用途有機合成原料。

使用2-Hydroxyethylhydrazine is used as an intermediate, plant growth regulator, flowering inducer for pineapples.

一般的な説明2-Hydroxyethylhydrazine reacts with β-diketones having strong electron-withdrawing substituents to yield 5-hydroxy-4,5-dihydropyrazoles.

調製方法 · 1 件

製造方法2-Hydroxyethylhydrazine is prepared by heating about 2 to 17 parts of hydrazine hydrate dissolved in water to about 30℃ to about 100℃. in a closed system. Then, 1 part of ethylene oxide is gradually added to the hydrazine hydrate, and the temperature of the reaction mixture is maintained in the range of about 30℃ to 70℃ during the addition.
