Abstract
The thermal properties and gas Chromatographie behaviour of manganese(II) and manganese(III) trifluoroacetylacetonates (TFA) were investigated by using the ligand vapour technique. The two chelates, Mn(TFA); and Mn(TFA)3, can be quantitatively eluted on a mixed-liquid phase (1.9% OV-17 ÷ 0.1% PEG-20M) at column temperatures above 210°C and 130–150°C, respectively; Mn(TFA)3 is completely converted to Mn(TFA)2 by thermal dissociation at column temperatures above 180°C and completely eluted as Mn(TFA)2 above 210°C. The chelates can be determined separately within errors of about 1% after a preliminary extraction.
