To prepare ethyl 3 - (triethylamino) butyrate, there are various methods, which are listed below:
First, take ethyl 3-halobutyrate and triethylamine as materials, add alkalis such as potassium carbonate and sodium carbonate to appropriate solvents such as acetonitrile and DMF, heat up and reflux, and the halogen ions leave, thus becoming the target product. This reaction condition is peaceful and convenient to operate, but halogenated ethyl butyrate is rare, and there are side reactions, and the yield is not ideal. The reaction mechanism is nucleophilic substitution, the nitrogen of triethylamine has lone pairs of electrons, the nucleophilic attack alpha-carbon of halogenated ethyl butyrate, and the halogen ions leave.
Second, starting with ethyl acrylate and triethylamine, in the presence of free radical initiators such as AIBN, the radical addition reaction is carried out. The double bond of ethyl acrylate is attacked by free radicals, forming carbon free radicals, which combine with triethylamine, and then convert to the target. The raw materials are easy to purchase and the reaction conditions are easy to control. However, the selectivity of the free radical reaction is poor, and the product or impurities need to be carefully separated.
Third, with 3-oxoethyl butyrate and triethylamine as groups, and reducing agents such as sodium borohydride, lithium aluminum hydride, etc., the carbonyl group is first reduced to a hydroxyl group, and then converted through a series of elimination and rearrangement. However, reducing agents such as lithium aluminum hydride have high activity, so the operation needs to be careful, and the reaction environment is demanding, and the post-treatment is complicated.
Fourth, starting with succinic anhydride and triethylamine, the ring is first opened to form triethylamine succinic acid salt, and then prepared by esterification, reduction, elimination and other steps. There are many steps in this diameter, but the raw materials are common. If the reaction conditions of each step are properly optimized, satisfactory results can also be obtained.
The method of preparing ethyl 3- (triethylamino) butyrate has its own advantages and disadvantages. When implementing, it should be selected according to factors such as raw material availability, reaction conditions, product purity and yield.

In today's world, the market price trend of triethylamino-4-carboxyl is really related to many reasons. It is widely used in the chemical industry, so the state of market supply and demand is the main reason for its price.
If the industry that needs this material is booming, the demand for triethylamino-4-carboxyl is greatly increased, and the supply is difficult to follow the demand for a while, the price must rise. On the contrary, if the development of related industries is sluggish, the demand is sharply reduced, and the supply is abundant, the price will easily decline.
Furthermore, the price of raw materials also has a significant impact. If the price of the raw materials required for the preparation of triethylamino-4-carboxyl group increases, the merchant will raise the price of triethylamino-4-carboxyl group in order to ensure profits; if the price of raw materials falls, the cost will drop, and the market price may also drop accordingly.
In addition, policies and regulations and market competition should not be underestimated. Policies encourage the development of related industries, or are conducive to their market expansion, which supports prices; if the market competition is fierce, merchants will compete for shares, or they will use price reduction as a strategy to make their market prices fall.
Looking at the recent market, if there are no major changes, the demand is stable and the raw material price is stable, the market price of triethylamino-4-carboxyl may be stable and rising. Due to the continuous progress of the chemical industry, the demand for this material may increase slowly. However, if there is no significant release of new production capacity, the supply can remain relatively stable, so the price has a basis for upward movement. However, the market situation is changing, and many factors are intertwined, and the price is difficult to be completely determined. It is still necessary to pay close attention to the dynamics of all parties to know the details of its trend.

The physical properties of tris (triethylamino) -4-carboxyl groups are as follows:
This compound contains a triethylamino carboxyl group. In the triethylamine group, the nitrogen atom has solitary ions, which makes it unique and can form acid reactions. In aqueous solution, the triethylamine group can accept particles, which increases the degree of solution.
And the carboxyl group is acidic, which can partially decompose particles in water, making the solution acidic. The degree of its solution is affected by the pH value of the solution. When the pH increases, the degree of carboxyl solution increases; when the pH decreases, the solution is inhibited.
Solubility Look, because of the same water-containing carboxyl group and triethylamine group with certain lipid properties, it has a certain solubility in water, and may also have good solubility in partially soluble compounds such as ethanol and acetone. This property is taken from the interaction of soluble compounds.
In terms of reactivity, carboxylic groups can be esterified and reacted, and alcohols can form esters under the catalytic action; they can also be reacted to form carboxylic acids. Triethylamino groups can be nucleated and substituted for reactivity, etc., because the solitons of nitrogen atoms are easy to attack.
The physicochemical properties of this compound make it useful in the fields of synthesis, physicochemistry, and so on. It can be used for multiple reactions, and its acid and solubility properties provide a basis for its use in different reactions and systems.

When storing and transporting tris (trihydroxymethyl) aminomethane-4-carboxylate, pay attention to many matters.
When storing, the temperature and humidity of the environment are the first priority. This substance should be stored in a cool, dry place to avoid high temperature and humidity. High temperature can easily cause its chemical properties to change, and humidity may cause it to deliquescence, which will damage the quality. If placed in a place with high temperature, such as a warehouse under direct sunlight in summer, it may cause material decomposition, reducing purity and activity; while in a humid environment for a long time, moisture intrusion, or agglomeration of the substance will affect the subsequent use and use effect.
Secondly, attention should be paid to the storage container. It needs to be packed in a container with good sealing performance to prevent excessive contact with the air. Due to the oxygen, carbon dioxide and other components in the air, or chemical reactions with the substance. For example, carbon dioxide may react with some of these components to change its pH, thereby affecting its chemical stability.
As for transportation, shock resistance is one of the keys. During transportation, vibration is too severe, or the packaging is damaged, which in turn causes material leakage. And vibration may also have a subtle impact on the internal structure of the material, changing its properties. For example, on the transportation route with poor road conditions, if there are no proper shock absorption measures, frequent bumps or packaging breaks, endangering transportation safety and material quality.
At the same time, the environment of the transportation vehicle also needs to meet the requirements. Keep the inside of the transportation tool dry and clean, and avoid mixing with other chemicals. If it is transported with chemicals that are contrary to the nature, or cause violent chemical reactions, it will cause serious accidents. Such as mixing with strong oxidants, or causing combustion, explosion and other hazards due to redox reactions.
