The physical characteristics of triethylamine are as follows:
From the perspective of normal temperature and pressure, it is a colorless to light yellow transparent liquid with a strong ammonia odor and a pungent smell. It can evaporate in the air. Its boiling point is about 89.5 ° C and its melting point is -114.7 ° C. Such a melting boiling point makes it exist as a liquid in ordinary environments.
The density of triethylamine is smaller than that of water, about 0.726 g/cm ³, so if it is mixed with water, it will float on the water. And its solubility is also an important physical property. It can be soluble in organic solvents such as ethanol and ether, and it also has a certain solubility in water. This is because its molecular structure contains polar groups, which can form hydrogen bonds with water.
In addition, triethylamine is volatile, and its vapor is heavier than air, which can spread to a considerable distance at a low place, and may cause the risk of backfire in case of fire. And because it is a liquid, it has good fluidity. If it leaks inadvertently, it is easy to flow on the ground and expand the scope of pollution.
In addition, its refractive index is also a characteristic, about 1.399 (20 ° C). This physical constant can be used as one of the basis for identification in optical analysis and other fields. Overall, the various physical properties of triethylamine have a critical impact on the application of chemical, pharmaceutical, and other fields, depending on the way it is stored, transported, and used.

(Trimethyl) alkane, its chemical properties are special. This compound has a certain activity, and it often shows a specific surface in the reaction of polymers.
It contains special atoms, which makes its chemical properties different from those of ordinary alkanes. In the reaction of nuclear substitution, (trimethyl) alkanes can exhibit high inverse activity. Due to the methyl group in its body, it is affected by trimethyl groups, and the density distribution of its children is changed, making it easier for the nucleus to act and replace the atoms or groups on it.
In the reaction of oxidation, (trimethyl) alkanes also have special properties. Due to the existence of trimethyl groups, the environment of carbon in the molecule is changed, making its oxidation reaction different. Partial oxidation can oxidize the carbon in the vicinity of trimethyl groups to generate specific oxidation compounds.
And (trimethyl) alkane in the reaction of free radicals also has special measures. Due to its particularity, the reaction of free radicals to its reaction process is generally poor. Free radicals may first attack the carbon atoms of trimethyl groups, leading to a series of reactions that are different from normal ones.
And the chemical properties of (trimethyl) alkanes are also affected by external components. Factors such as degree of solubility and solubility can all affect its reaction rate and distribution of compounds, resulting in the influence of production. If the temperature is increased, the reaction rate can often be accelerated, but it may also cause the reaction to change. Different dissolution, due to the different properties, can also affect the reaction of (trimethylmethyl) alkane.

There are several methods for the synthesis of triethylamine.
One is the method of using ethanol and ammonia as raw materials. Introduce ethanol and ammonia in an appropriate ratio into a reactor filled with a specific catalyst. Raise the temperature to a suitable range and maintain a certain pressure. Under the action of a catalyst, ethanol and ammonia undergo a chemical reaction, and go through a series of complex intermediate steps to form triethylamine for life. During this reaction process, temperature, pressure and catalyst activity all have a great influence on the reaction rate and product yield. If the temperature is too high or too low, it may cause more side reactions and lower yields.
The second is the synthesis path using acetaldehyde and ammonia as the starting materials. First, acetaldehyde and ammonia are condensed under specific conditions to form an intermediate product. Then, the intermediate product is further reacted into triethylamine under suitable catalysts and reaction conditions. In this method, precise control of reaction conditions is crucial. Factors such as the pH of the reaction and the reaction time all affect the process of the reaction and the purity of the final product.
In addition, there are also synthesis methods using halogenated ethane and ammonia as raw materials. Halogenated ethane and ammonia in a suitable solvent undergo nucleophilic substitution in the presence of a base. The halogen atom is replaced by the nitrogen atom in ammonia, and triethylamine is gradually formed. However, it is necessary to pay attention to the selectivity of the reaction in this process, because other side reactions of halogenated ethane may occur, forming impurities, which affects the purity of triethylamine. To obtain high-purity products, the reaction conditions need to be carefully regulated, and the products need to be properly separated and purified.
All synthesis methods have advantages and disadvantages. In practical applications, it is necessary to comprehensively consider the availability of raw materials, cost, product purity requirements and many other factors, and carefully select the appropriate synthesis method.

When storing and transporting methyl products, many matters need to be taken into account.
When storing, the environment is the most important. The place where it is located should be dry and well ventilated, away from fire and heat sources. If it is in a humid place, it is easy to cause its properties to change and affect the quality; if it is close to fire or heat, it may be dangerous or cause ignition and explosion. And it needs to be stored separately from other things to avoid interaction and accidents.
Furthermore, the choice of container is also critical. It is necessary to use a suitable device, which can close together and prevent leakage. The material should be resistant to corrosion to ensure its stability.
As for transportation, speed and stability cannot be ignored. The speed should not be fast, to prevent damage to its quality or leakage due to vibration and collision. The transportation vehicle should be fully equipped and equipped with emergency equipment in case of accidents.
The escort must be clear about its nature and know the emergency method. Check often on the way to see if there are any leaks or abnormal signs. In case of bad weather such as wind and rain, you should be more cautious and find a suitable place to temporarily avoid to ensure safety.
In this way, when storing and transporting methyl in Sanxiang, pay attention to everything carefully, so as to be safe and avoid disasters.
