Reaction Conditions:
with potassium hydroxide in water at 150; for 24 h;Large scale;
Steps:
1.8; 2.8; 3.8; 4.8
Put 790 kg of m-difluorobenzene, 265 kg of methanol, 520 kg of potassium hydroxide and water into the kettle together, and heat the reactor to 150 for 24 hours,After the reaction, the temperature is lowered and put into the acidification kettle, and it is acidified by passing hydrogen fluoride,After extracting with 300 kg of toluene three times, the extraction layer and the oil layer were combined.After concentrated rectification, 866.5kg m-fluoroanisole was obtained.
