Product Description

p-Chloroacetophenone is a chemical reagent used in the synthesis of various pharmaceutically and biologically active compounds such as COX-2 inhibitors. Stable at room temperature in closed containers under normal storage and handling conditions.

Production methods: The reaction of chlorobenzene and acetic anhydride: to heat and stir the anhydrous aluminum chloride, the unhydrated disulphide and the dry chlorobenzene, and gradually drop into the anhydride in the boiling. After adding, stir back to 1h and recycle disulfide. When the reactants are cooled to room temperature, slowly pour into the crushed ice containing hydrochloric acid. The layer should be clear, if not clear, the hydrochloric acid should be added a little. Pour a small amount of benzene in the solution after extracting, collect oil layer, water layer with benzene extraction time, extract and reservoir merged, with about 15% of the caustic wash to acid, and then washed with water to neutral, drying, vacuum distillation, collect the coarse fraction, the frozen after 48 h, the separation of mother liquor, will melt crystallization is the finished product. Yield of 83.1%.


Used as a fluorescent whitening agent, pharmaceutical and intermediate materials
