Description
Technical field
The present invention relates to the synthetic methods and application of a kind of macromolecule cation type bleach-activating, belong to fine chemistry industry neck
Domain.
Background technique
Hydrogen peroxide is a kind of industrial widely applied bleaching agent.In traditional hydrogen peroxide bleaching technique, peroxidating
Hydrogen usually works under the conditions of highly basic (sodium hydroxide or sodium carbonate is added in pH 11-12), high temperature (close to 100 DEG C), no
But it will cause huge energy consumption, but also will increase plant chimney stalk processing load；In addition, also will cause matrix (example to be floated
Serious damage such as: cotton fiber).
Bleach-activating is organic peroxide acid precursor, and it is anti-that peroxidating hydrolysis can occur in aqueous solution with hydrogen peroxide
It answers, generates peroxy acid.Compared with hydrogen peroxide, peroxy acid has higher activity, can effectively remove foreign pigment at low temperature.
Bleach-activating is originally developed for family and industrial washing, to overcome hydrogen peroxide (derived from sodium perborate or percarbonic acid
Sodium) (generally below 80 DEG C) the too low disadvantage of efficiency under the conditions of wash temperature.Tetraacetyl ethylene diamine (TAED) and nonanoyl oxygroup
Benzene sulfonic acid sodium salt (NOBS) is most common two kinds of bleach-activatings in family and industrial washing at present.This century first 10 years
In early days, researcher begin trying by TAED and NOBS activated hydrogen peroxide system be applied to high energy consumption, heavily contaminated weaving and
Paper pulp bleaching industry, it is intended to alleviate severe Energy situation and more stringent environmental requirement increasingly.However, the water solubility of TAED
It is poor, greatly limit its application in industrial bleaching；In addition, TAED activated hydrogen peroxide system is low in temperature
Bleaching efficiency under the conditions of 70 DEG C is not high.NOBS needs (pH > 10) application under alkaline condition, if pH is too low (in
Property), the peroxy acid of generation can continue that the lower diacyl peroxide of nucleophilic substitution generation activity occurs with NOBS, drop
Low bleaching efficiency.In recent years, research has found a kind of cationic bleach-activating N- [4- (triethyl ammonium methylene) benzoyl group]
Caprolactam chloride.The bleach-activating has excellent water solubility, and has to the electronegative material surface in surface certain
Affinity.
