4-Dihydroxyethyl aminoethyl glycidyl ether succinate, this is a delicate chemical substance. Its physical properties are particularly critical and related to many practical aspects.
Looking at its properties, under normal conditions, or a clear to slightly colored liquid, with a uniform texture and no obvious impurity suspension, it is like a light, clear and quiet, highlighting its inherent purity.
When it comes to boiling point, under specific pressure conditions, when it reaches a certain temperature, the substance changes from liquid to gaseous state. The number of boiling points is an important indicator of its physical properties, which is related to its stability and transformation conditions under heating environment. The boiling point value varies according to the specific composition and ambient pressure, but they all follow certain physical laws, providing a basis for precise temperature control in industrial applications.
Melting point cannot be ignored either. When the temperature drops to a certain value, the substance solidifies from liquid to solid. The location of this melting point reveals the critical transformation of its morphology at low temperature. During storage and transportation, the temperature needs to be properly regulated according to this characteristic to ensure the stability of its properties.
As for density, the mass per unit volume is just like a measure of the intrinsic compactness of a substance. The value of its density determines its floating state in different media, which affects the distribution and interaction of substances in the mixed system, providing an important reference for process design and practical operation.
Solubility is also a key property. In common organic solvents, it can be well dissolved to form a uniform and stable solution, just like fish entering water and blending freely. This property allows it to play a full role in many chemical reactions and material preparation processes, becoming a powerful assistant for building complex chemical systems and laying the foundation for achieving specific chemical goals.

4-Diethylaminoethoxyhexanoate, this physical property is also, with a variety of characteristics. Its shape, at room temperature, is usually colorless to light yellow transparent liquid, looks like a flowing state, uniform texture, no variegation and foreign matter, like clear water, quiet and transparent.
On its taste, it often has a slight special smell, not pungent, but also clear and discernible, just like a faint fragrance, rippling in the air.
When it comes to solubility, it can blend with many organic solvents, such as alcohols, ethers, etc., just like fish get water, and blend with each other seamlessly. This property makes it widely used in the field of chemical industry, which can be used as a reaction medium and can also assist in the dispersion and mixing of substances.
As for the boiling point, it is about a certain temperature range, and the specific value varies according to its purity. The boiling point state is similar to the boiling of water, and the substance gradually changes from the liquid state to the gaseous state, and the molecular vitality is greatly increased, breaking free from the shackles of the liquid phase.
Its stability is acceptable, and under normal conditions, it is not easy to spontaneously produce violent chemical changes. However, in case of extreme situations such as high temperature and strong oxidants, it is easy to trigger chemical reactions or cause structural changes or property changes when exposed to dry wood from an open flame.
Furthermore, its chemical activity is also considerable. The specific functional groups contained in the molecular structure endow it with unique reaction capabilities. It can undergo condensation reactions with compounds containing active hydrogen, just like tenon and tenon joints, to construct new substances. In the process of organic synthesis, it is like a delicate spoon that opens the door to the preparation of various compounds. It can be used in the fields of medicine, fragrances and other fine chemicals to help the research and development and creation of new products.

To prepare 4-diethylaminoethoxybenzaldehyde, the method is as follows:
First take an appropriate amount of raw materials and put them in a suitable reaction vessel. Resorcinol can be reacted with diethylaminochloroethane hydrochloride in an alkaline environment. In the reaction system, a base is slowly added to adjust the pH value to achieve a suitable alkaline range. Generally, the pH value should be maintained in a certain range. This range needs to be precisely adjusted according to the specific reaction conditions, generally around 8-10. The reaction temperature is also a key factor and needs to be controlled within a certain temperature range, which can be maintained between 50-70 ° C. The heating method can be heated in a water bath to make the heating uniform and avoid local overheating and side reactions. Under these conditions, the nucleophilic substitution reaction occurs between the two. The phenolic hydroxyl oxygen atom of resorcinol acts as a nucleophilic reagent to attack the α-carbon atom of diethylaminochloroethane hydrochloride, and the chlorine atom leaves to form an ether-linked intermediate.
After the reaction is completed, the resulting intermediate is further processed. Oxidation with a specific oxidant, such as manganese dioxide, a mild oxidant, is carried out in a suitable solvent. Solvents can be selected such as dichloromethane, which has good solubility to the reaction substrate and product, and its properties are relatively stable. The reaction temperature can be slightly adjusted to maintain at 20-30 ° C. This temperature can not only ensure the smooth progress of the oxidation reaction, but also reduce side reactions such as excessive oxidation. After the oxidation step, the phenolic hydroxyl group of the intermediate is oxidized to the aldehyde group, thereby preparing 4-diethylaminoethoxybenzaldehyde.
After the reaction is completed, the product needs to be separated and purified. First, the organic phase is separated from the reaction mixture by the method of liquid separation, and then the organic phase is dried with a desiccant such as anhydrous sodium sulfate to remove the residual moisture. Afterwards, the pure 4-diethylaminoethoxybenzaldehyde is separated by the method of reduced pressure distillation according to the boiling point difference between the product and the impurity, and the corresponding boiling point fraction is collected to obtain a high-purity product. The whole process requires fine control of the reaction conditions and separation steps to ensure the yield and purity of the product.

The price of 4-diethylaminoethoxyhexanoic acid in the market is not fixed. The price involves various reasons, such as the cost of production, the state of demand and supply, the competition in the market, and the control of regulations.
On the cost of its production, the price of raw materials, labor costs, and equipment consumption are all factors. If the price of raw materials is high, or the labor costs are heavy, and the demand is huge, the cost of its production will increase, and the price will also rise.
The state of demand and supply is also large in the shadow of the price. If there are many applicants and few suppliers, the price will often increase; if the supply exceeds the demand, the price may decline.
The competition in the city is also the main point. The competition among the same industry is intense, in order to occupy the market share, there may be a policy to cut the price, and the price may change accordingly.
The control of regulations should not be ignored. The regulations and laws of the government have regulations on production, sales and prices, or the prices are different.
Basically speaking, the price may be between tens of yuan per kilogram and hundreds of yuan per kilogram. However, this is only an approximate number, and the actual price must be determined according to time, place and circumstances. To know the exact price, the manufacturers and merchants in the market can only obtain it after detailed consultation.
