Schiff base metal manganese complex and preparation method and application thereof

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.

KINETICS AND MECHANISM OF BASE-CATALYZED CYCLIZATION OF SUBSTITUTED AMIDES AND NITRILES OF HYDANTOIC ACID

Rates of base-catalyzed cyclizations of 8 substituted derivatives of hydantoic acid amide type R3-NH(5)-CO(4)-NR2(3)-CH2(2)-CO(1)-NHR1 and 9 nitriles type R3-NH(5)-CO(4)-NR2(3)-CHR1(2)-CN have been measured in aqueous and methanolic media.The cyclization of the amides in aqueous medium is also accompanied by hydrolysis of the hydantoins formed.In some cases the hydrolysis rate constant is greater than the corresponding cyclization reaction rate constant.With the least reactive amides, the cyclization is also accompanied by hydrolysis of the amide group.The ra te of the cyclization reactions in water is higher than that in methanol (at the same concentration of the lyate ions) by the factor of 10 - 100.Substitution of hydrogen at 3 and 5 positions by methyl or phenyl groups causes an acceleration of the cyclization reaction, whereas a substitution in the amide group causes a considerable retardation.The greatest acceleration of the cyclization (by as much as 4 orders) is caused by introduction of phenyl group to the N(5) position, which is due to a substantial increase of concentration of the reactive anion.
