Diphenyl oxide sulfonate

In the first step a rubbery polymer latex is prepared by emulsion polymerization of styrene and butadiene, the styrene being in an amount of 25%. Divinylbenzene is added as crosslinking agent in an amount of 1%. Diphenyl oxide sulfonate is used as emulsifier in aqueous solution and sodium formaldehyde sulfoxylate acts as a buffer in order to reach a pH of 4. As radical initiator, cumene hydroperoxide is used and the polymerization is conducted 70°C for 9 h. The end of the reaction period is detected as no further pressure drop is observed due to the consumption of butadiene.

Malik presented data [27] on the detergency of C12 and C13.6 SMEs via a modified Gardner Straight Line Washability Test [39]. The test solutions consisted of 0.6% of the test surfactant and 0.12% tetrapotassium pyrophosphate in 140 ppm as CaCOj water at 25°C. The C12 SME gave equivalent performance compared to decyl and branched dodecyl diphenyl oxide disulfonates. The Cl3.6 SME slightly outperformed the Cl2 SME but was not quite as good as the C8-10, 5-mole ethoxylated phosphate ester that was also included. Both SMEs contained the analog sulfonated fatty-acid sodium salts as secondary snrfactants. 

Monochlorobenzene. The largest use for monochlorobenzene, accounting for about 40 percent of the consumption, is in the production of chloronitrobenzenes. p-Nitro-chlorobenzene (NCR) is converted into p-phenylenediamines for use as antioxidants in rubber processing. A smaller use for NCR is in the synthesis the pain reliever acetaminophen. ort/io-Nitrochlorobenzene is a raw material for producing insecticides and several azo pigments. A large number of dyes also can be derived from either chlorobenzene or nitro-chlorobenzene. About 25 percent of the monochlorobenzene is used as a solvent for pesticide formulation and in MDI processing. The manufacture of diphenyl oxide, for heat transfer fluids, and phenylphenols, for disinfectants, consumes another 22 percent. About 8 percent is used to make dichloro-diphenylsulfone, an intermediate in the manufacture of sulfone polymers.

Sulfonation has been used to change some characteristics of blends. Poly(2,6-diphenyl-l,4-phenylene oxide) and polystyrene are immiscible. However, when the polymers were functionalized by sulfonation, even though they remained immiscible when blended, the functionalization increased interfacial interactions and resulted in improved properties (65). In the case of DMPPO and poly(ethyl acrylate) the originally immiscible blends showed increased miscibility with sulfonation (66). 

SuIfona.tlon, Sulfonation is a common reaction with dialkyl sulfates, either by slow decomposition on heating with the release of SO or by attack at the sulfur end of the O—S bond (63). Reaction products are usually the dimethyl ether, methanol, sulfonic acid, and methyl sulfonates, corresponding to both routes. Reactive aromatics are commonly those with higher reactivity to electrophilic substitution at temperatures > 100° C. Tn phenylamine, diphenylmethylamine, anisole, and diphenyl ether exhibit ring sulfonation at 150—160°C, 140°C, 155—160°C, and 180—190°C, respectively, but diphenyl ketone and benzyl methyl ether do not react up to 190°C. Diphenyl amine methylates and then sulfonates. Catalysis of sulfonation of anthraquinone by dimethyl sulfate occurs with thaHium(III) oxide or mercury(II) oxide at 170°C. Alkyl interchange also gives sulfation. 

In contrast to thiazoles, certain isothiazoles and benzisothiazoles have been directly oxidized to sulfoxides and sulfones. 4,5-Diphenyl-l,2,3-thiadiazole is converted by peracid into the trioxide (146). Although 1,2,5-thiadiazole 1,1-dioxides are known, they cannot be prepared in good yield by direct oxidation, which usually gives sulfate ion analogous to the results obtained with 1,2,4- and 1,3,4-thiadiazoles (68AHC 9)107). 

The 2,2 -bis(phenylthiomethyl) dispiroketal (dispoke) derivative is cleaved by oxidation to the sulfone, followed by treatment with LiN(TMS)2. The related bromo and iodo derivatives are cleaved reductively with LDBB (lithium 4,4 -di- -butylbiphenylide) or by elimination with the P4- -butylphosphazene base and acid hydrolysis of the enol ether. The 2,2-diphenyl dispiroketal is cleaved with FeCl3 (CH2CI2, rt, overnight)." The dimethyl dispiroketal is cleaved with TFA, and the allyl derivative is cleaved by ozonolysis followed by elimination. ... 

Catechin-immobilizing polymer particles were prepared by laccase-catalyzed oxidation of catechin in the presence of amine-containing porous polymer particles. The resulting particles showed good scavenging activity toward stable free l,l-diphenyl-2-picryl-hydrazyl radical and 2,2 -azinobis(3-ethylbenzothiazoline-6-sulfonate) radical cation. These particles may be applied for packed column systems to remove radical species such as reactive oxygen closely related to various diseases. 

Similar to the thermal rearrangements discussed in the previous subsection, the base-catalyzed rearrangements of cyclic four-membered sulfones to five-membered sulfinates have also been reported. For example, Dodson and coworkers have observed the rearrangement of cis- and trans-2,4-diphenylthiethane 1,1 dioxides to cis- and trans-3, 5-diphenyl-1,2-oxathiolane (2,3)-cis-2-oxides, respectively (equation 35), on treatment with t-butoxymagnesium bromide, which is stereospecific with respect to the phenyl group but stereoselective with respect to the oxygen atoms on sulfur. 

The overall transformation is the conversion of the carbon-sulfur bonds bond to a carbon-carbon double bond. The original procedure involved halogenation of a sulfide, followed by oxidation to the sulfone. Recently, the preferred method has reversed the order of the steps. After the oxidation, which is normally done with a peroxy acid, halogenation is done under basic conditions by use CBr2F2 or related polyhalomethanes for the halogen transfer step.92 This method was used, for example, to synthesize 1,8-diphenyl-1,3,5,7-octatetraene.

Similar to nitrogen compounds, electron-rich sulfur compounds, such as the sulfides, with the lone pair of electrons on the sulfur atom, are oxidized to sulfoxides and, further, to sulfones by the H202/titanosilicate sytem (218,232, 233). Table XXXI (232) illustrates typical conversions and product selectivities for various sulfides for the reactions catalyzed by TS-1. Bulky sulfides such as alkyl, phenyl sulfides are relatively unreactive because of their steric exclusion from the pores of TS-1. Diphenyl sulfide could not be oxidized at all. As the diffusivity and, hence, the conversion of the sulfide decreases, the further oxidation of the primary product (sulfoxide) becomes more competitive, leading to increased formation of the corresponding sulfone (Table XXXI) ... 

Plant. In plants, fonofos is oxidized to the phosphonothioate (Hartley and Kidd, 1987). Oat plants were grown in two soils treated with [ C]fonofos. Most of the residues remained bound to the soil. Less than 2% of the applied [ C]fonofos was recovered from the oat leaves. Metabolites identified in both soils and leaves were methyl phenyl sulfone, 2-, 3- and 4-hydroyxymethyl phenyl sulfone, thiophenol, diphenyl disulfide, and fonofos oxon (Fuhremann and Lichtenstein, 1980 Lichtenstein et al., 1982).
