Embodiment 1

[0028] Add 50 milliliters of sulfuric acid in the flask, add 16.5 g of p-aminobenzenesulfonyl fluoride at room temperature, add 13 grams (100%) of nitrosyl sulfuric acid, and react with diazonium for 5 hours. After the reaction is completed, add 20 milliliters of sulfuric acid, 900 grams of In the mixture of ice water and 20.6 grams of compounds shown in formula (2),

[0029] Formula (2)

[0030] After the addition, continue to react for 2 hours, rise to 60° C. and keep warm for 2 hours, cool, and filter with suction to obtain the fluorine-containing dye shown in formula (3):

[0031] Formula (3)

[0032] When the dye is dyed on polyester-spandex blended fabric, a bright orange color is obtained with excellent properties.

Embodiment 2

[0034] Add 50 milliliters of sulfuric acid to the three-necked flask, add 23.4 grams of 3,5-dichloro-4-aminobenzenesulfonyl fluoride at room temperature, and add 13 grams (100%) of nitrosyl sulfuric acid at the same time, and react with diazonium for 5 hours. After completion, add in the mixture consisting of 20 milliliters of sulfuric acid, 900 gram ice water and 35.4 gram compounds shown in formula (4),

[0035] Formula (4)

[0036] After the addition, continue to react for 1 hour, add 1000 milliliters of water, slowly rise to 80 ° C and keep warm for 2 hours, cool, and suction filter to obtain the monoazo compound containing triazine structure shown in formula (5):

[0037] Formula (5)

[0038] The polyester fiber is dyed with the dye to obtain a bright red color with excellent fastness properties.

Embodiment 3

[0040] Add 50 ml of sulfuric acid into a three-necked flask, add 20 g of o-chloro-p-aminobenzenesulfonyl fluoride at room temperature, add 13 g of nitrosyl sulfuric acid (100%) dropwise at 30°C, and react at 30-35°C for 3 hours. After finishing, be added dropwise in the mixture that is formed by 20 milliliters of sulfuric acids, 900 gram ice waters and 32.2 gram compounds shown in formula (6),

[0041] Formula (6)

[0042] After adding, continue to react for 2 hours, add 500 milliliters of water, suction filtration, obtain the monoazo compound shown in formula (7):

[0043] Formula (7)

[0044] The polyester fiber is dyed with the dye to obtain a bright red dyed product with excellent fastness properties.

Abstract

The invention discloses a fluorine-containing dye. The structure is shown in formula (I), wherein each group is defined in a specification. Preparation and application of the fluorine-containing mono-azo-compound take the above technical scheme, so the fluorine-containing azo dye has the same bright colored light, complete colored light and the same fastness but is low-cost compared with azo dyes with a furan structure.

Description

a technical field [0001] The invention relates to an azo compound containing fluorine elements, a preparation method and an application thereof, and belongs to the technical field of chemical material preparation. Two background technology [0002] Red or purple dyes with high washing fastness include R-356, R-356: 1 and R-SBWF, which are dyes with furan structure: [0003] [0004] R-356 (R=C 3 h 7 ); [0005] R-356: 1 (R=C 2 h 5 and C 3 h 7 ); [0006] R-SBWF [0007] Although this type of dye has the advantages of excellent washing fastness and bright shade, it is difficult to prepare, complex in process, high in production cost, and there is no blue dye. [0008] The invention provides a low-cost dye, an azo dye containing fluorine element in the molecular structure, which has the same bright shade, complete shade and the same fastness as the furan structure. Three invention content [0009] The object of the present invention is to provide a kind of pre...
