Use: This product is feed intermediate growth promoting agent for two of sulfamethoxazole, also the curing agent for epoxy resin and other resin. As the temperature in the epoxy resin solid by agent, can be used alone, but is mainly used as a curing agent for powder forming and powder coating. Are hygroscopic, soluble in water, alcohol, insoluble in benzene. Irritant and corrosive to the skin and mucous membrane. This product is used in the synthesis of metronidazole, dimetridazole, also the bad epoxy resin curing agent.

Production method by 2- methyl imidazoline and eliminate the dehydrogenation. 2- methyl imidazoline heating melting (melting point of 107 DEG C), carefully add the activity of nickel, heating to 200-210 Deg. C reaction of 2h. Cooling to 150 DEG C, dissolved in water, while hot press, separation of active nickel, concentrating the filtrate to the temperature of 140 DEG C, discharging cooling to obtain the 2- methyl imidazole. Produce a purity of greater than or equal to 98% of the product by this method, the 1t product consumption ethylenediamine (95%) 1095kg, acetonitrile 975kg. A better approach is to use B two formaldehyde and formaldehyde as raw material.
