3-Amino-p-anisanilide - Uses and synthesis methods
Production method
method 1 is a commonly used method in current production. Using o-nitroanisole as raw material, the product is obtained by chloromethylation, hydrolysis, oxidation, acyl chlorination, condensation, and reduction..
This method has long process route, long production cycle and low product yield.
method 2 is the latest research method. Using p-chlorobenzoic acid as raw material, the product is obtained by methoxylation, nitration, condensation and reduction. This method has a short process route, high product yield and low cost..
adding 46.8g p-chlorobenzoic acid, 250mL methanol and 12g auxiliary TR-300 into the reactor, refluxing for 10h to obtain 41.5g p-methoxybenzoic acid. Add it into a nitrocer, add 166g of dichloroethane and 0.5g of sulfuric acid (98%) at the same time, add 19g of nitric acid (98%) dropwise at 45 ℃, add it within 3h, continue the heat preservation reaction for 2h, and obtain 52.7g of nitrification product. Add it into the condensate, add 200mL of solvent and 40mL of aniline at the same time, raise the temperature to (98±2)℃, add 30mL of thionyl chloride dropwise (added within 30min), continue the heat preservation reaction for 4h, and obtain 70.0g of condensation product. Add it into the reducer, add 350mL sodium hydrosulfide solution (30%) at the same time, raise the temperature to (80±2)℃ for 15h, and obtain 51.8g of the final product.
