Abstract:  Synthesis of anisole with DMC and phenol over SiO₂ supported K₂CO₃, KBr, and KF catalyst was studied under continuous condition. Effects of the reaction conditions such as reaction temperature, reaction space velocity, ratio of reactants and catalyst loading amount, were investigated. The optimized reaction conditions were found for KF/SiO₂. The ratio of DMC to phenol is 2∶1(mol ratio), MHSV is 2h^-1 and reaction temperature is at 250℃, yield of anisole is as high as 93.93%, and anisole selectivity is high to 98.19%. And the catalyst activity was still very high after 16h of reaction. Therefore, the new reaction technology introduced in the present study is a practical environmentally benign anisole synthesis process.
