2% 2C5 - isopic acid, its properties are various. This substance, at room temperature, is usually solid, like powder chips, with a nearly plain white color and a fine texture. Its melting degree is quite high, and if you want to make it melt, you need to force it at high temperature, about hundreds of degrees square melting. This cover has a strong attractive force between molecules and a tight structure, so it needs more energy to break its polymerization state.
Furthermore, 2% 2C5 - isopic acid has poor solubility in water. Water is a polar liquid, and this acid has a special molecular structure and weak polarity. According to the principle of similar compatibility, it is difficult to dissolve in water. However, in organic solvents, such as acetone and ethanol, it has a certain solubility. Due to the fact that the molecular polarity of the organic solvent is similar to that of the acid, it can interact with the acid molecules to disperse them.
When it comes to stability, 2% 2C5-isopic acid is quite stable under normal conditions, and the molecular structure is firm and not easy to decompose by itself. When it encounters strong acids and bases, it can react. Strong acids and bases can break their original chemical bonds, causing them to change their structure and form new products. In addition, in case of high temperature and aerobic environment, oxidation reactions may occur, causing their structure and properties to change.
Its volatility is very small, because of the large intermolecular force, it is difficult for molecules to break free and escape into the gas phase. This characteristic allows it to maintain its own state for a long time when it is stored in a solid state, and it is less lost due to volatilization. In short, the physical properties of 2% 2C5-isodicarboxylic acid are closely related to its molecular structure. The structure determines its properties, and its properties determine its use. It is unique in many fields such as chemical industry and scientific research.

The chemical properties of 2% 2C5-diacetic acid can be investigated. This compound has the property of carboxyl group, and the carboxyl group can be acidic. It can be neutralized with bases. In case of sodium hydroxide, that is, raw salt and water, the formula is roughly: 2% 2C5-diacetic acid + sodium hydroxide → 2% 2C5-diacetic acid + water.
And because it has a dicarboxyl group, it can also be used for esterification. If it is an alcohol, it can form an ester in the context of acid catalysis. Taking ethanol as an example, 2% 2C5-ethyl diacetate should be produced, which should be heated, and sulfuric acid is often used as a catalytic agent. The formula is roughly: 2% 2C5-diacetate + 2 ethanol + 2% 2C5-diacetate + 2 water. This should be a reversible response. The yield of the ester to be increased, or the amount of alcohol to be added, or the amount of water to be removed.
Furthermore, the molecular structure of 2% 2C5-diacetate should also be active in nucleophilic substitution due to the specific carbon chain and functional group arrangement. The carbon in its carboxyl ortho-position may be attacked by nucleophilic reagents and cause substitution changes. If there are nucleophiles such as halogen ions, under the appropriate strips, or can replace a group of carboxyl ortho-sites, then a specific solvent and temperature strips are required.
and 2% 2C5-isotropic diacetic acid may also be involved in the polymerization. Because of the dicarboxyl group, it can be polymerized with compounds with polyhydroxy groups or polyamines to form high polymers. If it is polymerized with dibasic alcohols, it can form polyesters, which may be useful in the field of materials and can produce specific polyester materials, which are important for industrial, medical and other industries. The application of its polymerization often requires catalytic agents and appropriate temperature and pressure to promote it.

The synthesis methods of 2% 2C5 -adipic acid have different paths, and the following are the common ones.
First, cyclohexanol is used as the beginning and obtained by oxidation. Among them, the strong oxidizing agent prepared by potassium dichromate and sulfuric acid can be used to oxidize cyclohexanol to form cyclohexanone first, and then continue to oxidize to adipic acid. The formula for the chemical reaction is roughly as follows:
\ (C_ {6} H_ {11} OH + [O]\ stackrel {K_ {2} Cr_ {2} O_ {7}, H_ {2} SO_ {4}} {\ longrightarrow} C_ {6} H_ {10} O + H_ {2} O\) (cyclohexanol to cyclohexanone)
\ (C_ {6} H_ {10} O + [O]\ stackrel {K_ {2} Cr_ {2} O_ {7}, H_ {2} SO_ {4}} {\ longrightarrow} HOOC (CH_ {2}) _ {4} COOH\) (cyclohexanone to adipic acid )
However, in this way, oxidizing agents such as potassium dichromate are quite toxic, and there are many wastes generated after the reaction, which are not very friendly to the environment.
Second, cyclohexene is used as a raw material, and ozone oxidation is used. Shilling cyclohexene reacts with ozone to generate odorous oxides, and then reductive hydrolysis can obtain adipic acid. The steps are roughly as follows:
\ (C_ {6} H_ {10} + O_ {3}\ longrightarrow C_ {6} H_ {10} O_ {3}\) (to generate odorous oxides)
\ (C_ {6} H_ {10} O_ {3} + Zn + H_ {2} O\ longrightarrow HOOC (CH_ {2}) _ {4} COOH + Zn (OH) _ {2}\) (reductive hydrolysis to obtain adipic acid)
Although this method is relatively clean, ozone production is not easy, and equipment requirements are high.
Third, butadiene is used as the starting material and synthesized by multi-step reaction. Butadiene first undergoes a diene addition reaction with ethylene to obtain cyclohexene derivatives, which are then converted into adipic acid through oxidation and other steps. There are many reaction steps in this path, and the reaction conditions of each step need to be carefully regulated. However, the raw material butadiene comes from a relatively wide range of sources.
There is also a method of biosynthesis, which uses the action of microorganisms or enzymes to catalyze the conversion of specific substrates to adipic acid under mild conditions. This method is green and environmentally friendly, and the energy consumption is low. However, the current technology is not yet mature. There are still many problems to be solved in large-scale production, such as strain selection, enzyme stability and activity improvement.

2% 2C5 - isosuccinic acid, the price of the market, it is difficult to have a fixed number. The price of the cover often changes due to various reasons, such as the amount of production and supply, the situation of demand, the progress of manufacturing, and the state of competition in the market.
Looking at the surface of various production and supply, if there are many producers and the output is abundant, the market will be full of goods, and the price may stabilize or even decline. On the contrary, if there are few producers, or due to weather, lack of raw materials, etc., the output will decrease, and the price will be thin and high.
The situation of demand and demand is also the main reason. If it is widely used in medicine, chemical industry, etc., and there are many seekers, the price will rise. If the demand decreases sharply at a certain time, the price will also drop.
The progress of manufacturing can increase the production efficiency, reduce the cost, and the price may also drop. And the market competition is intense, and the producers compete for the market, or cut the price to attract customers, so that the price fluctuates.
In summary, in the market today, the price of 2% 2C5-isosuccinic acid is roughly between hundreds and thousands of yuan per kilogram. However, this is only an approximate number. The actual price shall be subject to the current market conditions. If the buyer wants to know the exact price, he needs to check the market conditions in detail and consult the producers and sellers before he can obtain it.
