A composition and method of manufacturing the same. Embodiments of an aspect of the invention relate to the formula C(CH2NF2)4 having the name octafluoropentaerythrityltetramine (octafluoro-PETA). In embodiments of another aspect generally relate to a method for manufacturing octafluoropentaerythrityltetramine (octafluoro-PETA) including, basifying pentaerythrityltetramine tetrahydrochloride in an aqueous solution with an aqueous alkali and treating with alkyl chloroformate for producing a tetraalkyl pentaerythrityltetra carbamate, extracting the compound into a nonaqueous solvent suitable for extraction from water and removing the solvent for providing a pure form of tetraethyl pentaerythrityltetracarbamate, bubbling elemental fluorine and/or mixtures of fluorine with an inert gas through tetraalkyl pentaerythrityltetracarbamate in a solvent suitable for direct fluorinations of protected amines until excess fluorine appears, and purifying the resultant octafluoropentaerythrityltetramine.
一种组合物及其制造方法。发明的一个方面的实施例涉及具有名称八氟四甲基四氮唑基乙烷(八氟-PETA)的化学式C(CH2NF2)4。另一个方面的实施例通常涉及一种制造八氟四甲基四氮唑基乙烷(八氟-PETA)的方法,包括在含有水性碱的水溶液中碱化四氯化四羟基四甲基四氮唑,用含有水性碱的水溶液处理烷基氯甲酸酯以产生四烷基四甲基四氮唑基四氨基甲酸酯,将化合物提取到适合从水中提取的非水溶剂中,并去除溶剂以提供纯的四乙基四甲基四氮唑基四氨基甲酸酯形式,将元素氟和/或氟与惰性气体的混合物通入适合直接氟化保护胺的溶剂中的四烷基四甲基四氮唑基四氨基甲酸酯,直到出现过量氟,并纯化所得的八氟四甲基四氮唑基乙烷。
