China in the late Qing Dynasty chemist enlightenment Shou first time nitrogen translated into Chinese had written" light gas "United oxygen cleaning agent, meaning that it" dilutes "the oxygen in the air. Element name comes from the Greek, meaning" saltpeter. "Hydrazine is a widely used chemical raw materials having a high heat of combustion, can be used as rocket fuel and fuel cells. Hydrazine is a strong reducing agent linked oxygen, it can be used to remove water and hot water boiler heating system of oxygen, to reduce corrosion in the hydrazine molecule, since there are two nucleophilic nitrogen and four for the replacement of hydrogen-linked oxygen factory, with the help of various derivatives can be synthesized in animals, groups including plastic foaming agents, antioxidants, various polymers, polymer crosslinking agents and chain extenders, pesticide , herbicides, plant growth regulators and medicines. hydrazine highly toxic. mice oral LD50 of 59mg / kg, intravenous LD50 of 57mg / kg.4. system blowing agents, crop pesticides and water treatment agent.
