Oxone compounds

The triple salt is better known by the trademarks Caroat (Degussa), OXONE Monopersulfate Compound (Du Pont), and Curox (Laporte). It is also known as potassium caroate. It has been made on a commercial scale siace the 1950s, and the world market ia 1994 was several thousand tons. It is made commercially by Peroxid-Chemie (Germany), Degussa (Germany), Du Pont (United States), and Migas (Japan). In 1994, the United Kingdom price was J1.80/kg ( 2.67/kg). [Pg.95]

Nitroso compounds are formed selectively via the oxidation of a primary aromatic amine with Caro s acid [7722-86-3] (H2SO ) or Oxone (Du Pont trademark) monopersulfate compound (2KHSO KHSO K SO aniline black [13007-86-8] is obtained if the oxidation is carried out with salts of persulfiiric acid (31). Oxidation of aromatic amines to nitro compounds can be carried out with peroxytrifluoroacetic acid (32). Hydrogen peroxide with acetonitrile converts aniline in a methanol solution to azoxybenzene [495-48-7] (33), perborate in glacial acetic acid yields azobenzene [103-33-3] (34). [Pg.230]

The name 5-azaorotic acid should be given to allantoxanic (oxonic) acid but it is not yet commonly used. The elucidation of the correct structure of this compound was closely linked to the solution of the course of oxidation of uric acid mentioned earlier. [Pg.199]

Works on the oxidation of uric acid has unequivocally established the triazine structure > ° (9) of oxonic acid. This is further confirmed by the straightforward synthesis described by Piskala and Gut. ° The reaction of biuret (11) with potassium ethyloxalate yielded a potassium salt (24), that with ethyl oxamate, the amide of oxonic acid (25). Both these compounds were converted to 5-azauracil. An analogous reaction with diethyloxalate which should produce an ester of oxonic acid resulted in a mixture of urethane and parabanic acid, however. [Pg.200]

Phosphorothionates OP compounds containing thion groups (cf. organophos-phates that contain oxon groups). [Pg.333]

One shortcoming in many field studies is a failure to address adequately exposure to toxic transformation products. In efforts to manage time and cost constraints, the concentrations of parent materials and transformation products are often added together to produce a total toxic residue amount. However, it is more appropriate to evaluate individual transformation products as their toxicity may be significantly increased (e.g. active oxons) or decreased (e.g. dehalogenation or dealkylation products) relative to the parent compound. [Pg.940]

Aliphatic and aromatic primary amines are rapidly and efficiently oxidized to nitro compounds by dimethyldioxirane.111 Dimethyldioxirane is prepared by reaction of OXONE (DuPont trademark)-2KHS05-KHS04-K2S04 with buffered aqueous acetone.112... [Pg.20]

The one-pot conversions of oximes to gem-halonitro compounds have been achieved by using A(/V,/V.-trihalo-l,3,5-triazines,131 chloroperoxidase in the presence of hydrogen peroxide and potassium chloride,132 or commercial OXONE and sodium chloride.133 Of these methods, the case of OXONE may be the most convenient (Eq. 2.65). [Pg.23]

The simplest model compound is cyclohexene oxide III. Monomers IV, V and VII represent different aspects of the ester portion of I, while monomers VII and VIII reflect aspects of both the monomer I and the polymer which is formed by cationic ring-opening polymerization. Monomers IV-VII were prepared using a phase transfer catalyzed epoxidation based on the method of Venturello and D Aloisio (6) and employed previously in this laboratory (7). This method was not effective for the preparation of monomer VIII. In this specific case (equation 4), epoxidation using Oxone (potassium monoperoxysulfate) was employed. [Pg.86]

Method B for potentially acid-labile compounds TBA-Oxone (0.98 g, 0.6 mmol) and anhydrous Na2CO, (0.64 g, 0.6 mmol) suspended in CH,Cl2 (10 ml) are added to the sulphide (0.2 mmol) and the mixture is stirred at room temperature until all of the sulphide has been consumed. The mixture is diluted with Et20 (15 ml). The organic phase is separated, washed with aqueous NaOH (2M, 25 ml), H20 (25 ml), and brine (25 ml), dried (MgS04), and evaporated to yield the sulphone. [Pg.445]

Plant. Oat plants were grown in two soils treated with [ Ciphorate. Most of the residues remained bound to the soil. Less than 2% of the applied [ Ciphorate was recovered from the oat leaves. The major residues in soil were phorate and the corresponding oxon, sulfone, oxon sulfone, sulfoxide, and oxon sulfoxide (Fuhremann and Lichtenstein, 1980). These compounds were also found in asparagus tissue and soil treated with the insecticide (Szeto and Brown, 1982). [Pg.1605]

Soil. Ambrosi et al. (1977a) studied the persistence and metabolism of phosalone in both moist and flooded Matapeake loam and Monmouth fine sandy loam. Phosalone rapidly degraded (half-life 3-7 d) but mineralization to carbon dioxide accounted for only 10% of the loss. The primary degradative pathway proceeded by oxidation of phosalone to phosalone oxon. Subsequent cleavage of the 0,0-diethyl methyl phosphorodithioate linkage gave 6-chloro-2-benzoxazolinone. Although 2-amino-5-chlorophenol was not detected in this study, they postulated that the condensation of this compound yielded phenoxazinone. [Pg.1605]

Qilorpyrifos reacted with fi ee chlorine to form chlorpyrifos oxon, which is more toxic than the parent compound. Both compounds further hydrolyze to a more stable product, 3,5,6-trichloro-2-pyridinol [110]. [Pg.116]

Ozonation of organophosphorous pesticides led to the formation of oxon intermediates (diazooxon, methyl paraoxon, and paraoxon for diazinon, methyl parathion, and parathion, respectively) [116]. These compounds accumulated to a different extent as a function of the solution pH. [Pg.116]

Primary, secondary and tertiary aliphatic amines are efficiently converted to nitro compounds in 80-90 % yield with dimethyldioxirane, a reagent prepared from the reaction of oxone (2KHSO5-KHSO4-K2SO4) with buffered acetone. Dimethyldioxirane (DMDO) has been used for the synthesis of 1,3,5,7-tetranitroadamantane (71) from the corresponding tetraamine as the tetrahydrochloride salt (70) and is an improvement over the initial synthesis using permanganate anion (Table 1.7). ° Oxone is able to directly convert some aromatic amines into nitro compounds. [Pg.21]
