Abstract

874,077. Organic salts. KODAK Ltd. July 30, 1957 [Dec. 10, 1956], No. 24205/57. Class 2(3). [Also in Groups IV(a) and XX] 3,6,9,12,15,18,21,24 - Octoxahexacosane - 1, 26-bis(methane sulphonate) is prepared by adding methane sulphonyl chloride to a chilled solution of nona-ethylene glycol in pyridine. By heating the product cautiously below 95‹C. with pyridine, 3,6,9,12,15,18,21,24-octoxahexacosane-1,26-bis(pyridinium methane sulphonate is obtained. This may be treated with sodium perchlorate in ethanol to give the corresponding pyridinium perchlorate. Polypropoxypropyl - α, # - bis(pyridinium methane sulphonate) (about 6 isopropoxy units) is prepared by adding methane sulphonyl chloride to a chilled solution of polypropylene glycol in pyridine and refluxing the bis (methane-sulphonate) so obtained with dry pyridine. Octa-ethoxyethyl-bis(trimethyl ammonium perchlorate) is obtained by stirring the bis (methyl sulphonate) of polyethylene glycol with alcoholic trimethylamine and adding sodium perchlorate in acetone to the product dissolved in methanol, p - t-Octylphenoxypolyethoxyethylpyridinium methane sulphonate is prepared by adding methane sulphonyl chloride to a chilled solution of p-t-octylphenoxytetra-ethoxyethanol and triethylamine in dry ether and heating the product with pyridine. Products having an average of 6.5, 8.5 or 11.5 ethoxy groups in the chain are similarly prepared. 3, 6, 9, 12, 15, 18, 21, 24 - Octoxahexacosane-1,26- bis(lauryl methyl sulphonium methane sulphonate) is prepared by refluxing the bis (methane sulphonate) of nona-ethylene glycol with dodecyl methyl sulphide in ethanol. 3,6,9, 12,15,18,21,24 - Octoxahexacosane 1,26 - bis (ethyl methyl sulphonium methane sulphonate), tetraethoxyethyl-bis(dimethyl sulphonium perchlorate) and p-t-octylphenoxy-tetraethoxyethyl-dimethyl sulphonium p-toluene sulphonate are prepared similarly. Sodium p-t-octylphenoxy-polyethoxyethylsulphate (12 ethoxy units) is obtained by adding chlorosulphonic acid to p-t-C 8 H 17 -C 6 H 4 - (O-CH 2 CH 2 ) 12 OH in dichloromethane while bubbling in a stream of nitrogen. Specifications 235,211, 524,040, 524,154, 524,554, 524,555, 531,246, 531,312, 541,589, 545,448, 547,064, 562,205, 586,211, 595,314, 598,174, 598,657, 627,814, 636,140, 649,660, 664,580, 680,474, 680,488, 680,593, 682,355, 733,119, 737,012, 737,103, 738,134, 738,957, 748,750, 752,030, 755,369, 757,653, 791,219, 814,823, 815,075, 874,082, and U.S.A. Specifications 1,623,499, 1,969,479, 2,410,689, 2,618,641 and 2,875,059 are referred to.
