What is the main use of 3-iodine-4-hydroxybenzaldehyde?
As recorded in "Tiangong Kaiwu", the main uses of the 3-4-based bud beetle are as follows:
The bud beetle of the base beetle has a warm and refreshing nature, and is quite useful in the medical way. Ancient healers often used it as medicine to treat various diseases. Gai because of its ability to disperse wind and cold, if a person is invaded by wind and cold, the body feels cold, fever, and no sweat. The beetle beetle is compatible with other medicines, and it can be taken in decoction to make the beetle open and vent, and the evil of wind and cold comes out with sweat, and the heat retreats.
And it is also beneficial to the spleen and stomach. If the spleen and stomach are weak, the transportation and transformation are abnormal, resulting in stagnation of diet and fullness of the abdomen, the basilica can help the spleen and stomach transportation and transformation, digestion and accumulation, and smooth the qi of the spleen and stomach. It can also be reversed in the middle. In case of nausea and vomiting, if used properly, it can stop vomiting and reverse, and restore the normal rise and fall of the spleen and stomach.
In the process of cooking, the basilica sprouts are also indispensable. Its spicy smell can break the fishy smell of the ingredients and increase the flavor of the dishes. For example, when cooking fish and meat, add a little to make the fishy smell dissipate, the aroma is overflowing, and the food feels more delicious.
Furthermore, in some filth and epidemic prevention measures, it can also be seen. Burn it in the room, or put it in a sachet and wear it on the body, which can prevent the invasion of the evil of the epidemic and ensure people's well-being.
What are the synthesis methods of 3-iodine-4-hydroxybenzaldehyde?
There are many synthesis methods of 3-drug-4-fluoryl aspirin, each with its own advantages. From the perspective of "Tiangong Kaiwu", it is described in ancient Chinese as follows:
First, salicylic acid is used as the base, through the method of acylation. First take an appropriate amount of salicylic acid, put it in a clean vessel, add an appropriate amount of acetic anhydride, and add a little concentrated sulfuric acid as the catalyst. Heat the fire slowly, stirring frequently in the meantime to make all things blend. Salicylic acid and acetic anhydride respond to heat, the hydroxyl group of salicylic acid is combined with the acyl group of acetic anhydride, and gradually water and acetylsalicylic acid. This is the embryonic form of aspirin. After the application is completed, it is quenched with ice water, crystallized out of the liquid, filtered and obtained, and then recrystallized in the alcohol liquid to make the quality pure. This way is simple, but the catalyst sulfuric acid is corrosive, so it needs to be handled with caution.
Second, it can be started with methyl o-hydroxybenzoate. First, it should be alkylated with the halogenated alkane with the help of an alkali agent, and a fluorine group should be introduced. The alkali used, such as potassium carbonate and sodium hydroxide, and the halogenated alkane is selected to contain fluorine. The temperature should be controlled and controlled at the right time, so that the fluorine group can be precisely connected. After hydrolysis, the acid or base is used as the catalyst to break the ester group to form an acid to obtain fluorosalicylic acid. The method of re-acylation, as mentioned above, reacts with acetic anhydride to form fluoro-aspirin. Although this method is complex, it has excellent control over the introduction of fluorine groups and good product purity.
Third, it also starts with phenols and goes through multiple steps. First, phenols and halocarboxylic acid esters are used to obtain esters, and then cyclization, fluorination, hydrolysis, acylation and other steps are carried out. This path of steps is complex, but it is convenient to modify the structure, and different fluoro-based aspirin variants can be made on demand.
All this synthesis method has advantages and disadvantages. In practice, when it is based on the ease of access to raw materials, cost considerations, and quality of products, it is necessary to choose carefully to achieve the best synthesis environment.
What are the physical properties of 3-iodine-4-hydroxybenzaldehyde?
3-4-Poria red bean barley material reason, with the following characteristics:
Poria, Poria is a polyporaceous fungus Poria dry sclerotia. Its shape is more or less spherical, shape or not, different sizes. The surface is light brown or dark brown, and the outer skin is thin and rough, with bright color.
Poria red bean, the mature seed of the leguminous plant red bean or adzuki bean. Shaped and slightly flattened, 5-8 mm, straight 3-5 mm. The surface is dark, slightly glossy, and there is a depression in the center of the barley surface, which is biased to one end. White, one-third of the total. Hard, not easy to break. The skin is thin, the child is 2, milky white. It is slightly sweet in taste, and it is chewy with bean fishy.
The barley is a mature kernel of the barley of the family of grasses. It is ovate or ovate-shaped, 4-8 mm, 3-6 mm. The surface is milky white, smooth, and occasionally brownish. One end is dark, and the other end is slightly concave, with a light brown. The back is convex, and the ventral surface has a deep skin. Hard, white on the surface, powdery. Small, sweet taste.
Each of the three has its own specific physical properties, and they have different effects in terms of use and consumption. They play an important role in various methods and diets.
What is the price range of 3-iodine-4-hydroxybenzaldehyde in the market?
Today, there are three to four million people who want to know the cost of Poria A in the market. The husband of Poria A has both the effect of reducing food and food, so it is affected by factors such as supply and demand in the product, the land, and the market.
If you use ordinary products to sell Poria A, you can buy it from the usual place, and the market supply is abundant, the cost per catty may be between 200 and 300. This Poria A, which is very special, can also meet the needs of ordinary people for daily consumption or use.
For those who are of high quality, or who are self-named and have access to the land, the land is better, and the effect is also better. Such Poria A, the cost per catty may rise to 500 to 800. Because of its excellent quality, it is often favored by wealthy families or those who pursue high-quality food, so the price is not cheap.
If the demand in the market is strong, and there is a shortage of supply, the price of ordinary or high-quality Poria A can be improved. The average person may break through 300, and the high-quality person may even exceed 800, or even a thousand.
However, if the supply is in demand, the price will definitely drop. The average Poria A can drop below 200, and the high-quality person can also guarantee 500, or fall to about 400. In other words, the city of Poria A is roughly the same, but the market is instantaneous, and the price still depends on the situation.
What are the storage conditions for 3-iodine-4-hydroxybenzaldehyde?
"Tiangong Kaiwu" reports that Poria cocos are transformed by the gas of pine roots, and their growth and preservation are all exquisite.
Poria cocos are formed, mostly in the land of deep mountains and old pine. Pine trees are old and old, and their roots are gradually rotting in the soil. Poria cocos are born around the rotten pine roots, and they are formed by the residual gas of pine roots. Therefore, after picking Poria cocos, if they are properly preserved, the first dry environment should be used. Because Poria cocos like dryness, humid places are prone to mildew and rot. If placed in a dark and humid place, plaque can be seen on its surface before ten days, and gradually turn into rot, losing their medicinal and other values.
To preserve Poria cocos, it needs to be dried first. Spread it out in the sun and turn it frequently to ensure that its whole body is dry and uniform. To a certain extent, the texture of the Poria cocos is solid and the moisture is exhausted. Then, choose a sealed container such as a pottery urn or porcelain jar, with a built-in lime package to absorb moisture, and then put the Poria cocos in and seal the mouth of the jar. In this way, the Poria cocos can be kept intact for a long time.
Furthermore, the storage place should be well ventilated. Although sealed and stored, it should not be placed in an occluded place. Good ventilation can circulate air and prevent moisture accumulation, which can further avoid mildew of the Poria cocos. If the ventilation is not smooth, even if it is dry at the beginning, it is also prone to moisture after a long time.
In addition, to avoid the harm of rodents and insects. Poria cocos have a The storage place should be tight to prevent rodents from biting and insects and ants from eating. It can be sprinkled with lime powder or realgar around the container where the Poria cocos are placed to repel rodents and insects. So many parties pay attention to it, so that the Poria cocos can be properly preserved without losing its effectiveness.
