which is distilled under high vacuum and is distilled in vacuo. It has IR: 3418 (OH) and 1103 (COC) cm-1, NMR: max 3.70s. [Kimura et al. J Chem Soc, Chem Commun 492 1983, Pugia et al. J Org Chem 52 2617 1987.] S -(-)-5-Hydroxymethyl -2(5 H )-furanone [78508-96 -0] M 114.1, 39 -42o, 40 -44o , b 1 3 0o/0.3mm, [ ] 546 -180o, [ ] D -148o (c 1.4, H2O). It is purified by chromatography on Silica gel using hexane/EtOAc (1:1) to give a colourless oil which is distilled using a Kügelrohr apparatus, and the distillate crystallises on cooling. It has RF 0.51 on Whatman No 1 paper using pentan-1-ol and 85% formic acid (1:1) and developing with ammoniacal AgNO3. [Boll Acta Chem Scand 22 3245 1968, NMR: Oppolzer et al.
