A method of mechano-chemical fluorination is described that has a significantly improved yield over prior art methods of synthesis. The present invention illustrates this improved mechano-chemical Fluorination by describing the improved synthesis of Fullerene Fluorides (FF). This method overcomes reduced product yield that results from vibromill (1) material corrosion. This method also overcomes the prior fluorination and FF synthesis problems of the prior art by utilizing different fluorinating materials, adding catalysts and diluting agents to the process, varying milling times, and heating in the presence of inert gasses to improve the fluorination process.
La présente invention concerne un procédé de fluorination mécanochimique procurant un rendement nettement amélioré par rapport aux procédés de synthèse existants. La présente invention propose un procédé de fluorination mécanochimique amélioré pour la synthèse perfectionnée de fluorures de fullerène (FF). Ledit procédé élimine le rendement réduit découlant de la corrosion du matériau de vibro-moulin. Ledit procédé élimine également les problèmes connus liés à la fluorination et la synthèse des FF de l'art antérieur par l'utilisation de différentes matières de fluorination, par l'ajout de catalyseurs et de diluants au procédé, la variation du temps de broyage, et le réchauffement en présence de gaz inertes afin d'améliorer le procédé de fluorination.
