Sodium benzene sulfonic acid

From sodium benzene sulfonate and chlorosulfonic acid. Rodionov, Bull. soc. chim. (4) 39, 305 (1926). [Pg.120]

For many years phenol was made on a large industrial scale from the substitution reaction of benzene sulfonic acid with sodium hydroxide. This produced sodium sulfite as a by-product. Production and disposal of this material, contaminated with aromatic compounds, on a large scale contributed to the poor economics of the process, which has now been replaced by the much more atom economic cumene route (see Chapter 2, Schemes 2.2 and 2.3). [Pg.27]

Tyrer A process for making phenol by first sulfonating benzene. Benzene vapor was passed through hot sulfuric acid the excess of benzene served to remove the water formed in the reaction. The benzene sulfonic acid was then hydrolyzed by fusion with sodium hydroxide. Invented by D. Tyrer in 1916. See also Dennis-Bull. [Pg.276]

Rh/19 (n=1,2,3,6) catalysts were used in the hydroformylation of 1-octene in the presence of conventional tensides such as the sodium salt of the dodecyl-benzene sulfonic acid (0.5 wt.%) in an 1-octene/nonane/methanol/water (60/34/50/ 56) mixture.121 With Rh/19 (n=6) the TOF achieved was 28 h. 1,21... [Pg.146]

Sulfonation of the detergent alkylate gives exclusively the 4-dodecy I benzene-sulfonic acids, which with sodium hydroxide form water-soluble dodecylben-zenesulfonates ... [Pg.1057]

You can prepare phenols in large quantities by the pyrolysis of the sodium salt of benzene sulfonic acid, by the Dow process, and by the air oxidation of cumene. Each of these processes is described below. You can also prepare small amounts of phenol by the peroxide oxidation of phenylboronic acid and the hydrolysis of diazonium salts. [Pg.58]

In this process, benzene sulfonic acid is reacted with aqueous sodium hydroxide. The resulting salt is mixed with solid sodium hydroxide and fused at a high temperature. The product of this reaction is sodium phenoxide, which is acidified with aqueous acid to yield phenol. [Pg.59]

Sulfonic acids and sulfonate salts contain the -S03H and -SO) groups, respectively, attached to a hydrocarbon moiety. The structural formulas of benzene sulfonic acids and of sodium 1 -(p-sulfophenyl)decane, a biodegradable detergent surfactant, are shown in Figure 1.19. The common sulfonic acids are water-soluble strong acids that lose virtually all ionizable H+ in aqueous solution. They are used commercially to hydrolyze fat and oil esters to produce fatty acids and glycerol used in chemical synthesis. [Pg.52]

To a solution of 199 parts of morphinane sodium in 900 parts of methanol was added a solution of 60 parts of benzene sulfonic acid methylethyl ester. The mixture was stirred at heating to give the ethylmorphine. [Pg.1515]

The more efficient route via cumene has superceded the fusion of benzene sulfonic acid with caustic soda for the manufacture of phenol, and the hydrolysis of chlorobenzene to phenol requires far more drastic conditions and is no longer competitive. Ethylene chlorohydrin can be hydrolyzed to glycol with aqueous sodium carbonate. [Pg.614]

Sodium softeners are used to treated RO influent water to remove soluble hardness (calcium, magnesium, barium, and strontium) that can form scale on RO membranes. Once known as sodium zeolite softeners, zeolites have been replaced with synthetic plastic resin beads. For sodium softeners, these resin beads are strongly acidic cation (SAC) polystyrene resin in the sodium form. The active group is benzene sulfonic acid, in the sodium, not free acid, form. Figure 8.12 shows styrene-divinylbenzene gel cation resin. Equation 8.4 shows the softening reaction for calcium exchange ... [Pg.164]

Methyl orange. Similar studies were made with the sodium salt of dimethylamino-azo-benzene sulfonic acid. The transformation started after the addition of 0.5-0.6 c.c. of 0.1 N HC1.[H+] = 2.2 X 10-4 or pH 3.66, and pOH of 8.54. The dissociation of this indicator too increases with temperature. [Pg.195]

Other studies in 2000 by Drew et al. reported that it is very difficult to spin fibers of PANI complexed to sulfonated polystyrene (PANFSPS), even when solutions containing sodium chloride and dodecyl benzene sulfonic acid sodium salt were used to lower the surface tension and thereby enhance electrospinning [16,17]. However, PANFSPS nanofibers can be produced by adding a carrier polymer such as PEO, polyacrylonitrile, or polyurethane. Also reported was the use of electrostatically layered sulfonated polystyrene as a template for the surface polymerization of conjugated polymers in their conducting form. Enzymatic synthesis of PANI and a copolymer of pyrrole and PEDOT was done on electrospun nanofiber... [Pg.169]

Phenol can also be produced by fusing the sodium salt of benzene sulfonic acid NaOH at 320°C, which leads to the formation of sodium phenate, sodium sulfite, and water. Saturation with CO2 yields phenol from the sodium phenate. [Pg.953]
