Method for synthesizing bis(dimethylaminoethyl)ether under catalysis of metal catalyst

The invention discloses a method for synthesizing bis(dimethylaminoethyl)ether (BDMAEE) under the catalysis of a metal catalyst. The method comprises the following steps: preparing a metal oxide; then preparing the metal catalyst from the metal oxide; and with dimethylamine and dimethylaminoethoxyethanol as raw materials, preparing BDMAEE under the catalysis of the metal catalyst, wherein a main inorganic by-product is water, and produced organic by-products can be recycled through distillation and purification. The method provided by the invention has good economic benefits and overcomes the problem of environmental pollution of conventional BDMAEE production processes.
