BIUREA Usage And Synthesis
Chemical PropertiesWHITE POWDER
UsesHydrazine-1,2-dicarboxamide is a useful compound in the process of producing protected anode active material particles for rechargeable lithium batteries.
General DescriptionWhite powder.
Air & Water ReactionsInsoluble in water.
Reactivity ProfileBIUREA is chemically classified as an amide. Amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).
Fire HazardThe flash point of BIUREA is not available, however BIUREA is probably non-flammable.
Purification MethodsCrystallise the diamide from water, wash the crystals with EtOH then Et2O and dry in vacuum over P2O5. It does not decompose on drying at 110o /48hours. Its solubility in H2O is 1% at 0o. [Andrieth & Mohr Inorg Synth IV 26 1953, Beilstein 3 H 116, 3 I 56, 3 III 229.]
