4 - (ethylaminomethyl) pyridine, its physical properties are as follows:
This substance is mostly liquid at room temperature, and it has a colorless to light yellow appearance, clear and less impurities. Its odor is specific, slightly pungent, and detectable by smell.
When it comes to the boiling point, it is about 195-198 ° C. At this temperature, the liquid phase begins to turn to the gas phase, and the molecular movement intensifies, breaking free from the liquid phase. The characteristics of the boiling point can be obtained by distillation when separating and purifying.
In terms of melting point, it is roughly about -45 ° C. When the temperature drops, the thermal motion of the molecules slows down, changing from a disordered liquid state to an ordered solid state, and the arrangement tends to be regular. Melting point data can be quite guiding when identifying substances and controlling crystallization conditions.
The density is about 0.93-0.95g/cm ³, which is slightly lighter than water. If it is co-located with water, it can float on the water surface. This density characteristic is a key consideration in matters such as separation of mixed systems and material measurement.
In terms of solubility, it can be miscible with many organic solvents, such as ethanol and ether. Due to the similarity of molecular structure to organic solvents, it follows the principle of similar compatibility. In addition, the vapor pressure of 4 - (ethylaminomethyl) pyridine has a corresponding value at a specific temperature, which affects its volatilization rate. The vapor density is heavier than that of air, and in poorly ventilated places, steam easily accumulates near the ground. All kinds of physical properties are indispensable information in many fields such as chemical production, drug synthesis, and analysis and testing, guiding the direction of operation and research.

4 - (ethylaminomethyl) pyridine, this is an organic compound. Its physical properties, at room temperature or in a liquid state, have a specific odor, have a certain solubility in organic solvents, because it contains nitrogen atoms, or is weakly basic.
Looking at its chemical properties, because it contains a pyridine ring and an ethylaminomethyl side chain, the pyridine ring is aromatic and can undergo electrophilic substitution reactions, such as halogenation, nitrification, sulfonation, etc. The substitution check point is mostly at the higher electron cloud density of the pyridine ring. In the ethylaminomethyl side chain, the nitrogen atom has lone pairs of electrons, which can be used as nucleophilic reagents to participate in the reaction, such as nucleophilic substitution with halogenated hydrocarb And the hydrogen on the nitrogen atom in the compound can participate in the acid-base reaction and react with strong acids to form salts.
Furthermore, the carbon-nitrogen bond and carbon-carbon bond of the side chain can be broken and reacted under appropriate conditions, or converted into oxidation and reduction. Because the structure contains carbon, hydrogen, and nitrogen elements, carbon dioxide, water, and nitrogen oxides will be formed when burned. In short, the chemical properties of 4- (ethylaminomethyl) pyridine are determined by its structure, and it may have many applications in organic synthesis, pharmaceutical chemistry, and other fields.

To prepare 4 - (ethylaminomethyl) pyridine, it is often done by number method.
First, pyridine formaldehyde and ethylamine are used as the starting materials to carry out the method of reducing amination. With the help of appropriate temperature and catalyst, the two first become imine intermediates, followed by hydrogen sources such as sodium borohydride or hydrogen, catalytic hydrogenation, and reduction of imines to obtain the target product 4- (ethylaminomethyl) pyridine. This way the raw material is easy to cause, the reaction is relatively easy, and the yield can be observed.
Second, it can be obtained by the nucleophilic substitution of 4-halomethyl pyridine and ethylamine. The halogen atom of halomethylpyridine is quite active, and the nitrogen atom of ethylamine is nucleophilic. When the two meet, the halogen atom is replaced by ethylamino group to give rise to 4- (ethylaminomethyl) pyridine. However, it is necessary to pay attention to the control of reaction conditions to avoid side reactions, such as the formation of polysubstituted products.
Third, with pyridine as a group, first introduce suitable functional groups, and then undergo a series of conversions. For example, under specific reagents and conditions, pyridine can be directly obtained by Mannich reaction with paraformaldehyde and ethylamine. This reaction can build the desired structure in one step, but it requires more severe reaction conditions, and the selection and ratio of reagents are also heavy.
All synthetic methods have their own advantages and disadvantages. In practice, the most suitable method should be selected according to the availability of raw materials, cost, yield and product purity, so as to achieve the purpose of efficient preparation of 4- (ethylaminomethyl) pyridine.

For 4 - (ethylaminomethyl) pyridine, there are several ends that should be paid attention to when using it. The first safety protection, this substance may be irritating, contact the skin, eyes, fear discomfort, and even damage. Therefore, when handling, be sure to wear protective clothing, goggles, and gloves to prevent accidental contamination. If you touch it, rinse it with plenty of water as soon as possible, and seek medical attention if necessary.
times are related to storage. It needs to be placed in a cool, dry and well-ventilated place, away from fire and heat sources to prevent fire or deterioration. At the same time, it should be stored separately from oxidants and acids to avoid dangerous chemical reactions caused by mixed storage.
Furthermore, during use, it is crucial to accurately control the dosage. Because in different reactions and applications, the required dosage varies greatly, the dosage is improper, or the reaction effect is not good, or other unexpected situations are caused.
In addition, the ventilation of the operating environment should not be ignored. Ensuring smooth ventilation in the working area can effectively reduce the concentration of this substance in the air and reduce the risk of inhalation.
Repeat, knowing its chemical properties is extremely important in use. Only by clarifying its reaction law with other substances can we avoid dangerous reactions during collocation and operation, and ensure the safety and efficiency of the process. In short, the use of 4- (ethylaminomethyl) pyridine requires careful treatment in all aspects and must not be negligent.
