n the conventional-water based coloration methods, polymer and textile industries requires more amount of water for the
coloration demands and also needs several chemical additives like dispersing agents and surfactants for enhancing the
solubility of dye in water. Therefore eco-friendly purposes, related industry looking for environmentally and bio friendly
process to replace the conventional-water based application method. In order to overcome, the biological, the ecological and
economical disadvantages, super critical fluid dyeing process has been interested and introduced nowadays. In the supercritical
fluid system, supercritical fluids were used as dye solvents instead of water. A supercritical fluid can be defined as a substance
above its critical temperature (Tc) and pressure (Pc). Under these described conditions the substance has unique properties,
in that it exists as a vapor and liquid in equilibrium. Carbon dioxide is particularly attractive due to its green properties
like recyclable, non-toxic, biologically friendly and non-flammable advantages. Anthraquinone disperse dye molecules are
plays a vital role in the coloration industry. These molecules are more stable under the experimental conditions and as well
as in various organic solvents when during the calibrations. Molar absorption coefficients of anthraquinone dyes are allows
spectroscopic determination even at very low concentrations. Series of anthraquinone blue dye derivatives have been designed
and synthesized from available moieties with simple and convenient methods. Herein, anthraquinone dyes were synthesized,
analyzed and fully characterized by
1
HNMR,
13
CNMR, UV-Vis and HRMS. The UV-Vis spectra of the dyes were indicated that
the absorption wavelengths of the dyes were about bathochromic wavelength range, which shows that they were blue dyes.
These new developed dyes can be considered as eco-friendly and biological friendly application system.
