Abstract

The present invention relates to the synthesis of a novel compound, in which liquid hydrazine and the derivatives thereof react with excess carbon dioxide to enable the carbon dioxide to chemically bond to the hydrazine and the derivatives thereof. To this end, high-pressure carbon dioxide is used to synthesize hydrazine and the derivatives thereof to which the carbon dioxide is bonded in a pure form with no water and no by-product. Furthermore, the present invention provides a method for utilizing the above-described compounds by reacting the compounds with carbonyl compounds.
