Production methodprocess of 4'-Hydroxypropiophenone powder

• The anhydrous aluminum trichloride is added to the carbon disulfide, stirring, dropping phenyl propionate, the reaction occurs immediately and releases hydrogen chloride, and the carbon disulfide is reflow due to the heat release of the reaction. After the drip is completed, the reaction mixture is heated and reflow for 2h until hydrogen chloride no longer escapes.
• The carbon disulfide is steamed and heated to 140-150℃ for 3h, and hydrogen chloride is released. The resulting resinoid substance is cooled, and hydrochloric acid and water are slowly added to decompose the double salt of aluminum. Place in the refrigerator overnight, strain and recrystallize the cake with methanol to obtain 4'-Hydroxypropiophenone
