MANUFACTURING METHOD OF SOLID CARBAZIC ACID DERIVATIVE POWDER CAPABLE OF USING WITHOUT SOLVENT AND HAVING EXCELLENT REACTIVITY LIKE ANHYDROUS HYDRAZINE

摘要

PURPOSE: A manufacturing method of solid carbazic acid derivative powder is provided to reduce time and energy required for solidification by using carbon dioxide in high pressure and to manufacture pure solid cirque baz acid derivative powder.;CONSTITUTION: A manufacturing method of solid carbazic acid derivative powder comprises a step of reacting hydrazine derivative which is represented by chemical formula 1 with carbon dioxide under 0.5-100 MPa. In the chemical formula 1, R1-R3 respectively independently indicate hydrogen, alkyl group, cycloalkyl, phenyl, nitrophenyl, or aryl. The reaction under high-pressure condition is processed in water, C1-12 alcohol, C1-12 ether, or a mixed solvent thereof. The high-pressure condition is 1-50 MPa.;COPYRIGHT KIPO 2012
