    Notes: The reactions of chloro(dimethyl sulfide)gold(I) with equivalent quantities of the ketiminophosphane diphenyl(diphenylmethyleneamino)phosphane (1a) or its sulfide (1aS) lead to high yields of stable, crystalline 1 : 1 complexes with AuCl units attached to the phosphorus and sulfur atom, respectively. Tris(diphenylmethyleneamino)phosphane (1c) gives the related complex (Ph2C=N)3PAuCl with the gold atom also selectively P-bound. Bis(diphenylmethyleneamino)phenyl-phosphane (1b) could not be used because of its limited stability. Single-crystal X-ray diffraction studies have shown that there is no auxiliary coordination of the metal center by the imino functions of the ligands. The geometry of the P/S—Au—Cl moieties deviates only very slightly from linearity. The angle at the sulfur atom in (Ph2C=N)Ph2PSAuCl is very small [94.30(3)°], but despite of the resulting rather open coordination there are no discernible intra- or intermolecular contacts in the lattice. Such contacts are also absent with (Ph2C=N)Ph2PAuCl and (Ph2C=N)3PAuCl owing to the bulk of the ligands. The 1 : 1 complexes do not react with an excess of (Me2S)AuCl. This finding, and the molecular structures of the 1 : 1 complexes, show very consistently that both phosphane and sulfide donors are far superior as ligands for gold(I) as compared to ketimine donor molecules.

    Notes: Design criteria for extraction with chemical reaction and liquid membrane permeation. Design criteria for extraction and liquid membrane permeation are discussed and related to these classical extraction columns. Well known models, like the diffusion and the forward mixing model, are used to describe the concentration profile in a column. Mass transfer models for a single globule, like the two-layer and the shrinking core model, are incorporated. The complex chemical interactions on an interface are formulated. A final discussion considers the relevance of the model parameters and their influence on mass transfer.

    Notes: Chemical reaction and mass transfer in liquid/liquid systems. In systems with mass transfer and chemical reaction, one has to consider the solubility of the solute in the receiving phase. Modelling of the phenomena will be according to gas/liquid systems for soluble solutes and according to gas/solid systems for insoluble solutes. Criterion for a further lay-out of a contact apparatus is either the Hatta- or the second Damköhler number. This will be demonstrated for the extraction of copper as an example for a countercurrent cascade of mixers and countercurrent columns.

    Inorganic geochemistry of sedimentary rocks in the catchment of river Thuringian Saale during the last 600 Ma (2021)
    PANGAEA
    Details
    Publication Date: 2024-06-25
    Description: A literature retrieval was performed for whole rock geochemical analyses of sedimentary, magmatic and metamorphic rocks in the catchment of River Thuringian Saale for the past 600 Ma. Considering availability and coincidence with paleontological an facies data the following indicators seem suitable to detect environmental and climatic changes: biogenic P for Paleoproductivity, STI Index for weathering intensity, Ni/Co-ratio for redox conditions, relative enrichments of Co, Ba and Rb versus crustal values for volcanic activity at varying differentiation. The Mg/Ca-ratio as proxy for salinity is applicable in evaporites. The binary plot Nb/Y versus Zr/TiO2 indicates a presently eroded volcanic level of the Bohemian Massif as catchment area for the Middle Bunter, whereas higly differentiated volcanics provided source material for Neoproterozoic greywackes. A positive Eu-anomaly is limited to the Lower Bunter and implies mafic source rocks perhaps formerly located in the Bohemian Massif.
