| titleOfInvention | Absorption and refining method for high-purity methylacrolein |
| abstract | The invention belongs to the field of fine chemicals and chemical intermediates, and particularly discloses an absorption and refining method for high-purity methylacrolein. The invention provides a methylacrolein product which is prepared through two-step rectification by taking alkane containing six to eight carbon atoms as an absorbent for absorbing MA, and the content of the methylacrolein product is 99.5wt%, and the moisture content of the methylacrolein product is less than 0.1wt%. The method utilizes the characteristics of weak polarity of six to eight carbon atoms and the mutual solubility of water, the high-purity methylacrolein has higher absorption efficiency as an absorbent, the moisture content in absorption liquid is only about 0.5wt%, the burden of dehydration in the follow-up rectification operation can be greatly lightened, and the energy consumption can be saved. The absorption and refining method is simple in technological process, low in cost, and the methylacrolein is high in purity, low in the content of water and other impurities, and low in energy consumption, and can meet the application situation having high requirement on the quality of the methylacrolein. |
