N-Methylaniline is an aniline derivative. It is an organic compound with the chemical formula C6H5NH(CH3). The substance exists as a colorless or slightly yellow viscous liquid and turns brown when exposed to air. The chemical is insoluble in water. It is used as a latent and coupling solvent and is also used as an intermediate for dyes, agrochemicals and other organic products manufacturing. N-Methylaniline is a principal component of MMA (monomethylaniline), an antiknock agent, used to increase the octane number, more effective than Methyl tert-butyl ether. Usually added to gasoline in concentrations around 1.3% mass.

Brief manufacture process:

Aniline and methanol to form crude N-methylaniline under the action of copper-zinc-chromium catalyst and then distilling off methanol, water, aniline and N, N-dimethylaniline to obtain crude N-methylaniline and then vacuum distillation to obtain product.
Aniline and dimethyl sulfate reaction.
Dimethyl sulphate was added dropwise to a mixture of aniline and water at a temperature below 10 ° C. After stirring for 1 h, 30% sodium hydroxide solution was added dropwise. The mixture of aniline, N-methylaniline and N, N-dimethylaniline is obtained by combining the organic phase with the oil obtained by recovering the benzene from the extract. Treatment of the mixture with sulfuric acid, so that aniline sulfate formation filter out. N, N-dimethylaniline can be converted to N-methylaniline by the following reaction.
