Preparation of 4-Aminobenzaldehyde: this chemical can be prepared by the oxidation and deoxidation of p-Nitrotoluene. Frist, please add 65% Ethanol and p-Nitrotoluene to the solution of Sodium polysulfide. The reaction will occur at temperature of 80-86 °C for 1.5 hours. Then retrieve Ethanol, and remove p-Amino toluene by steam distillation. Afterwards, please use Benzene to extract the reaction liquid. At last, you will obtain the product after steam distillation, cooling, filtration and drying.
Uses of 4-Aminobenzaldehyde: this chemical 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.
This reaction needs Toluene and Ethyl acηte at room temperature for 0.5 hour. The yield is 72 %.
When you are using this chemical, please be cautious about it as the following: it is irritating to eyes, respiratory system and skin. In case of contact with eyes, please rinse immediately with plenty of water and seek medical advice. And you should wear suitable protective clothing, gloves and eye/face protection.
