Paragraph 0011; 0020, (2016/10/09)
The invention discloses a Schiff base metal manganese complex and a preparation method and application thereof.The method includes the steps of making salicylaldehyde and aniline react to obtain N-phenyl salicylaldehyde imine, making N-phenyl salicylaldehyde imine react with sulfamic acid and sodium carbonate with urea as the catalyst to obtain sulfo salicylic aldehyde, making sulfo salicylic aldehyde react with cyanide urea to obtain sulfo salicylic aldehyde condensation cyanide urea ligand, and coordinating ligand with metal manganese salt to obtain the Schiff base metal manganese complex.Sulfo salicylic aldehyde condensation cyanide urea ligand obtained through the technical scheme has excellent water solubility; the metal manganese complex obtained by coordinating ligand with metal manganese salt has high capacity for catalyzing peroxide hydrogen decomposition and producing many bleaching activity components; the complex further contains amido bonds or like amido bonds and cyano groups, so hydrogen peroxide decomposition can be accelerated to produce bleaching activity substances; due to cyano groups of short carbon chains, peroxide hydrogen decomposition can be easily catalyzed by the Schiff base metal manganese complex, the complex can be applied for bleaching peroxide hydrogen of fabric at low temperature, and the processed fabric has the advantages of being high in whiteness and excellent in capillary effect.
