Purpose: the goods is drugs metronidazole and forage growth of dimethyl azole intermediates, and curing agent of epoxy resin and other resin. As WenGu in the agent of epoxy resin, can be used alone, but is mainly used as curing catalyst powder molding and powder coating. Has the water absorbability, soluble in water, alcohol, soluble in benzene. Are irritating to the skin, and mucosa and corrosion resistance. The synthesis of this product is used for metronidazole, dimetridazole, and bad oxygen resin curing agent.

Methods of production by 2 - methyl imidazoline eliminate dehydrogenation. Will be 2 - methyl imidazoline heating melting, melting point 107 ℃), you add active nickel, heat up to 200-210 ℃ reaction for 2 h. Cooled to below 150 ℃, and water dissolving, hot pressure filtration, separation of active nickel, condensed the filtrate to temperature above 140 ℃, feeding the cooling for a quick 2 - methyl imidazole. With the purity of 98% or higher products, 1 t products consumption ethylenediamine (95%) of 1095 kg, 975 kg of acetonitrile. A better method is to use glyoxal and formaldehyde as raw material. 

Packing: 25 kg cardboard barrels
