Description
Technical field
The invention belongs to technical field of dye, and in particular to a kind of supercritical CO2With anthraquinone type reactive disperse dyes forerunner
The synthetic method of body.
Background technology
The appearance and development of reactive disperse dyes can trace back to the sixties in last century five, but because it is by use condition
Having a great influence, be difficult to accomplish to contaminate on uniformly when being dyed to polyester/cotton blended fabric, application is poor, thus in evolution
Encounter bottleneck (bibliography：The significant progress of reactive dye and fundamental research achievement [J] dyestuffs and dye in 50 years
Color, 2008,2：1-9,44.).And utilize supercritical CO2Fluid staining technique can realize that reactive disperse dyes is knitted to polyester cotton blending
The dyeing of thing and natural fiber, new vitality (bibliography is filled with for its development：One-bath dyeing of
polyester/cotton blends with reactive disperse dyes in supercritical carbon
Dioxide [J] .Textile Research Journal, 2004,74 (11)：989-994；Technical Progress in Modem Reactive Dyestuffs
[J] prints and dyes, and 2004,2：37-42；Dyeing [J] of reactive disperse dyes to natural fiber is external in supercritical carbon dioxide
Textile technology：Weaving knitted dress chemical fibre dyeing and finishing, 2003,9：22-27.).
In terms of reactive disperse dyes synthesis, the report on anthraquinone ring is less, and method is also more single, usually exists
Active group is introduced on the basis of existing disperse dyes, it is of less types.
Reacted using Ullmann and carry out the synthesis of dyestuff or dyestuff intermediate before this it has been reported that but the dyestuff master that is related to
If reducing dye, it can be common that amino anthraquinones carries out condensation reaction with chloroanthraquinone under catalyst action, so as in anthraquinone core
Upper introducing imino group generation anthraquinone group with imine moiety, or by generating carbon-carbon bond, prepare some condensed ring reducing dyes；
Ullmann reaction also have important application in acid dyes, usually using bromamine acid as raw material, in alkaline aqueous solution with substitution
Arylamine reacts (bibliography：Application [J] the dye industries of ullmann reaction in Dyestuff synthesis, 1984,3:1-7.),
And it does not have been reported that in terms of water-insoluble active disperse dyes.
Thus, how to make the synthetic method diversification of reactive disperse dyes, solution reactive disperse dyes species is few, application
The problems such as not strong, turn into the key of breakthrough bottleneck, and can be supercritical CO2The non-aqueous dyeing of natural fiber provides wider in fluid
Wealthy development prospect.
