Geometry and spectra of substituted anilines was written by Klevens, H. B.;Platt, J. R.. And the article was included in Journal of the American Chemical Society in 1949.Safety of 2-Chloro-N,N-dimethylaniline This article mentions the following:
The absorption curves for N,N-dimethylaniline and its derivatives, o-methyl, o,o’-dimethyl-, p-methyl, o-fluoro-, o-chloro-, o-bromodimethylaniline have been determined to 1700 A. Four characteristic regions of absorption were found near 1800, 2100, 2500, and 3000 A. The effect of steric inhibition of resonance on these absorption spectra was studied. Total oscillator strengths were shown to decrease almost linearly with the van der Waals’ radius of the group substituted in the o-position. The min. angle of twist of the -N(CH3)2 group with respect to the ring was estimated from the van der Waals’ radius of each crowding group. The oscillator strengths of the different bands varied with cosine-square of the angle. With certain simple assumptions, purely spectroscopic calculations were made of the angle of twist and of the variation of the N-C6H5 bond order and bond distance. The 3 strong aniline bands transform into the 3 alkylbenzene bands with respect to both intensity and position as the angle of twist approaches 90°. In the experiment, the researchers used many compounds, for example, 2-Chloro-N,N-dimethylaniline (cas: 698-01-1Safety of 2-Chloro-N,N-dimethylaniline).
2-Chloro-N,N-dimethylaniline (cas: 698-01-1) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Safety of 2-Chloro-N,N-dimethylaniline
