PURPOSE: A manufacturing method of solid carbamic acid derivatives is provided to react amine with carbon dioxide under high pressure condition without using solvent, thereby capable of easily manufacturing solid carbamic acid derivative powder without side product. CONSTITUTION: A manufacturing method of solid carbamic acid derivatives comprises a step of reacting liquid amine derivatives and carbon dioxide under temperature of (-30)-500 °C and pressure of 0.3-100 MPa. The liquid amine derivative is in chemical formula 1. In chemical formula 1, R and R' is respectively and independently an alkyl group substituted or unsubstituted by N, a phenyl group substituted or unsubstituted by N, an aryl group substituted or unsubstituted by N, or a cycloalkyl group substituted or unsubstituted by N. The content of an amine group(-NH) in the amine derivative is 50-99 weight%. |
