Synthesis process of 1,4-diamino-2-anthraquinone sulfonate

The invention discloses a synthesis process of 1,4-diamino-2-anthraquinone sulfonate, belonging to the field of organic synthesis. The process comprises the steps of adding a 1,4-diamino-anthraquinoneoxysome and o-dichlorobenzene into a container, dropwise adding chlorosulfonic acid while holding the temperature at 30-50 DEG C, heating to 140+/-3 DEG C, holding the temperature for 6+/-1 hours, cooling to 60-80 DEG C, transferring to water containing sodium carbonate, stirring for a period of time, adjusting the pH to 7.5+/-0.1, steam distilling the solvent, cooling to 80+/-5 DEG C, adjustingthe pH to 1+/-0.2 with sulfuric acid so as to separate out 1,4-diamino-2-anthraquinone sulfonate, and filtering, so as to obtain the 1,4-diamino-2-anthraquinone sulfonate product. The use amount of chlorosulfonic acid in the process is one third of that of an original process, and the amount of byproduct hydrochloric acid is one third of that of the original process, and no sulfur dioxide gas is produced.

Visible-light photocatalytic activity of chitosan/polyaniline/CdS nanocomposite: Kinetic studies and artificial neural network modeling

Chitosan/polyaniline (CS/PAni), chitosan/CdS (CS/CdS) and chitosan/polyaniline/CdS nanocomposite were synthesized and characterized using X-ray diffraction pattern analysis, FT-IR spectroscopy and scanning electronic microscopy. The adsorption performance and photocatalytic activity of CS/PAni/CdS was compared with CS/PAni and CS/CdS in the removal of Reactive Blue 19 (RB19) dye. After five cycles of experiments under visible light irradiation, CS/PAni/CdS retained high photocatalytic activity which confirmed good stability of nanocomposite. Moreover, the kinetics of decolorization was investigated and novel equation rate for dye removal was established by considering two parallel mechanisms including adsorption and surface photocatalytic degradation of dye by CS/PAni/CdS. Artificial neural network was employed to develop a model for predicting the decolorization efficiency and determining the relative importance of operational parameters. A 3-layer perceptron network with optimized 5:10:1 topology could provide adequate predictive performance (R2 = 0.983). Moreover, the photocatalytic degradation of RB19 was monitored by measuring the total organic carbon (TOC) and GC-MS analysis, enabling the evaluating the mineralization and identifying the intermediates. During 120 min of experiment, more than 80% of TOC was removed.

On the mechanism of biotransformation of the anthraquinonic dye acid blue 62 by laceases

We used the recombinant CotA-laccase from the bacterium Bacillus subtilis to investigate the biotransformation of the commercial anthraquinonic dye Acid Blue 62. Kinetics of dye biotransformation at pH6 follow a Michaelis-Menten model. NMR and several MS techniques allowed the identification of intermediates and final products of the enzymatic biotransformation. The main final product obtained, l-[(4-amino-9,10-dioxo-3-sulfo-9,10-dihydroanthracen-l-yl)diazenyl]-4- cyclohexylamino-9,10-dioxo-9,10-dihydroanthracene-2-sulfonic acid, is formed through the creation of an azo link and has been previously identified as an intermediate compound in the biodegradation of Acid Blue 62 by crude fungal preparations. The identification of 1,4diamino-9,10-dioxo-3-sulfo-9,10- dihydroanthracene 2-sulfonic acid and of cyclohexanone, in reaction mixtures with CotA-laccase and also its presence in reactions performed with the LAC3 lacease from the fungus Trametes sp. C30, suggest the occurrence of coupling reactions between the intermediate products of dye oxidation. Based on these results, we propose a mechanistic pathway for the biotransformation of Acid Blue 62 by laceases. A bioassay based on the inhibitory effects of the dye and its enzymatic products on the growth of Saccharomyces cerevisiae shows the importance of laceases in reducing dye toxicity.
