-
Paragraph 0064-0075, (2019/04/26)
The invention relates to the technical field of synthesis of fine chemical intermediates, particularly to an ethyl N,N-dimethylaminoacrylate synthesis method, which comprises that ethyl acetate, carbon monoxide and dimethylamine are used as starting raw materials, and are subjected to a reaction under the action of a solid alkali catalyst to form the target product ethyl N,N-dimethylaminoacrylate,wherein the solid alkali catalyst is preferably a supported solid alkali catalyst. According to the present invention, the problems that the raw material source is difficult, the price is expensive,the process condition is harsh, the three-waste amount is high, the yield is low, the cost is high, the method is not suitable for industrial production and the like in the prior art are solved; and the synthesis method of the present invention has characteristics of convenient raw material source, low cost, environmentally-friendly reaction condition, substantially-reduced side-product, high total yield, high raw material utilization rate, low production cost and high product purity, and is suitable for large-scale industrial continuous production.

In the presence of Au nanoparticles supported on manganese oxide OMS-2 (Au/OMS-2), various kinds of β-heteroatom-substituted α,β-unsaturated ketones (heteroatom = N, O, S) can be synthesized through α,β-dehydrogenation of the corresponding saturated ketones using O2 (in air) as the oxidant. The catalysis of Au/OMS-2 is truly heterogeneous, and the catalyst can be reused.
