n.肼；联氨
Hydrazine perchlorate and lithium perchlorate form two eutectics. 过氯酸肼和过氯酸锂形成两种低共熔物。
The material is readily prepared by reaction of formaldehyde and hydrazine. 这种物质很容易由甲醛和肼反应而得到。
Hydrazine is similar to chlorine or ammonia in that it affects the lungs and breathing tissue. 联氨类似氯或氨，它会影响肺部及呼吸组织。
If they are accumulated to a considerable level, elimination of these ions can be carried out by an addition of strong reducing agent such as hydrazine. 如果他们累积到相当大的水平，要除去这些离子是可以透过增添像联氨这样强的还原剂来完成。
