It is also used to make isoniazid , Nitrofurazone, Diazonium hydrazine, Anhydrous hydrazine, etc. It is also used as a reducing agent, insecticide and sterilant. Hydrazine sulfate is a nutritional supplement in the United States to combat the symptoms of anorexia and weight loss caused by cancer.
肼硫酸盐的实验室制备方法
- 使用氯和氢氧化钠制备次氯酸钠,然后与氨反应以使肼水合物,最后脱水制成肼,然后与硫酸反应制备肼硫酸肼产物。相关化学反应方程如下:2NH3 + NaClO→NH 2 Cl + NaOHH 2 Cl + NaOH + NH 3→N 2 H 4 + NaCl + H2On2H4 + H 2 SO 4→N 2 H 4·H 2 SO 4。
- 氨气与水反应,得到氨水,然后合成,得到脱肼溶液,其蒸发,浓缩,结晶,并最终与硫酸反应,得到硫酸肼的成品。
