What are the chemical properties of 4-chloro-1,2-phthalic acid?
Halide ethane, also known as 1,2-dibromoethane, has the following chemical properties:
Halide ethane has the typical properties of halogenated hydrocarbons. First, substitution reactions can occur. Due to the presence of halogen atoms, the carbon atoms attached to halogen atoms in halogen ethane molecules are partially positively charged and easily attacked by nucleophiles. For example, in aqueous solutions of sodium hydroxide, halogen atoms are replaced by hydroxyl groups to form ethanol and sodium bromide. The reaction formula is: $C_ {2} H_ {5} Br + NaOH\ xrightarrow [] {H_ {2} O} C_ {2} H_ {5} OH + NaBr $. This reaction is often used in organic synthesis to introduce hydroxyl functional groups.
Second, the elimination reaction can occur. In the alcohol solution of sodium hydroxide, haloethane eliminates hydrogen halide to form ethylene. During the reaction, the halogen atom and the hydrogen atom on the adjacent carbon atom are removed under basic conditions to form an unsaturated bond. The reaction formula is: $C_ {2} H_ {5} Br + NaOH\ xrightarrow [] {alcohol} CH_ {2} = CH_ {2}\ uparrow + NaBr + H_ {2} O $. The elimination reaction is one of the important methods for preparing olefins.
Third, haloethane can react with metal magnesium to form Grignard reagents in anhydrous ether environment, namely $C_ {2} H_ {5} Br + Mg\ xrightarrow [] {anhydrous ether} C_ {2} H_ {5} MgBr $. Grignard reagents are widely used in organic synthesis, which can be used to construct carbon-carbon bonds and react with carbonyl compounds such as alcaldes and ketones to form alcohols and other organic compounds.
Fourth, haloethane has certain chemical stability, but under specific conditions such as light or high temperature, halogen atoms may homogenize and produce free radicals, thereby triggering a series of free radical reactions.
In summary, these chemical properties of haloethane make it have many applications in the field of organic synthesis and is an important intermediate in organic synthesis.

What are the main uses of 4-chloro-1,2-phthalic acid?
Halogen, that is, ammonium chloride, is a colorless crystalline or white granular powder with a salty and slightly bitter taste. Its diformate, the main uses are as follows:
First, in the field of medicine, it has the effect of removing phlegm and relieving cough. "Compendium of Materia Medica" says: "Ammonium chloride can remove phlegm and relieve cough, cover its taste and salty, and salty can be soft and firm, so it can reduce phlegm. And its cold nature can clear and relieve lung heat, make lung qi clear and smooth, and cough is self-leveling." In the case of cough with too much phlegm, halogen dicarbonate can stimulate the gastric mucosa, reflect through the vagus nerve, promote the secretion of respiratory tract glands, dilute phlegm, facilitate the discharge, achieve the purpose of removing phlegm, and then relieve cough.
Second, in industry, it can be used as a Tiangong Kaiwu "says:" When dyeing, halogen sand diformate can help the dye better adhere to the fabric, making the color uniform and firm. "Because it can interact with dye molecules, it enhances the bonding force between the dye and the fabric fiber, improves the dyeing quality, and makes the dyed product bright and long-lasting, not easy to fade.
Third, it is also used in agriculture. Halogen sand diformate contains nitrogen elements and can be used as nitrogen fertilizer." Qi Min Yaoshu "says:" This salt can fertilize the soil and nourish crops. "Appropriate application can provide nitrogen nutrients for plant growth, promote plant stem and leaf growth, enhance photosynthesis, and increase crop yield. However, due to its chlorine content, chlorine-free crops such as tobacco and tea should be used with caution to avoid affecting crop quality.

What is the synthesis method of 4-chloro-1,2-phthalic acid?
To make dioxalic acid, the following method can be used.
First take ethylene and add it to bromine water to obtain 1,2-dibromoethane. This step is due to the carbon-carbon double bond of ethylene, which can be added to bromine. Bromine atoms are added to the carbon atoms at both ends of the double bond. The reaction formula is:\ (CH_ {2} = CH_ {2} + Br_ {2}\ rightarrow CH_ {2} BrCH_ {2} Br\).
Then, 1,2-dibromoethane is co-heated with an aqueous solution of sodium hydroxide, and a substitution reaction occurs. The bromine atom is replaced by a hydroxyl group to form ethylene glycol. The reaction formula is:\ (CH_ {2} BrCH_ {2} Br + 2NaOH\ xrightarrow [\ Delta] {H_ {2} O} CH_ {2} OHCH_ {2} OH + 2NaBr\).
Then oxidize ethylene glycol with a strong oxidant, such as an acidic potassium permanganate solution, to obtain dioxalic acid. Because the hydroxyl group in ethylene glycol can be oxidized by potassium permanganate and gradually oxidized to a carboxyl group, in this process, ethylene glycol is oxidized to glyoxal first, and then oxidized to dioxalic acid. The oxidation reaction is more complicated. Take the oxidation of ethylene glycol to dioxalic acid as an example. The approximate reaction formula can be expressed as:\ (5CH_ {2} OHCH_ {2} OH + 8KMnO_ {4} + 12H_ {2} SO_ {4}\ rightarrow 5HOOCCOOH + 8MnSO_ {4} + 4K_ {2} SO_ {4} + 22H_ {2} O\).
Another way can be started from acetylene. Acetylene and water are added under the catalysis of mercury salts to generate acetaldehyde. Acetaldehyde can be oxidized to obtain acetic acid, acetic acid can be converted into monochloroacetic acid through a series of reactions, and monochloroacetic acid can be hydrolyzed and oxidized to obtain dioxalic acid. However, compared with the method of ethylene initiation, this approach is slightly more complicated. Therefore, ethylene is often used as the starting material to prepare dioxalic acid through reactions such as addition, substitution, and oxidation.

What is the price range of 4-chloro-1,2-phthalic acid in the market?
In today's well market, the price of halogen and benzodicarboxylic acid is not always accurate, because it changes due to various circumstances. Looking at the market, the price of the two often varies according to the place of production, age, and supply and demand.
Different production places, their quality and quantity are also different, and their prices are different. If the production place is rich, the production of halogen and benzodicarboxylic acid is quite abundant, and the method of mining is good, its price may be slightly flat; if the production place is remote and difficult to harvest and transport, its price must be high.
Changes over time are also related to the price. If the weather is good, the production of halogen and benzodicarboxylic acid will be prosperous, and the market supply will be sufficient, and the price will stabilize or drop; if there is a disaster, the production will be damaged, and the supply will not be enough, and the price will rise sharply.
The situation of supply and demand is particularly important. At present, halogen and benzodicarboxylic acid are widely used, and they are needed for both work and agriculture. If there are many people who want it, but the supply is limited, the price will rise; if the demand is thin, the supply will be surplus, and the price will be low.
Roughly speaking, the price of halogen is one or two, and its price fluctuates between a few and dozens of texts; the price of benzodicarboxylic acid is about 100 texts, but it is not constant. Or due to changes in market conditions, the price varies over a few days, and merchants must keep an eye on it at any time before they can profit from the market.

What are the precautions in the production process of 4-chloro-1,2-phthalic acid?
The industry of making sea is related to many things. In the production process of diacetic acid, it is especially necessary to pay attention to all things.
First, the selection of raw materials is the key. It is necessary to carefully select high-quality raw materials, which is the foundation for ensuring product quality. If the raw materials are not good, the product is impure, or contains impurities, which affects its performance and use. For example, if you march and fight, if the grain and grass are not refined, how can the soldiers defeat the enemy?
Second, the control of the reaction conditions should not be underestimated. Temperature, pressure, and catalyst dosage all need to be accurate. If the temperature is too high, the reaction will be too fast, or it will be out of control; if the temperature is too low, the reaction will be slow and time-consuming. The same is true for pressure, and improper pressure will affect the reaction rate and balance. Although the catalyst is used in small quantities, it is like a strategist on the battlefield. Only with precise dosage can we strategize and help the reaction proceed efficiently.
Third, the maintenance and cleaning of equipment is a long-term solution. If production equipment is not maintained diligently, it will be damaged from time to time, which will affect the production process. And cleanliness is also important. Unclean equipment, impurities are mixed in, and products are involved. Just like a boat, if the hull is not often repaired and cleaned, it will easily capsize in case of wind and waves.
Fourth, safety precautions are the top priority. This production process may involve dangerous chemicals, and measures such as fire prevention, explosion prevention, and anti-virus are indispensable. Personnel operation requires strict compliance with procedures and must not make mistakes. If safety is lost, the consequences will be unimaginable, such as a prairie fire and unmanageable.
Fifth, quality inspection is carried out throughout. Every step needs to be strictly tested to ensure that the product meets the standards. A little negligence can lead to the entry of substandard products into the market, damage the reputation, and endanger users. It is like a lot of checkpoints, layers of screening, to produce good products.
The above things are the essence of the production of diacetic acid, and must not be taken lightly.
