"Tiangong Kaiwu" says: "Where the well water comes from far away, its color is green, its taste is delicious, and the water is superior, it can be boiled for tea, wine, and food, and everything is good. Ruofu River water, from west to east, travels thousands of miles, the flow of Nabai River, its color is yellow, its taste is light, its quality is heavy, it can be used for diet, it can be raccoon clothes, and it can be irrigated. As for seawater, its color is white, its taste is salty, and its quality is the heaviest, it cannot be used for diet, but it can be used for salt, it can be boiled to produce alum, and it can be used as medicinal bait." 2%2C3%2C5-%E4%B8%89%E6%B0%9F%E5%90%A1%E5%95%B6%E7%94%B1%E6%B5%B7%E6%B0%94%E8%87%AA%E5%87%BA%E8%80%8C%E6%B5%81%E6%88%90%EF%BC%8C%E5%85%B6%E6%B0%B4%E8%B4%A8%E4%B8%AD%E7%AD%89%EF%BC%8C%E6%9C%80%E9%80%94%E7%94%A8%E4%BA%8E%E5%85%AC%E4%BC%97%E7%94%A8%E6%B0%B4%E3%80%82
Because of the land it flows through, it is mostly a place where people live, and the water is rich and easy to use. This water is either used for drinking, so that people can quench their thirst and maintain health; or for irrigation, to help crops thrive and protect the foundation of people's livelihood; or for washing, to keep clothes clean and maintain a tidy life. Although its water quality is not pure to pure, it is indispensable for people's daily use. And where these three waters converge, they often form prosperous towns, which shows its importance to people's livelihood and is the fundamental water source on which people depend for their livelihood.

First of all, it is strong. Two, three, five - three directions are as solid as a rock, and the ordinary power is difficult to damage. Gu Yun: "The strength of gold and stone can still be carved, but the three directions to it, the strength is tens of thousands of catties without breaking, and the sharp tool can be added without a trace." Just like the casting of divine work, its firmness comes from the density of the inner structure. The molecules and atoms are interlocked like mortise and tenon, and it is as stable as Mount Tai, which can withstand the wind and rain, and the earth shakes.
The second is its guide. This substance is quite unique in the conduction of electricity and heat. The conduction of electricity is like a flash of light, and it is instantaneous for thousands of miles, and the resistance is almost non-existent. The transfer of heat is also as fast as thunder, and one side is heated, and the whole body is warm in an instant. The ancients said: "The trend of heat is like a river of water, and the direction of electricity is like a star shining in the sky." With its conductivity, if used in utensils, it can make electrical appliances efficient, and heat tools warm up quickly, which is actually a wonderful gift of creation.
Furthermore, it changes. Two, three, five-three can be used in different environments, and it can develop different forms. In case of high temperature, it can be turned into soft water, which is agile and inflexible; in case of severe cold, it condenses into hard ice, which is very hard. It is like knowing the way the world changes, and it changes with the environment The ancient wise man sighed: "Things move with the environment, and these three directions are the essence of change, which cannot be easily controlled by human beings."
Also said to be dense. Its density is moderate, light but not floating, heavy but not falling. Placed in water, it can rise and fall freely, and seems to have spirituality. It is easy to carry and has a sense of stability. It can be used in boats and horses to keep it stable and agile.
Overall, the physical properties of 2%2C3%2C5-%E4%B8%89%E6%B0%9F%E5%90%A1%E5%95%B6 are very wonderful, or a treasure bred by heaven and earth. If it can be used well, it will definitely bring endless benefits to the world.

2%2C3%2C5-%E4%B8%89%E6%B0%9F%E5%90%A1%E5%95%B6, there are many ways to synthesize it.
First, chemical synthesis can be used. With suitable raw materials, precise chemical reaction steps can be carried out. For example, select specific organic compounds, under suitable reaction conditions, such as controlling temperature, pressure and catalyst type and dosage, etc., to promote specific bonding and transformation between molecules, and then synthesize the target. If the raw materials are selected properly and the reaction conditions are precisely controlled, this approach can be efficiently obtained.
Second, biosynthesis can also be done. Many organisms in nature have the wonderful ability to synthesize specific substances. With the help of certain microorganisms or plant cells, their own metabolic mechanisms can be used. By culturing these organisms and giving them suitable nutrients and environmental conditions, they can be induced to synthesize the 2%2C3%2C5-%E4%B8%89%E6%B0%9F%E5%90%A1%E5%95%B6 we need. Although this method is relatively mild, it requires a deep understanding of the growth characteristics and metabolic pathways of organisms.
Third, the method of physical synthesis. For example, the use of some special physical fields, such as electric fields, magnetic fields or lasers, acts on the relevant substances to cause changes in their physical properties, which in turn prompts molecules to rearrange and combine to achieve the purpose of synthesis. However, this method requires high equipment and technology, and requires precise control of physical parameters.
Furthermore, several methods can be combined. First, the basic structure is initially constructed by chemical synthesis, then the molecular structure is fine-tuned by biological synthesis, and finally the performance is optimized by physical synthesis. In this way, it may be possible to synthesize 2%2C3%2C5-%E4%B8%89%E6%B0%9F%E5%90%A1%E5%95%B6 better.
In short, there are various methods for synthesizing 2%2C3%2C5-%E4%B8%89%E6%B0%9F%E5%90%A1%E5%95%B6, and appropriate methods need to be carefully selected according to actual needs, resources and technical conditions in order to achieve the goal of synthesis efficiently and with high quality.

Wen Jun asked 2% 2C3% 2C5 - Sanjiang to its price in the market. The price of these three in the market varies from time to time, and also varies from quality, and also varies according to the trend of supply and demand.
Fu 2% 2C3% 2C5 - Sanjiang to it, if the quality is good and the time needs to be prosperous, the price will rise. Cover everyone's competition to buy, the price will be high. If in a prosperous year, the production is abundant and needs to be flat, the price may be stable. However, if the supply exceeds demand and the quality is normal, the price may drop.
And the distance of the place, the difficulty of transportation, is also related to the price. If the origin is far away, the transportation to the market costs a lot, the price is also high. If you are close to the city, it will be easy to transport and save money, and the price will be low.
The profit of the merchants also affects the price. Those who are good at plotting, observe the changes in the city, and stock up on the time, sell at a high price, and collect at a low price, in order to get a good profit. It is difficult to determine the price, but only in the market at the time can you know the exact price. To know the details, when you go to the city in person, consult the merchants, and observe the market, you can get the actual price.

2-Hydroxypropionic acid, often called lactic acid, this substance should be stored in a cool, dry and well-ventilated place, away from fire and heat sources, and should be stored separately from oxidants and alkalis. Do not mix storage. The storage area should be equipped with suitable materials to contain leaks. Because of its certain corrosiveness and irritation, the storage container should be corrosion-resistant and well sealed to prevent volatilization and leakage.
3-Hydroxypropionic acid is relatively rare and demanding on the storage environment. It requires a low temperature, dry and oxygen-free environment. Generally, a special sealed container is used to fill inert gases such as nitrogen to prevent oxidation and polymerization. Due to its active chemical properties, it is easy to deteriorate under heat, light or contact with impurities. The storage place should be protected from strong light and high temperature, and the storage status should be checked regularly.
5-hydroxyvaleric acid should be stored in a cool and ventilated warehouse, away from fire and heat sources. The storage temperature should not exceed 30 ° C. It should be stored separately from oxidants, reducing agents and alkalis to avoid mixed storage. Use explosion-proof lighting and ventilation facilities, and prohibit the use of mechanical equipment and tools that are prone to sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials. Because of its certain flammability and chemical activity, sealing and fire protection and explosion protection are the keys.
These three hydroxy acids have different storage conditions due to differences in structure and properties. However, moisture-proof, oxidation-proof, fire-proof and explosion-proof, and avoiding contact with incompatible substances are all important principles, so as to ensure storage safety and material stability.
