C.I. Disperse Red 60 - Uses and synthesis methods

use

1. transparent red FB is used for coloring various plastics, oils, waxes and inks.

2. Mainly used for dyeing polyester and its blended fabrics, can also be used for dyeing vinegar fiber and nylon, pure dyes can be used for plastic coloring, and can also be used for transfer printing

3. disperse red 3B is the main dye for dyeing polyester, with bright color and light, excellent sun fastness, good levelness and slightly poor sublimation fastness. It is often composed of three primary colors with disperse yellow RGFL and disperse blue 2BLN, which is suitable for high temperature and high pressure dyeing. It can be used for direct printing of polyester and nylon fabrics, and also for transfer printing. The performance of dyed diacetate fiber and triacetate fiber is similar to that of dyed polyester. The color light of dyed nylon and acrylic fiber is blue, the dyeing speed is slow, and the levelness and depth of dyeing are medium.

production method

1. 1-aminoanthraquinone is used as raw material, brominated (or chlorinated), hydrolyzed, and then condensed with phenol to obtain the product. The finished product is filtered, ground and dried..

add 80L of water and 33.45kg of 1-amino anthraquinone to the enamel pot, stir for 15min, put it into a 1000L pot, and adjust the reaction liquid volume to about 500L. 18.3kg of 30% hydrochloric acid was added, 32kg of bromine was added under cooling, and stirred at room temperature for 1h. Continue to stir for 2.5-3h, add hypochlorous acid pot solution 11.5kg (containing about 100% of available chlorine), react at 80 ℃ for 12h, add about 3-4kg of sodium nitrite solution, and completely disappear the excess bromine. Cool to 40-45 ℃, filter, wash with water to neutral, and dry the filter cake at 85-95 ℃.

add 1200kg of 3%-5% fuming sulfuric acid to the hydrolysis pot, raise the temperature to 50 ℃, add 120kg of the above bromide, stir for 1h to dissolve all of it, react at 120 ℃ for 10-12h, reach the end point, cool to 50 ℃, dilute, filter, neutralize the filter cake with alkali, then filter, and dry at 85-95 ℃.

46kg of potassium carbonate and 292kg of phenol were added into the reaction pot, heated to 120 ℃, 165kg of the above hydrolysate was added within 1h, and then reacted at 140-145 ℃ for 6-8h. After the phenol is recovered, it is filtered, washed with water until neutral, and dried to obtain the finished product.

According to another study, the bromination reaction can be carried out in sulfuric acid medium. 20 parts of 1-aminoanthraquinone and 1.2 parts of acetic acid were added to 100 parts of 94% sulfuric acid, heated to 110 ℃ under stirring, 28.7 parts of bromine were added dropwise at this temperature (completed within 5 hours), and the heat preservation reaction was continued for 5 hours. The yield of 2, 4-dibromo-1-aminoanthraquinone can reach 98.7%. Adding benzyl triethylammonium chloride as phase transfer catalyst in the condensation step can improve the yield, reduce the amount of phenol, and save the phenol recovery operation. The process is as follows: add 24.2g hydrolysate, 12.3g potassium hydroxide solution (48%), 9.9g phenol, 8g the above catalyst and 86.5mL water to the reactor, raise the temperature to (95±5)℃, stir for 10-12h, and reach the end point. Filtered, washed and dried products.

2. Using 1-amino anthraquinone and phenol as raw materials, 1-amino anthraquinone is first halogenated and hydrolyzed to obtain 1-amino -4-hydroxy -2-halogenated anthraquinone, and finally condensed with phenol to obtain the product. The finished product is filtered and dried..
