1, Yinglite: Yinglite said on the interactive platform on June 22, 2020 that the company's main products are PVC, paste resin and caustic soda, and the raw materials of disinfectants such as hydrochloric acid, liquid chlorine and sodium hypochlorite are by-products of the company. The stock price rose by 9.69% in recent 7 days, and fell by -2 1.73% in 2022.
Main business: production and sales of calcium carbide and its series of extended products; Production and sales of PVC, caustic soda and its series of extended products; Production and sales of special resins; Production and sales of electric power and heat.
2. Walter Dyne: The environmental protection department has a series of products such as chlorine dioxide generator, sodium hypochlorite generator and ozone generator. It is an intelligent collaborative disinfection expert with the best product quality and the most complete variety in the industry.
Hypochloric acid:
It is a weak acid and the dao system is unstable. Because it is easy to decompose, Bai has never heard of Du's direct preparation of pure cheese hypochlorite in industry and laboratory (it is difficult to prepare, at least it was not mentioned before high school). ?
It is common in industry to prepare calcium hypochlorite and sodium hypochlorite: 2Ca(OH)2 (lime milk) +2Cl2 (chlorine) == CaCl2+Ca(ClO)2 (calcium hypochlorite) +2H2O (finally, the solid mixture containing CaCl2 is relatively stable.
That is, bleaching powder) 2NaOH+Cl2 == NaCl+NaClO (sodium hypochlorite) +H2O (disinfectant can be obtained at last, which is also relatively stable). When bleaching powder and disinfectant are used, the air contains CO2, which is dissolved in water to generate carbonic acid, and strong acid is used to generate weak acid to obtain hypochlorous acid.
Disinfection effect: ca (clo) 2+2co2+2h2o = = ca (hco3) 2+2clonaclo+Cl2+H2O = = HCl+hclo There should be no pure hypochlorous acid in the laboratory (I think it is impossible), so Cl2+H2O can be used instead.
