N-methylaniline is the main product in the N-alkyl aromatic amine series and an important intermediate in fine chemicals. Very versatile. my country’s first set of production equipment was built with assistance from the former Soviet Union in the 1950s. The products were mainly used to make explosive centralizers and were often used to blend straight-run gasoline. Since straight-run gasoline has more n-alkanes and a lower octane number, it is generally used in Therefore, some technicians use straight-run gasoline as the base oil for blended gasoline, and increase the octane number by adding N-methylaniline to achieve the goals of low investment and high efficiency.

Physical and chemical properties

N-methylaniline is a colorless oily liquid at room temperature. Soluble in ethanol, ether, and chloroform, insoluble in water, not easily lost by evaporation, but not conducive to distribution in the cylinders of multi-cylinder engines. It is stable in nature and does not decompose easily in air and dark environments. The main characteristics of blended gasoline with N-methylaniline antiknock agent are odor, high density, unstable unwashed gum, low olefin value, and the need for auxiliary antiknock agents such as MTBE and MMT.

Application

N-methylaniline is a fine chemical product with a wide range of uses. It is mainly used to make pesticides, dyes, dye intermediates, rubber additives and explosive stabilizers. It can also be used as a solvent and acid acceptor for organic synthesis. Chemicalbook intermediates, acid absorbers and solvents. In the dye industry, it is used in the production of cationic brilliant red FG, cationic pink B, reactive yellow-brown KGR, etc. It can also be used to increase the octane number of gasoline and organic synthesis, and can also be used as a solvent.
