N-Methylation of aniline with methanol at elevated temperatures over acid catalysts gives N-methylaniline and N,N-dimethylaniline: C 6 H 5 NH 2 + 2 CH 3 OH → C 6 H 5 N(CH 3) 2 + 2H 2 O. N-Methylaniline and N,N-dimethylaniline are colorless liquids with boiling points of 193–195 °C and 192 °C, respectively. These derivatives are of ...
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

The term nitroaniline in chemistry refers to a derivative of aniline (C 6 H 5 NH 2) containing a nitro group (—NO 2) There are three simple nitroanilines of formula C 6 H 4 (NH 2)(NO 2) which differ only in the position of the nitro group: 2-Nitroaniline; 3-Nitroaniline; 4-Nitroaniline
o-Toluidine is absorbed through inhalation and dermal contact as well as from the gastrointestinal tract. [19] [13] [20] [21]The metabolism of o-toluidine involves many competing activating and deactivating pathways, including N-acetylation, N-oxidation, and N-hydroxylation, and ring oxidation.
