Reaction Conditions:
with copper;copper(l) chloride;sodium hydroxide in ethanol at 175; for 4 h;Autoclave;Inert atmosphere;Industrial scale;Reagent/catalyst;
Steps:
1 Example 1
In a 4800L autoclave, 1700 kg of 50% sodium hydroxide solution was added, 1850 kg of an ethanol solution containing 1000 kg of 3-chloro-4-methylaniline was added, 50 kg of cuprous chloride and 15 kg of copper powder were added, and the reaction vessel was sealed and replaced with nitrogen 5 times. Warm up to 175°C, incubate for 4 hours, sample and analyze. After passing the test, cool down. Ethanol is recovered under reduced pressure, filtered into an 8000L tank, neutralized by adding 1450 kg of industrial hydrochloric acid to weak acidity, extracted with 2000 L of ethyl acetate and extracted three times, and ethyl acetate is recovered under reduced pressure. , get crude. The crude product was added with 1000 kg of ethanol, heated to 60° C., and 50 kg of activated carbon was added. After stirring for 1 hour, the mixture was filtered and cooled to 5° C. to obtain 707 kg of a product with a yield of 85.36% and a purity of 99.8%.
