Ethanone, 1-(3-hydroxyphenyl)- - Production method
It is obtained by the reaction of m-aminoacetophenone and sodium nitrite. Add water and concentrated sulfuric acid into the reaction pot, add m-aminoacetophenone under stirring, and then add sodium nitrite aqueous solution dropwise under cooling, keep the temperature at 8-10 ℃, slowly raise the temperature to above 90 ℃ after adding, and continue stirring for 1h. The solid is precipitated by cooling, filtered, and the obtained crude product is recrystallized with hot water to obtain m-hydroxyacetophenone. 65% yield.
