The present invention features that during the synthesis and reduction of water soluble nitro-azo compounds, the produced thiosulfate is oxidized with water solution of sodium hypochlorite in concentration of 5-13 % into soluble sulfate according to the chemical reaction equation of 4NaClO+Na2S2O3+2...
Removal of the remaining proton on the nitrogen atom triggers rearrangement with concomitant expulsion of the halide ion to afford isocyanates which are immediately hydrated and then decarboxylate insitu. Consequently, only unsubstituted amides are capable of undergoing the Hofmann reaction.doi:10.1080/...
In this equation: Sodium hydroxide (NaOH) reacts with chlorine gas (Cl2) in the presence of water (H2O). The result of the reaction is the formation of sodium hypochlorite (NaClO), sodium chloride (NaCl), and water (H2O). Sodium hypochlorite (NaClO) is the active ingredient in bleach re...
Anhydrous sodium hypochlorite explodes; the pentahydrate is a pale-green crystalline solid; orthorhombic structure; density 1.6 g/cm3; melts at 18°C; decomposed by CO2 in the air; soluble in water, 29.3 g/100 mL at 0°C; the aqueous solution is highly stable. ...
Anhydrous sodium hypochlorite; may be obtained by freeze-drying in vacuum (over concn sulfuric acid;). Addition of chlorine; to cold dilute solution of sodium hydroxide;. 3.6 Usage Aq solution as bleach, disinfectant; chlorination of swimming pools; sanitation of drinking water....
Portable apparatus for the production of a dilute solution of sodium hypochlorite from a dilute solution of sodium chloride in water is described. The apparatus comprises: a container 1, at least two titanium, or titanium coated with noble metal, electrodes 2, 3, and a circuit connected to an...
Chemical reaction of main polymer and additive with oxidative cleaning agents plays an important role in aging of polymeric membrane for water and wastewater treatment. As a green and powerful oxidant, hydrogen peroxide (H2O2) can achieve good cleaning efficacy under alkaline condition, but its influe...
direct andmetal complexdyes are decolorised readily by hypochlorite, but water-insoluble disperse and vat dyes are resistant to decolorisation in this process.40−41Decolorisation of reactive dyes require long reaction times, while metal complex dye solution remains partially coloured even after an...
Solution reaction: 2NaOH + Cl2 → NaCl + NaClO + H2O The electrolysis process of the electrolytic brine type sodium hypochlorite generator is an electrochemical reaction process. Its only raw materials are salt and water. The sodium hypochlorite solution is made of pure quality. Although the chemi...
With the aim to identify the reaction by-products, the oxidation of four sulfur-containing s-triazines (prometryne, terbutryne, ametryne and desmetryne) by sodium hypochlorite (NaClO) has been investigated using oxidant and herbicides in... A Lopez,G Mascolo,G Tiravanti,... - 《Water Sci...
