Changzhou hydrazine hydrate, hydrazine hydrate plant, Zhongzheng Chemical (certified merchants)

Physical properties of freezing point: -51.7 ℃ Melting point: -40 ℃ Boiling point: 118.5 ℃ Relative density (water = 1): 1.032 (21/4 ℃ hydrazine hydrate, 21 ℃ means of hydrazine hydrate and at 4 ℃ than the density of water) vapor pressure : 72.8 ℃ gravity: 1.03 (21 ℃) surface tension (25 ℃): 74.0mN / m Refractive Index: 1.4284 generate heat: -242.71kJ / mol Flash point (open cup): 72.8 ℃ Solubility: hydrazine hydrate liquid the presence of hydrazine hydrate plant dimeric form, with water and ethanol, insoluble in ether and chloroform by the system hydrazine method Raschig invention came in 1906. This method ammonia as the nitrogen source, ammonia oxidation with sodium hypochlorite to hydrazine hydrate. Reaction principle is: NH3 + NaClO → NH2Cl + NaOH NH2Cl + NH3 + NaOH → N2H4 · H2O + NaCl overall reaction: 2NH3 + NaClO → N2H4 · H2O + NaCl Changzhou hydrazine hydrate, hydrazine hydrate plant, Chiang Kai-shek Chemical (certified merchants) CKS is provided by Jinan Chemical Co.
