yau asked! far facts an Hydrazine is now available in several forms and in a number of derivatives. As a n exceptionally effec tive reducing agent, oxygen scavenger and nitrogen "building block," hydrazine has many uses. The salt derivatives make available the properties of the basic chemical. These forms may be more suitable where the process requires modified solubility or The fo//owing hydrazine

controlled reaction. The salt derivatives may also be preferred where longer storage or less careful handling is involved. A typical aliphatic derivative is beta-hydroxyethylhydrazine. I t has specific uses and is particularly interesting as an intermediate for combinations including ethylene or ethanolic groups.
