N-dimethylacetamide is a crucial organic solvent in the chemical industry. Its main uses are as follows:
bears the brunt and is of great significance in the field of synthetic fiber production. In the dry spinning process of acrylic fibers, N-dimethylacetamide acts as a solvent to dissolve polyacrylonitrile. With its excellent solubility, polyacrylonitrile can be uniformly dispersed, and then high-quality acrylic fibers can be spun. The resulting fibers have many advantages such as high strength, soft feel and good wrinkle resistance. For example, the production of acrylic fabrics commonly used in the textile industry cannot be separated from N-dimethylacetamide.
Furthermore, it also plays a key role in the field of plastics processing.

In summary, N-dimethylacetamide plays a key role in many industrial fields due to its unique physical and chemical properties, and has far-reaching significance in promoting the development of various industries.

N% 2C N-dimethylacetamide is a common solvent in organic chemistry, and its physical properties are quite unique.
Looking at its properties, under normal temperature and pressure, this substance is a colorless and transparent liquid, like clear water, and the smell is slight, just like the gentle breeze.
When it comes to boiling point, the boiling point of N% 2C N-dimethylacetamide is quite high, about 164.5 ° C. Such a high boiling point allows it to maintain a liquid state in a relatively high temperature environment and has good stability. This property is crucial in many chemical processes that require high temperature reactions, ensuring the stability of the reaction system and providing a suitable environment for chemical reactions.
As for the melting point, it is about -20 ° C. The lower melting point means that the substance is always in a liquid state near room temperature, making it easy to use and operate, which brings many conveniences to experiments and industrial production.
Its density is about 0.94 g/cm ³, which is slightly lighter than that of water. In some operations involving stratification or mixing, this density characteristic determines its location and distribution in the system, and has a non-negligible impact on the reaction process and product separation.
Solubility is also one of its important physical properties. N% 2C N-dimethylacetamide can be miscible with water and most organic solvents such as ethanol and ether in any ratio. This excellent solubility makes it a good solvent for many organic compounds. Whether it is a polar compound or a non-polar compound, it has a certain solubility in it, so it is widely used in organic synthesis, polymer material preparation and other fields, which can effectively promote the contact and reaction of the reactants.
In addition, the viscosity of the substance is relatively low and the fluidity is good. This property is conducive to reducing energy loss and improving production efficiency in pipeline transportation, stirring and mixing operations. And because of its good fluidity, the reactants can be dispersed more uniformly in chemical reactions, thereby improving the uniformity and efficiency of the reaction.

N, N-dimethylacetamide has mild properties and is a commonly used solvent in organic synthesis. Looking at its physical properties, it is a colorless and transparent liquid with a weak amine taste at room temperature, with a high boiling point of about 166.1 ° C. This characteristic makes it stable in high temperature reaction systems, and it is not easy to evaporate and dissipate, ensuring a constant reaction environment. Its melting point is low, about -20 ° C, so it is easy to use and operate under normal conditions. In addition, its density is moderate, 0.9429g/cm ³, which is suitable for many organic compounds, making it easy to mix and react.
When it comes to chemical properties, N, N-dimethylacetamide has good solubility and can be miscible with water and most organic solvents such as ethanol, ether, benzene, etc. in any ratio. This is because of the synergistic effect of carbonyl and dimethylamino in its molecular structure, so that the molecule has certain polar and non-polar parts, allowing it to interact with solvents of different properties. This property makes it an excellent reaction medium in the field of organic synthesis, which can dissolve various reactants and promote the smooth progress of the reaction.
Furthermore, the chemical properties of N, N-dimethylacetamide are relatively stable, and it is not easy to hydrolyze and oxidize under general conditions. However, in the presence of strong acids, strong bases or specific catalysts, it can also participate in specific chemical reactions. For example, when encountering strong acids, its carbonyl groups can protonate, which in turn affects the reactivity of molecules; when encountering strong bases, dimethylamino groups may be attacked, triggering a series of chemical changes. But overall, in the conventional organic synthesis operating environment, its stability is sufficient to ensure the reliable progress of the reaction, providing a solid foundation for the synthesis of many complex organic compounds.

When preparing N, dimethylethanolamine, pay attention to many key matters.
The first thing to pay attention to is the quality of the raw materials. The raw materials are pure and have few impurities to ensure the quality and yield of the product. If the raw materials are not good, or the reaction by-products increase, the purity of the product decreases, and subsequent purification becomes more difficult.
The control of the reaction conditions is crucial. In terms of temperature, it is necessary to strictly maintain a suitable range. If the temperature is too low, the reaction rate is slow and time-consuming; if the temperature is too high, it is easy to cause side reactions and reduce the selectivity of the product. For example, a specific reaction is suitable for a certain precise temperature range, and a slight deviation affects the reaction process and results. The same is true of pressure. Appropriate pressure provides a suitable environment for the reaction, or it is related to the state and direction of the reactants. Improper pressure may cause the reactants to fail to effectively contact the reaction, or affect the proportion of product formation.
The choice and dosage of catalyst should not be underestimated. High-quality catalysts can significantly accelerate the reaction rate and reduce the activation energy of the reaction. However, the amount of catalyst needs to be precise. If the amount of catalyst is too small, the catalytic effect will be poor, and too much or cost will increase, which may also affect the reaction selectivity.
The monitoring and regulation of the reaction process is also the focus. With modern analytical methods, the reaction process can be monitored in real time, such as the consumption of reactants and the amount of product generated. According to the monitoring results, the reaction conditions If the reaction is off track, the temperature, pressure, or reactants can be changed in time to get the reaction back on track.
Safe production and environmental protection should not be taken lightly. N, The preparation process of dimethylethanolamine or involving dangerous chemicals must be operated in strict accordance with regulations to ensure the safety of personnel and the environment is not polluted. Complete protective facilities and proper disposal of waste are all indispensable links in production.

Today, there is N% 2C N-dimethylethanolamine, what is the market situation? This is a commonly used material in the chemical industry, and its reason is as follows.
One of them is the main reason for the location. If it is a place where there are abundant sources and high-quality workers, the cost may decrease due to the convenience of excavation and extraction, and the cost will also be low. On the contrary, where there is a lack of sources and high-quality workers, the cost will be high.
Second, the supply and demand of N% 2C N-dimethylethanolamine is low. The demand for N% 2C N-dimethylethanolamine in the market is strong, but the supply is limited. If the demand is low, the supply will be left, and the price will fall.
Third, the difference between the high and low quality of the product. Those with high quality, low cost, high cost, high cost, and high cost of use, are not expensive; those with poor quality, low cost.
Fourth, the storage cost of this product also has an impact. This chemical product requires special products. If the cost increases, the cost will also increase.
Generally speaking, the market price fluctuates between 1,000 and 40 yuan per year. However, if you want to know the exact price, you can only get it by looking at the market conditions and suppliers.
