What are the physical properties of Para-Anisidine-2-Sulphonic Acid?

Para-Anisidine-2-Sulphonic Acid (p-Aminoanisole-2-Sulfonic Acid) is a chemical substance with unique physical properties. Its color is often white to beige powder, and it is fine and uniform in appearance.
In terms of its solubility, it is soluble in water. This property makes it easily dispersible and participates in reactions in chemical reactions or industrial processes of many aqueous systems. Its melting point is also an important physical property, about a specific temperature range. This temperature is the key node for a substance to change from solid to liquid, reflecting the strength of intermolecular forces.
Its density is also fixed. Under common conditions, this value represents the mass of the substance contained in a unit volume. When mixed with other substances or stored in a specific container, it is related to the space occupation and mass distribution.
In addition, stability is also one end of its physical properties. In the environment of normal temperature and pressure without special chemical interference, Para-Anisidine-2-Sulphonic Acid can maintain its own chemical structure and properties unchanged. In case of extreme conditions such as high temperature, strong acid and alkali, or biochemical changes, the physical properties will also change.
In summary, the physical properties of Para-Anisidine-2-Sulphonic Acid are key factors in chemical research, industrial production and other fields, which affect its application mode and application scenarios.

Para-Anisidine-2-Sulphonic Acid is chemically stable?

Para-Anisidine-2-Sulphonic Acid (p-methoxyaniline-2-sulfonic acid), its chemical properties are relatively stable. In this compound, the sulfonic acid group (-SO-H) and the methoxy group (-OCH-H) are connected to the benzene ring. The sulfonic acid group is strongly acidic and can dissociate hydrogen ions in water, showing acidic characteristics, and this group makes the compound have a certain water solubility. Methoxy group is the power supply group, which increases the electron cloud density of the benzene ring through the conjugation effect, which affects the chemical processes such as electrophilic substitution reactions on the benzene ring, which can make the reaction more likely to occur in the adjacent and para-position.
From the perspective of the overall structure, due to the existence of the conjugated system of the benzene ring, the molecular structure is relatively stable. When encountering strong oxidants, the groups of the side chains of the benzene ring may be oxidized, and the sulfonic acid groups are relatively stable. However, under certain extreme conditions, such as high temperature, strong acid and strong base coexisting with strong oxidants, or reactions such as removal of sulfonic acid groups occur.
However, in general chemical environments, as long as extreme conditions such as high temperature, strong oxidation, and strong acids and bases are avoided, Para-Anisidine-2-Sulphonic Acid can usually maintain the stability of its chemical structure and properties, and can be used as a stable intermediate or reactant in many organic synthesis reactions.

What is the production method of Para-Anisidine-2-Sulphonic Acid?

There are many ways to prepare Para-Anisidine-2-Sulphonic Acid in the past. One method is to use p-aminoanisole as the starting material and obtain it through sulfonation reaction. In this process, it is crucial to select a suitable sulfonating agent. Common sulfonating agents, such as concentrated sulfuric acid, fuming sulfuric acid, etc., can be applied.
If concentrated sulfuric acid is used as a sulfonating agent, the temperature should be carefully controlled. At first, the p-aminoanisole is slowly added to concentrated sulfuric acid, stirred at low temperature, and the material is fully mixed. Then, it is gradually warmed to a specific temperature range, usually between tens of degrees Celsius and hundreds of degrees Celsius, to maintain this temperature for reaction. This temperature control is extremely critical. If the temperature is too low, the reaction rate is slow and time-consuming; if the temperature is too high, side reactions will easily occur, which will affect the purity and yield of the product.
If fuming sulfuric acid is used, its sulfonation ability is stronger than that of concentrated sulfuric acid. However, when fuming sulfuric acid is used, the reaction is more intense, so the control of the reaction conditions is more stringent. It is necessary to precisely control the concentration and dosage of fuming sulfuric acid, as well as the reaction temperature and time. Usually, the reaction is mixed at low temperature first, and then slowly heated to make the reaction proceed smoothly to obtain a better product.
In addition, other compounds are also used as starting materials to prepare p-aminoanisole-2-sulfonic acid through multi-step reaction. For example, methoxy and amino groups are introduced into a compound containing benzene ring through a specific substitution reaction, and then the sulfonation step is carried out. Although this multi-step reaction method is complicated, if the reaction conditions of each step are suitable, high-purity products can also be prepared. During the preparation process, after each step of the reaction, separation and purification operations are often required to remove impurities and improve the quality of the product. All of these are methods for preparing p-aminoanisole-2-sulfonic acid.

What is the price range of Para-Anisidine-2-Sulphonic Acid in the market?

The price of p-aminoanisole-2-sulfonic acid in the market often varies with time, place and quality, so it is difficult to be certain. In the past, the description of "Tiangong Kaiwu" was mostly related to traditional craftsmanship and products, and the price of this product was not involved. However, looking at the changes in the market of various chemical materials, the price of such fine chemical products often depends on the cost of raw materials, the situation of supply and demand, and the difficulty of process. If the raw materials are easily available and abundant, and there are many products, and there are few people who want them, the price may be lower; on the contrary, if the raw materials are rare, difficult to make, and there are many people who need them, the price will rise.
I heard that in the past, the trading of chemical materials was especially prosperous in Suzhou, Hangzhou, Shanghai and Shanghai. At that time, merchants negotiated the price, or observed the amount of goods on the market, or observed the simplicity of the workshop system. P-Aminoanisole-2-sulfonic acid, if it is urgently needed for printing and dyeing, medicine and other industries, but the production is not enough, the price will be high, and it is unknown whether it is per catty or as many as two silver; if there is too much output for a while, and there are few people using it, the price may drop to a few dollars per catty of silver.
Today is different from the past. Global commerce and trade are connected, and the chemical industry is booming. Raw materials are produced in exotic regions, and the market is spread across five continents. The price of p-Aminoanisole-2-sulfonic acid may vary according to the price of bulk raw materials such as international crude oil, or due to environmental regulations in various countries. Overall, its price is between tens of yuan and hundreds of yuan per kilogram, but this is only a rough estimate. The actual price still needs to be carefully considered in the current market situation.
