2-Methylimidazole
1. Product Description:
2-Methylimidazole is an organic compound that is structurally related to imidazole with the chemical formula CH3C3H2N2H. It is a white or colorless solid that is highly soluble in polar organic solvents. It is a precursor to a range of drugs and is a ligand in coordination chemistry.
Overview:
2-methylimidazole, also known as dimethylimidazole, is a white acicular crystal or crystalline powder at room temperature. Molecular weight 82.11. Melting point 145 ~ 146℃. Boiling point 267℃. Can sublimate. Flash point 160℃. Insoluble in ether, cold benzene, soluble in water, alcohol, ketones. Irritates the skin and mucous membranes. Mice transoral LD501400mg/kg. 2-methylimidazole is an intermediate in the production of the trichomoniasis resistant pesticide Medrol (Metanidazole). It is also the curing agent and curing accelerator of epoxy resin and other resins, which occupies a special position in the amine curing agent. When it is used as the medium temperature curing agent of epoxy resin, it can be used alone. After heat treatment in a short time, the curing substance with high heat deformation temperature can be prepared. However, it is mainly used as a curing accelerator for powder molding and powder coating. It can be obtained by dehydrogenation of 2-methylimidazoline.
Preparation method:
1, using glyoxal, acetaldehyde and ammonia as raw materials, 2-methylimidazole crude product is generated after reaction, and then sublimation refining, the finished product can be prepared.
2, using ethylenediamine and acetonitrile as raw materials, the reaction is carried out in the presence of sulfur to generate imidazoline, and then in the presence of nickel catalyst, dehydrogenation at 200℃, 2-methylimidazole can be prepared.
3, can be prepared by the reaction of glyoxal and methylamine in the presence of formaldehyde.
