Abstract

The invention discloses a method for continuously decolorizing musk ketone by using active carbon fibers. The active carbon fibers are subjected to plasma treatment, so that the specific surface area of the active carbon fibers is increased, and the adsorption capacity of the active carbon fibers is improved. Through high-temperature oxygen oxidation, oxygen-containing functional groups are further increased on the surface of the active carbon fiber on the basis of plasma treatment, and the targeted adsorption performance of the active carbon fiber on polar molecules is improved. In the decolorizing process, standing waves are introduced, so that the fixing capacity of pigment molecules adsorbed in the active carbon fibers can be improved, the pigment molecules are not easy to desorb out, and the adsorption capacity of the active carbon fibers is increased.

Description

technical field [0001] The present invention relates to the technical field of decolorization of the present invention, and more particularly to a method for continuously decolorizing ketone musk with activated carbon fibers. Background technique [0002] Keto musk has an elegant, rich musk aroma, a slightly natural musk aroma, and a powdery aroma that is soft and long-lasting. It is used to prepare essence, its aroma quality is more elegant than xylene musk, and it is used as a fixative; it can be used to prepare cosmetic and soap essence; it can also be used together with methyl violet copper, cinnamyl alcohol, benzyl salicylate and other spices to prepare powder type fragrance. However, most ketone musk contains a certain degree of yellow, which affects its application range. SUMMARY OF THE INVENTION [0003] In view of this, the present invention provides a method for continuous decolorization of ketone musk with activated carbon fiber, which not only has good decolo...
