What are the physical properties of Benzeneacetic Acid, Alpha-chloro-4-methyl-, Methyl Ester
"Tiangong Kaiwu" is a masterpiece of ancient Chinese science and technology, but it does not involve this thing, so I will use today's academic words to describe the physical properties of this thing for you.
This "α-chloro-4-methylphenylacetate methyl ester" is mostly liquid at room temperature, and it is clear and transparent when viewed, and has a slightly special smell. Its density is slightly higher than that of water. When placed in water, it will sink to the bottom of the water. The boiling point is within a certain range. When heated at this temperature, it will boil and transform into a gaseous state.
This substance has good solubility in organic solvents, such as ethanol, ether, etc. Due to the principle of similarity and miscibility, its molecular structure is compatible with organic solvents. However, its solubility in water is very small, because its molecular polarity is quite different from that of water.
In addition, this substance has a certain degree of volatility, and in the air, the molecules will gradually dissipate. It is more sensitive to light, and long-term light exposure may cause it to undergo chemical reactions, resulting in changes in structure and properties. Its refractive index has a specific value, which is an important physical parameter for the identification and analysis of this substance, which can help researchers determine its purity and characteristics.
The above is a common physical property of "α-chloro-4-methylphenylacetate" for your reference.

What are the chemical properties of Benzeneacetic Acid, Alpha-chloro-4-methyl-, Methyl Ester
On a certain evening, a scholar studied a thing called "Benzeneacetic Acid, Alpha-chloro-4-methyl -, Methyl Ester", which is an organic compound to clarify its chemical properties.
Its physical properties are colorless to light yellow liquid at room temperature, with a special smell. Looking at its melting point, the melting point is low, and the boiling point varies according to the ambient pressure, usually boiling at a certain temperature range. In terms of solubility, it is insoluble in water, but it can be mutually soluble with most organic solvents, such as ethanol, ether, etc. Just like the difficulty of oil and water, it is similar to similar organic solvents.
In terms of its chemical activity, due to the chlorine atoms in the structure, α-carbon is quite active, and it is easy to be attacked by nucleophilic reagents and undergo nucleophilic substitution reactions. In case of alcohol nucleophilic reagents, chlorine atoms may be replaced by alkoxy groups to form new ester compounds. And its benzene ring structure is stable, but it can also participate in the reaction under specific conditions. If under the action of a catalyst, the substitution reaction on the benzene ring can occur, and halogenation, nitrification, and sulfonation are all possible. It is like finding a breakthrough on a solid barrier and a chemical transformation occurs.
Its ester group part also has unique reactivity. Under acidic or basic conditions, hydrolysis can occur. In acidic hydrolysis, α-chloro-4-methylphenylacetic acid and methanol are formed; in alkaline hydrolysis, the corresponding carboxylic salts and methanol are formed, and this hydrolysis process is like the disassembly and remodeling of ester structures.
The chemical properties of this compound are widely used in the field of organic synthesis, and can be used as an intermediate. After a series of reactions, a variety of organic compounds are obtained. It has potential value in the fields of medicine, pesticides, fragrances, etc., and is like the key to opening many doors to chemical synthesis.

Benzeneacetic Acid, Alpha-chloro-4-methyl-, Methyl Ester
The method of preparing methyl α-chloro-4-methylphenylacetate has been used in ancient times, and is detailed as follows.
Take 4-methylphenylacetic acid as the starting material, which is easily available in the market or synthesized by other methods. Place 4-methylphenylacetic acid in a suitable reactor, which needs to be cleaned and dried to prevent impurities from disturbing it.
Add an appropriate amount of chlorinated reagents, such as phosphorus oxychloride, sulfoxide chloride, etc. Sulfoxide chloride is often preferred because of its high reactivity and few side reactions. After adding, slowly raise the temperature, and control the temperature within a specific range. This range depends on the reagents used and the reaction characteristics, about 50-80 degrees Celsius. During this period, stir well to make the reaction sufficient.
Sulfoxide chloride reacts with 4-methylphenylacetic acid to form α-chloro-4-methylphenylacetic acid. During this step of the reaction, hydrogen chloride and sulfur dioxide gas escape, and a proper exhaust gas treatment device needs to be set up to protect the environment and personal safety.
After the chlorination reaction is completed, cool down to room temperature. Next, mix the obtained α-chloro-4-methylphenylacetic acid with methanol, and add a little sulfuric acid as a catalyst. The amount of sulfuric acid needs to be carefully controlled, and excessive amounts will lead to side reactions.
Heat up to 60-80 degrees Celsius, and perform esterification reaction. During this step of reaction, the generated water and methanol form an azeotrope escape system, which prompts the reaction to proceed towards the formation of α-chloro-4-methylphenylacetate.
After the reaction is completed, cool the reaction solution. Neutralize in sodium bicarbonate solution to remove residual sulfuric acid. Then separate the organic phase with a separation funnel, wash it with water several times, and remove salts and water-soluble impurities.
After drying the organic phase with anhydrous sodium sulfate, filter out the desiccant. Distillation under reduced pressure to obtain a specific boiling range fraction, which is methyl α-chloro-4-methylphenylacetate.
This method is optimized by various experiments, and can obtain products with high yield and purity. It has practical value in industrial production and laboratory preparation.
