(5) embodiment
Below in conjunction with specific embodiment, the present invention is described further, but protection scope of the present invention is not limited in this:
The dyestuff characterizing take chemical formula in embodiment is the free acid form of compound.But it should be noted that, they are conventionally with the form of an alkali metal salt, and preferably the form of lithium salts, sodium salt or sylvite is prepared and separates, and is used for dyeing with the form of its salt.Similarly, in following examples, starting compound can free acid or with the form of an alkali metal salt for the synthesis of in.
Embodiment 1:
(1) after the 2-aniline sulfonic acid of diazotization: 17.3g is added to and stirs in 150mL water, be cooled to 0-5 ℃, add 12.5g31%(w/w) hydrochloric acid, maintain 0-5 ℃ and slowly drip 24.5g30%(w/w) sodium nitrite in aqueous solution, at this temperature, stir 1 hour, eliminate excessive Sodium Nitrite with thionamic acid, obtain the diazo liquid of 2-amino-Phenylsulfonic acid.
(2) diazotization: after the para-ester of 56.2g (to (beta-hydroxyethyl sulfone sulfate) aniline) is added to and is stirred in 150mL water, be cooled to 0-5 ℃, maintain 0-5 ℃ of Sodium Nitrite that slowly drips 21g31% hydrochloric acid and 48g30%, at this temperature, stir 1 hour, eliminate excessive Sodium Nitrite with thionamic acid, obtain the diazo liquid of para-ester.
(3) coupling: by 3 of 15.2g, 5-diaminobenzoic acid adds in 100mL water, after dissolving, joins the diazo liquid of step (1) in this lysate, and adjust pH 5.3-5.5 also controls temperature 5-8 ℃, and coupled reaction 3 hours, obtains coupling solution one time.
(4) coupling: step (2) is reacted to the para-ester diazo liquid obtaining and be added drop-wise to fast step (3) and react in the coupling solution obtaining, adjust pH 6.0-7.0 to control temperature be 5-10 ℃, coupled reaction 5 hours, obtain secondary coupling solution, drying, the dye composition (seeing Fig. 1 nuclear magnetic resonance map) of the hydrazone formula structure of main acquisition formula (I-1) free acid form, on this dyestuff, dyeing and weaving thing is yellow tone.
Spectrum elucidation: δ 3.71ppm, δ 4.03ppm are equivalent to 8 protons, for
In alkane hydrogen; For fragrant hydrogen, hydrazone formula is inhaled electrically and is declined, and therefore hydrazone formula base ortho-hydrogens shift value is less, should be the hydrogen of δ 7.43-7.54ppm, owing to being 3 hydrogen, showing to connect on sulfonic phenyl ring and has connected hydrazone formula nitrogen, conforms to structural formula.δ 9.90ppm, δ 10.21, δ 10.60, δ 11.30ppm are unimodal, show to exist the independent hydrogen of four different chemical environment, conform to the nitrogen hydrogen of four different positionss in structure.
Embodiment 2～4:
According to the preparation method described in embodiment 1 or similar method, different: to adopt respectively the arylamine in the arylamine 1, arylamine 2 alternative steps (1), step (2) of equimolar amount in table 1 to carry out diazotization, can make hydrazone formula dyestuff as shown in table 1, upper dyeing and weaving thing presents bright yellow.
Application Example:
At 60 ℃, respectively 100 grams of cotton fabrics are added in the dye bath of 1500 grams of 45g/L sodium-chlor and 2 grams of reactive dyestuffs that obtain according to embodiment 1～8.At this temperature, dye after 45 minutes, add the sodium carbonate solution of 20g/L, keep this temperature to dye again 45 minutes.Then, rinse product dyed thereby, soap 15 minutes with nonionic detergent, post rinse is also dry, records its basic dyeing behavior eigenwert in table 2:
Table 2: basic dyeing characteristic value S.E.R.F
In upper table:
S value represents the size of dyestuff to fiber affinity.S value is large, shows that dyestuff is large to the avidity of fiber, inhales look fast, but migration property meeting variation, easily washing property is poor to dye rear unconjugated dyestuff.
E value represents the degree of exhaustion of dyestuff.E value is large, represents that the clean absorption rate of dyestuff is high, and the utilization ratio of general remark dyestuff is high, and depth is good, and the pollution level of dyeing waste is little.
F value represents the degree of fixation of dyestuff.F value is large, illustrate covalent linkage reaction to occur and the dyestuff of set is many, and it is few that the dyestuff and the unreacted dyestuff that are hydrolyzed occur, and dye utilization rate is high.
The reactive height of R value representation dyestuff.R value is large, illustrates that dyestuff is strong with the ability that fiber generation covalent linkage reacts under alkaline condition, and speed of reaction is fast, but the too high aberration end to end that easily causes.
From above-mentioned table 1, reactive dyestuffs S value of the present invention and R value are moderate, illustrate that avidity and level-dyeing property are all good; E value and F value are large, illustrate that dyestuff depth is good, and degree of fixation is high, and dye utilization rate is high.
In addition, test by method definite in GB/T3921, GB/T3920 and GB/T14576 respectively that it is water-fastness, antifriction scrape along sweat proof-photorecombination colour fastness, the results are shown in Table 3:
Table 3: colour fastness
To sum up, hydrazone formula structure-activity dyestuff of the present invention, while being applied to dyeing, has preferably comprehensive dyeing behavior, and depth is good, degree of fixation is high, level-dyeing property is good, wet colour fastness is excellent.
