4-Aminobenzaldehyde Chemical Properties,Uses,Production
Description
4-Aminobenzaldehyde can be made into polymer with a certain conductivity and corrosion resistance, and the combination of stainless steel is better than the epoxy resin. It can be used as intermediate of pharmaceutical and dye. It is also used in organic synthesis. Additionally, it can react with Carbonyl dichloride to get 4-Formylphenyl isocyanate.
Chemical Properties
Yellow crystalline powder. Melting point 71-72℃. Soluble in alcohol, benzene, insoluble in water, very easy to polymerize.
Uses
4-Aminobenzaldehyde (p-aminobenzaldehyde) is a useful synthetic reagent and monomer that can be used to synthesize monoazo dyes and photocurable ion exchange resins. 4-Aminobenzaldehyde is also a corrosion inhibitor of metals.
Preparation
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.
