The physical properties about this chemical are: (1)ACD/LogP: -1.20; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): -3.73; (4)ACD/LogD (pH 7.4): -2.04; (5)ACD/BCF (pH 5.5): 1; (6)ACD/BCF (pH 7.4): 1 ; (7)#H bond acceptors: 2; (8)#H bond donors: 4; (9)#Freely Rotating Bonds: 1; (10)Enthalpy of Vaporization: 41.8 kJ/mol; (11)Boiling Point: 113.5 °C at 760 mmHg; (12)Vapour Pressure: 20.7 mmHg at 25°C.

Preparation of Hydrazine hydrate: There are several methods to prepare this chemical. For example, it can be made by urea. First, mix the sodium hypochlorite and sodium hydroxide by a certain percentage. And add the mixture of urea and a small amount of potassium permanganate while stirring. Second, pass the steam directly into reactor at the temperature of 103 ~ 104 ℃. The oxidation reaction begins. Third, obtaine 40% hydrazine hydrate by fractional distillation and vacuum concentration. At last, 80% hydrazine hydrate is prepared by dehydration with caustic soda, vacuum distillation. The reaction is as follows:
NH₂ONH₂ + NaC1O +2 NaOH → N₂H₄^.H₂O + NaC1 + Na₂CO₃

Uses: It is used as reductant for hydrazine hydrate, medicine, pesticides, dyes, foaming agents, imaging agent, antioxidant materials. It is also used in the manufacture of high-purity metal, synthetic fiber, the separation of rare. In addition, the material can be used to manufacture rockets and explosives.
