Zwitterionic imides

   
   

Zwitterionic imide compounds are provided according to the formula: R.sub.1 --SO.sub.2 --N.sup.- --SO.sub.2 --R.sub.2.sup.+, where R.sub.1 and R.sub.2.sup.+ are any suitable groups. Typically R.sub.1 is a highly fluorinated alkane and R.sub.2.sup.+ contains a quaternary ammonium group or a heteroatomic aromatic group having an cationic nitrogen, such as: pyridiniumyl, pyridaziniumyl, pyrimidiniumyl, pyraziniumyl, imidazoliumyl, pyrazoliumyl, thiazoliumyl, oxazoliumyl, or triazoliumyl. Zwitterionic liquids are provided, typically having melting points of less than 100.degree. C. and typically having a solubility in water of less than 5% by weight.

Os compostos do imide de Zwitterionic são fornecidos de acordo com a fórmula: R.sub.1 -- SO.sub.2 -- N.sup. - -- SO.sub.2 -- R.sub.2.sup.+, onde R.sub.1 e R.sub.2.sup.+ são todos os grupos apropriados. Tipicamente R.sub.1 é um alkane altamente fluorinated e R.sub.2.sup.+ contem um grupo do ammonium quaternary ou um grupo aromatic heteroatomic que têm um nitrogênio cationic, como: pyridiniumyl, pyridaziniumyl, pyrimidiniumyl, pyraziniumyl, imidazoliumyl, pyrazoliumyl, thiazoliumyl, oxazoliumyl, ou triazoliumyl. Os líquidos de Zwitterionic são fornecidos, tipicamente tendo pontos de derretimento de menos do que 100.degree. C. e tipicamente ter um solubility na água menos de de 5% pelo peso.
