Compound NaOCl

N—Fe(IV)Por complexes. Oxo iron(IV) porphyrin cation radical complexes, [O—Fe(IV)Por ], are important intermediates in oxygen atom transfer reactions. Compound I of the enzymes catalase and peroxidase have this formulation, as does the active intermediate in the catalytic cycle of cytochrome P Q. Similar intermediates are invoked in the extensively investigated hydroxylations and epoxidations of hydrocarbon substrates cataly2ed by iron porphyrins in the presence of such oxidizing agents as iodosylbenzene, NaOCl, peroxides, and air. 

Calcium hypochlorite is the principal commercial soHd hypochlorite it is produced on a large scale and marketed as a 65—70% product containing sodium chloride and water as the main diluents. A product with a significantly higher available chlorine, av CI2, (75—80%) has been introduced by Olin. Calcium hypochlorite is also manufactured to a smaller extent as a hemibasic compound (- 60% av Cl ) and to a lesser extent in the form of bleaching powder (- 35% av CI2). Lithium hypochlorite is produced on a small scale and is sold as a 35% assay product for specialty appHcations. Small amounts of NaOCl ate employed in the manufacture of crystalline chlorinated ttisodium phosphate [56802-99-4]. 

The most stable solid hypochlorites are those of Li, Ca, Sr and Ba (see below). NaOCl has only poor stability and cannot be isolated pure KOCl is known only in solution, Mg yields a basic hypochlorite and impure Ag and Zn hypochlorites have been reported. Hydrated salts are also known. Solid, yellow, hydrated hypobromites Na0Br.xH20 (x = 5, 7) and K0Br.3H20 can be crystallized from solutions obtained by adding Br2 to cold cone solutions of MOH but the compounds decompose above 0°C. No solid metal hypoiodites have yet been isolated. 

Song and Roh investigated the epoxidation of compounds such as 2,2-dimethylchromene with a chiral Mn (salen) complex (Jacobsen catalyst) in a mixture of [BMIM][PFg] and CH2CI2 (1 4 v/v), using NaOCl as the oxidant (Scheme 5.2-12) [62]. 

New interesting applications have been in the epoxidation of difficult olefin compounds (including hexafluoropropene) with NaOCl, side-chain chlorination of substituted toluenes, diazotization of pentafluoroaniline, polymerization with free radicals, etc. 

Liquid household bleach is generally a 5% solution of sodium hypochlorite (NaOCl). Ammonia cleansers—including general household cleansers, wax removers, glass and window cleaners, and oven cleaners — are aqueous solutions of 5-10% ammonia, NH3. Mixing bleach with cleansers containing ammonia leads to the formation of a family of potentially toxic compounds known as chloramines. These toxic gases have acrid fumes that can bum mucous membranes. Scented bleaches can mask one s natural ability to detect these harmful fumes. 

Arrange the following compounds in the order of increasing pH of a 0.1 M solution of each NaOCl, NaHC02, Na2C03, NaN3, and NaHS. 

Oxidation of (alkenylthio)thiophenecarboxaldehyde oxime 350 (R = allyl) by NaOCl gives the nitrile oxide, which cyclizes to thieno[2,3-h]thiocino[4,5-c] isoxazole 351. However, isomeric 350 (R = isopropenyl), under the same conditions, is converted to the unusual product, thieno 2,3-/ thiocin 352. In both reactions, cyclodimerization products of nitrile oxides are also obtained. Structures of compounds 350 (R = isopropenyl) and 352 have been studied by X-ray diffraction analysis (411). 

Rather than the expected [3 + 2] cycloaddition, a novel ene-like cycloisomerization occurs on deprotonation of allyltrimethylsilyl-oxime compounds, when the j3-sp2 carbon atom of the allyltrimethylsilyl moiety is tethered to the oxime unit. The resulting nitrile oxide group serves as an enophile, and the final cyclized product still has two functional groups suitable for further manipulations. Thus, ene-like cycloisomerization of allyltrimethylsilyl-oxime 375 with NaOCl in CH2CI2 gives 82% of cyclized product 376 (423). See also Reference 424. 

The acidity of aqueous NaOCl (10%, 50 ml, 80 mmol) containing TBA-HS04 (0.2 g, 0.59 mmol) is adjusted to pH 8 with cone. HCl and then added with stirring to the phenolic compound (18 mmol) in CHC13 or EtOAc (50 ml). The mixture is stirred until... 

The surface of a wool hair is covered by keratin sheds, which cause a distinct tendency to shrinkage and formation of felts. This behavior is usually undesirable and thus an antifelt finishing is the most important treatment during the processing of woolen textiles. One of the most important standard procedures, the Hercosett finish, is based on the oxidative treatment of wool by application of compounds that release chlorine. Examples for applied chemicals are NaOCl, CI2 gas, and dichloroisocyanuric acid (DCCA) [14]. 

Chloro derivatives of 4,5-dichloropyridazin-3(2//)-one and 4-chloro-5-methoxypyridazin-3(2//)-one have been synthesized by treating the pyridazinones with NaOCl in acetic acid <2005S1136>. These pyridazinones can be used as reagents for the chlorination of active methylene compounds (see Section 8.01.8.2). 

Chlorine Residual Extraction. A 400-mL solution of distilled water containing 70 ppm of sodium bicarbonate, 120 ppm of calcium sulfate, and 47 ppm of calcium chloride was extracted under typical operational conditions. Similarly, a solution containing all of these materials plus a 2-ppm chlorine residual (prepared with NaOCl) was extracted. Analysis of the U-tube traps, feedstock, and raffinate solutions in each case (blank and chlorine residual samples) showed that no new chlorinated compounds were formed by the presence of a chlorine residual. 

Benzotriazole can be chlorinated at the N(l) position by NaOCl (85H(23)2225). 1-Chlorobenzotriazole - a rather stable crystalline compound that has found application in organic synthesis as a selective chlorinating reagent and mild oxidant. A-Fluorination of benzotriazole with cesium fluoroxysulfate gives 1-fluorobenzotriazole in 25% yield (91T7447).
