CAS 826-81-3 8-Hydroxyquinaldine Price With Good Quality
8-hydroxyquinoline, white prismatic crystal. The melting point is 74 degrees, and the boiling point is 266-270 degrees. Soluble in hot alcohols, ethyl ether and benzene, insoluble in water. It can evaporate with steam and sublimate at 100 degrees centigrade. With phenol odor. It was obtained from the reaction of O aminophenol with croton aldehyde. The mixture of ortho aminophenol and ortho nitrophenol was added to hydrochloric acid. Add croton aldehyde to agitation. Heat 6h and lay overnight. The reaction o-nitrophenol was evaporated by steam distillation and weakly alkaline was obtained by adding Sodium Hydroxide solution to the residual steam. Then saturated with powdered carbonyl, 8-hydroxyquinadine was distilled by steam distillation. The crude product was decompressed and recrystallized with ethanol.
