Runge, Friedlieb Ferdinand

Friedlieb Ferdinand Runge was a chemist attuned to the aesthetic side of chemistry. As chemist proper, he produced the first synthetic colour in 1833. As experimenter, his Romantically accented philosophy of nature and his Goethean morphological approach allowed him to generate glorious...

Runge s lack of reward for his discoveries and his management of the factory is detailed in Anft, Friedlieb Ferdinand Runge, pp. 31-40. The dispute, according to Anft, reveals the pernicious favouring of the administrator and businessman over the technical individual . 

Friedlieb Ferdinand Runge (Billwarder, nr. Hamburg, 8 February 1795-Oranienburg, 25 March 1867) was at first a pharmacist, then associate professor in Breslau (after a long residence in Paris), then in the Prussian Marine service in Berlin and Oranienburg. He published several technological and other papers, also on the motion of electrolytically polarised mercury, and... 

Since deep chemical peels are based on phenol-containing solutions, it seems that the history of this procedure starts at the moment of carbolic acid discovery in 1834 by the German chemist Friedlieb Ferdinand Runge. The name phenol had been coined in 1841 by Charles Frederick Gerhardt. Nowadays, phenol is prepared synthetically in a process that utilizes chlorobenzene as a starting point. 

Phenol was discovered in coal tar as early as 1834, by Friedlieb Ferdinand Runge. Coal tar remains an important source of phenol and its alkyl derivatives, even today. For a long time, phenol derived from coal tar was available in sufficient quantities to meet demand. However, requirements for phenol rose sharply with the use of picric acid as an explosive during the Boer War (1899-1902) and World War I, so that new means of production were developed. 

Pyrrole was discovered in 1834 by Friedlieb Ferdinand Runge in coal tar, where it is present in a concentration of less than 0.01%. Production from coal tar is, therefore, not economical. Pyrrole is synthesized by the reaction of furan with ammonia. Pyrrole is used in the production of polypyrrole and pharmaceuticals, such as the anti-inflammatory drug tolmetin. In tolmetin synthesis, the acidity of pyrrole is made use of. It is transformed into the potassium salt, which reacts with methyl chloride to form 1-methylpyrrole. The reaction of methylpyrrole with formaldehyde and dimethylamine produces the Mannich base, which is then quatemized... 

Quinoline was discovered in coal tar by Friedlieb Ferdinand Runge in 1834 it is present in concentrations of approximately 0.3%. Quinoline is recovered by extraction with sulfuric acid from the methylnaphthalene fraction of coal tar, followed by springing with ammonia and rectification of the crude base mixture. Quinoline can be synthesized by the Skraup method, by the reaction of aniline with glycerol (or acrolein produced from glycerol) and catalytic gas-phase reaction of aniline with acetaldehyde. Since the supply of the tar-derived material has been adequate for a long time, synthetic production is not warrented.
