"Tiangong Kaiwu" says: Arsenic, that is, letter stone, the name of the living is Pi Huang, and the name of the refiner is arsenic. Arsenic-2-arsenous acid, its main uses are two.
One is in the way of medicine. Although arsenic is highly toxic, it is also used in moderation, and it also has medicinal power. Ancient healers, with its fierce nature, treat deep and chronic diseases. Such as scabies, syphilis and other malignant diseases, an appropriate amount of arsenic can be used externally to erode sores and remove rot, so that poisonous evil can go out, and sores are gradually healed. Arsenic is also used as medicine to treat malaria and other diseases, with its toxicity to attack evil and make malaria evil dissipate. And modern medical research has also found that arsenous acid has a unique effect in the treatment of leukemia, which can induce the differentiation and apoptosis of leukemia cells, and pave the way for the treatment of blood syndrome.
Second, in the industrial field, arsenous acid is also quite important. In the metallurgical industry, it can be used as a refining agent. When smelting metals such as lead and copper, adding an appropriate amount of arsenous acid can remove impurities and improve the purity and quality of the metal. Because it can chemically react with impurities to produce substances that are easy to separate. In glass manufacturing, arsenous acid is used as a clarifying agent. When glass is smelted, many bubbles will be produced, which affects the transparency and quality of the glass. Arsenous acid can promote the discharge of bubbles, making the glass uniform and crystal clear. In addition, in the manufacture of some pesticides, arsenic acid can be used as one of the raw materials to control pests and protect crop growth. However, due to the severe toxicity of arsenic, when using it, be careful to prevent harm to life.

The method of making jelly has been known in ancient times, and now I will say the second, for you to enjoy.
First, start with rice and wheat. Take a few pieces of rice and wheat first, wash them clean, soak them in water, and wait for them to be moisturized. Remove them from the basket, cover them with a damp cloth, and sprinkle them with water often to make them germinate. The sprouts are several inches long, dry them in the sun, and grind them into a fine powder. This is malt powder. Then choose high-quality glutinous rice, cook them as cooked rice, and wait for them to cool slightly. Mix them with malt powder, and seal them in an urn. Place them in a warm place and melt over time, during which it is appropriate to check their temperature, and do not overheat them. When the saccharification is complete, filter it with a cloth, remove its dross, leave its clear liquid, boil and concentrate until it is thick and sticky, and the taste is complete.
Second, use millet for it. Choose the millet with full particles, fry until slightly yellow, and the aroma escapes. After grinding, boil it in water, and cook it for a long time until it is rotten. In addition, prepare the end of Qu, according to a certain amount, wait for the millet soup to be slightly cool, stir it well into the end of Qu, and also put it in an urn to seal. Let it stand in a suitable place to ferment and saccharify. When the saccharification is completed, filter the soup with a cloth and boil it with juice. When boiling, you need to stir it frequently to prevent it from being burnt, and the heat is moderate until the texture is suitable.
Both of these are ancient methods of making jelly. Although the steps are a little complicated, you can get a sweet jelly by following them. The ancestors of the past created this skill with wisdom and have been passed down to this day. It is also a treasure of food culture.

In today's world, asking what the price of pentazole-2-propionic acid is in the market is one of the questions related to business and people's livelihood. Fupentazole-2-propionic acid is widely used in the chemical industry, and it is indispensable in the fields of agricultural protection, medical preparation, etc.
However, its price is determined, and it cannot be generalized. It is made by many factors. First, the supply and demand of raw materials are also. If the raw materials required for its preparation are abundant in the production area and the supply is not at risk, the cost may be slightly reduced, and the price should be stable, or there may be a downward trend; if the raw material production area encounters disasters, or the supply is sharply reduced due to government orders or strategies, the price will rise, just like water, the trend is also.
Second, the precision of the craftsmanship is also related. If the workshop uses exquisite methods to reduce its energy consumption, increase its output, and produce high-quality products, it can be sold at a better price in the market; conversely, if the craftsmanship is crude, the yield is low, and the quality is not enough, the price may be difficult to say high, and may be abandoned by the market.
Furthermore, changes in the times and regulations of the government also affect its price. In this world, all countries place great importance on environmental protection. If the preparation of pentazole-2-propionic acid violates environmental protection regulations, it will be restricted and banned, its production will shrink, and the price will rise along with it; and if the time is wartime, or trade barriers are high, logistics is not smooth, supply and demand are unbalanced, and the price fluctuates greatly.
Therefore, if you want to know the exact price of pentazole-2-propionic acid, when you carefully consider the factors of raw materials, processes, current conditions, and government orders, and weigh and compare them, you can get a rough estimate. It is not speculative.

"Tiangong Kaiwu" cloud: Arsenic, that is, letter stone. The arsenous acid it contains, stored in the stone, is toxic. The key to its storage is to seal. Arsenic is strong in nature and easy to merge with other things. If it is not sealed, it is not suitable to encounter moisture, gas, or cause qualitative change, toxicity or increase or decrease. Sealed utensils should be made of porcelain jars and glass bottles. The texture is dense and can prevent the infiltration of gas and liquid.
Where arsenic is hidden, it must be dry and cool. Wet is easy to dissolve, hot is variable, and its quality is damaged. It is suitable for high dryness, away from fire sources and water sources, and should not be stored on the same level as food and medicine to prevent accidental touch and ingestion. In addition, arsenic is highly toxic, and the storage place must be locked and protected, managed by special personnel, and records are kept for entry and exit to prevent loss and cause disasters. When taking it, you should also be cautious and measure it according to the party, and do not make a slight mistake.
Those who hide arsenic must abide by the above regulations, so that the security guards are safe, and do not use this highly toxic thing as a disaster to the world.
