The main uses of N-methylaniline
General
N-Methylaniline (CAS 100-61-8) is an aromatic amine widely used in fuel additive formulations as a non-metallic anti-knock agent.
It enhances fuel performance by delaying auto-ignition and stabilizing combustion reactions, making it a key component in modern octane booster systems.
N-methylaniline ZX-GL-03 is a colorless to reddish-brown oily flammable liquid. Its melting point is -57℃, boiling point is 196.25℃, relative density is 0.9891, and refractive index is 1.5684. It is slightly soluble in water, but has good solubility in ethanol, ether and chloroform.
N-methylaniline ZX-GL-03, as a high-cleanliness gasoline anti-knock additive, does not contain lead, iron, manganese, sulfur and other restricted elements in gasoline or oxygenated compounds. It is suitable for blending various types of gasoline. It can be directly added and mixed evenly, which is convenient, stable and reliable
N-methylaniline ZX-GL-03 is an organic compound with the chemical formula C7H9N. It is a colorless to reddish-brown oily liquid, slightly soluble in water, and soluble in ethanol, ether, and chloroform. It is mainly used as an intermediate in organic synthesis, an acid absorbent, and a solvent. It is used in the dye industry for the production of cationic brilliant red 5GN, cationic peach red FG, cationic peach red B, reactive yellow brown KGR, reactive yellow brown KGR, reactive brilliant blue X-BR, reactive orange K-2RL, acid blue BR, etc.

→ Reduced risk of spark plug fouling
3. Cost-Effective Fuel Upgrading
Low dosage delivers strong octane improvement.
→ Upgrade low-grade gasoline
→ Reduce blending cost
4. Stable Blending Performance
Good solubility and compatibility with gasoline.
→ Easy integration into fuel systems
→ Reliable performance in different formulations
4. Applications & Business Scenarios
Fuel Blending & Refining

Preparation:
The production methods of N-methylaniline ZX-GL-03 are diverse. One of them is to mix aniline vapor with methyl ether and react it at 230-295℃ under the action of an activated alumina catalyst. Another method is to generate crude N-methylaniline ZX-GL-03by reacting aniline and methanol in the presence of a lead-zinc-chromium catalyst, and then obtain the finished product by distillation to remove methanol, water, aniline and N, N-methylaniline ZX-GL-03. In addition, in the laboratory, dimethyl sulfate can also be used as a methylating agent to prepare N-methylaniline. The specific operation is to add dimethyl sulfate to a mixture of aniline and water with a concentration of less than 10%, stir for 1 hour, then add 30% sodium hydroxide solution, let it stand and separate the upper organic phase, and extract the lower layer with benzene. After recovering benzene from the extract, the oily substance obtained combines with the organic phase, which is a mixture of aniline, N-methylaniline ZX-GL-03 and N, n-dimethylaniline. The mixture was treated with sulfuric acid to form sulfate crystals of aniline, which were filtered out. N, N-dimethylaniline was converted to N-methylaniline through the reaction with acetic anhydride. The content of N-methylaniline in industrial products is as high as over 98%, and each ton of the product consumes 1,200 kilograms of aniline and 700 kilograms of methanol.
methylaniline ZX-GL-03 is mainly used as an intermediate for pesticides, dyes, pharmaceuticals, organic synthesis raw materials, and can also serve as an anti-knock agent for gasoline, an acid absorber, a solvent and a stabilizer, etc.
The N-methylaniline ZX-GL-03 produced by our company is not only an environmentally friendly intermediate and active agent in the fields of medicine and pesticides, but also can be used as an anti-explosion additive for non-metallic gasoline by taking advantage of its chemical bond energy characteristics and excellent octane number > 300. The free hydrogen decomposed by the heating of this additive in the engine combines with the active free radicals in the gasoline to form relatively stable molecules This reduces the free radicals produced by thermal radiation, lowers the occurrence of the pre-combustion point, enables the gasoline to burn fully and evenly in the combustion chamber, increases power, eliminates carbon deposits, and saves energy and improves efficiency.
