(1). Hydrazine hydrate,also called Diamide hydrazine,its pure form is colorless transparent oily liquid, with light ammonia odor,smokes in wet air,and has strong alkaline and hygroscopicity.Under atmospheric pressure,it can form an azeotropic hydrazine with water (hydrazine in the azeotrope is about 69%).The general content of industrial application is 40%-80% hydrazine hydrate or hydrazine salt aqueous solution.
(2). Its liquid exists with the form of two prepolymer,can be miscible with water and ethanol,but insoluble in ether and chloroform;it can corrode glass,rubber,leather,cork,and decomposed into N2,NH3 and H2 at high temperature.It has extremely strong reducibility,it has fierce reaction with halogen,HNO3 and KMnO4,etc. It can absorb CO2 in the air and smoke.
2. Propertites and application
Avoid touch with the oxide,oxygen,metal powder,organic material,the staff should make comprehensive protection,hydrazine,skin and eye contact should be directly use amount of top water wash,and doctors check,please.The working area must be fully ventilated and regularly used to detect the concentration of hydrazine in the production area.Can be mixed with water and alcohol, not dissolved in chloroform and ether.Strong alkaline and reductive is a strong reducing agent.Contact with oxidizer will spontaneously ignite.It is highly corrosive and permeable.You can absorb carbon dioxide in the air.Poisonous.Refractive ability is very strong liquid.Smoke in the air is quite difficult to flow,and it is not like ammonia.Can be mixed with water and alcohol, cannot be mixed with ether and chloroform.
(1). it is an important fine chemical raw materials,mainly used for the synthesis of AC,D1PA,TSH and other foaming agent;also use as boilers and reaction kettle deoxidation and decarbonization cleaning agent;used for the production of anti-Tuberculosis and anti-diabetic drugs in the pharmaceutical industry;used for the production of herbicides,plant growth regulators and sterilization,insecticide,rodenticide in the pesticide industry.In addition,it can also be used to produce rocket fuel, diazo fuels, rubber chemicals.
(2). its derivative products are widely used in many industrial applications,such as chemical products,
pharmaceutical products,agricultural products,water treatment,photography and photographic products as reductants,oxygen scavenger and antioxidants,and used for the preparation of medicine,foaming agent.
4. Production method
Hydrazine hydrate,industrial production methods mainly include raschig,urea,ketone 4 even nitrogen and hydrogen peroxide method,the current domestic main urea method is used to process.
1).The urea oxidation method
Mix 10% sodium hypochlorite solution and 30% liquid alkali,then cooling,adjust the mix,and then cooling, adjust the mixture of chlorine and alkali into 1:1.8 weight ratio,reaction pot.Add just the right amount of potassium permanganate, reaction pot, mix urea solution will be heated to about 103-104ºC material liquid boiling.The amount of urea in terms of available chlorine than the weight of the active chlorine is 76:75.
The above crude hydrazine oxidation products vacuum distillation was added to the evaporator, hydrazine gas and moisture after blind wind machine import accept kettle,for the first time to ask.Get light hydrazine water from accepting kettle will be sent to the sieve plate tower for the vacuum concentration, the content of hydrazine hydrate to the specified value.When the content of 40% or higher urea 770 890030% sodium hypochlorite liquid alkali 770.Sodium hypochlorite ammoniation method first a mixture sodium hypochlorite,chlorine and caustic soda and then in the 3.922 x 107 pa under pressure and 130-150 ºC temperature synthesis,hydrazine hydrate reaction liquid, the bullishness of removing excess ammonia,then evaporative desalination and rectification finished hydrazine hydrate.
