Reaction Conditions:
with hydrogenchloride in methanol;Reflux;Time;
Steps:
1; 3
Add all the coupling filter cakes into 4500 parts of methanol, stir for 0.5 hours, then add 90 parts of 32% hydrochloric acid, then raise the temperature and reflux for 3 hours. The temperature was lowered and filtered to obtain a filter cake, which was beaten with an aqueous solution of sodium carbonate and then filtered to obtain 240 parts of 4-amino-4'-nitro-3-methylazobenzene (dry weight) with a liquid chromatography content of 98.82%.
