Zum chemischen Transport von Bismutoxidhalogeniden BiOX (X = Cl,Br, I) mit Halogen,Halogenwasserstoff sowie Wasser und Bestimmung der Molwärmen von BiOX

Chemical Transport of Bismuth Oxide Halides BiOX (X = Cl, Br, I) with X₂, HX and H₂O, and Determination of the Molar Enthalpies of BiOX By comparison of calculated and experimental chemical transport behaviour of BiOX (X = Cl, Br, I) with X₂, HX, and H₂O it was shown, that we understand the transport of BiOCl, BiOBr and BiOI with X₂ and HX in terms of the well known gaseous spezies in the systems. The existence of gaseous complexes Bi(OH)₂X is be concluded from high transport rates of BiOX with water, and their enthalpies and entropies were derived. The molar enthalpies and standard entropies of BiOX were determined by low temperature C_p measurements. (Data see Inhaltsübersicht)
