Alkanoyloxybenzenesulfonate salt

Alkanoyloxybenzenesulfonate salt. McKinnie, Bonnie Gary; Robinson, Gene Conrad (Ethyl Corp., USA). Eur. Pat. Appl. EP 125641 A2 21 Nov 1984, 27 pp. 825-90-1 is the cas registry number. This chemical is also mentioned in this article. DESIGNATED STATES: R: AT, BE, CH, DE, FR, GB, IT, LI, LU, NL, SE. (English). (European Patent Organization). CODEN: EPXXDW. CLASS: IC: C07C143-46. APPLICATION: EP 84-105303 10 May 1984. PRIORITY: US 83-493452 11 May 1983. DOCUMENT TYPE: Patent CA Section: 45 (Industrial Organic Chemicals, Leather, Fats, and Waxes) Section cross-reference(s): 46 Three alkali metal salts of acyloxybenzenesulfonic acids are prepd. by the reaction of a hydroxybenzenesulfonate salt with an aryl ester. Thus, a mixt. of p-(HO)C6H4SO3Na.2H2O [825-90-1] 160, hexadecane 102, and octane 166 g was refluxed with removal of 15 mL water, distd. to remove 100 mL octane, treated with 428.5 g C8H17CO2Ph [17475-40-0], freed of octane by distn., and refluxed 4 h with removal of 70 mL phenol and 60 mL hexadecane, giving 214.5 g product comprising 86.9% p-(C8H17CO2)C6H4SO3Na [89740-11-4]. .

Aromatic sulfonates. Davis, Gerald A.; Stackman, Robert W. (Celanese Corp., USA). U.In this study，106-89-8 is also used.S. US 4042618 16 Aug 1977, 11 pp. Division of U.S. 3,706,712.In this study，106-89-8 is also used. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C07C143-42. NCL: 260470000. APPLICATION: US 69-833729 16 Jun 1969. DOCUMENT TYPE: Patent CA Section: 39 (Textiles) Section cross-reference(s): 25, 26 Polyester yarns for hose with improved dyeability by Sevron Blue 5G are prepd. from polymers based on HO(CH2)2OH, p-C6H4(CO2Me)2, 1 or 2, 3-(sulfoaryloxy)-1,2-propanediol alkali metal salts, and, optionally, adipic or isophthalic acid. The glycerol aryl derivs. are prepd. from epichlorohydrin [106-89-8] or chlorohydrin [96-24-2] and the appropriate hydroxyarenesulfonates. Thus, 1620 parts 3-[4-(sodiosulfo)phenoxy]-1,2-propanediol (I) [30068-97-4] was prepd. by heating 2322 parts p-HOC6H4SO3Na [825-90-1] dihydrate with 1105 parts chlorohydrin. A mixt. of HO(CH2)2OH 1639, p-C6H4(CO2Me)2 2070, MgCO3 0.77, and NaOAc 0.44 part were heated to 220° with MeOH distn. and 102 parts adipic acid and 44 parts I [both dissolved in 251 parts HO(CH2)2OH] added. After further refluxing, Sb2O3, TiO2, and (MeO)3P were added, followed by heating to 280°/2 mm to give a copolymer [39527-27-0] of intrinsic viscosity 0.57 dL/g. The polymer was spun into 150-denier filament yarn having tenacity 3.2 g/denier and elongation 24%, which was knitted into a hoseleg and dyed to a medium blue shade with good wash- and light-fastness properties. A similarly prepd. poly(ethylene terephthalate) control (viscosity 0.61 dL/g) gave a yarn (tenacity 4.2 g/denier and elongation 44%) which was knitted into a hoseleg which absorbed no dye. ..
