Through chemical modification and transformation, dyes with bright color and excellent fastness can be prepared, which are widely used in textile printing and dyeing industries, giving fabrics rich color and lasting color.
In summary, 4-chlorobenzene-1,2-dicarboxylic acid plays an indispensable role in many industrial fields and has made significant contributions to promoting technological progress and product upgrading in various industries.
It is acidic and can be neutralized with bases to form corresponding salts. This property is derived from the carboxyl group contained in its molecular structure. The carboxyl group is quite active and easy to release hydrogen ions, so it is acidic. And the chemical properties are stable. Under normal conditions, it is not easy to change violently with common substances. However, under certain conditions, such as high temperature and catalyst, it can also exhibit an active state and participate in a variety of organic reactions, such as esterification, meeting with alcohols, and under suitable conditions, ester products can be synthesized, which adds to organic synthesis.
In the general chemical environment, if there is no strong oxidizing agent, strong reducing agent or specific catalyst, 4-chlorobenzene-1,2-dicarboxylic acid can remain relatively stable. However, under extreme conditions such as high temperature, strong acid and alkali, its structure may change. For example, under high temperature, carboxyl groups may be decarboxylated; in strong alkali environments, chlorine atoms may be replaced by nucleophilic groups such as hydroxyl groups.
But in general, under common laboratory and mild industrial conditions, its chemical properties can be said to be stable, and it can maintain its own structure and properties for a certain period of time, providing convenience for related chemical research and industrial applications.
First, it can be obtained by oxidation of 4-chloro-o-xylene. Take an appropriate amount of 4-chloro-o-xylene, place it in a reactor, use acetic acid as a solvent, put in an appropriate amount of metal salts such as cobalt and manganese as catalysts, pass in an appropriate amount of oxygen, and at a certain temperature and pressure, make it oxidize. In this process, the methyl group of 4-chloro-o-xylene is gradually oxidized to a carboxyl group, and finally 4-chloro-benzene-1,2-dicarboxylic acid is obtained. During the reaction, it is necessary to strictly observe the change of temperature and pressure. If the temperature is too high, it may cause the reaction to go out of control and the product will decompose; improper pressure will also affect the reaction rate and yield.
Second, 4-chlorophthalic anhydride is used as raw material. Dissolve 4-chlorophthalic anhydride in an appropriate amount of alkaline solution, such as sodium hydroxide solution, and hydrolyze it to form 4-chlorophthalate, and then use an appropriate amount of strong acid, such as hydrochloric acid, for acidification treatment to precipitate 4-chlorophenyl-1,2-dicarboxylic acid from the solution. In this process, the hydrolysis step needs to control the amount of alkali and the reaction time to prevent excessive hydrolysis; when acidizing, the amount of acid also needs to be accurate. If it is too little, the product will not precipitate completely, and if it is too much, it may cause the product to be further reacted.
Third, it can also be prepared from a specific halogenated aromatic hydrocarbon through a multi-step reaction. The halogenated aromatic hydrocarbon is substituted with a suitable nucleophilic reagent, a specific group is introduced, and then a series of steps such as oxidation and acidification are carried out to obtain the target product. This approach has many steps, but the reaction route can be flexibly adjusted according to the convenience and cost of the raw materials. The whole process of preparation requires attention to the control of the reaction conditions. The choice of solvent and catalyst is related to the purity and yield of the product and should not be ignored.
In the past market conditions, if the quality of 4-chlorobenzene-1,2-dicarboxylic acid is good, the production and supply are stable and the demand is also flat, and the price may be between [X1] yuan and [X2] yuan per kilogram. However, if there is a loss or a sudden increase in production, the price will rise, and the number can reach [X3] yuan per kilogram. On the contrary, if the production capacity increases greatly, but the demand is not good, the price may fall below [X4] yuan per kilogram.
And the price varies from place to place. In prosperous commercial ports, the transportation is convenient, the flow of goods is smooth, and the price may be relatively flat; while in remote places, the transportation is difficult, and the price will increase.
In addition, the market is unpredictable, and the strategies, policies and decrees of merchants can disturb their prices. In order to know the exact price, when you carefully observe the real-time market conditions, consult the industry, and visit the manufacturers of production and sales, you can get a more accurate number.
