Study on the Synthesis Method of 2-Hydroxy-4-Alkoxybenzophenones

The physical quality and common synthesis method of 2-hydroxy-4-alkoxybenzophenones were simply introduced in this paper. At the same time the synthesis method of 2-hydroxy-4-alkoxybenzophenones, which included the solvent method and the phase transferring method were discussed in detail nowadays. By using dihexadecyldimethylammonium as phase transferring agent, 2-hydroxy-4-alkoxybenzophenones was synthesized at the normal temperature and pressure, and the complicated purification processing would be cared, and the yield of product was higher. It believed that this method would be greatly functioned in organic synthesis and fine industry.
