This substance is an organic compound with a special structure. It is acidic, because of its molecular structure, the presence of a carboxyl group (-COOH), the carboxyl group can ionize hydrogen ions (H 🥰), causing it to be acidic. In aqueous solution, it will partially ionize, generating corresponding carboxylate ions and hydrogen ions, showing the generality of acids.
can neutralize with bases. When encountering sodium hydroxide (NaOH), hydrogen ions in the carboxyl group combine with hydroxyl ions (OH) to form water, generating corresponding carboxylate and water. In terms of the reaction formula: R - COOH + NaOH → R - COONa + H2O (where R stands for 2 - triethylalkyl - 5 - to the rest of its structure of succinic acid).
can also react with some active metals. In the case of metallic zinc (Zn), the hydrogen ions in the carboxyl group are replaced by zinc to generate hydrogen (H 2) and corresponding carboxylates. The reaction formula is: 2R - COOH + Zn → (R - COO) -2 Zn + H 2 ↑.
can also participate in esterification reactions. Under the condition of concentrated sulfuric acid as catalyst and heating, the carboxyl group is dehydrated and condensed with the alcohol hydroxyl group (-OH) to form an ester compound and water. Suppose the reaction with ethanol (C ³ H OH), the reaction formula is: R - COOH + C ³ H OH $\ underset {\ triangle} {\ overset {concentrated sulfuric acid }{=\!=\!=}}$ R - COOC ³ H + H ³ O.
In addition, the alkyl part of the molecular structure of the substance also affects its chemical properties. The alkyl group has a certain electronic effect, or the acidity of the carboxyl group is slightly reduced, but the overall acidity remains. And because there are longer alkyl chains in the molecule, or its solubility in water is affected, relatively speaking, its solubility in organic solvents is better.

To make di- triethylmethyl - 5 - carboxylic acid salts, the ancient method followed many principles, and now it is here.
First, the method of neutralizing acid and base. Take the appropriate acid, if the acid involved in this is mixed with the appropriate amount of base. For bases, such as sodium hydroxide, in the appropriate proportion of the acid and the acid, slowly stir it in a suitable container. In the meantime, the hydrogen ion of the acid combines with the hydroxide ion of the base to form a water molecule, and the acid ion and the cation of the base combine to form a salt. This process requires careful observation of the temperature and rate of the reaction, so as not to make it too hasty or too slow, resulting in impure products. < Br >
Second, by the method of salt metathesis. Find a soluble salt related to the desired salt, and choose another soluble salt to react with it. The anions and cations of the two are exchanged with each other to form new salts. However, it should be noted that one of the new salts generated must be precipitation, gas or weak electrolyte, so that the reaction can be completed to the right. If a soluble carboxylate is mixed with another salt containing a specific cation in the solution, the reaction conditions are controlled to make the new salt out.
Third, the method of reacting a metal with an acid and then reacting with a base. First, take the metal with suitable activity and make it react moderately with the acid to form a salt solution of metal ions. Such as zinc, iron and other metals react with acids to obtain salts of corresponding metal ions. Then, an appropriate amount of alkali is added to this solution to combine the metal ions with the acid ions of the carboxylate to form di- triethylmethyl - 5 - to its carboxylate. In this process, the activity of the metal, the concentration of the acid and the amount of the base must be accurately grasped, otherwise it is difficult to obtain pure products.
To make this salt, each method has its own delicacy, and the producer needs to carefully observe each section and control its conditions to obtain a product with good quality and purity.

In today's world, there are many business roads, and if you want to know the market price of 23ethyl-5-carboxylate, you need to study it in many ways.
In the Guanfu market, the price of this product often changes for many reasons. First, the abundance of raw materials is related to cost. If the raw materials of 23ethyl are in good weather in the production area and the output is full, the price may stabilize and slowly decline; on the contrary, if there is a famine or war, the raw materials are scarce, and the price will rise sharply. Second, the refinement of the craftsmanship is also the key. Sophisticated techniques can increase output and improve quality, making the cost controllable and the price reasonable; while crude methods consume resources, resulting in poor quality and difficult prices. Third, the market demand is booming and the market is weak. If the industry of this product, such as medicine and chemical industry, is prosperous, the demand exceeds the supply, and the price will be high; if the industry is sluggish, the supply exceeds the demand, and the price will fall.
Furthermore, the price is also different depending on the region. In the capital of Dayi, merchants are convergent, and the logistics is convenient, and the price may be slightly flat; while in remote places, transshipment is difficult, and the price must be high. There are changes in taxes and policies, which also have an impact on the price. Light taxes, policy support, cost reduction for industry operators, price or profit; heavy taxes, policy suppression, cost increase, price will rise. < Br >
Therefore, if you want to know the exact price, you should check the condition of raw materials, the progress of craftsmanship, the change of market demand, and the differences in regions and taxes. Consult all merchants and examine the market conditions in detail before you can obtain its approximate price to meet the needs of business.

The storage conditions of 2-triethylmethyl-5-carboxylate are related to many factors and must not be ignored.
This compound is delicate and easily disturbed by external events. First, temperature is important. It should be stored in a cool place to avoid its warmth. If it is at high temperature, the activity of its molecules can change, or cause structural changes, and the medicinal properties can be lost. Such as in the hot season, place it in a cool library, away from the furnace and the sun. Generally speaking, the environment between two and eight degrees Celsius is quite suitable.
Second, the humidity should not be underestimated. The damp and moist gas makes it easy for this salt to absorb moisture. After moisture absorption, it may agglomerate or cause chemical changes. Therefore, when placed in a dry place, it can be supplemented by desiccant to keep the environment dry and free of moisture.
Furthermore, the influence of light is also great. Light contains energy, or causes the reaction of this compound. Under strong light, chemical bonds may break, causing component variation. Therefore, hide in a dark place, or use a light-shielding device, such as a brown bottle, to protect it from light disturbance.
And be separated from other substances to avoid their mixing. Different chemicals may react, damaging their purity and quality. Store separately and in sections to prevent them from disturbing each other.
In short, the storage of 2-triethylmethyl-5-carboxylate needs to be controlled at temperature, kept dry, protected from light damage, and stored alone to prevent impurities, so as to be able to improve its quality and extend its effectiveness. It is also necessary for medicinal use and research.
