| dc.description.abstract | Edinger in 1908 reported in the German journal, Berichte der Deutschen Chemicen Gesellschaft , that he had prepared 8, mercapto, quinoline su1fonic acid with phosphorour pentachloride, thus obtaining the acid chloride of the sulfonic acid. The acid chloride he reduced with stannous chloride in a hydrochloric acid solution, and obtained the tin double salt of 8, mercapto quinoline. The free mercaptan was obtained by its extraction with ether from an alkaline solution. This paper is a description of the results obtained by its author when he attempted to duplicate Edinger's results, starting, however, with the preparation of quinoline, then preparing the sulfonic acid, the acid chloride, and finally the mercaptan. It was, also, hoped to be able to prepare the mercaptan by making 8, nitro, quinoline and reducing this to the amino compound, then diazotizing and adding potassium acid sulfide. The author was, however, successful only to the point of roughly identifying the 8, amino quinoline. [From introductory section] | en_US |
