| titleOfInvention | The preparation method of 3-bromo-N,N-dimethylaniline |
| abstract | The present invention relates to a preparation method of 3-bromo-N,N-dimethylaniline. Mesitylene is used as a reaction solvent to participate in the methylation reaction of trimethyl phosphate and m-bromoaniline to prepare 3-bromo-N, N-dimethylaniline. The preparation method of the invention avoids the harsh reaction conditions of the prior art while obtaining high-yield and high-quality products, has mild reaction conditions, high safety, high controllability, low pollution in the whole process, less three wastes, and side reactions less, the post-processing is simple, the product is easy to separate, the process operation is simple, the cost is low, and it is especially suitable for large-scale industrial production. |
