In the chemical industry, it is often used as a solvent. Because of its good solubility, it can dissolve many organic compounds, such as resins, rubbers, etc. When preparing specific substances in chemical production, triethylamine can be used as a solvent to make the reaction more uniform and efficient, and promote the full contact of the reactants to achieve better reaction results.
is also an important raw material and reagent for organic synthesis. In many organic synthesis reactions, such as acylation reactions and alkylation reactions, triethylamine can be used as a base catalyst. It can capture the acid generated by the reaction, move the reaction equilibrium to the product direction, and improve the product yield. In the pharmaceutical industry, triethylamine often plays a key role in the synthesis of many drug molecules, assisting in the construction of complex drug structures.
In the rubber industry, it can be used as a vulcanization accelerator. It can accelerate the vulcanization process of rubber, improve the efficiency and quality of rubber vulcanization, and make rubber products obtain better physical and mechanical properties, such as hardness, strength, etc., making rubber products more durable.

What are the physical properties of triethylamine?
The three ointments have all kinds of physical properties. Its color may be crystal clear, if the agar pulp initially coagulates, the color is warm and transparent, and it is pleasing to the eye. The texture is delicate, smooth but not greasy, just like condensation, and the fingertips are brushed, just like caressing the clouds, giving people a soft feeling.
Smell its smell, fragrant and rich, mellow as herbs, and also contains a little quiet fragrance. The two blend, the aroma is lingering, refreshing, and the smell is refreshing. As for its texture, at room temperature, it is semi-solidified, like a paste like fat, with both flexibility and plasticity. If you twist it with your fingers, the paste can be extended and continuous, as if it has life, and can change its shape with external forces. When
is heated, the three remaining ointments gradually melt, just like spring snow when it is warm, slowly turning into a liquid state, with good fluidity, and can be evenly spread on the surface of the utensils. After cooling, it returns to a semi-solidified state, which makes it relatively stable under different environmental conditions, making it easy to store and use. Its viscosity is moderate, and it can not only fit closely with other things, but also not too sticky and difficult to clean. It is actually a wonderful thing with a variety of excellent physical properties.
What are the chemical properties of triethylamine?
Triethylamine is also an organic compound, and its properties are quite specific. Let me describe it in detail for you.
The shape of triethylamine is a colorless liquid under normal circumstances, and it smells strongly of ammonia, just like the smell of rotten fish. This smell is pungent and easy to detect. Its boiling point is about 87.2 degrees, and its melting point is negative 113.2 degrees. As a result, it is liquid at room temperature and pressure, and has a certain volatility, which can gradually evaporate in the air.
As for solubility, triethylamine can be miscible with various organic solvents such as ethanol and ether, but its solubility in water is limited. Due to its molecular structure, the hydrocarbyl group is partially lipophilic, while the amino group can form hydrogen bonds with water, but the hydrocarbyl group has a great influence, so it is only slightly soluble in water.
Triethylamine is chemically active and is a typical organic base. Its nitrogen atom has a pair of lone pair electrons, so it is alkaline and can neutralize with acids to generate corresponding salts. If it interacts with hydrochloric acid, it generates triethylamine hydrochloride, which is a rapid and complete reaction. At the same time, triethylamine is also often used as an acid binding agent in organic synthesis, which can combine with the acid generated by the reaction and promote the forward reaction.
Furthermore, triethylamine can participate in many nucleophilic substitution reactions. Due to the nucleophilicity of the solitary pair electron of the nitrogen atom, it can attack the electron center of the electrophilic reagent, so as to realize the construction and transformation of the molecule. For example, in the nucleophilic substitution reaction of halogenated hydrocarbons, triethylamine can assist the nucleophilic reagent to play a better role, improve the reaction efficiency and selectivity.
The stability of triethylamine is acceptable under normal conditions, but it is flammable in case of open flame and hot topic. Its vapor and air can form an explosive mixture. In case of open flame and high heat, it can cause combustion and explosion. Therefore, when storing and using, it is necessary to strictly follow safety procedures and keep away from fire and heat sources to prevent unexpected disasters.
What are the precautions for triethylamine during storage and transportation?
Those who are more than three years old, in the process of hiding, pay attention to things like this, and need to be careful.
The first word to hide, one is that you must be careful. It should be placed in a dry, dark and transparent corner to avoid direct exposure to light, because the sun is strong, or the resistance is easy. If the product is easy to deliquescence, especially to prevent it, you can use lime and other materials to absorb moisture and keep it dry. Second, the degree should also be different. Different degrees of resistance are required. Where it is hot, it is generally perishable and easy to be damaged, and it should be placed in an ice cellar or a low place to prevent it from being damaged; in case of cold, some products should also be properly held to prevent it from being damaged. Third, divide them and do not mix them. Toxic substances, such as those that are prone to odor, also need to be separated and stored to ensure that their respective characteristics are correct.
Second, first, the packaging should be fixed. Properly wrap in thick materials, wooden boxes, etc., and fill in materials such as cotton wool and straw, to prevent the product from being damaged due to the collision of earthquakes. Second, pay attention to the speed of the car. The food used in an emergency should arrive as soon as possible, and should not be delayed, so as not to save the patient from the treatment. Third, those who need it must be careful. Knowing the nature of the product, the method of holding it, take care of it on the way, and in case of any situation, and place it safely, so that the product can arrive safely.
In this case, the three-year-old warehouse has been hidden and treated with the heart and the method of refinement, so as to ensure the best effect of the product and the disease of the world.
What are the hazards of triethylamine to human health?
The three-wart swimming crab has a salty taste and a cold nature. Eating too much does have various obstacles to human health.
"Compendium of Materia Medica" says: "Crabs are fierce in nature and can septic blood." The three-wart swimming crab is not only a crab, but also cold in nature. The human spleen and stomach like warmth but hate cold. If you eat more swimming crab three warts, the cold and cool qi can easily hurt the spleen and stomach yang qi, resulting in abnormal transportation and transformation of the spleen and stomach. Those with the spleen and stomach are the source of qi and blood biochemistry. If the spleen and stomach are damaged, the qi and blood biochemistry will be insufficient, showing loss of appetite, bloating and abdominal pain, diarrhea and loose stools.
Because the three-wart swimming crab is a high-protein food, eating too much can easily increase the burden on the stomach and intestines. The gastrointestinal transportation and transformation are not enough, and the food accumulates in it, which can produce damp heat. Damp and heat accumulate, or develop diseases such as itchy skin and eczema.
And the three warts swimming crab mostly feeds on water rot, and the body may contain parasites, bacteria and other harmful substances. If it is not cooked properly and cannot be completely killed, after human consumption, parasites, bacteria, etc. are easy to invade the human body, causing abdominal pain, diarrhea, nausea, vomiting and other gastrointestinal diseases, and even more serious infections.
In addition, its cold nature is easy to cause qi and blood clotting. For women, especially those during menstruation and pregnancy, eating too much can easily cause cold coagulation and blood stasis, cause poor menstrual blood, dysmenorrhea, and even affect the stability of the fetus, endangering the fetus.
Therefore, although Portunus trituberculatus tastes delicious, when eating it, it should be controlled and cooked properly, so as not to damage human health.
