3,5-pyridinedicarboxylic acid, monomethyl ester

3,5-Dimethyladipate monomethyl ester is an organic compound with unique chemical properties.
First, this compound contains two functional groups, carboxyl group and ester group. The ester group is relatively stable in nature, and it is not easy to react quickly with common reagents under normal conditions. However, in the environment of strong bases, the ester group can undergo hydrolysis reaction, which is like a subtle change. Hydroxide ions in strong bases are like brave warriors, attacking the ester group. After the carbonyl carbon of the ester group is attacked, it partially separates from the alcohol to form the corresponding alcohol and carboxylate. This reaction is of great significance in organic synthesis, just like a delicate key, which can open the door to prepare specific carboxylic acids and alcohols.
Second, the carboxyl group is active. It is acidic and can be neutralized with bases, just like the magic of softness. When exposed to alkali substances such as sodium hydroxide, the hydrogen ions in the carboxyl group will leave happily, combine with hydroxide ions to form water, and become carboxylate itself. Not only that, the carboxyl group can also be esterified with alcohols under the catalysis of acid, like a lively party. Under the action of catalysts such as concentrated sulfuric acid, the carboxyl group combines with the alcohol to remove a molecule of water and form new ester compounds. This reaction is a common means of building ester structures in organic synthesis, just like an important building block for building an organic molecular building.
Furthermore, the methyl group in this compound is relatively stable and difficult to react under normal conditions. But in special situations such as specific strong oxidation or light conditions, methyl groups will also be "unwilling to be lonely". Strong oxidants may change the structure of methyl groups like mysterious magicians, triggering reactions such as oxidation, bringing new changes and possibilities to compounds.

The synthesis method of 3,5-dimethylbenzoic acid monomethyl ester is often carried out by ancient methods, and there are three techniques.
One is the method of esterification. First, take 3,5-dimethylbenzoic acid, add an appropriate amount of methanol, and add sulfuric acid as a catalyst. These substances are placed in a reactor, heated to boil, and maintain a reflux state. In this process, the acid and alcohol are esterified to gradually produce 3,5-dimethylbenzoic acid monomethyl ester. After the reaction is completed, the excess acid is neutralized in alkali solution, and then purified by extraction, distillation, etc. The reaction principle is that the carboxyl group of the acid and the hydroxyl group of the alcohol, under the action of the catalyst, remove a molecule of water and form an ester structure.
The second is the acyl chloride method. First, 3,5-dimethylbenzoic acid is co-located with thionyl chloride, and after a little heating, the carboxyl group of the benzoic acid is converted into an acyl chloride group to obtain 3,5-dimethylbenzoyl chloride. Next, take an appropriate amount of methanol and add it dropwise to the system containing 3,5-dimethylbenzoyl chloride, and at the same time add an acid binding agent, such as pyridine. The acid chloride reacts with methanol to quickly produce 3,5-dimethylbenzoic acid monomethyl ester. After the reaction is completed, the desired product is obtained by washing with water, drying, rectifying and other steps to remove impurities and store sperm. The key here lies in the high reactivity of the acid chloride, which is easy to form esters with alcohols.
The method of transesterification. Ethyl 3,5-dimethylbenzoate and methanol are selected as raw materials, and catalysts such as p-toluenesulfonic acid are added. At a suitable temperature, the two substances undergo transesterification reaction, and the ethyl ester group is exchanged with the methyl group of methanol to produce 3,5-dimethylbenzoate monomethyl ester. Afterwards, by means of reduced pressure distillation, the product and the unreacted substance are separated to obtain high-purity 3,5-dimethylbenzoate monomethyl ester. The beauty of transesterification lies in the mild conditions and the ease of purchase of raw materials, which is a commonly used method.

Now there is a market price of 3% 2C5-diethyl diacid monoethyl ester. The market price often changes due to many things, such as the amount of production, the rise and fall of the demand, the difficulty of making it, and the cost of transportation.
If the product is produced in a place where the quantity is large and the demand is not increased, the price may decline. On the contrary, if there are many applicants and there are few products, the price will rise. And if the technique of making this product is complex, it requires more labor and materials, and its price is also high; if it is easy to make, the price may be low.
The cost of transportation is also very high. If the origin is far away from the user, and the cost of transshipment is high, it will also be added to the price. Furthermore, the time is different, and the price is also different. In a good year, the price may be stable or drop; in a poor year, the price will rise when the material is thin.
