Description
Technical Field

Background
Formamide is an important basic chemical raw material and is widely applied to the fields of manufacturing medicines, plastics, dyes, spices and the like. At present, the industrial preparation method of formamide mainly adopts a one-step method and a two-step method, wherein the one-step method is prepared by mixing carbon monoxide and ammonia gas, taking strong base sodium methoxide as a catalyst and carrying out one-step chemical combination under the conditions of high temperature and high pressure (0.8-1.7MPa, 348-; the two-step method is that carbon monoxide and methanol are taken as raw materials, strong alkali sodium methoxide is taken as a catalyst, the raw materials are combined into methyl formate by adopting the reaction conditions of high temperature and high pressure (10-30MPa, 353-. The two-step method is mainly adopted to prepare formamide in industrial production, and the method can effectively solve the problem of separation of the catalyst and the formamide. However, both methods require the use of caustic, strong bases, fossil energy derived carbon monoxide and harsh reaction conditions. Not only are these production methods not sustainable on the raw materials, but the large amount of greenhouse gases produced further worsens the environment. Meanwhile, the harsh reaction conditions inevitably lead to the configuration of expensive production facilities in factories, which results in the increase of product cost.
The development of an electrosynthesis method which takes biomass-derived methanol as a raw material and can be operated at room temperature and room pressure can effectively overcome the defects, thereby having important practical significance. Meanwhile, the site of electric synthesis can adopt a distributed mode, which can cut down the product transportation expense and the time cost. In addition, electrosynthesis utilizes electron transfer to complete the conversion of substances, so that the use of toxic and harmful reducing agents and oxidizing agents such as strong acid, strong alkali and the like can be effectively avoided. Moreover, another important chemical raw material hydrogen can be obtained while the formamide is prepared by electrosynthesis. Therefore, the electrochemical method is a green and sustainable formamide production method.
