Hydrolysis of polyurea under high pressure of carbon dioxide
A chemical decomposition of polyurea (PUA) by hydrolysis under high pressure of carbon dioxide (CO2) was proposed. The hydrolysis of PUA was carried out at 190 °C for 2 h under 7.0 MPa of CO2 in the presence of water. The hydrolysis reaction gave white residual solid and water soluble compound. The...
