Fudimethylaminoacetonitrile is an important intermediate in organic synthesis. Its preparation method has been explored by many scholars in the past, and it is briefly described as follows today.
First, the method of using diethylamine and chloroacetonitrile as raw materials. Diethylamine meets chloroacetonitrile, and the two are combined in the phase. After the nucleophilic substitution reaction, dimethylaminoacetonitrile can be obtained. In this reaction, the nitrogen atom of diethylamine is nucleophilic, while the chlorine atom of chloroacetonitrile is active and easy to be replaced. The reaction conditions must be carefully controlled, and the temperature, the proportion of reactants, and the reaction time are all related to the yield. If the temperature is too high, side reactions will occur; if the ratio is not appropriate, it When the reactants, such as ethanol and acetone, are dissolved in a suitable solvent, the reaction proceeds uniformly, and the properties of the solvent also affect the reaction rate and selectivity.
Second, the method of using dimethylamine and acrylonitrile as raw materials. Dimethylamine and acrylonitrile can be prepared by addition reaction. This addition reaction requires the help of catalysts. Common catalysts such as basic substances can activate the double bond of acrylonitrile, making it easier to react with dimethylamine. During the reaction process, it is crucial to control the pH, temperature and pressure of the reaction system. A suitable alkaline environment can accelerate the reaction, but the alkalinity is too strong, or other side reactions of acrylonitrile can occur, which affects the purity of the product. Temperature and pressure are also related to each other. Reasonable regulation of the two can make the reaction proceed efficiently and increase the amount of product generated.
Third, the method of using ethanolamine, formaldehyde and hydrocyanic acid as raw materials. Ethanolamine is condensed with formaldehyde first, and then reacted with hydrocyanic acid to obtain dimethyl aminoacetonitrile. This route step is slightly complicated, but the raw material is easy to obtain. During the condensation reaction, it is necessary to pay attention to the proportion of reactants and reaction conditions to ensure the formation of condensation products. Subsequent reactions with hydrocyanic acid, hydrocyanic acid is toxic, and the operation must be cautious, and the control of reaction conditions is related to the quality and yield of the product. It is necessary to carry out the reaction smoothly at a suitable temperature and in the presence of a catalyst, and at the same time take
The above preparation methods have their own advantages and disadvantages. When synthesizing, according to the actual situation, such as the availability of raw materials, cost, product purity requirements, etc., choose the best one and use it to achieve the purpose of preparing dimethylaminoacetonitrile.

Dimethylaminoacetonitrile, also known as 2- (dimethylamino) acetonitrile, has the following physical properties:
This substance is a colorless to light yellow transparent liquid at room temperature, with a special and irritating odor. Its melting point is quite low, about -70 ° C, which means that it can still maintain a liquid state in a low temperature environment. The boiling point is between 171 and 172 ° C, indicating that a higher temperature is required to boil it into a gaseous state.
Dimethylaminoacetonitrile has a lower density than water, about 0.88 g/cm ³, so if mixed with water, it will float on the water surface. Its solubility is special, and it can be miscible with common organic solvents such as ethanol and ether. This is because it is similar to the force between these organic solvent molecules and follows the principle of "similar miscibility"; however, its solubility in water is limited and only partially dissolved.
In addition, dimethylaminoacetonitrile has a low vapor pressure and relatively weak volatility. It will less quickly evaporate into the air at room temperature and pressure. Its refractive index is about 1.4200. When light passes through the substance, the direction of propagation will change according to this specific ratio. This property may be used for identification in optical correlation detection and analysis.
These physical properties are of great significance for its application in chemical production and other fields. The low melting point allows it to maintain good fluidity in some low-temperature operation processes, making it convenient for transportation and reaction operations. The specific boiling point determines the temperature conditions required during separation and purification. The miscibility with organic solvents provides an excellent choice of reaction medium for many organic synthesis reactions.

When storing and transporting dimethylaminoethanol, the following aspects should be paid attention to:
First, the storage environment is the key. This substance should be stored in a cool and well-ventilated place. If placed in a high temperature environment, it is easy to cause its volatilization to increase, and even cause danger due to excessive temperature. For example, do not place it in direct sunlight to prevent the temperature from increasing the internal pressure and burying safety hazards. At the same time, the humidity in the storage place should also be suitable. Too humid environment may react with the substance and affect its quality.
Second, the choice and sealing of containers must be cautious. Containers made of suitable materials should be used to hold dimethylaminoethanol, such as corrosion-resistant metal or special plastic containers. In addition, the container must have a good seal to prevent it from leaking. Once it leaks, it will not only cause material loss, but also pose a threat to the surrounding environment and personnel safety. For example, there have been cases where the substance leaked due to poor sealing of the container, corroded the peripheral equipment, and the volatile gas had an adverse effect on the health of the operator.
Third, the protection during transportation should not be underestimated. During transportation, the vehicle should be equipped with necessary fire fighting equipment and leakage emergency treatment equipment. During transportation, severe bumps and collisions should be avoided to prevent leakage caused by damage to the container. Moreover, the transportation vehicle needs to be kept away from fire and heat sources. In summer, it is recommended to choose the morning and evening periods for transportation to avoid high temperatures. For example, if it is transported during the high temperature in summer, if effective cooling measures are not taken, it may be dangerous due to the high temperature in the car.
Fourth, during storage and transportation, it should be strictly stored and transported separately from oxidants, acids and other substances. Because of its contact with these substances, chemical reactions are prone to occur, and even serious consequences such as combustion and explosion. For example, there have been cases where dimethylaminoethanol was mixed with oxidants, and the two were contacted due to unexpected circumstances, which caused violent reactions and caused significant losses.
In short, when storing and transporting dimethylaminoethanol, various factors need to be considered in all aspects, and relevant norms and requirements must be strictly followed, so as to ensure its safety and stability.
