Hypochlorous acid — Hypochlorites

A 3-1., three-necked flask fitted with a mechanical stirrer, a dropping funnel, and a thermometer is then charged with an aqueous solution of 2.2 moles of calcium hypochlorite [Hypochlorous acid, calcium salt] (Note 3), and the piperidine acetate prepared above is placed in the dropping funnel. The hypochlorite solution is stirred and cooled to 0° to — 5° with a methanol-ice bath, and the piperidine acetate is added dropwise over a period of 1.25 hours while the temperature is maintained below 0°. After a further 15 minutes of stirring, equal portions of the mixture are placed in two 2-1. separatory funnels and extracted three times with a total of about 1300 ml. of ether. The ether extract is placed in a 2-1. flask and dried over anhydrous sodium sulfate in a cold room at 4° overnight. After filtration to remove inorganic material, the bulk of the ether is removed by boiling on a water bath maintained below 60° (Note 4). 

PPG [Pittsburgh Plate Glass Company] A process for making calcium hypochlorite. Hypochlorous acid and chlorine monoxide, generated by reacting chlorine and carbon dioxide with sodium carbonate monohydrate, are passed into lime slury. Invented in 1938 by I. E. Muskatt and G. H. Cady at the Pittsburgh Plate Glass Company. 

Cbemical/Physical. The aqueous chlorination of indole by hypochlorite/hypochlorous acid, chlorine dioxide, and chloramines produced oxindole, isatin, and possibly 3-chloroindole (Lin and Carlson, 1984).

It is still worth noting that in an early work (D Ans et al. 1957) the authors found that perchlorate is a by-product in reacting hypochlorite/hypochlorous acid with chlorate. It is explained by the fast formation of an activated complex [HC1204] that may slowly react to perchlorate, H+ and Cl-.

Exposure to a chemical can cause damage at the point or site of exposure if the substance is reactive, irritant, corrosive, or caustic. Thus substances such as kettle descaler (formic acid), battery acid (sulphuric acid), caustic soda (sodium hydroxide), and bleach (sodium hypochlorite/hypochlorous acid) can cause serious, and maybe permanent, damage to the skin, the eyes or the oesophagus, and stomach if they come into contact with these parts of the body. Unfortunately, people sometimes attempt suicide by swallowing such substances for example, drinking kettle descaler or bleach causes serious damage to the lining of the gut (see case notes, p- 193).

Hypochlorous Acid and the Hypochlorites. Hypochlorous acid, HCIO, and most of its salts are known only in aqueous solution they decompose when the solution is concentrated. A mixture of chloride ion and hypochlorite ion is formed when chlorine is bubbled through a solution of sodium hydroxide ... 

Hypochlorites hypochlorous acid, A solution of sodium or calcium hypochlorite is a more powerful oxidizing agent than oxygen. Hypochlorite solutions are alkaline, since hypochlorous acid is very weak. Hypochlorite is, therefore, a reagent for alkaline oxidations. An example of its use is given in Experiment 33, the preparation of lead dioxide, where the main reaction is Pb02 + 0C1 PbOs"" + Cl . Alkali facilitates this reaction since plumbic acid is stronger than plumbous.
