Abstract

5,6 - Dichloro - 1 - ethyl - 2 - methyl - 3 - (4 - sulphobutyl)benzimidazolium iodide is obtained as its sodium salt by heating an intimate mixture of 5,6-dichloro-1-ethyl-2-methyl-benzimidazole and sodium 4-iodobutane-sulphonate. 4-Iodobutane sulphonic acid is obtained as its sodium salt by refluxing sodium iodide with 1,4-butane sultone in methyl alcohol. Specifications 524,154, 524,554, 524,555, 541,589, 581,772, 654,690, 660,012 674,161 and 680,488 are referred to.ALSO:Carbocyanine dyes are referred to having the general formula:- <FORM:0871936/IV(c)/1> wherein R is an alkyl group of 1 to 4 carbon atoms, n is 1 or 2 and D is an alkylene group. R may be ethyl and D may be ethylene, trimethylene, tetramethylene or o -methyl-trimethylene. An example is given of the preparation of anhydro-5; 51; 6; 61-tetrachloro-1; 11-diethyl-3; 31-di (4-sulphobutyl)- benzimidazolocarbocyanine hydroxide by refluxing the sodium salt of 5; 6-dichloro- 1-ethyl- 3-(4-sulphobutyl) benzimidazolium iodide with chlorol alcoholate in ethanolic sodium. Specifications 524,154, 524,554, 524,555, 541,589, 581,772, 654,690, 660,012, 674,161 and 680,488 are referred to.
