Hydrazine hydrate with cas registry number of 7803-57-8 is a colorless fuming liquid with a faint ammonia-like odor. It also has other registry numbers including 65209-65-6, 65492-74-2, 79785-97-0. Its EINECS registry number is 206-114-9. This chemical is stable, but incompatible with a wide variety of materials, including oxidizing agents, heavy metal oxides, dehydrating agents, alkali metals, rust, silver salts. It belongs to the following categories: Biochemistry; Reagents for Oligosaccharide Synthesis; Synthetic Organic Chemistry; Water Ttreatment Chemicals. In addition, this chemical has a systematic name which is called hydrazine hydrate (1:1). And its IUPAC name is called hydrazine hydrate.
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.
When you are using this chemical, please be cautious about it as the following:
This chemical causes burns. It also may cause cancer and sensitization by skin contact. The most important thing is that it is very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. Therefore, avoid exposure before use. And avoid release to the environment. This material and its container must be disposed of as hazardous waste. In case of accident or if you feel unwell, seek medical advice immediately.
You can still convert the following datas into molecular structure:
