| titleOfInvention | A kind of method of one-step synthesis 2- amyl -2- cyclopentenone |
| abstract | The present invention provides a kind of method of one-step synthesis 2- amyl -2- cyclopentenone, it is characterised in that: under mixed gas atmosphere, the mixed liquor of valeraldehyde and cyclopentanone is added dropwise in the lye comprising composite catalyst, single step reaction synthesizes 2- amyl -2- cyclopentenone；The mixed gas is the mixed gas of nitrogen and hydrogen.The method of the present invention, one-step synthesis method 2- amyl -2- cyclopentenone, total recovery is high, and cost is relatively low for supplementary material, and in terms of valeraldehyde, the yield of conversion ratio 99.4-99.8%, selective 87.23-90.68%, 2- amyl -2- cyclopentenone is 87.05-90.5%；The composite catalyst that the present invention uses can be applied 25-40 times or more；The method of the present invention, by-product is few, and the product purity of preparation is high；The waste water of the method for the present invention, generation is less, environmental protection. |
