The low-temperature imitation enzyme oxidation catalyst technology is a new technology developed in the chemical industry in the mid-1990s. Its principle is to imitate laccase protein macromolecules through chemical synthesisof supramolecules, as a catalyst for low-temperature oxidation reactions, due to its participation in chemical reactions. It is not consumed by itself, so it does not need to be like a low-temperature activator. It must be added in a stoichiometric molar ratio with hydrogen peroxide, so the amount is less, only the amount of ppm (parts per million) can play a better catalytic effect in the water bath. It only changes the course of the chemical reaction of hydrogen peroxide. On the other hand, due to the special design of its molecule, it has a certain selectivity to the reaction substrate.
Therefore, the low-temperature imitation enzyme oxidation catalyst can preferentially oxidize the carbon-carbon double bonds in the lignin molecule. The function of the dyeing and finishing process is to shorten the hydrogen peroxide bleaching reaction time and reduce the activation energy of the hydrogen peroxide chemical reaction ( Temperature), so it can be expected to be used in dyeing and finishing low-temperature bleaching and low-temperature soaping processes.
