84 disinfectant
Disinfectant 84 is a chlorine-containing disinfectant with sodium hypochlorite as the main component, which is mainly used to disinfect the surfaces of various objects and the environment. The hypochlorous acid produced by sodium hypochlorite in aqueous solution can decompose new ecological oxygen, which is highly oxidizing and can oxidize the nucleic acid substance of the virus, thus killing the virus.
Colorless or light yellow liquid, with pungent smell, with available chlorine content of 5% ~ 7%. Widely used in hotels, tourism, hospitals, food processing industries, families and other sanitary disinfection.

Bleaching principle
NaClO has strong oxidation and is used as bleaching agent. Its bleaching principle is that NaClO is hydrolyzed to produce bleached HClO (hypochlorous acid). HClO is a weak acid, which is weaker than carbonic acid. However, it has a strong oxidizing property, which can oxidize and denature reducing substances, so it can play a disinfection role. CO2 (carbon dioxide) in the air can be dissolved in NaClO solution and react with NaClO to obtain bleached HClO.
The chemical reaction equation is:

From June 65438 to June 0992, ditan hospital established Beijing Longan Medical Technology Development Company (hereinafter referred to as Longan Company) and entrusted it to produce and sell "84" disinfectant. The two sides agreed that all legal disputes in the production, research and development, operation and sales of "84" disinfectant in the future will be settled by ditan hospital in the name of ditan hospital. 1March 1997, ditan hospital also transferred its technology and licensed it to more than 30 manufacturers nationwide to produce and sell "84" disinfectant.
