Walter Weizel "Ruprecht-Karls-Universität Heidelberg". He received his doctorate in physical chemistry at Heidelberg, under Max Trautz. He switched form chemistry to physics to work on the quantum mechanics of molecules as a fellow of the "Notgemeinschaft der Deutschen Wissenschaft" (NG; Emergency Association of German Science) at the "Universität Rostock". He completed his Habilitation in 1929. After Habilitation, Weizel worked briefly at "Badische Anilin- und Sodafabrik" (BASF, Baden Aniline and Soda Factory) at Ludwigshafen. Then, during 1931, he had a Rockefeller fellowship to the University of Chicago. From late in 1931, Weizel was an "ordentlicher Professor" (ordinarius professor) of theoretical physics at the
Aniline on the nitrogen is partially delocalized into the pi system of the benzene ring. Missing in such analysis is consideration of solvation. Aniline is, for example, more basic than ammonia in the gas phase, but ten thousand times less so in aqueous solution. Aniline reacts with acyl chlorides such as acetyl chloride to give amides. The amides formed from aniline are sometimes called anilides, for example CH-CO-NH-CH is acetanilide. At high temperatures aniline and carboxylic acids react to give the anilides. "N"-Methylation of aniline with methanol at elevated temperatures over acid catalysts gives "N"-methylaniline and dimethylaniline: "N"-Methylaniline and dimethylaniline are
