| titleOfInvention | Preparation method of 1,3, 5-trimethoxybenzene |
| abstract | The invention relates to a preparation method of 1,3, 5-trimethoxy benzene, which is characterized by comprising the following steps: reacting a reaction substrate with sodium methoxide under the catalysis of cuprous halide; the reaction substrate is selected from one of 1,3, 5-trichlorobenzene, 1,3, 5-tribromobenzene, 1,3, 5-triiodobenzene, 1,3, 5-trimethylsulfonyl benzene and 1,3, 5-tri (trifluoromethanesulfonyl) benzene. The solvent for the reaction is one or two selected from N, N-dimethyl amide, N-diethyl amide, methanol, ethanol, isopropanol and dimethyl sulfoxide. The method has simple and convenient operation and good reproducibility, and the prepared finished product has stable quality and high purity. |
