hydrazine monohydrate is a colorless, fuming and basic solution with a peculiar bad smell, soluble in water and alcohol, insoluble in chloroform and ethyl ether, flammable and corroding glass, rubber and leather, hydrazine hydrate's severe toxicity accumulates and harms blood and nerves
Hydrazine hydrate and its derivative products are widely used in many industrial applications, such as chemical products, pharmaceutical products, agricultural products, water treatment, used as reducing agents, antioxidants, such as photography and photographic products, used in the production of pharmaceuticals, foaming agent and so on.
Hydrazine can be directly used :
1 thermal and nuclear power plants as a circulating water corrosion additives.
(2) industrial boilers and high pressure steam oven water oxygen scavenger . Hydrazine hydrate is a deoxidizer , which enables reduction of dissolved oxygen in the water , boiler feed water is used to further remove the residue after thermal oxygen by trace dissolved oxygen. Because for dissolved oxygen can cause corrosion of boiler tubes . The boiler feedwater hydrazine hydrate , not only oxygen, but also to prevent fouling of iron and copper boiler scale formation .
Hydrazine is a highly reducing agent , can be synthesized by the following products:
1 foaming agent : azodicarbonamide ( azo -carboxamide ) ( eg : for the production of tubes with sodium azide product ) .
(2) agricultural products and pharmaceutical products in the synthesis of biologically active intermediates , first generation triazole.
3 Azo initiators
4 various other products: The dye certain organic pigments , photographic reagents aspect , urethane and acrylic products, and products cyanide bromate
Hydrazine can also be applied in the following areas :
1 of precious metals cleaning, refining.
2 pickling and surface treatment of metal was recovered .
3 . Handling waste and emissions.
4 for use in the electronics market various grades of sulfuric acid refined purification .
5 of plastic and metal ( nickel, cobalt, iron , chromium, etc. ) of a metal inlay.
6 is a rocket fuel formulations.
7 In the ACTIRED used in the process , the process is mainly used in gold processing .
As a bifunctional hydrazine group and a nucleophilic group , it can produce a variety of derivative products, such as :
1. LIOZAN: Anti- corrosion products , can provide rapid oxygen capacity, and can be effective at lower temperatures .
2 hydrazine salt : three kinds of products, mainly for the synthesis of intermediates ( particularly in the pharmaceutical industry ) .
3 triazole products: 1,2,4 - triazole / 1,2,4 - triazole sodium salt / 4 - amino-1 ,2,4 - triazole / 3, - amino-1 ,2,4 - three azole .
4 aminoguanidine bicarbonate.
