What are the main uses of 2,2,3,3,3-pentafluoropropanol?
The main use of Wushi powder was a very popular drug among scholars during the Wei and Jin Dynasties. When this medicine was taken, you might feel hot and irritable at first, but it had many "wonderful" effects after taking it for a long time, and it was widely used in society at that time.
One is to maintain good health. At that time, people believed that Wushi powder has the power of health preservation, and it can be used to strengthen the body, as if it can prolong life. Although from today's scientific point of view, this view is wrong, but in ancient times there was no scientific health awareness, and Wushi powder became a "good recipe" for health.
Second, it is a medium for social interaction. In the Wei and Jin Scholastics, serving powder is a fashionable move. When scholars get together, they often talk about whether to serve the powder or not, and the feeling of serving the powder. If a person is good at serving the powder and can describe its subtlety, he will easily gain the attention and recognition of everyone and integrate into the upper social circle. This style prevails, and Wushi powder has become an indispensable thing in the social field.
Third, use the medicinal power to pursue the spiritual realm. After taking the powder, the medicinal power occurs, and people may experience hallucinations and high spirits, as if they were in a different spiritual world. Some scholars use this to seek to transcend the world and comprehend the realm of metaphysics, which is in line with the prevailing metaphysical trend of thought at that time, and to use the medicinal power to help them achieve an otherworldly state at the spiritual level.
However, Wushi powder is quite toxic, and long-term use can easily cause physical weakness, disease, and even life-threatening. Although it was popular for a while, it was ultimately very harmful, and it was gradually not used by people in later generations.
What are the physical properties of 2,2,3,3,3-pentafluoropropanol?
The physical properties of Wuhe trienovaleraldehyde are as follows:
Looking at its color, at room temperature, the pure Wuhe trienovaleraldehyde is colorless and transparent, just like morning dew, with no impurities mixed in it.
Smell its taste, emit a unique fragrance, the aroma is rich and has a special charm, and the smell is comparable to that of ordinary people. It is like being placed in a blooming flower, but its taste is also irritating. If it is smelled for too long, it may cause nasal discomfort.
In terms of its state, when it is at room temperature and pressure, it is a flowing liquid, just like smart water, which can flow freely, with uniform texture and no sticky feeling.
Measure its melting and boiling point, the melting point is quite low, about minus several degrees, it is difficult to see it condensing into a solid state at room temperature; the boiling point is relatively high, and it can boil into a gaseous state within a specific temperature range. This characteristic allows it to exist in different forms under different temperature environments.
Measure its density, which is slightly lighter than water. If it is placed in the same place as water, it can be seen that it floats on the water surface, and the two are clearly defined.
Looking at its solubility, it shows good solubility in organic solvents, such as ethanol, ether, etc., and can be fused with it; however, in water, the solubility is limited, and it can only be dissolved a little, just like the state of oil and water, which is difficult to integrate. The volatility of Wuhe Trienylvaleraldehyde cannot be ignored either. In the air, its molecules are easy to escape, causing its odor to spread rapidly. Therefore, it needs to be properly sealed during storage to prevent evaporation.
What are the chemical properties of 2,2,3,3,3-pentafluoropropanol?
The chemical formula of pentaborane is $B_5H_9 $, which is an inorganic compound. Its chemical properties are specific and worthy of detailed investigation.
pentaborane has a high degree of reactivity. It is highly prone to spontaneous combustion in the air, and can cause intense combustion when exposed to open flames or hot topics. Due to the distribution of chemical bond energy between boron and hydrogen in pentaborane, it is prone to oxidation in the presence of oxygen, releasing a large amount of heat and light quickly, just like dry wood and fire, which cannot be stopped.
And pentaborane can also react significantly with water. The properties of boron make it easy to interact with water molecules, hydrolyzing to produce boric acid and hydrogen. This reaction process is like a microscopic chemical "drama", where molecules interact, old bonds break, and new bonds are formed, thus changing the form and properties of substances.
Furthermore, pentaborane can be used as a high-energy fuel. Its combustion heat is very high, and it contains huge chemical energy. Under specific conditions, it can release far more energy than ordinary fuels, so it may have potential application value in some special energy demand scenarios, such as the aerospace field. However, due to its lively chemical properties, extreme caution is required when storing and using, and various safety hazards are prevented. Just like controlling a hot horse, it requires superb skills and strict protection. In short, the chemical properties of pentaborane are active, combustion, hydrolysis and other characteristics, so that it has a unique position in chemical research and specific application fields.
What are the precautions for using 2,2,3,3,3-pentafluoropropanol?
For those who use Wushi San, when taking it, there are many taboos to avoid, which should be kept in mind.
First, after taking the medicine, you need to use the powder. This is the key move, you need to walk slowly, so that the power of the medicine can be dispersed, and you can't sit and lie for a long time and make the power of the medicine stagnant. If you don't use the powder, the power of the medicine will accumulate in the body, and you may have all kinds of discomfort.
Second, you should also pay attention to your diet. It is advisable to eat cold things, because Wushi San is hot and dry, and eating cold can slightly slow down its hot and dry trend. However, you should not eat raw and cold, which will damage the spleen and stomach. Food such as cold food can be eaten in moderation. Hot food should be avoided, so as not to help it get hot
Third, the clothes should not be too thick. The powder heats up, and the thick clothes cover it. The heat cannot be dissipated, which is easy to cause boredom and even change. It is advisable to wear light and breathable clothes, so that the hot air is easy to dissipate.
Fourth, during the medication, the mood needs to be adjusted. Do not be angry, do not worry, and maintain a peaceful state of mind. If the emotion is too intense, the qi and blood are reversed, and it interacts with the medicinal force, it is possible to be unpredictable.
Fifth, be cautious about the dosage of the medicine. It is advisable to try a small dose at the beginning, observe the reaction of the body, and then consider increasing or decreasing it. Do not take a large amount rashly, so as not to take the medicine too violently and damage the viscera.
Furthermore, during the course of taking the medicine, if there are any abnormalities in the body, such as excessive fever, vomiting and diarrhea, trance, etc., stop taking it immediately and seek medical advice without delay.
All these are the precautions when taking Wushisan, which need to be followed carefully to ensure the safety of the medication.
What are the production methods of 2,2,3,3,3-pentafluoropropanol?
The method of making five-sorghum liquid is simple, as described below.
First, the raw materials are required. It is necessary to use sorghum, rice, glutinous rice, small rice, and corn as the basis of the five-layer material. For sorghum, the wine is made of bones to make it mellow; for rice, it is clear and soft to increase the wine; glutinous rice makes the wine dense and the taste is plump; for small-scale fragrance, the wine is added to the wine; for corn is sweet, making the wine taste more delicious. The proportion is exquisite, and the foundation of the special taste of the five-sorghum liquid is obtained.
Second, there is something wonderful about making music. With small-scale and small-scale master, with a lot of exquisite craftsmanship. First, the small-scale broken, plus the amount of water, step to make a curved billet. Place it in the koji room and control it according to the order. The first time it rises, the microorganisms multiply, and then decline, so that the fragrance of the koji can be nurtured and settled. The made koji is fragrant and depressing, rich in microorganisms and enzymes, and leavening energy.
Third, the process of leavening is studied. In the old cellar pond, the well-prepared grains and grains are mixed in proportion, using the method of "mixed ingredients, mixed steaming and mixing". The old cellar mud is rich in microorganisms, and it has been used for many years, and the wine is especially fragrant. The leavening cycle is here. The powder and microorganisms react to dissolve the aroma of alcohol, and the fermented grains can be matured for many months.
Fourth, the wine needs to be refined by steaming. The mature fermented grains are steamed with retort, and the wine steam is cold to make wine. Pinch the tail and take the essence. The wine contains a lot of wine, the alcohol content is low and the taste is low. The middle wine is the best, the aroma is mellow, and the taste is low.
Fifth, the hook is also important. The new wine needs to be placed in the pottery, so that the pests in the wine are low, the molecules are rearranged, and the taste is softer. The hook is mixed with the wines of different years and times, and the big and wonderful hand, and the five-beam liquid has a good taste, fragrant and sweet.
