| N-Methylaniline Usage And Synthesis |
| Chemical Properties | N-Methylaniline is a yellow to light brown oily liquid with a weak, ammonia-like odor. soluble in ethanol, ether, chloroform, slightly soluble in water. Turns reddishbrown if left standing. |
| Physical properties | Colorless to yellow to pale brown liquid with a faint, ammonia-like odor. Odor threshold concentration is 1.7 ppm (quoted, Amoore and Hautala, 1983). |
| Uses | N-Methylaniline is used as a solvent and in organic synthesis. It is used in the production of cationic brilliant red FG, cationic pink B, reactive yellow brown KGR, etc. in the dye industry. N-methylaniline is an intermediate in the synthesis of the insecticide buprofezin and the herbicide mefenacet. |
| Uses | N-methylaniline was used as raw material, and metal-organic skeleton material CAU-10pydc was used as catalyst to catalyze the reaction of CO2 with n-methylaniline to produce N-methyl-N-phenylformamide in mild conditions and green solvent acetonitrile[1]. Poly (N-methylaniline) (PNMA) was prepared by the electrooxidation of N-methylaniline in acidic aqueous solution. PNMA prepared in acidic aqueous solution with different organic solvents and anions had different conductivity. Such as the experimental group added acetonitrile, N, N-dimethylformamide and dimethylsulfoxide, and the experimental group which adding dimethylsulfoxide had the strongest conductivity[2].

| Preparation | N-methylaniline was synthesized by the reaction of aniline with dimethyl sulfate. Dimethyl sulfate was added dropwise to the mixed solution of aniline and water below 10°C, stirred for 1 h, and then added dropwise with 30% sodium hydroxide solution. The upper layer is the organic phase, and the lower layer is extracted with benzene. After the benzene is recovered from the extract, the obtained oil Chemicalbook-like substance is combined with the organic phase to obtain a mixture of aniline, N-methylaniline and N,N-dimethylaniline. The mixture was treated with sulfuric acid, and the aniline formed sulfate crystals which were filtered off. N,N-dimethylaniline can be converted to N-methylaniline by the following reaction. |
| Application | N-Methylaniline (NMA) was used in the preparation of self-assembled poly(N-methylaniline)-lignosulfonate (PNMA-LS) composite spheres with reactive silver-ion adsorbability. NMA was also used in electrodeposition of poly(N-methylaniline) (PNMA) coatings on a steel disc electrode using potentiodynamic, potentiostatic and galvanostatic techniques. |
| Definition | ChEBI: N-methylaniline is a methylaniline that is aniline carrying a methyl substituent at the nitrogen atom. It is a phenylalkylamine, a secondary amine and a methylaniline. It derives from an aniline. |
