The demand for hydrazine hydrate is rising and the hydrogen peroxide production process has great potential

Hydrazine hydrate is also called hydrazine hydrate, hydrazine, CAS number is7803- 57-8, the chemical formula isH₆N₂O, with a molecular weight of 50.053. Pure hydrazine hydrate is a colorless and transparent oily liquid with a light ammonia smell, smokes in humid air, and is highly alkaline and hygroscopic. Hydrazine hydrate products used in industry are generally hydrazine hydrate aqueous solutions with a content of 40%-80%.

Hydrazine hydrate liquid exists in the form of a dimer, is miscible with water and ethanol, and is insoluble in ether and chloroform; it can corrode glass, rubber, leather, cork, etc., and decomposes at high temperatures into N₂, NH₃ and H₂; hydrazine hydrate is extremely reducing, and is compatible with halogens, HNO₃, KmnO₄, etc. Reacts violently and can absorb CO₂ in the air, producing smoke. Hydrazine hydrate has become an important raw material and chemical intermediate in the production of various chemical products due to its strong reducing properties, alkalinity, hygroscopicity and other properties. For example, in medicine, hydrazine hydrate can be used to produce anti-tuberculosis and anti-diabetic drugs; In terms of pesticide production, hydrazine hydrate can be used in the production of herbicides, plant growth regulators, fungicides, insecticides and other pesticide products; in the chemical industry, hydrazine hydrate can be used in the synthesis of various foaming agents and the production of cleaning agents; in the military industry In the field, hydrazine hydrate is commonly used as rocket propellant, rubber additives, and fuel cell production.

According to the “2017-2022 Hydrazine Hydrate Industry Investment Environment and Investment Prospects Forecast Analysis Report released by the Industrial Research Center, it is relatively mature. There are four main hydrazine hydrate preparation processes, namely Raschien method, urea oxidation method, ketone azide method, hydrogen peroxide method (hydrogen peroxide method), etc. Among them, the Raschien method is the earliest hydrazine hydrate production process, but its hydrazine hydrate yield is low and the production cost is high, so it has been basically eliminated; the urea oxidation method also has a low yield, so this method is basically not used abroad, but its process is simple and The investment is low, so this method is still commonly used to produce hydrazine hydrate in China; the methacilazine method and the hydrogen peroxide method have high yields, low energy consumption, and simple processes, so they are the mainstream production methods of hydrazine hydrate in the world. As of 2021, the market size of my country’s hydrazine hydrate industry has reached 2.5 billion yuan.

At this stage, the main large-scale hydrazine hydrate enterprises in my country include Jiangxi Lanhengda Chemical Co., Ltd., Weifang Yaxing Chemical Co., Ltd., Changzhi Huojia Industrial Co., Ltd., Yibin Tianyuan Group Co., Ltd., etc., and most of these enterprises use relatively The backward urea process has high raw material costs and low production efficiency, which to a certain extent has hindered the growth of my country’s hydrazine hydrate production capacity.

Industrial researchers believe that downstream industries such as chemical, pharmaceutical, and military industries in my country are developing well. In the future, with the development of the above industries, their impact on The product quality requirements for hydrazine hydrate will continue to improve, and the market demand for it will continue to grow. Existing domestic enterprises and new enterprises need to speed up investment in technology research and development, promptly replace the more environmentally friendly and efficient hydrogen peroxide production process of hydrazine hydrate, avoid shutdowns and shutdowns caused by production pollution, reduce investment in pollution treatment costs, and improve product quality and additional costs. Value, thereby improving product competitiveness, gaining recognition from domestic and foreign customers, and increasing international market share.
