Anwendungen & Verwendung
Verwenden
2-Hydroxyethylhydrazine is used as an intermediate, plant growth regulator, flowering inducer for pineapples.
Herstellung & Synthese
synthetische
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.
