Resumen

The presence of small amounts of iron (&gt;0.013% Fe) in sand creates problems in the manufacture of high quality glass. Removal by hot sulphuric acid is possible, but creates environmental problems, and is costly. Hence organic acids such as oxalic have been investigated since they are effective in removing iron, and can be degraded anaerobically. The aim of this work was to identify key intermediates in the anaerobic degradation of oxalate in an upflow anaerobic sludge blanket reactor (UASB) which was removing iron from solution in the sulphide form, and to determine the bacterial specie

Resumen

The latest world malaria report revealed that human deaths caused by malaria are currently on the rise and presently stood at over 627,000 per year. In addition, more than 240 million people have the infection at any given time. These figures make malaria the topmost infectious disease and reiterate the need for continuous efforts for the development of novel chemotherapies. Malaria is an infectious disease caused majorly by the protozoan intracellular parasite Plasmodium falciparum and transmitted by mosquitoes. Reports abound on the central role of falcipains (cysteine protease enzymes) in t

Resumen

Ces travaux de thèse portent sur la synthèse de polyuréthanes par génération in situ d’isocyanates, à travers différentes voies de moindre toxicité que la voie classique faisant appel à l’utilisation directe d’isocyanates. Dans un premier temps, la décarboxylation oxydante des acides oxamiques conduisant à la formation d’isocyanates a été réalisée par activation thermique grâce à l’utilisation d’un iodure hypervalent, jouant le rôle d’oxydant. Une étude cinétique sur des réactions modèles en présence d’alcool, associé à une modélisation numérique, ont notamment mis en évidence un effet catalyt

Resumen

Ce manuscrit présente un nouveau procédé de synthèse d’acides oxamiques aromatiques et leur utilisation en tant que précurseurs de radicaux carbamoyles, pour promouvoir une chimie plus verte et plus sûre des isocyanates. La première étape de ce procédé consiste en une réaction de couplage croisé d’Ullmann-Goldberg entre un iodure d’aryle et un oxamate primaire. Son optimisation a mis en évidence l’influence significative du substituant de l’oxamate sur le rendement de la réaction, et différents modes de désactivation du catalyseur. Un grand nombre d’oxamates aromatiques ont ainsi été synthétis

Resumen

碩士<br>中原大學<br>化學研究所<br>91<br>ABSTRACT This thesis discusses the supramolecular chemistry of silver (Ⅰ) complexes containing polydentate nitrogeneous ligands. A series of silver (Ⅰ) complexes of the types {[Ag2(H2DpyO)2(pyOa)](BF4)} �V, 1 , {[Ag2(H2DpyO)2(pyOa)](ClO4)} �V, 2 , {[Ag2(H2DpyO)2(pyOa)](PF6)} �V, 3 and {[Ag2(H2DpyO)2(pyOa)(NO3)]} �V, 4 , have been prepared by reaction of AgX ( X = BF4-, ClO4-, PF6-, NO3-) with H2DpyO ( H2DpyO = N,N'-di(2-pyridyl)oxamide ) in EtOH / H2O , where pyOa is anion of N-pyridin-2-yl-oxalamic acid . The H2DpyO ligand in 1~4 are coordinated to the silver (Ⅰ)
