Description

technical field

[0001] The invention relates to a catalyst for preparing anisole from phenol and dimethyl carbonate, belonging to the field of chemistry. Background technique

[0002] Anisole is an important organic chemical raw material, and has important applications in dyes, medicines, spices, resins, and synthetic fibers.

[0003] At present, anisole is mainly produced in industry with phenol and dimethyl sulfate as raw materials. Dimethyl sulfate is a highly toxic substance, which produces a large amount of highly toxic wastewater and solid waste. The environmental pollution is very serious, and some manufacturers have been forced to limit production. , Suspension of production has seriously affected the healthy development of downstream related industries. Dimethyl carbonate is a new green chemical raw material with low pollution and environmental friendliness. As a process of methylating reagent and phenol to synthesize anisole, it is harmless, non-toxic and non-poll...
