Hydrazine Hydrate: generalized antioxidants refers radical scavengers of reactive oxygen species and blocking agents repair agent material collectively [1]. That can only remove free radicals and reactive oxygen species is reducing antioxidants, reducing agents and antioxidants are not peer concept, but not called another name. The reducing agent itself is oxidized to lose electrons oxidation products, such as the reduction reaction of copper oxide with hydrogen, the hydrogen is oxidized into water loses electrons. Reducing performance in reducing the reaction. Reducing power loss of strength is reducing the strength of hydrazine hydrate electronic capabilities, such as the number of sodium atoms lose electrons less than aluminum electronics, reducing power of sodium atoms is stronger than aluminum atoms. Containing substance used as a reducing agent is easy to lose electronic elements, particularly in the analysis of the reaction, common elements valence lift judgment: the valence of the elements contained elevated substance as reducing agent. Application of hydrazine hydrate and the dye in the wire electrode, for example Mn, Si, Al, Ti and Zr and other elements, can effectively prevent the infiltration of oxygen and so will not form an oxide in the weld metal pores [2]. Chlorine chlorine water will produce hypochlorous acid hydrazine hydrate reducing foam, hypochlorous have purification for disinfection - HClO generated soluble in water with strong oxidizing hydrazine hydrate: chemical equation is: Cl2 + H2O = HCl + HClO (reversible reaction) reaction of chlorine and alkali solution [Example] Cl2 + 2NaOH = NaCl + NaClO + H2O 2Cl2 + 2Ca (OH) 2 = CaCl2 + Ca (ClO) 2 + 2H2O these two reactions, Cl2 as oxidant and Restore agent is disproportionation. Cl2 + 2OH (-) (cold) = ClO (-) + Cl (-) + H2O 3Cl2 + 6OH (-) (hot) = ClO3 (-) + 5Cl (-) + treatment process: Wastewater Containing Cr6 + → Adjust Pool → → coagulation reaction reduction reaction cell sedimentation tank → → → pH correction filter tank → emissions. Under normal temperature for the yellow-green chlorine gas price of hydrazine hydrate, can be liquefied compressed golden yellow liquid chlorine, is one of the main products of the chlor-alkali industry, with a strong oxidant and chlorinating agent. Chlorine mixing 5% (by volume) or more explosive hydrogen gas. With organic and inorganic chlorine substitution or addition reaction of various chlorides. Chlorine early as paper, textile industry bleach. Cleaning hydrazine hydrate refining agent _ Wei Connaught Chemical (certified) _ hydrazine hydrate is provided by Qingdao Wei Connaught Chemical Co.
