Hydrazine hydrate, with a strongly alkaline and hygroscopic . Pure product is colorless transparent oily liquid with a light ammonia odor, smoke in the wet air, with a strongly alkaline and hygroscopic . Liquid hydrazine hydrate with water and ethanol, insoluble in ether and chloroform; it can erode glass, rubber , leather, cork , etc., decompose at high temperatures into N2, NH3 and H2; hydrazine highly , with halogens , HNO3 , KmnO4 other violent reaction in the air can absorb CO2, produce smoke . Hydrazine and its derivatives products in many industrial applications has been widely used as a reducing agent , antioxidant, used for making medicine , foaming agents , etc.
Use
Hydrazine hydrate as an important fine chemical raw materials, mainly for the synthesis of AC, D1PA, TSH and other foaming agent ; also used as boiler and reactor deoxidation and cleaning off the carbon dioxide treatment agent ; in the pharmaceutical industry for the production of anti- tuberculosis, anti-diabetic , anti-tumor drugs ; in the pesticide industry for the production of herbicides, plant growth reconcile agent and sterilization, insecticide, rat poison ; addition, it can also be used to produce rocket fuel , diazo fuel , rubber additives , car airbags, LCD intermediates. In recent years, applications of hydrazine hydrate are still expanding.
a) for the synthesis of a foaming agent . With hydrazine hydrate as raw material to manufacture ADC foaming agent , and its gas evolution obviously much higher than other similar products , and non-toxic , tasteless, not color, not bad.
b) for the synthesis of pesticides. Hydrazine derivatives are used as a pesticide plant growth regulator maleic hydrazide derivatives , rodenticides two mice agent dinitrophenylhydrazine , insecticidal agents nails pyrazole derivatives with a 5 - nitrofuran thioacetazone , weeding agents such as amino- triazole .
c) medicine . Isoniazid, Fenji thioacetazone , benzenesulfonyl thioacetazone , antipsychotics 1 - Isonicotinic acetyl-2 - isopropyl hydrazine, hydrazine derivatives aldehyde anticancer drugs ,
Hydrazine can be directly used :
Industrial boilers and high pressure steam boiler in 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 foam: Most of the hydrazine derivative as a blowing agent is azodicarbonamide (AC), and p-toluenesulfonic acid hydrazide . ( Azo- carboxamide ) ( eg : tube used for the production of 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 esters , and cyanide bromate products.
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 .

How to choose silica gel supplier
Usage by Product Category
1 , medicinal , food silica gel desiccant
Food and Drug silica gel desiccant criteria are to meet State Food and Drug Administration to develop pharmaceutical packaging containers ( material ) Standard: " Medicinal solid desiccant paper bags standard " , the standard provides for " solid dosage filter bags packed spherical pore silica gel desiccant "requirement, which in addition to the desiccant bag appearance , strength, moisture adsorbent , desiccant moisture absorption rate and other basic performance requirements, focusing on the content of harmful substances in the desiccant ( eg : arsenic , etc. ) , microbial limits , bleaching performance and other aspects of the regulations.
2 , shoes with silica gel desiccant
Shoes with silica gel desiccant can be considered for general cargo dry, moisture desiccant. The main requirement silica gel desiccant itself does not contain relevant international standards in the prohibited substances , packaging materials Breathable and durable, while its upper reaches other desiccant adsorption effect can not be achieved .
3, Electronic products with silica gel desiccant
Electronic products, especially for packaging moisture-sensitive electronic components and humidity control also has a very high demand , the United States Association Connecting Electronics Industries (IPC) and the U.S. Joint Electron Device Engineering Council (JEDEC) jointly prepared " moisture-sensitive surface mount components packing and shipping process using the standard "
J-STD-033b is being widely used for moisture-sensitive electronic components surface treatment, drying, drying and packaging requirements in all aspects of the comprehensive standard . The standard provisions in Chapter 3 of these electronic components dry packaging requirements.
4 , the container with silica gel desiccant
Container with silica gel desiccant is mainly used for shipping containers , used to adsorb the ocean containers during transport or storage container and humid climate and the oceans since experienced a large diurnal temperature variation inside the container into water vapor will condense beads and the formation of the " container rain " , to reduce the moisture content of the air in the container to prevent the generation of container rain .
