Uses 4 -Hydroxyacetophenone has been used as ketone component in the preparation of 1-aryl-3-phenethylamino-1-propanone hydrochlorides, potential cytotoxic agents, via Mannich reactions. Uses 4′-Hydroxyacetophenone has been used as ketone component in the preparation of 1-aryl-3-phenethylamino-1-propanone hydrochlorides, potential cytotoxic agents, via Mannich reactions. Uses p-Hydroxyacetophenone is widely used in medicine, cosmetics and industrial fields. It is a natural plant extract, which naturally exists in the stems and leaves of the Compositae plant, Artemisia annua, the roots of plants such as Artemisia annua, Rhododendron, and Panax ginseng. It has a good effect on yellow eyes caused by diseases such as hepatitis, and also has a good auxiliary effect on yellow eyes caused by various reasons. Due to its weak molecular activity, high temperature resistance, melting point of 95-97 °C and boiling point of 296 °C, it is widely used in various liquid pharmaceuticals and can prolong the shelf life of other active ingredients under high temperature conditions. It has no harm to human skin and is the safest high-temperature auxiliary active stabilizer in the pharmaceutical industry. Preparation Preparation by Fries rearrangement of phenyl acetate with Lewis acids aluminium chloride in nitrobenzene at 20–25° or at 50–60° in chlorobenzene between 45° and 65°, sealed tube and subjected to high power microwave irradiation for 2 min only (36%) in nitroethane at 60° (44%) in carbon disulfide at 45° (40%) in petroleum ether at 50° (20%) but between 130° and 175° (40–60%) aluminium chloride–sodium chloride mixture at 240–250° (10%) boron trifluoride at 90° (56%) scandium tris(trifluoromethanesulfonate), in nitromethane, at 50° (39%) titanium tetrachloride at 90–100° (34%) ferric chloride at 65° (25%) zinc chloride at 125° (8%) hydrofluoric acid, between 20° and 100° (94%) polyphosphoric acid, between 20° and 100° (69%) (50–53%)(44%) Nafion-XR 500, sulfonic acid type at 100° ZSM-5, in sulfolane, at 180° (28%) H-ZSM-5 at 400° or at 210° (6%) H-Nu-2 at 170° (15%) HY (Si/Al = 3) or fluorided alumina (Al2O3-F; 3 % wt.
