N-Methylaniline Usage And Synthesis

Description	N-Methylaniline is a yellow to light brown oily liquid with a weak, ammonia-like odor. Turns reddishbrown if left standing. The odor threshold is 1.7 ppm. Molecular weight= 107.17; Specific gravity (H2O:1)= 0.99;Boiling point=195.6℃; Freezing/Melting point=57.2℃; Vapor pressure= 0.3 mmHg at 20℃; Flash point=79.4℃. Hazard Identification (based on NFPA-704 M Rating System): Health 2, Flammability 2, Reactivity 0. Practically insoluble in water.
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]. References: [1] Zhiqiang Wang, Chenghua Deng, Xiao Liu, Wenmin Wang, Highly efficient conversion of CO2 into N-formamides catalyzed by a noble-metal-free aluminum-based MOF under mild conditions, 2023, 52, 11163-11167.

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.
