AI Technical Summary

Problems solved by technology

However, various catalysts have corresponding shortcomings in this field. For example, the water solubility of metal phthalocyanine complexes is poor, and after the fabrics bleached by macrocyclic polyamine metal complexes are dyed, there will be large-scale decolorization after a period of time.
[0003] Most of the amino acid Schiff base complexes have biological activity and play an important role in the field of enzymatic catalysis. However, such complexes have problems such as high toxicity and low water solubility, which are not conducive to their promotion and use.

Abstract

The invention discloses a quaternized amino acid Schiff base metal coordination compound as well as a preparation method and application. Epoxy chloropropane and pentaerythritol are subjected to a reaction in a condition that sodium hydrate is used as a catalyst, so as to obtain a quaternized reagent TMPT (Trimethylolpropane Triacrylate); the quaternized reagent TMPT and 4-(diethylamino)salicylaldehyde are subjected to a reaction to obtain quaternized 4-(diethylamino)salicylaldehyde; afterwards, the quaternized 4-(diethylamino)salicylaldehyde and serine are subjected to a reaction, so as to obtain the quaternized amino acid Schiff base coordination compound; the coordination compounding is carried out by adopting a metallic salt and a ligand, so as to obtain the quaternized amino acid Schiff base metal coordination compound. The quaternized amino acid Schiff base metal coordination compound provided by the invention not only has better water solubility, but also can be used for obviously improving the bleachability of hydrogen peroxide, and can be used for the hydrogen peroxide to bleach a fabric at a low temperature.

Description

technical field [0001] The invention relates to the technical field of synthesis of textile printing and dyeing auxiliaries, in particular to a quaternized amino acid Schiff base metal complex, a preparation method and an application thereof. Background technique [0002] At present, fabric bleaching is usually carried out under high temperature and strong alkali conditions, resulting in a large amount of water and energy being wasted, which is increasingly inconsistent with the requirements of building a conservation-friendly and environmentally friendly society. Therefore, hydrogen peroxide low-temperature bleaching technology has received extensive attention. Enzyme-catalyzed reaction has the characteristics of high efficiency, specificity and mild conditions, and there have been many studies in the pulp bleaching industry. However, the sources of biological enzymes are limited, so using analog enzymes with similar or similar functions to biological enzymes for bleaching...
