2-aminopyridine, colorless leaf or large crystal. The melting point is 57-58 C, boiling point 204 C, 104-106 C (2.67kPa), flash point 92 C. Soluble in water, alcohol, benzene, ether and hot petroleum ether. Taste bitter, have anaesthetic effect. Can be sublimated. Used in organic synthesis, can be used as intermediates and chemical reagents for drugs and dyes. Usually, in the presence of solvents, sodium amide is reacted with pyridine. Hydrogen escaped from the reaction and sodium derivatives of aminopyridine were produced, which were hydrolyzed to form free aminopyridine. Operation Example 1: Sodium Amino was added to dry toluene, heated and refluxed, pyridine was added to nitrogen at the same time, and refluxed for 6 hours. At the end of the reaction, cooling to 20, nitrogen, slowly adding water, adding, heating to 60-70, the toluene layer was separated by static separation, the water layer was kept at 60-70, the toluene was extracted twice with toluene, and the toluene was recovered by vacuum extraction. The distillate at 100-140 (8kPa) was collected and 2-aminopyridine was obtained.
