The present disclosure relates to a method of preparing powder of a solid carbazic acid derivative, which involves inducing a reaction of a liquid hydrazine derivative with carbon dioxide at a high pressure of from about 0.5 MPa to about 100 MPa. During the reaction, the pressure may range from about 0.5 MPa to about 100 MPa. In this regard, although the reaction of the carbon dioxide with the liquid hydrazine derivative occurs when the pressure is adjusted to below than about 0.5 MPa, sticky precipitates in a form of gel are gradually produced but the powder is not produced.
