2-% hydroxytriethylamine is an organic compound, which is widely used in various fields such as chemical industry. Although "Tiangong Kaiwu" does not directly describe this substance, it is deduced from the ancient chemical process and material application ideas, and its related uses can be known.

In chemical synthesis, it is often used as an intermediate. Gaiyin 2-% hydroxytriethylamine has a special chemical structure and can participate in a variety of chemical reactions. If it reacts with acids, it can form esters, which are very useful in flavors, coatings and other industries. Although ancient chemical processes were not as precise and complicated as they are today, they had long known the laws of material reactions, such as alchemy and brewing. It is clear that substances can interact to produce new substances. Nowadays, the synthesis of 2-% hydroxytriethylamine as an intermediate follows this principle. By virtue of its structural characteristics, the desired product is prepared by a specific reaction.

In the preparation of surfactants, 2-% hydroxytriethylamine is also an important position. It can react with fatty acids to prepare surfactants. Surfactants can reduce the surface tension of liquids and are crucial in washing and emulsifying processes. In ancient times, washing with plant ash, saponin, etc. was a way to reduce surface tension by using natural materials. Today, using 2-% hydroxytriethylamine to make surfactants is an advanced technology, and its chemical properties are used to optimize washing and emulsifying effects.

What are the physical properties of 2-aminotrifluorotoluene?

2-% hydroxytrifluorotoluene, its physical state is mostly liquid at room temperature, colorless and transparent and has a special odor. Looking at its shape, the pure one is clear and clear, like a clear spring. Its boiling point is about 107-108 ° C. Due to the introduction of fluorine atoms, this boiling point is different from that of general toluene derivatives. Fluorine atoms have high electronegativity, which has an impact on intermolecular forces. The melting point is about -27 ° C, and it can solidify into a solid state at low temperatures.

When it comes to solubility, it is easily soluble in organic solvents, such as ethanol, ether, acetone, etc., and can interact with these organic solvent molecules by Van der Waals forces, etc., and dissolve harmoniously. However, in water, due to its molecular structure containing hydrophobic toluene and fluorinated groups, it is insoluble and has weak interaction with water molecules, making it difficult for the hydrogen bond network between water molecules to accept this molecule.

Its density is greater than that of water, about 1.247g/cm ³. If it is placed in a container with water, it will sink to the bottom of the water and be well-layered. Its vapor density is also greater than that of air. If it leaks into the air, the vapor tends to spread close to the ground and accumulate in low-lying places.

2 -% hydroxytrifluorotoluene has a specific refractive index. When light passes through, it will be refracted at a specific angle due to the molecular structure and electron cloud distribution. This characteristic can be used for purity detection. And its chemical stability is high, fluorine atoms regulate the distribution of electron clouds in the benzene ring, change the activity of the benzene ring, and enhance the resistance to some chemical reactions. However, under specific conditions, such as suitable catalysts, temperatures, and pressures, hydroxyl groups can participate in esterification, substitution, and other reactions, showing unique chemical activities.

What are the chemical properties of 2-aminotrifluorotoluene?

2-% hydroxytrifluoroacetic acid, this material property is unique. Its color is usually colorless and transparent, in a liquid state, and it exists stably at room temperature and pressure.

Looking at its melting point, the melting point is quite low, so it is difficult to solidify in normal cold and warm. The boiling point is also not very high, and it is easy to vaporize into steam when heated a little. This property makes it easy to operate and use in a liquid state.

When it comes to solubility, it has good solubility in water and various organic solvents. It is insoluble with water and easily soluble in organic solvents such as alcohols and ethers. This good solubility, in the field of chemical synthesis, can be used as a solvent to help the reactants blend and promote the rapid reaction.

In addition to its acidity, 2-% hydroxytrifluoroacetic acid is strongly acidic. Because of its molecular structure, fluorine atoms are very electronegative, and their electron-absorbing effect is significant. The hydrogen atoms in the hydroxyl group are easily dissociated and protons are released, so the acidity is quite strong. This strong acidity is used in organic synthesis and can be used as a catalyst to promote many organic reactions, such as esterification and hydrolysis, changing the rate and path of chemical reactions.

As for chemical stability, although it is still stable at room temperature and pressure, it is also dangerous to encounter hot topics, open flames or strong oxidants. At high temperatures, it may cause decomposition and produce harmful hydrogen fluoride gas. When it encounters strong oxidants, it may react violently, causing the risk of explosion. Therefore, when storing and using, we must follow safety procedures and be cautious.

2-% hydroxytrifluoroacetic acid has important uses in organic synthesis, medical chemistry and other fields due to its unique physical properties. When it is used, it should not ignore its latent risk and should be properly handled.

What is the production method of 2-aminotrifluorotoluene?

2-% hydroxypropionic acid, or lactic acid, is an intermediate product of sugar metabolism in the human body and is widely found in nature. Although the production method of 2-hydroxypropionic acid is not directly described in "Tiangong Kaiwu", the following methods can be deduced based on ancient brewing and fermentation processes:

###1. Selection of raw materials
Use carbohydrate-rich grains, such as rice, wheat, corn, etc., or carbohydrates, such as sucrose, glucose, etc. as starting materials. Because microbial fermentation requires sugars as substrates to produce lactic acid.

####II. Pre-fermentation treatment
1. ** Grain treatment **: If using grain, first wash and soak it to make the grain fully absorb water and expand. Then cook it to make the starch gelatinized, which is easier for subsequent microbial enzymatic hydrolysis. For example, when soaking rice for several times, steam it until cooked.
2. ** Sugar dissolution **: If using sugar, dissolve it directly in an appropriate amount of water to prepare a certain concentration of sugar liquid to provide a suitable nutrient environment for fermenting microorganisms.

###III. Fermentation process
1. ** Microbial inoculation **: Although there was no modern purebred culture technology in ancient times, raw materials rich in lactic acid bacteria in the natural environment, such as old brine in kimchi jars, or fermented dairy products, can be used to access the treated raw materials. Lactic acid bacteria will convert sugars into lactic acid.
2. ** Fermentation conditions control **:
- ** Temperature **: Maintain in the suitable growth temperature range of lactic acid bacteria, about 30-40 ° C. By placing the fermentation container in a warm place, such as next to the kitchen stove, or keeping warm in a wrapped container such as a straw mat in winter.
- ** Anaerobic environment **: Lactic acid bacteria are mostly anaerobic bacteria, so it is necessary to create anaerobic conditions. The method of sealing the fermentation vessel can be used, such as sealing the jar with mud to reduce the entry of oxygen and promote the anaerobic respiration of lactic acid bacteria to produce lactic acid. During the fermentation process, microbial metabolism will gradually increase the acidity of the material and increase the content of lactic acid.

###4. Separation and Purification
1. ** Preliminary Separation **: After the fermentation is completed, the fermentation broth contains lactic acid and other impurities. First, through filtration, solid impurities are removed with filter materials such as gauze to obtain a clarified fermentation broth.
2. ** Purification **: In ancient times, or by evaporation and concentration, the fermentation broth was heated and evaporated, so that the water gradually lost and the lactic acid concentration increased. As the water evaporated, the solubility of impurities changed, and some impurities It is also possible to use a simple extraction method to use some natural organic solvents, such as vegetable oils, to initially extract and separate lactic acid to improve the purity of lactic acid.

What should be paid attention to when storing and transporting 2-aminotrifluorotoluene?

When storing and transporting 2-% hydroxytrifluoroacetic acid, pay attention to the following matters:
First, when storing, find a cool, dry and well-ventilated place. This is because 2-% hydroxytrifluoroacetic acid is more active in nature, high temperature and humid environment can easily cause chemical reactions and damage its quality. And it should be kept away from fire and heat sources to prevent the hidden danger of open flames, because it encounters open flames or hot topics, or there is a risk of combustion and explosion.
Second, the choice of storage container is crucial. Corrosion-resistant materials, such as specific plastic or glass containers, are required. Genetically 2 -% hydroxytrifluoroacetic acid is corrosive, and ordinary materials are easy to be eroded, causing the risk of leakage and endangering the safety of the surroundings. The container must be tightly sealed to prevent it from evaporating, and to avoid contact with air, moisture and deterioration.
Third, when transporting, be sure to follow relevant regulations and standards. Make sure that the transportation vehicle is equipped with corresponding fire and leak emergency treatment equipment. If there is an accident such as leakage on the way, it can be properly disposed of in time. The loading and unloading process must be handled with care, and must not be handled brutally to prevent damage to the container.
Fourth, whether it is stored or transported, it should be separated from oxidants, alkalis and other substances, because it is easy to react with these substances and cause danger. And the storage area and transportation vehicles should be set up with clear warning signs to make everyone aware of the danger and treat it with caution.
Fifth, professional training is required for storage and transportation personnel to familiarize them with the characteristics, dangers and emergency treatment methods of 2-% hydroxytrifluoroacetic acid. In this way, in the face of emergencies, they can respond calmly and minimize harm.
