(This text seems to contain garbled or incomplete expressions, and the "2-%28%E4%B8%89%E6%B0%9F%E7%94%B2%E5%9F%BA%29-3-%E5%90%A1%E5%95%B6%E7%BE%A7%E9%85%B8%E4%B9%99%E9%85%AF" part cannot be clarified. The following answer is based on reasonable speculation.)
The substances of triethyl are particularly interesting in their chemical properties. These substances, or reactive, can often play an important role in various chemical reactions.
As for triethyl-related esters, such as triethyl ethyl acetate, their properties also have their own characteristics. Its physical properties, or colorless and transparent liquids, have a certain degree of volatility and can be gradually emitted in the air. And its smell, or a special fragrance, although not rich and pungent, it is also clearly identifiable.
In terms of chemical properties, triethyl ethyl acetate can react with many reagents. In the case of strong basic substances, or hydrolysis, its ester bonds are broken to form corresponding alcohols and carboxylic salts. This hydrolysis process may require specific temperatures and reaction conditions to proceed smoothly.
Or it can undergo nucleophilic substitution reactions with some nucleophilic reagents, and its reactivity is affected by the electronic and spatial effects of the groups in the molecular structure. If the surrounding groups have electron-pushing effects, the reactivity can be changed, accelerated, or slowed down, depending on the specific situation.
In the field of organic synthesis, triethyl acetate is often an important intermediate. Due to its unique chemical properties, chemists can use ingenious design to transform it into various complex organic compounds, which are of great application value in many industries such as medicine and materials.

To prepare ditriethyl-3-pentenyl butyrate ethyl ester, the method is as follows:
The first is to prepare the raw materials. Triethyl, suitable halopentene and alkali substances are required. For triethyl, that is, ethyl triacetate, halopentene is selected according to its structure, and the pentene derivative suitable for halogen atom substitution is selected, and the base can be selected as sodium alcohol, such as sodium ethyl alcohol, which can create an alkaline environment in the reaction system and help the reaction to proceed.
The second is the operation of the reaction. Mix triethyl and base in an appropriate amount of organic solvent, often with anhydrous ether or toluene as the solvent. The two have good solubility to the reaction raw materials and products, and are stable in nature and do not disturb the main reaction. The alkali into triethyl can capture the hydrogen of triethylene active methylene and generate carbon negative ions. This is the key intermediate for the reaction and has strong nucleophilicity.
Then, slowly add halopentene to the above mixed system. The carbon connected to the halogen atom of halopentene is positively charged. If the carbon negative ion attacks nucleophilic, it forms a carbon-carbon bond to obtain an intermediate containing the target carbon skeleton. This step requires temperature control to prevent side reactions from occurring. Usually low temperature is appropriate, such as 0-5 ° C, so that the reaction can proceed in the main reaction direction.
After the reaction is completed, neutralize the system with an acid, such as dilute hydrochloric acid. Neutralize the unreacted base to make the system neutral or weakly acidic and stabilize the product. Subsequent to the conventional separation and purification methods, such as extraction, distillation, column chromatography, etc. Extraction can be divided into the organic phase and the aqueous phase, so that the product is enriched in the organic phase; distillation according to the boiling point difference of each component, separation of the product and low boiling point impurities; column chromatography according to the principle of adsorption and elution, further purify the product to obtain high-purity ditriethyl-3-pentenyl butyrate ethyl ester.

(Sanxiang methyl) -3-diethyl carboxylate is indeed used in many fields. In the field of medicine, this compound can be used as a key intermediate for the synthesis of specific drugs. Because it has a unique chemical structure, it can react precisely with other substances to construct a molecular structure with specific pharmacological activities. Therefore, when creating antibacterial and anti-inflammatory drugs, it is often selected as a starting material to synthesize finished drugs with curative effects through a series of chemical reactions.
In the field of materials science, (Sanxiang methyl) -3-diethyl carboxylate is also useful. Due to its active chemical properties, it can participate in polymerization reactions and become a basic unit for the synthesis of new polymer materials. The synthesized polymer materials may have special physical properties, such as excellent flexibility and heat resistance, and are then used in the manufacture of high-performance plastics, fibers and other materials, and are widely used in aerospace, electronic and electrical industries.
Furthermore, in the field of organic synthetic chemistry, it is an important organic reagent and provides an effective path for the synthesis of many complex organic compounds. Chemists can design and implement various organic synthesis reactions by virtue of its unique reactivity, expand the variety and structure of organic compounds, and provide rich raw materials and intermediates for chemical research and industrial production.

"Tiangong Kaiwu" says: "In the world, those who discuss prices often depend on supply and demand, and change with time and place." Today's discussion of the market price of di- (trimethyl) -3-aminobutyric acid ethyl ester should also follow this path.
The price of this product depends first on the balance between supply and demand. If there are many people in the world who want it, but there are few people who produce it, the price will rise. Those who cover demand compete, and those who supply are curious, and the price will be high. On the contrary, if supply exceeds demand, and the stock is difficult to sell, the price will be depressed.
Secondly, the difference of time and place also makes the price different. The change of time is related to the abundance of property. If it is a good year, the product is abundant, and the price may be slightly lower; if it is a disaster year, the product is rare and expensive, and the price will be high. The distance of the land and the difference between water and land also have an impact. Goods near are easy to transport and cost-effective, and the price may be low; goods far away are difficult to transfer, and the cost is high. And in different places, or there are special products, the difference between supply and demand makes the price different.
Furthermore, the difficulty of the process also affects the price. If the preparation method is complicated and requires fine skills and good materials, the cost will be expensive; if the production method is simple and the materials used are ordinary, the cost will be saved and the price will be low.
There are also business people's plans, which are also related to the price. Those who are good at dealing with changes in time, reviewing supply and demand, and being able to set prices according to the situation. Or hoarding goods to wait for the price, or making small profits but quick turnover, are all tricks of business, which make the price change.
Therefore, the market price of ethyl (trimethyl) -3 -aminobutyrate often changes due to supply and demand, time and place, technology, business planning, etc., and cannot be generalized. It is necessary to observe carefully in the market to know the actual price.

The storage conditions of acetamide triethyl-3-pentenedioic acid are as follows: This substance should be placed in a cool, dry and well-ventilated place to avoid open flames and hot topics. Because of its flammability, it can cause combustion in case of open flames and hot topics, so fire prevention is essential.
Furthermore, it needs to be stored separately from oxidants, acids, alkalis, etc., and must not be mixed. This is because the substance encounters with the above-mentioned various chemicals, or causes violent chemical reactions, resulting in danger.
Storage containers must be well sealed to prevent leakage. And suitable materials should be prepared to contain leaks, so that in the event of an accident, they can be dealt with quickly and minimize harm. In addition, there should be obvious warning signs in the storage place, so that everyone is aware of the danger and treat it with caution. In this way, the safety of the storage of the substance should be guaranteed.
