Products Description of Monomethylaniline CAS#100-61-8
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 the aid of the former Soviet Union in the 1950s. The products are mainly used to make explosive centralizers and are often used to blend straight-run Chemicalbook 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.
