Urea → Carbon Dioxide

Participants

Reaction Steps

In the NPL1, a method, in which urea (CO(NH2)2) and fluorosulfonic acid (FSO3H) are mixed first, and then the resulting mixture is heated to proceed the chemical reaction between them, is disclosed. In this reaction, the chemical reaction represented by the formula (1) below proceeds, producing bis(fluorosulfonyl)imide, ammonium hydrogen sulfate (NH4HSO4), hydrogen fluoride (HF), and carbon dioxide (CO2). The produced bis(fluorosulfonyl)imide and the fluorosulfonic acid that is input excessively can be recovered by distillation under reduced pressure. 3FSO3H+CO(NH2)2→(FSO2)2NH+NH4HSO4+HF+CO2  (1)
