Abstract
The invention discloses azo type heterocyclic ring disperse dye, a preparation method of the azo type heterocyclic ring disperse dye, and the use of the azo type heterocyclic ring disperse dye. The azo type heterocyclic ring disperse dye is shown as formula (I), wherein each group is defined in the specification; and the azo type heterocyclic ring disperse dye provided by the invention can be independently used or can be mixed with the other disperse dye, can be used for dyeing and printing dacrons and blended fabrics, and is good in dyeing uniformity, friction resistance, light resistance, and good in sublimation fastness.
Description
One technical field
The present invention relates to a kind of azo type heterocyclic dispersed dye and preparation method thereof, relate to a class with 3-amino-5-nitro-2, the 1-benzisothiazole is the blue disperse dye of diazo component, belongs to the chemical material preparing technical field.
Two background technologies
Disperse Blue-56 number, the blue dyes as the low temperature modification dyestuff uses is characterized by even dyeing, but price is high, sewage is many when preparing.Dyestuff of the present invention has overcome above-mentioned shortcoming, has kept equally the advantage of even dyeing.
Three summary of the invention
The object of the present invention is to provide a kind of azo type heterocyclic dispersed dye and preparation method thereof.
The technical solution that realizes the object of the invention is: a kind of azo type heterocyclic dispersed dye, it is characterized in that this dye structure formula suc as formula shown in (I),

Wherein concrete structure is as follows:
A kind of azo type heterocyclic dispersed dye of the present invention can be as the dyeing of terylene and BLENDED FABRIC.
A kind of azo type heterocyclic dispersed dye of the present invention can use with other dispersed dye colorant match.
Four embodiments
Below in conjunction with specific embodiment the present invention is further described, these embodiment only are clear open the present invention, but protection scope of the present invention is not limited in this.
Embodiment 1
With 19.5 gram 3-amino-5-nitros-2, the 1-benzothiazole is dissolved in the 50mL sulfuric acid, and in 0.102 mole of nitrosyl sulfuric acid of 10-15 ℃ of dropping, it is for subsequent use to obtain diazonium salt in 6 hours in 10-15 ℃ of insulation; Meanwhile, structure is dissolved in the solution of 10mL sulfuric acid, 300mL water, 300 gram ice compositions suc as formula compound 27.6 grams shown in (II), then adds the diazonium salt of above-mentioned preparation, after reaction finishes, filtration, washing, drying obtain suc as formula the azoic dyestuff shown in (I-h).This dyestuff can provide the every fastness ability of polyester piece good good blueness.
Embodiment 2-12
Adopt the method for embodiment 1 to synthesize suc as formula the azo type heterocyclic dispersed dye shown in (I), wherein various substituting groups are defined in the table 1, can use it for polyster fibre dyeing, and this dyestuff can provide the every fastness ability of fabric good blueness.
