    The Investigation of Alunite Mud Waste of Aluminium Industry From Chemical and Ecological Point of View
    (1996) Hacızade, F.; Uçan, H. I.
    The alunite mud waste of, aluminium industry and its properties have been investigated from chemical and ecological point of view. The special mixture obtained from CaO-H2O -NaCl system was proposed for prevention of dusting and environmental pollution in terms of the wasting material properties. The chemical and x-ray analysis of alunite ore and the resulting alunite mud waste were done and their compositional differences were identified. The dusting properties of tue waste material was found to be excessive and caused environmental pollution. In this study, some suggestions were made for prevention of pollution.

    The Synthesis of Four New Schiff Bases and Some of Their Transition Metal Complexes
    (MARCEL DEKKER INC, 1998) Uçan, H. I.; Karataş, I.; Irez, G.; Deveci, M. A.; Mercimek, B.
    Isonitrosoacetophenone, synthesized by nitrosotion of acetophenone, has been condensed with diamines (1,4-phenylenediamine, 4,4'-diaminobiphenyl, 4,4'-diaminodiphenylmethane or 4,4'-diaminodiphenylether) to obtain the tetradentate Schiff bases 1,4-phenyliminobis(isonitrosoacetophenone), 1,1'-biphenyl-4,4'-diiminobis(isonitrosoacetophenone), 1,1'-diphenylmethane-4,4'-diiminobis(isonitrosoacetophenone) or 1,1'-diphenyloxy-4,4'-diiminobis(isonitrosoacetophenone). The polymeric Ni(II) and Cu(II) complexes of these Schiff bases are square-planar while the polymeric Co(II) complexes are octahedral with water molecules at the axial positions. The structures of the above complexes were determined by H-1 NMR and IR spectroscopy and elemental analyses.
