Product Description

 

4- aminopyridine, white crystal. Soluble in water, slightly soluble in ethanol, insoluble in ether and benzene, naphtha and petroleum. It is an intermediate in the synthesis of antibiotic drugs.

 

The pyridine with hydrogen peroxide, and phthalic anhydride into phthalates, with dilute hydrochloric acid decomposition into N- oxidation of pyridine hydrochloride. N- oxidation of pyridine hydrochloride was prepared by nitration of N- oxidation of -4- nitro pyridine. N- oxidation of -4- nitro pyridine was reduced by 4-. 1gN- oxidation of -4- nitro pyridine (melting point 159 DEG C) dissolved in 30ml acetic acid, adding 2.2g iron powder, the reaction began immediately after the addition of heat preservation 1h in the 100%, cool. Add about 50ml diluted water, with 30% sodium hydroxide solution and transferred into a strong alkaline, extracted with ether for 3 times, each time 100ml. Combined with ether extract, dried with anhydrous potassium carbonate. After distillation of ether, 4- was obtained by vacuum distillation. The crude product was recrystallized from benzene or toluene petroleum ether mixed solvent, and 0.6g white needle like crystal 4- was obtained. The yield was 90%.

 

Flammability hazard characteristics:Open fire; high heat emitting toxic nitrogen oxides.

Storage characteristics:Low temperature drying in the storeroom; separate from oxidant, acid and food additives.

 

Safety phrases:irCauses burns.ritating substance. Irritating to eyes, respiratory system and skin. Avoid contact with skin and eyes.In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.Wear suitable protective clothing, gloves and eye/face protection.Highly flammable.
