专利号:US-2010016607-A1 优先权日:2006-12-11 标题:Process for the Synthesis of Highly Active Binary Metal Fluoride as a Fluorinating Agent for Aromatics 发明人:DOLBIER JR WILLIAM R; JANMANCHI KRISHNA MURTHY 权利人:UNIV FLORIDA 摘要:The subject invention relates to a process for the synthesis of highly active binary metal fluoride system for the fluorination of aromatic compounds. Fluorinated aromatic compounds are valuable synthons for the chemical synthesis of pharmaceutical drugs and novel polymers. Fluorobenzene is used to control carbon content in steel manufacturing, is an intermediate for pharmaceuticals, pesticides and other organic compounds. Fluorobenzene is typically produced by the reaction of aniline and sodium nitrite in the presence of hydrogen fluoride. The present invention relates to a process for the synthesis of highly active binary metal fluoride system consists of copper (II) fluoride and aluminum (III) fluoride for the fluorination of aromatic compounds in gas phase and recycling of the reagent, in situ, using O 2 and HF.
