Embodiment 1
[0030] (1) the chlorobenzene of 50g, the water of 100g, the 1-nitroanthraquinone of 25g, the 2,6-dibromo-p-methylaniline of 27g and the tablet caustic soda of 7.5g drop into reactor, and the airtight reactor is opened and stirred, And raise the temperature to 120°C-130°C for heat preservation. After 9 hours, the heat preservation is over, add 50g of water, and recover chlorobenzene under reduced pressure. After the recovery is completed, filter, wash and dry to obtain 44.2g of primary condensation material.
[0031] (2) Put 132.6g of DMAC and 44.2g of primary condensation material into the reactor, raise the temperature to 90°C, start to add 10g of acetyl chloride dropwise, control the dropping time at 0.5h, and keep the temperature for 14h after the dropping, After the heat preservation is over, cool down and stand by.
[0032] (3) 19.89g of NaHCO 3 Put it into the system of step (2), close the reactor, heat up to 100°C and start to keep warm, keep warm for 12h, drop to 60°C...
Embodiment 2
[0036] (1) The chlorobenzene of 75g, the water of 150g, the 1-nitroanthraquinone of 25g, the 2,6-dibromo-p-methylaniline of 27g and the tablet caustic soda of 8.75g drop into reactor, and the airtight reactor is opened and stirred, And raise the temperature to 120°C-130°C for heat preservation. After 9 hours, the heat preservation is over, add 75g of water, and recover chlorobenzene under reduced pressure. After the recovery is completed, filter, wash, and dry to obtain 45g of primary condensation material.
[0037] (2) Put 135g of DMAC and 45g of primary condensation material into the reactor, raise the temperature to 90°C, start to add 11.5g of acetyl chloride dropwise, and control the dropping time at 0.5h. Finished, cool down and set aside.
[0038] (3) 20.25g of NaHCO 3 Put it into the system of step (2), close the reactor, heat up to 100°C and start to keep warm, keep warm for 12h, drop to 60°C, start adding 405g of water dropwise, cool down to room temperature naturall...
Embodiment 3～8
[0042] Take 2g of disperse red P-WFS prepared in Example 1 or 2, and 1000ml of water, mix and stir to form a suspension; take 50ml of the suspension, 50ml of water, and 0.6g of hydrogen peroxide, mix them evenly, and start to adjust the pH value, ranging from 4 to 13, respectively. Adjust with acetic acid and liquid alkali with a concentration of 5w%, add 5g of polyester fiber cloth when the heating temperature is 60-70 ℃, then rise to 130 ℃ within 30min and keep at this temperature for 1h to dye, cool down after finishing, wash with water , drying cloth samples, and test their color fastness to washing, rubbing and sublimation.
