Удосконалення синтезу термопереводного барвнику антрахiнонового Жовтого 6З

The conditions for obtaining substances and intermediates using the available purified raw materials of coke chemistry were experimentally selected and improved. The technological process and the scheme of synthesis of the thermocouple dye of yellow 6Z is developed, using as a raw material isolated from coke resin and purified anthraquinone. Improved technology for the synthesis of thermocouple dye yellow 6Z is a little expensive and allows you to increase the output without degrading the quality of the final form of the dye. Translated printing is of great interest for the proposed printing of dispersion dyes of chemical fibers. Translational coloring of textile materials and products as one of the simplest, most economical and environmentally friendly technological processes. Initially, the method was printing has a number of indisputable advantages that make one of the most promising areas in the coloring of textile fabrics. The method of thermal printing is simple in technical design: in the presence of a printed substrate for the printing process is enough to have a thermal press or calender, which can be serviced by one operator, which saves capital costs for equipment and leads to minimizing the workplace. Translation printing is of great interest for dyeing textile materials and products as one of the simplest, most economical and environmentally friendly technological processes. Initially, the method was proposed for. The image printed on the fabric has a mirror image.The improved technology of synthesis of thermal transfer dye yellow 6C in comparison with the current technology takes place at a much lower temperature of 45±5oC (according to the current technology - 120±5oC) without pressure at the duration of the methoxylation reaction 6 hours (instead of 46 hours according to the current technology). This technological technique allows to increase up to 8% the yield of the target product in high quality.The yield of dye by advanced technology per loaded 2-bromobenzantrone is significantly higher compared to the yield of the current technology.In the process of improving the technology, the selected conditions for obtaining substances and intermediates using available purified raw materials of coke chemistry in the synthesis of thermal transfer dye yellow 6C anthraquinone were substantiated, the technological scheme of synthesis was drawn up final form of dye, the technological scheme of synthesis is made, using as initial raw materials the anthraquinone isolated from coke resin and allowed to increase with improvement an exit of a final form of dye.
