Looking at its appearance, it is mostly powdery, and the color is often between white and beige. The shape of this color is like the purity of the first snow in winter, and the simplicity of the yellowish autumn rice. Its texture is delicate, and the touch is like a smooth powder.
When it comes to solubility, it has a certain ability to dissolve in water, just like fish merging into a stream. Although it is not completely integrated, it also has a somewhat affinity. In polar organic solvents, there are also soluble properties, such as ethanol, acetone, etc., in which it is like ice crystals entering warm wine, gradually melting, showing good dissolution characteristics.
The nature of the melting point is quite critical. After fine determination, its melting point is within a specific range. This value is its inherent physical signature, like a human fingerprint, unique. At this temperature, the state of matter quietly changes from solid to liquid, like ice and snow meeting the warm sun, gradually turning into babbling water.
Stability is also one of its important physical properties. Under normal conditions, its structure is as stable as Mount Tai, which can maintain its own shape and properties for a long time, and is not easily disturbed by external minor factors. However, if placed in a harsh environment such as high temperature, strong acid and alkali, its stability will be like thin ice in the face of fire, the structure may change, and the properties will also change.
Its density is also fixed, and this value can be compared with other substances to show the difference between its severity. Density, like a ruler for measuring the "weight sense" of a substance, is an important part of its physical properties and plays a role that cannot be ignored in many practical applications.

2- What is the production method of Phenylamino-5-Naphthol-7-Sulfonic Acid?

2-Phenylamino-5-naphthol-7-sulfonic acid, the method of its preparation, although the ancient book "Tiangong Kaiwu" does not specify the method of this specific substance, it can be deduced according to the general principles of chemistry and ancient techniques.
The first raw materials need to be selected from naphthalene, aniline and sulfonated reagents. The ancient method of preparation often relies on natural materials and simple processes. Or take naphthalene first and sulfonate it under appropriate conditions. This step requires temperature control and time to achieve a specific sulfonated check point. " Although Tiangong Kaiwu did not say this, sulfuric acid, etc. were used for sulfonation in ancient times. Heating in the kettle was enough to observe the change.
Then, add phenylamino group. It can make aniline react with the sulfonated naphthalene derivatives, or find a mild catalytic means, an ancient catalytic idea, or use acid and base to promote its formation. It is necessary to choose an appropriate solvent to help it dissolve and facilitate the reaction. During the reaction, closely observe its color change, temperature change, etc., to determine the process.
And it needs to be separated and purified. Ancient separation, or the method of precipitation and crystallization. The product is precipitated in a suitable solvent to remove its impurities, and then refined by recrystallization to observe its crystal shape and color to achieve high purity. Although this specific substance is not mentioned in "Tiangong Kaiwu", the ancient chemical techniques are re-observed and practiced. According to this method, 2-phenylamino-5-naphthol-7-sulfonic acid may be obtained.

2- What is the price range of Phenylamino-5-Naphthol-7-Sulfonic Acid in the market?

I have not heard the exact price range of 2 - + phenylamino - 5 - naphthol - 7 - sulfonic acid in the market. The price of these chemical materials often changes for a variety of reasons.
One is the difference in output from the place of origin. If the place of origin is rich in resources, has a large production scale, and can be supplied in large quantities to the market, the price may become more affordable. On the contrary, if the place of origin is short of resources, the output is scarce, and the supply and demand are unbalanced, the price will rise.
Second, the change in the cost of raw materials. If the price of raw materials required to make this acid rises and falls due to market fluctuations and scarcity of resources, the price of this acid will also be easier. If the price of raw materials rises, the manufacturer will raise the price in order to ensure profitability.
Third, the market demand situation. If many industries have strong demand for this acid, such as dyes, medicine and other industries rely on it as a key raw material, and the demand increases greatly, the price will be high. On the contrary, if the demand is low, the price may drop.
Fourth, the shadow of quality differences. Those with high quality meet the industrial demand of high standards, and their price is higher than that of ordinary quality.
And times change, the market is changing rapidly, and the price of this acid is difficult to have a constant number. Therefore, in order to know the exact price range, it is necessary to carefully observe the recent market conditions of the chemical market, consult industry experts, merchants, or refer to the data of professional chemical information platforms, in order to obtain a more accurate judgment.
