In this method, ketone imine is generated by the reaction of butanone (methyl-ethyl ketone) and ammonia, and then oxidized to oxazizone with H2O2, and then ammoniated to methyl-ketone nitrile. The latter is hydrolyzed into hydrazine and ketone, and the unreacted ketone can be recycled after purification.
The ketorenazone method, also known as Bergbau-Bayer-Whiffen method, was developed in the 1960s. It was first patented by Bergbau-Farsching, a subsidiary of the German Coal Mining Association. The process was improved by Bayer and Whiffen & Sons. Respectively, in the mid 1970s, large-scale industrialization and rapid development, is actually an improvement of the original Lacey law.
There are four industrial production methods of hydrazine hydrate: lacey method, urea method, ketone nitrogen method and hydrogen peroxide method. At present, urea method is mainly used in China. 2.1.1 Raschig method This process, first used in industrial production in 1906, produces hydrazine.
The main industrial production methods of hydrazine hydrate are laxi method, urea method, ketone nitrogen method and hydrogen peroxide method. The urea process is mainly used in China. 1. Urea oxidation method Mix 10% sodium hypochlorite solution with 30% liquid alkali, then cool, adjust the mix
Hydrazine hydrate, as an important fine chemical raw material, is mainly used in the synthesis of AC, D1PA, TSH and other foaming agents. Also used as boiler and reaction kettle deoxidation and carbon dioxide cleaning treatment agent; In the pharmaceutical industry for the production of anti-tuber
Hydrazine hydrate, also known as hydrazine hydrate, has strong alkalinity and hygroscopicity. Pure product is colorless and transparent oily liquid, with light ammonia flavor, smoking in wet air, with strong alkalinity and hygroscopicity. Generally used in industry, the content of hydrazine hydrat
Production methods of hydrazine hydrate: There are many production methods. 1. Urea oxidation method mix 10% sodium hypochlorite solution and 30% liquid caustic soda, then cool, adjust the mixing, then cool, adjust the weight ratio of chlorine and alkali in the mixture to 1:1.8, and put it into the
Energy is the most essential cause that drives all things. Whether it is the driving of the ground car or the flying of the rocket/aircraft, it is simply a process of obtaining kinetic energy in the form of some energy conversion! The engine of a car simply uses the energy generated by rotation to d
The downstream of the hydrazine hydrate industry chain is mainly in chemical, pharmaceutical, pesticide, power, water treatment, aerospace and other industries.Hydrazine hydrate, also known as hydrazine hydrate, pure product appearance for colorless transparent oily liquid, a light ammonia taste, to
