Assay of sodium and potassium by macrocyclic polyethers (polyoxadiaza macrobicyclic reagents)

Assay of sodium and potassium by macrocyclic polyethers (polyoxadiaza macrobicyclic reagents). Van Poucke, Martine; Resibois, Bernard; Bertrand, Jean (Lab. Chim. Miner. Chim. Anal., Fac. Pharm., Lille, Fr.). Ann. Pharm. Fr., 35(5-6), 205-17 (French) 1977. CODEN: APFRAD. DOCUMENT TYPE: Journal CA Section: 64 (Pharmaceutical Analysis) Various electrodes and polyoxadiaza macrobicyclics were examd. for use in electrochem. detn. of Na and K. KryptoFix 222 (I) [23978-09-8], KryptoFix 221 (II) [31364-42-8], and KryptoFix 211 (III) [31250-06-3] (all 10-3-102 M) were stable in MeOH soln. However, I was unsuitable for K detn. The electrodes sp. for each ion had a sensitivity of 10-5 M. The K or Na levels of various reducing agents, oxidizing agents, and org. compds. were detd.

Orbital levels of crown ethers and related macrocycles studied by ultraviolet photoelectron spectroscopy: relationship to complexation studies

Orbital levels of crown ethers and related macrocycles studied by ultraviolet photoelectron spectroscopy: relationship to complexation studies. Baker, A. David; Armen, G. Horozoglu; Funaro, Stephen (Dep. Chem., City Univ. New York, Flushing, NY 11367, USA). J. Chem. 31364-42-8 and 111-96-6 which are cas registry numbers are also used here. Soc., Dalton Trans., (11), 2519-23 (English) 1983. CODEN: JCDTBI. ISSN: 0300-9246. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) Section cross-reference(s): 28 The valence-shell ionization potentials of several crown ethers and related macrocyclic ligands were measured by UPS. Results were compared with those for corresponding open-chain and other model compds. There is generally appreciable through-bond or through-space interactions between the hetero atom lone pair orbitals, making the macrocycles softer ligands than would otherwise be anticipated. .
