하이드라진 황산염 C화학적 특성, 용도, 생산
화학적 성질
colourless crystals or white powder물리적 성질
Colorless orthorhombic crystal; density 1.378 g/cm3; melts at 254°C; sparingly soluble in cold water 1.64% at 0°C and 3.41% at 25°C; more soluble inhot water; practically insoluble in alcohol (0.04% at 25°C).용도
Hydrazine sulfate is used in the gravimetric estimation of nickel, cobalt and cadmium; in the refining of rare metals; as an antioxidant in soldering flux for light metals; as a reducing agent in the analysis of minerals and slags; in separating polonium from tellurium; in tests for blood; for destroying fungi and molds; in the preparation of hydrazine hydrate; press ure stabilizer in cutting oils.제조 방법
Hydrazine sulfate may be synthesized from aqueous ammonia and sodium hypochlorite solution in a two-step process. In the first stage, aqueous solution of ammonia is boiled with a normal solution of sodium hypochlorite in the presence of 10% gelatin solution to yield hydrazine. In the second stage, the hydrazine solution is ice-cooled followed by slow addition of concentrated sulfuric acid (Adams, R., and B.K. Brown. 1964. In Organic Synthesis, Collective Volume I, ed. H. Gilman and A. H. Blatt, 2nd ed. pp 309-310, New York: John Wiley & Sons). The reaction steps are as follows:2NH3 + NaOCl → NH2NH2 + H2O + NaCl
NH2NH2 + H2SO4 → NH2NH2 •H2SO4
일반 설명
Hydrazine sulfate salt is a potential anticachexia agent for treating cancer patients.위험도
A carcinogen (OSHA).Carcinogenicity
Hydrazine and hydrazine sulfate are reasonably anticipated to be human carcinogens based on sufficient evidence of carcinogenicity from studies in experimental animals.Purification Methods
Its solubility in H2O is 3% at room temperature, but is very soluble in hot H2O. It is a suspected carcinogen. [Adams & Brown Org Synth Coll Vol I 309 1941, Audrieth & Nickles Inorg Synth I 90 1939.]하이드라진 황산염 준비 용품 및 원자재
