| titleOfInvention | Preparation method and application of salen Cu (II) catalyst |
| abstract | The invention provides a preparation method of a salen Cu (II) catalyst, which is characterized by extracting racemic cyclohexanediamine p-toluenesulfonate from filtrate generated by synthesizing (S, S) -monosalt serving as an intermediate of a (S, S) -salen catalyst ligand, and reacting the racemic cyclohexanediamine p-toluenesulfonate with 3, 5-di-tert-butylsalicylaldehyde and copper acetate in a single solvent by a one-pot method to obtain the racemic salen Cu (II) catalyst. According to the invention, the salen Cu (II) catalyst is synthesized by using the waste liquid generated by synthesizing the (S, S) -monosalt serving as the intermediate of the (S, S) -salen catalyst ligand, so that waste is changed into valuable, the environmental pressure is reduced, and the application is widened. The invention also discloses an application of the catalyst, which is particularly used for degrading cyanide-containing wastewater, the cyanide breaking process is simple, the cyanide breaking effect is good, the salen Cu (II) catalyst is easy to recover, the cost is low, the large-scale production is easy, and the catalyst has wide application value. |
