3,4-Diethoxydiacetic acid, mild in nature, is a colorless and transparent liquid in normal state, with a specific fragrant smell. Its melting degree is quite low, about - 20 ° C. This characteristic makes the substance constantly liquid at room temperature, easy to access and participate in various chemical reactions. The boiling point is in a relatively high range, about 230 ° C - 240 ° C, indicating that the substance has good thermal stability and begins to evaporate at higher temperatures.
Its density is about 1.1 g/cm ³, which is slightly heavier than water. If it is co-located with water, it will sink to the bottom of the water. And the miscibility of this substance with water is limited, only slightly soluble in water, but it can be miscible with many organic solvents, such as ethanol, ether, acetone, etc., in any ratio. This characteristic makes it in the field of organic synthesis, often used as an excellent reaction medium or extraction solvent.
Because its molecular structure is rich in ester functional groups, its chemical properties are active, and it can participate in many organic reactions such as hydrolysis, alcoholysis, and aminolysis. During hydrolysis, in the catalytic environment of acids or bases, the ester groups are disconnected to form corresponding alcohols and acids; in the alcoholysis reaction, it can exchange reactions with other alcohols to form new esters; when ammonolysis occurs, amide products are formed. All these reactions make 3,4-diethoxydiacetic acid have a wide range of application prospects in many industries such as medicine, fragrances, coatings, etc., and can be called an indispensable and important raw material in the field of organic synthesis.

The chemical properties of 3% 2C4-pentadienedioic acid are still stable at room temperature and pressure. However, in case of hot topic, open flame or strong oxidant, there is a risk of violent reaction.
This compound contains a conjugated double bond structure, which gives it unique chemical activity. The existence of the conjugated system allows the electron cloud to be delocalized, which affects its reactivity. It can participate in a variety of addition reactions, such as the Diels-Alder reaction with dienophiles, which is an important organic reaction for constructing carbon-carbon bonds. Due to the special electronic structure of the conjugated double bond, the reaction is more prone to occur.
Furthermore, the presence of carboxyl groups is also a key factor affecting its chemical properties. Carboxyl groups are acidic and can neutralize with bases to generate corresponding salts and water. In organic synthesis, this property can often be used to derive them to prepare various esters, amides and other derivatives.
However, its stability is also significantly affected by environmental factors. High temperature can increase the intramolecular energy, making chemical bonds more easily broken, which in turn triggers decomposition reactions. The presence of strong oxidants may oxidize some groups in the molecule, changing their chemical structures and properties. Therefore, when storing and using, it is necessary to properly avoid heat and strong oxidants to ensure the relative stability of its chemical properties and avoid the occurrence of accidental chemical reactions.

3,4-Dimethyladipic acid is an organic compound and is widely used in the chemical industry. There are several common methods for its preparation:
First, olefin is used as the starting material. Take a specific olefin and make it hydroformylated with carbon monoxide and hydrogen under suitable catalyst and reaction conditions to obtain aldehyde intermediates. Later, the aldehyde product is oxidized to convert it into the corresponding carboxylic acid, thereby obtaining 3,4-dimethyladipic acid. In this path, the key to the hydroformylation reaction lies in the selection of efficient catalysts, such as rhodium or cobalt catalysts, to promote the efficient progress of the reaction and improve the selectivity of the target product. In the oxidation step, the type and dosage of the oxidizing agent need to be considered. Common oxidizing agents include oxygen, hydrogen peroxide, etc., to ensure that the aldehyde can be fully oxidized into carboxylic acids.
Second, it is prepared by halogenated hydrocarbons. First, the halogenated hydrocarbon is reacted with metal magnesium to prepare Grignard's reagent. Grignard's reagent has high activity and can react with carbon dioxide to form carboxylic salts, which are then acidified and converted into carboxylic acids. If halogenated hydrocarbons with suitable structures are selected, 3,4-dimethyladipic acid can also be prepared according to this reaction sequence. When preparing Grignard's reagent, the reaction environment needs to be strictly anhydrous and oxygen-free, otherwise Grignard's reagent is easy to decompose and affect the reaction process. And in the acidification step, the
Third, biosynthesis. Some microorganisms have specific metabolic pathways and can use specific carbon and nitrogen sources to synthesize 3,4-dimethyl adipic acid through their own metabolic activities. This method is green and environmentally friendly, and the conditions are relatively mild. However, the screening and culture requirements for microorganisms are strict. It is necessary to find strains that can efficiently synthesize the target product, and optimize the culture conditions, such as controlling temperature, pH value, nutrient concentration, etc., to improve the yield and purity of the product.

In today's market, the price of ethyl 3,4-dihydroxybutyrate is uncertain, and it mostly varies with the supply and demand of the market.
I have heard that this product has different uses in various fields, and its price is also different. In the pharmaceutical preparation industry, those who need high purity have a high price. This is because pharmaceuticals are related to human life, the materials used must be strict, and the purification technique is also complicated, so it is worth thousands of gold. Or the price per gram can reach tens of gold, or even hundreds of gold, depending on its purity grade.
If it is used in chemical research, the purity requirement is slightly reduced, and the price is also slightly reduced. Each gram or a few gold can range from ten to twenty gold. However, there are many chemical materials, and if you buy them in bulk, the total price will be huge.
As for ordinary industrial uses, the purity is lower, and the price is also cheaper. It's only a few dollars per gram or a few dollars.
In addition, the distance of the origin and the stability of the current situation are all related to the price. The production place is close and the transportation is convenient, and the price may be slightly flat; the current situation is turbulent, the logistics is not smooth, and the price may rise. And the state of supply and demand in the market is also the key to the price. If there are many seekers and few suppliers, the price will rise; if the supply exceeds the demand, the price will fall. < Br >
Therefore, in order to know the exact price of ethyl 3,4-dihydroxybutyrate, it is necessary to carefully check the current market conditions, purity requirements, purchase quantity and other things before obtaining it.
