摘要
The present invention relate to a method for concentrating hydrazine hydrate by making a hydrazine solution having low density react to carbon dioxide, and to a hydrazine hydrate manufactured by the same. The method includes the steps of: removing excessive water in the solution after forming a hydrazine-carbon dioxide compound by making the hydrazine solution having low density react with carbon dioxide; and forming the hydrazine hydrate concentrate by making the hydrazine-carbon dioxide compound react with water or steam. The method of the present invention is economic and is used to produce hydrazine hydrate in high density with little energy.
