C.I. Pigment Red 123, that is, 9-bis (4-ethoxyphenyl) isoquinone [4 ', 5', 6 ': 6,5,10] anthracene [2,1,9-def] isoquinoline-1,3,8,10 (2H, 9H) -tetraketone, the physical properties of this substance are as follows:

Its appearance is often a bright red powder, which is a common form of pigment substances and is easy to disperse and apply in various media. In terms of solubility, the pigment has very low solubility in polar solvents such as water and is almost insoluble. However, it has certain dispersibility in some organic solvents such as aromatics and ester solvents, but it is difficult to achieve complete solubility.

In terms of heat resistance, C.I. Pigment Red 123 exhibits excellent performance. It can withstand higher temperatures, usually in the range of 200 ° C - 250 ° C, and its color and crystal structure can remain relatively stable without significant discoloration or decomposition. This property makes it suitable for high-temperature processing fields, such as high-temperature injection molding of plastics, hot-melt spinning of fibers, etc.

Regarding light resistance, the pigment has excellent light resistance. After long-term light exposure, its fading degree is extremely slight. When used in outdoor environments or under strong light conditions, it can maintain the original color and brightness for a long time, so it is widely used in outdoor coatings, plastic products and other products with strict light resistance requirements. The density of

is about 1.3-1.5g/cm ³. This density value allows it to be relatively evenly distributed when mixed with other materials, without serious sedimentation or delamination due to excessive density differences. At the same time, the pigment has good hiding power, and a small amount of pigment can effectively cover the underlying material, presenting a full and uniform color effect.

To prepare C.I. Pigment Red 123, that is, 9-bis (4-ethoxyphenyl) isoquinone [4 ', 5', 6 ': 6,5,10] anthracene [2,1,9-def] isoquinoline-1,3,8,10 (2H, 9H) -tetraketone, the method is as follows:
First take an appropriate amount of 4-ethoxybenzaldehyde, place it in a clean reactor, add an appropriate amount of organic solvent, such as dichloromethane, stir to fully dissolve it to form a homogeneous solution. Take another appropriate amount of isoquinol [4 ', 5', 6 ': 6,5,10] anthracene [2,1,9-def] isoquinoline-1,3,8,10 (2H, 9H) -tetraketone parent compound, also dissolved in an organic solvent, slowly pour into the above solution containing 4-ethoxybenzaldehyde, and at the same time, add an appropriate amount of basic catalyst, such as potassium carbonate, to promote the reaction.
Maintain the reaction system at a specific temperature, between about 60 and 80 degrees Celsius, and stir continuously to make the reactants fully contact and react. During this process, pay close attention to the reaction process, and monitor the degree of reaction by thin layer chromatography (TLC). After the reaction is completed, the reaction mixture is cooled to room temperature, and then separated and purified. < Br > The organic phase was collected by extraction with a suitable organic solvent for several times, and then dried with anhydrous sodium sulfate to remove the moisture. After that, the organic solvent was removed by reduced pressure distillation to obtain a crude product. Further purification was carried out by column chromatography, suitable silica gel was selected as the stationary phase, and a specific proportion of petroleum ether and ethyl acetate mixture was used as the mobile phase. The target product fraction was collected and dried to obtain pure C.I. Pigment Red 123.

I look at the price range of the pigment you are asking about "C.I. Pigment Red 123,9 - bis (4 - ethoxyphenyl) isoquino [4 ', 5', 6 ': 6,5,10] anthra [2,1,9 - def] isoquinoline - 1,3,8,10 (2H, 9H) -tetrone" in the market. However, this pigment is not a widely known and common product, and its price is easily influenced by many factors.

First, the manufacturers of production are different, and their craftsmanship, quality and price are also different. Large manufacturers focus on quality and abide by standards, and the cost may be high, but the price may be high; small manufacturers have stricter cost control, and the price may have an advantage.

Second, the amount of purchase has a great impact. If it is a small purchase, for laboratory research and the like, the seller may have a higher unit price due to cost considerations such as logistics and packaging; if it is a large purchase, such as for industrial production, the seller may give a discount due to the idea of small profits but quick turnover, and the unit price will be reduced.

Third, the state of market supply and demand is also critical. If the market demand is strong and the supply is limited, the price may rise; if the supply exceeds the demand, the seller may reduce the price and promote it.

As far as I know, the price of this pigment may range from tens to hundreds of yuan per kilogram. However, it is difficult to determine its specific price range, because the price of pigments fluctuates frequently in the market, and there are differences in various markets. To know the exact price, you need to consult pigment suppliers, distributors, or check in detail on the chemical product trading platform to obtain the exact price range at the moment.
