Gas-chromatographic behavior of rare earth dipivaloylmethanates and acetylacetonates: Gas-chromatographic behavior of rare earth dipivaloylmethanates and acetylacetonates. Magazeeva, N. V.Several substances are used for example 15492-45-2 and 14284-98-1 which are their cas registry numbers.; Martynenko, L. I.; Murav'eva, I. A.; Sokolov, D. N.; Spitsyn, V. I. (Mosk. Gos. Univ., Moscow, USSR). Izv. Akad. Nauk SSSR, Ser. Khim., (8), 1813-17 (Russian) 1986. CODEN: IASKA6. ISSN: 0002-3353. DOCUMENT TYPE: Journal CA Section: 79 (Inorganic Analytical Chemistry) Section cross-reference(s): 66 The errors assocd. with the sorption of the title complexes during gas chromatog. on columns packed with Inerton coated with 10% Apiezon L were studied. The sorption of dipivaloylmethane complexes is substantially smaller than the sorption of acetylacetonates. The sorption occurs primarily in the liq. phase. The complex is sorbed as a cationic bis(b-diketonate) accompanied by the liberation of an equiv. amt. of the free protonated ligand. .

Applications of the double sphere coordination point charge field [DSPF] model in rare earth complexes: Applications of the double sphere coordination point charge field [DSPF] model in rare earth complexes. (I). Electronic spectrum of ytterbium(III) chelate. Yang, Pin; Li, Huiying (Dep. Chem., Shanxi Univ., Taiyuan, Peop. Rep.In this article, certain chemicals are used.
