Les fullerènes : préparation et purification par chromatographie liquide préparative

Abstract : Our purpose was the study of the production and the purification of fullerenes. After summarizing the bibliographic advances in the field of fullerenes production, synthesis mechanisms hypotheses and usual analysis methods, we focuse on the parameters which are expected to step in these molecules discovered recently : the simultaneous presence of aromatic molecules and warmth. In the second part of this thesis, we perform laser ablation experiments on various carbonaceous materials and show the link between the aromatic behavior of the target and the nature of fullerenes. We also propose original fullerenes sources, as polystyrene and toluene combustion or fullerenes recovery in carbonaceous wastes of some industrial processes. The production methods of fullerenes and particularly those presented in this work, lead to complex, mixtures of fullerenes and polycyclic aromatic compounds (PAC). We propose solutions for extraction, pre-purification for partial PAC elimination and separation of fullerenes. We develop a convenient method easy to be scaled-up. We present production forecasts and cost of fullerenes preparative scale separation
