Hypochloride acid

The method of choice for preparing thietane oxides is the oxidation of thietanes. This can be conducted using hydrogen peroxide, sodium hypochloride -, sodium metaperiodate , NaI04 and m-chloroperbenzoic acid . 

Different immobilization methods were applied for Jacobsen s catalyst. The entrapment of the organometallic complex in the supercages of the dealuminated zeolite was achieved without noticeable loss of activity and selectivity. The immobilized catalysts were reusable and did not leach. For the oxidation of (-)-a-pinene the system used only O2 at RT instead of sodium hypochloride at 0 °C. There was a disadvantage in the use of pivalic aldehyde for oxygen transformation via the corresponding peracid. This results in the formation of pivalic acid, which has to be separated from the reaction mixture. 

Amplified DNA is identified by solution hybridization of two nonisotopically labeled oligonucleotides to one strand of the amplified DNA. Following hybrid formation DNA is bound to a solid phase and detected by enzyme-labeled specific antibodies. Because only one strand is used for detection, the other one is washed off and constitutes the main source of laboratory contamination and carryover. Take precautions to avoid the spread of these molecules to other rooms (e.g., work in a chemical fume hood, decontaminate used wash buffer with acid or sodium hypochloride, and so on). 

Oxidation of alcohols. Grob and Schmid used /-butyl hypochlorite in carbon tetrachloride or ether in the presence of pyridine for oxidation of cyclohexanol to cyclohexanone and of /i-butanol to //-butyl butyrate. Ginsburg et aU oxidized 3-hydroxysteroids by dropwise addition of /-butyl hypochlorite in CCli to a solution of the steroid in CCl, at room temperature. When the ketone was to be chlorinated as formed, the reaction was done in acetic acid at followed by heating on the steam bath. Levin et al. obtained 3-ketosteroids in high yield by oxidation of the 3-atcohols with /-butyl hypochloride in dry /-butanol. 

Oxidation of methyl ketones with hypochloride (or hypobromide) to carboxylic acids and chloroform with NaOH and iodine, iodoform is formed (see 1st edition).

An oil with the pleasant odor of lemons,a-terpinene, has been isolated from the marjoram plant. It has the formula CioHie- Upon ozonolysis, followed by an oxidative workup, it yielded two compounds oxalic acid and a neutral compound having the formula CaHiJ Oa. When oxidized with sodium hypochloride, the latter was converted to an acidic compound having the formula C7H12O3. This acidic compound was identified as 5-methyl-4-oxo-hexanoic acid. What is the structure of a-terpinene ... 

Surface oxidation reactions have been carried out on a number of polymers, particularly polyethylene. Surface oxidation techniques include the use of corona discharge, ozone, hydrogen peroxide, nitrous acid, alkaline hypochloride, UV irradiation, oxidizing flame, and chromic acid The reactions lead initially to the formation of hydroperoxides, which catalyze the formation of aldehydes and ketones and finally, acids and esters. Surface oxidation treatment has been used to increase the printabdity of polyethylene and poly(ethylene terephthalate) and to improve the adhesion of polyethylene and polypropylene to polar polymers and that of polytetrafluoroethylene to pressure-sensitive tapes. Surface-oxidized polyethylene, when coated with a thin film of vinylidene chloride, acrylonitrile, and acryhc acid terpolymers becomes impermeable to oxygen and more resistant to grease, oil, abrasion, and high temperatures. The greasy feel of polyethylene has also been removed by surface oxidation.

It is found that antiseptic agents also give strong effect when combined with each other. Moreover, goods results are reached by application of sodium hypochloride, boric acid, sodium borate, zinc chloride, sodium fluoride, benzene and phenol chlorine derivatives, antibiotics and other antiseptic agents to rawhides curing.
