Chemische Eigenschaften
Yellow crystalline powder. Melting point 71-72℃. Soluble in alcohol, benzene, insoluble in water, very easy to polymerize.synthetische
4-aminobenzaldehyde is obtained from p-nitrotoluene by oxidation, reduction, sodium sulfide, and sodium hydroxide dissolved in water, filtration, and filtrate heated to 68 ° C to add sulfur powder, at 98 ° C reaction for 18min to get more sodium sulfide solution. Add 65% ethanol and p-nitrotoluene, reaction at 80-86 ℃ for 1.5h, recovery of ethanol, and steam distillation to remove by-products p-aminotoluene. The reaction solution is extracted with benzene, distilled by water vapor, cooled, filtered, and dried to obtain the finished product.Synthesis Reference(s)
