3-iodo-2-hydroxybenzaldehyde

Alumite is the spirit of creation in heaven and earth, and its chemical properties are particularly unique. Among alum, green alum, potassium alum, etc. are common genera.
Green alum, the main component is ferrous sulfate heptahydrate (FeSO · 7H ² O). Its color is emerald green, placed in the air, and gradually changes the color of rust. Its ferrous ions (Fe ² 🥰) are highly reducible, and are easily oxidized by oxygen in the air and converted into trivalent iron ions (Fe ³ 🥰). During this process, the crystal structure of green alum also changes, losing its crystalline water and gradually becoming a yellow rust-like substance. And green alum is soluble in water, and its aqueous solution is weakly acidic. Due to the hydrolysis of ferrous ions, ferrous hydroxide and hydrogen ions are formed, so it is acidic.
Potassium alum, often refers to potassium aluminum sulfate dodecahydrate (KAl (SO) ³ · 12H 2O O). Its crystals are colorless, transparent and stable. It can be completely ionized in water to produce potassium ions (K ²), aluminum ions (Al ³) and sulfate ions (SO ²). Aluminum ions also hydrolyze in water to form aluminum hydroxide colloids. This colloid has adsorption properties and can absorb impurities suspended in water to clarify water, so potassium alum is often used as a water purification agent.
Alumite is often decomposed when heated. For example, when green alum is heated, it first loses crystalline water, and then further decomposes to produce gases such as sulfur dioxide and sulfur trioxide. When potassium alum is heated, it also loses crystalline water, but its structure is relatively stable and requires a higher temperature for further chemical changes.
All these are the chemical properties of alum. It is useful in many aspects of medicine, industry, and life. It is a wonder given by heaven and earth.

The genus of Fuling Baizhu powder is also used in the common combined method of Fuling Baizhu powder. Poria is sweet, light, flat in nature, and returns to the heart, lungs, spleen, and kidney meridians, which has the effect of promoting water seepage, strengthening the spleen, and calming the heart. Baizhu, bitter in taste, sweet in nature, warm in nature, returns to the spleen and stomach meridians, can strengthen the spleen and qi, dry and wet and water, stop sweating, and calm the fetus. The two are combined to strengthen the spleen and remove dampness.
Alisma, sweet in taste, cold in nature, returns to the kidney and bladder meridians, which can facilitate water seepage and dampness, and relieve heat. In the combined system, it can help benefit water with Poria, and prevent the warmth and dryness of Baizhu from being too much.
There is also licorice, sweet taste, flat nature, return to the heart, lungs, spleen, stomach meridian, with the ability to nourish the spleen and qi, moisten the lungs and relieve cough, clear heat and detoxify, and reconcile various medicines. In Fuling Baizhu Powder, it can be adjusted to reconcile various medicines, so that the effect of the whole prescription is more peaceful.
Furthermore, yam is often accompanied. Yam has sweet taste, flat nature, return to the spleen, lungs, and kidney meridians, can nourish the spleen and nourish the stomach, generate fluid and benefit the lungs, and nourish the kidney and Shibuin. Add to the prescription, help Baizhu enhance the power of strengthening the spleen, and nourish the lungs and
In addition, there are sand kernels, which taste refreshing, warm in nature, return to the spleen, stomach, and kidney meridians, and can be used to harmonize qi, warm the spleen and stop diarrhea, and calm the fetus. It can be used to replenish but not stagnate, and smooth the qi machine of Zhongjiao.
The combination of various medicines, either in powder or in decoction, is adjusted according to the severity of the disease and the reality of the person. To strengthen the spleen and seep dampness is the key, so that Zhongjiao is healthy, the water and dampness are reduced, and all diseases are relieved. It is actually a good recipe for reconciling the spleen and stomach and removing dampness.

In "Tiangong Kaiwu", it is written that kaosan, that is, Houttuynia cordata, is widely used and can play an effect in many fields.
In the field of medicine, its cold nature has the functions of clearing away heat and detoxifying, eliminating carbuncle and purulent discharge, and diuretic and leaching. In case of carbuncle and purulent vomiting, this grass can be used. Cover the disease of carbuncle, which is the accumulation of heat poison in the lungs, causing qi and blood to coagulate, resulting in carbuncle, Houttuynia cordata can clear the heat poison of the lung meridian, dissipate carbuncle, and promote the discharge of purulent sputum. Another example is hot, astringent and painful, due to the accumulation of damp heat under the coke, the bladder gasifies and loses its function. Houttuynia cordata can
In the field of diet, its young leaves can be eaten as vegetables. In Southwest and other places, it is often mixed with chili peppers, prickly ash, garlic, vinegar and other seasonings to form a cold dish with a unique flavor. It is refreshing and appetizing and enhances appetite. Although its unique smell is strange, it is also loved by many people.
In the ecological field, Houttuynia cordata has tenacious vitality and good adaptability to the environment. It can grow in wetlands, streams and other humid areas. Its root system is developed, which can stabilize the soil and prevent soil erosion. And in the ecosystem, it can provide habitat and food source for some insects and microorganisms, and also contribute to maintaining ecological balance.
In short, Houttuynia cordata has its own uses in medicine, diet, ecology and other fields, and is actually a plant with multiple values.

It is difficult to ascertain the price of broccoli in the city, and it varies from time to place. I have heard that, in normal times and places, the price of broccoli is about twenty dollars per catty. However, if the weather is bad, and the year is rich and sorry, its price fluctuates and fluctuates.
In the year of its harvest, the fields are widely harvested, the warehouses are full, and the city is full of broccoli. The price may be slightly reduced, or it may be reduced to about fifteen dollars per catty. It is common sense to cover more and be cheap.
In times of famine, droughts are wreaking havoc, floods are rampant, and the harvest of crops is lost, and the yield of broccoli is sharply reduced. There are many people in the city who want it, but there are few people who supply it, so the price rises. Each catty may rise to more than thirty yuan, or even up to forty yuan, and the people will suffer.
In the four corners of the country, the terroir is different, and the price is also different. The land of fertile soil produces rich grain, and the price is always flat; while in remote areas, traffic is blocked, and it is difficult to transfer, so the price must be high.
And the management of the merchants also involves the price. He may be hoarding and waiting for the price to be sold, and the price will change accordingly. Therefore, if you want to know the exact price of the bird wheat market, you must carefully observe the years of the time, and judge the rich apologies of the land, and also take into account the actions of the merchants, in order to obtain the approximate.

It is reported in "Tiangong Kaiwu" that sulfur is produced by aluminium stone, and its generation is mostly caused by the symbiosis of stone pavilion fat and various stones. To properly preserve sulfur, you need to pay attention to the following numbers:
First, choose a dry place. Sulfur is afraid of moisture. If it is in a humid place, it is prone to moisture and deterioration. Therefore, it is hidden in a dry and ventilated place to avoid excessive contact with water vapor and maintain its purity.
Second, far fire and heat sources. Sulfur is flammable, and it is very easy to burn in case of open flames and hot topics, and even the risk of explosion. Therefore, the storage place must be kept away from fire and heat sources, such as stoves, heaters, etc., and fireworks are strictly prohibited to prevent accidents.
Third, avoid direct sunlight. Exposure to sunlight for a long time can increase the temperature of sulfur, or cause its physical and chemical properties to change. When placed in a cool place, use shade to block sunlight and protect it from sunlight.
Fourth, sealed storage. Sulfur is volatile and will gradually react with components such as oxygen in the air. Storage in a sealed container can reduce its contact with air, delay the deterioration process, and ensure its stable quality.
Fifth, store separately. Sulfur cannot be stored and mixed with strong oxidants, metal powders, etc., because it comes into contact with these substances or has a violent chemical reaction, endangering safety. It needs to be placed separately and kept at an appropriate distance from other items.
In this way, follow the principles of drying, fire protection, protection from light, sealing, and separate storage to properly preserve sulfur and maintain its performance for a long time for future uses.
