Table is obtained a result thus: under 0.2% concentration, the novel asymmetric white dyes whiteness value of the present invention has all surpassed 91.5; Less than 0.4% o'clock, whiteness was to increase than higher enhancing rate in concentration; When concentration surpassed 0.6%, paper of whiteness changed very little, used dyeing behavior and had higher cost performance.
2. polycomponent mixing Compositional type white dyes
It is current development trend that the polycomponent white dyes mixes composite, has mentioned various preparation methods in many inventions.Polycomponent mixing Compositional type white dyes has adopted following design in the series of the present invention:
1) R
1And R
2Choose the Sulphanilic Acid residue of the hydrogen atom on the deaminize, R
3Mainly be selected from ethanol amido, diethylin, morpholinyl and anilino, R

3H and R
4The additional proportion of H is selected 1: 1.
2) adopt the synthesis step different with traditional synthetic route.Be that one step condensation takes place earlier for cyanuric chloride and Sulphanilic Acid, carry out two steps, three with DSD acid and diethanolamine successively again and go on foot the synthetic route of condensations.After carrying out one, two step condensation reactions, the chlorine atom is active identical on the triazine ring of secondary condensation product two ends, when adding R
3H and R
4When H carried out condensation, even the chlorine atom is substituted on the end triazine ring, the activity of chlorine atom did not reduce on the other end triazine ring, so the substitution reaction of two ends triazine ring has synchronism, congruency, so R
3H and R
4The addition sequence of H is very little to the scale influence of each component in the mixed type white dyes.After the three step condensations, obtained the mixed type white dyes of wishing.
Operation steps:
One step condensation: in 500ml there-necked flask (ice-water bath), add a certain amount of mixture of ice and water and cyanuric chloride, temperature maintenance is at 0～5 ℃, violent stirring is uniformly dispersed, adding waits the Sulphanilic Acid of CC molar weight, regulates pH about 20, is raised to certain 10 ℃ behind the reaction 25h;
Two step condensations: be elevated to 40-50 ℃ in the water bath with thermostatic control, add half the DSD acid of CC molar mass, regulate the pH value to about the 35-45, reaction 15-25h;
Three condensations: be warmed up to 75-85 ℃, the R of molar masss such as adding and CC
3H and R
4H (both ratios are 1: 1).Regulate the pH value to about the 75-85, reaction 2-3h.Reaction is finished after drying and is got solid product.
Synthetic product of the present invention is made up of two kinds of mutually a kind of asymmetrical type white dyess of symmetric form white dyes.Its product is to contain to comprise the mixture of array structure white dyes down.
By test, mix the Compositional type white dyes among the present invention and show better cost performance:
1) uv absorption property, fluorescent emission integrated intensity and the quantum yield that mixes the Compositional type white dyes be greater than the conventional fluorescent whitening agent, its test data such as following table:
2) carry out the tint applications test, test result such as following table with the step of asymmetrical type white dyes tint applications to mixing the Compositional type white dyes:
Test result shows that the mixed type white dyes plays composite addition, and cost performance is higher.Under 02% concentration, the whiteness value portion of other white dyess has surpassed 94.Less than 04% o'clock, whiteness was to increase than higher enhancing rate in concentration, and when concentration surpassed 0.4%, the paper whiteness changed very little, when reaching the 0.8% xanthochromic trend that occurs now and then.
3. quaternary white dyes
Most of triazines-DSD acids white dyes precipitates under acidic conditions easily.The sulfonic acid type white dyes of quaternary ammonium salinization is an amphoteric substance, and it has the activity of optical fluorescence whitening agent and positively charged ion auxiliary concurrently, improved its anti-strongly-acid, with the associativity and the fastness to washing of fiber, practicality improves greatly.
The present invention carries out following highway route design in conjunction with 1 synthetic method among the traditional preparation process method of quaternary amine and the present invention:
1) chlorine on bad and reactive tertiary amine with triazine just can obtain the quaternary white dyes.Tertiary amine of the present invention is chosen triethylamine or trolamine;
2) the present invention is set out by DSD acid and synthesizes quaternary amine type white dyes, and its one or two step condensation is with 2; Last chlorine atom on the triazine ring of two ends, after adding tertiary amine compound, quaternary ammonium reaction just takes place in the secondary condensation product, obtains quaternary amine type white dyes.
Operation steps: (with 2)
Synthetic product chemical equation of the present invention is as follows:
1) the quaternary white dyes is tested its data such as following table:
In contrast to the test data of the white dyes product of reference in 1 by above data, can draw: the uv absorption property of quaternary white dyes, fluorescent emission integrated intensity and fluorescence quantum yield be all less than the non-quaternary white dyes of tradition, simultaneously uv absorption property and fluorescent emission poor-performing.
2) to synthetic two kinds of quaternary ammonium salts white dyes and non-quaternary white dyes be respectively 7,5,3 in the pH value, the type white dyes is respectively in the pH value and tested its test data such as following table at 7,5,3,1 o'clock:
By the dyeing behavior of above test data comparative determination quaternary amine type and non-quaternary amine type white dyes, analyze its acid proof power, it is extremely shown in Figure 4 with change curve such as Figure of description Fig. 1 of pH value to observe its whitening effect.
Data and curve draw thus: along with the decline of pH value, precipitation appears in the water-soluble decline of non-quaternary amine type white dyes, causes the whiteness performance to descend greatly.And the quaternary white dyes is as amphoteric substance, and it has the character of positively charged ion auxiliary concurrently, and its acid resistance is strong, higher with the associativity and the fastness to washing of fiber, is adapted at the dyeing under the acidic conditions more.
