活性艳兰X-BR - Uses and synthesis methods
use
reactive brilliant blue X-ARL is also called reactive brilliant blue X-BR. it is one of the few varieties of reactive x-type dyes used for direct printing of cotton cloth. it is used for dyeing, printing and direct printing of cotton, silk, viscose and other fabrics. The structure is the same as that of active blue 1.
rose red is often dyed with reactive red and purple S-2R (5%) (brilliant blue X-BR dosage is about 15%). It is dyed green with reactive light yellow X-6G at a dosage of 10:1, and the color matching is not the main color. When knitted cotton fabrics are bleached, reactive brilliant blue X-BR can be used as bluing agent to increase whiteness, and the dosage is about 05g/L. Reactive brilliant blue X-BR dye is not resistant to smoke and is easy to produce wind marks, which can be improved by ethylenediamine 2g/L treatment.
biological activity
Reactive Blue 4 is an anthraquinone dye that can be used as a single colorimetric chemical sensor for the continuous determination of multiple analytes with different optical responses in aqueous media. Reactive Blue 4 has phytotoxicity, cytotoxicity and genotoxicity.
use
reactive brilliant blue X-BR is mainly used for dyeing cotton, viscose fiber twisted yarn and fabric, with small affinity, good levelness, fixation rate of about 60%, and good fastness, especially light-colored sunlight fastness, which is very suitable for dyeing light blue. It is also used for direct printing of cotton and viscose fabric, and is mostly used for viscose fabric. Due to wind printing, it is generally limited to small pieces of surface. It is pink red with active red-purple X-2R and green with active light yellow X-6G, and the dosage is only 1/10. It can also be used for direct printing of nylon, silk, wool, nylon fabric, silk and copper ammonia fiber fabric. When used for dyeing cotton and other fiber blended fabrics, vinylon and wool are stained seriously, nylon is stained, polyester, polypropylene and acetate are not stained. It can be used for two-bath dyeing of polyester-cotton blended fabric and polyester-cotton blended knitted fabric. It can be dyed in dark green with reactive orange X-GN, light green with reactive yellow X-R, or various light colors with both. Used as a bluing agent, it can increase the whiteness of cotton knitted bleached products.
production method
using bromine, 2, 4-diaminobenzenesulfonic acid and cyanuric chloride as raw materials, first condensation of 2, 4-diaminobenzenesulfonic acid and bromine, and then further condensation with cyanuric chloride for the second time, salting out, filtering and drying to obtain the finished product...
add 500L of clear water to the first condensation pot, stir and raise the temperature to 85 ℃. 191kg of bromine (100%) was added to form a uniform suspension (total volume about 1000L) under stirring. Then add 112.8kg 2,4-diaminobenzenesulfonic acid (100%) and 200kg of sodium bicarbonate (100%), raise the temperature to 85 ℃, keep the temperature for 30min, and add 10kg of cuprous chloride (100%) solution (without free sodium sulfite). Control at 83-85 ℃,pH = 9 for 3h. The end point was measured (the sample was unfolded on the filter paper, and the end point was the disappearance of bromine). Keep the temperature at 90 ℃ for 2 hours.
at the end of the reaction, add water to dilute to 4500L, stir for 15min, add 150kg of light calcium carbonate, stir for 30min at 75-80 ℃, filter while hot to remove purple byproduct dye.
put the filtrate into a neutralization pot, adjust it to pH = 2 with hydrochloric acid, add salt with a solution volume of 10%-15%, stir for 1h, take samples to measure the end point (no blue infiltration ring on the filter paper is the end point), filter to obtain a refined filter cake.
add 1000L of water to the dissolved pot, add 30kg of sodium carbonate and refined filter cake under stirring, beat, adjust the volume to 3000L,pH = 7.5, to obtain refined solution.
add 300L of water to the second condensation pot, add 81.1kg (about 0.44kmol) cyanuric chloride, beat the slurry below 0 ℃ for 45min, add the refined solution prepared in the previous step, adjust the volume to 4500L at 15 ℃, stir for 1h, add trisodium phosphate to make pH = 6.5 or so; Continue to stir for 3 hours, the pH value should be kept between 6.3 and 6.5, and the temperature should not exceed 18. Filter to remove cyanuric chloride impurities.
the filtrate is collected in a salting-out pot, urea 26.4kg (about 0.44kmol) is added to the filtrate, the temperature is increased to 43 ℃ within 1 hour, salt with a total volume of 20% of the filtrate is added, stirred at 40-42 ℃ for 2 hours, sampled (the infiltration ring of spots on the filter paper is clear), filtered, and the filter cake is dried at 80-85 ℃ to obtain about 410kg.
