1% 2C2% 2C3% 2C4% 2C5 should refer to the five elements, that is, metal, wood, water, fire, and earth. The five elements have a corresponding relationship with the five internal organs, five parties, five flavors and many other things, and their characteristics are different.
Gold is strong and hard, and has the ability to kill and restrain. "Shang Shu Hongfan" said: "Gold is called from revolution." From revolution means change, symbolizing that metal can be cast into tools, and has the ability to kill all things. Its nature is strong, and its qi is fierce.
Wood is made of clockwork. "Shang Shu Hongfan" said: "Wood is called straight." Curved straight means that trees can be bent and straight, grow upward, have the power to grow hair, and have the ability to stretch and soften.
Those who are water, moisturize and descend. "Shang Shu Hongfan" said: "Water is moisturizing." Moisturizing means that water has the nature of moisturizing all things and flowing downward. Its nature is weak, but it can overcome rigidity.
Those who are on fire, hot and upward. "Shang Shu Hongfan" said: "Fire is hot and upward." On fire, fire has the appearance of heat, and rises upward, with bright and warm nature.
Those who are on earth, carry biological and biochemical materials. "Shang Shu Hongfan" said: "Soil is harvested." Harvest refers to the land that can grow crops, has the ability to nurture all things and carry them, and its nature is honest.
As for the "physical properties of 6-methylbenzene", methyl benzene, usually nail benzene. Toluene is a colorless clear liquid with a benzene-like odor. Melting point - 94.9 ° C, boiling point 110.6 ° C, relative density 0.866 ° C, flash point 4.4 ° C. Insoluble in water, miscible in most organic solvents such as benzene, alcohol, ether, etc. Its vapor is heavier than air and can spread to a considerable distance at a lower place. In case of open flame, it will lead to backburning.
Toluene is volatile and easily volatilized into the air at room temperature. Because it is an organic compound, intermolecular forces determine that it has certain solubility characteristics and has good solubility in organic solvents. Due to its physical properties, it has many uses in chemical production and other fields, such as as solvents and raw materials.

1% 2C2% 2C3% 2C4% 2C5 refers to the "five oceans", usually referred to as the "five oceans" are the Pacific Ocean, Atlantic Ocean, Indian Ocean, Arctic Ocean and Southern Ocean. As for the "methyl benzene" referred to in 6, its chemical properties are not stable.
Methylbenzene, also known as toluene, is volatile and flammable. Under normal temperature and pressure, toluene is very easy to vaporize, and when mixed with air, it can form an explosive mixture. In case of open flame and high heat, it can cause combustion and explosion, which shows that its chemical properties are active and its stability is not good.
From the structural point of view, although the benzene ring of toluene has a certain stability, its methyl is affected by the benzene ring and has a certain activity. The hydrogen atom on the methyl group is easily replaced, and halogenation reactions and oxidation reactions can occur. For example, toluene can be substituted with halogens under light conditions; under certain conditions, toluene can be oxidized to benzoic acid, which indicates that its structure is not very stable and its chemical properties are more active.
In addition, toluene also has many hazards to the human body, which can irritate the respiratory tract and skin. Inhalation of high concentrations of toluene can cause central nervous system inhibition, which is also related to its unstable and volatile properties.
In summary, the chemical properties of methyl benzene are unstable, and special attention should be paid to safety when using and storing to prevent it from causing danger.

1% 2C2% 2C3% 2C4% 2C5, that is, one, two, three, four, and five, is the number of the five elements. The five elements, metal, wood, water, fire, and earth, each have their own characteristics, they are mutually resistant, and the cycle is endless. It has a profound impact on the changes of heaven and earth.
The five elements correspond to the five sides, five flavors, and five colors. The east belongs to wood, blue in color, and sour in taste; the south belongs to fire, red in color, and bitter in taste; the center belongs to earth, yellow in color, and sweet in taste; the west belongs to gold, white in color, and fragrant in taste; the north belongs to water, black in color, and salty in taste.
As for the "production process of Wuhe-6-methylbenzene", the "Wuhe" refers to the place where the five rivers converge, but it is related to the chemical process, or it needs to be combined with local products and geography. And "6-methylbenzene" may be the product of chemical synthesis.
Its production process may start from a specific raw material, through a fine ratio, at a suitable temperature and pressure, in a special reactor, with the effect of a catalyst, so that the raw materials can chemically react. After the reaction is completed, or through multiple processes such as distillation, extraction, and crystallization, the product can be purified to the desired purity.
During this period, it is necessary to strictly abide by the prudence of the ancient law, and to integrate the wisdom of today's people. There must be no slack in the control of the heat, the careful selection of raw materials, and the careful arrangement of the process. In this way, pure 6-methyl benzene can be obtained to meet the needs of all parties, or for medicine, or for chemical industry, all rely on this fine process.

I heard what you asked about the price of hardware and ethanol in the market. Hardware, gold, wood, water, fire, and earth are now replaced by gold, silver, copper, iron, and tin, each of which varies in price according to its quality, use, and source. Gold is more expensive than all things, because it is rare and stable. The price of gold in the market is about hundreds of dollars per gram, which varies from time to time due to market conditions and political conditions. The price of silver is second, ranging from a few dollars per gram to tens of dollars. Copper, iron, tin, copper prices are tens of dollars per kilogram, iron prices are slightly lower, several dollars per kilogram, and tin prices are also tens of dollars per kilogram. However, they all move with the market.
As for ethanol, that is, the pure liquid made of methanol, also known as wood essence. Its price varies depending on the purity and use. Medical ethanol, for the needs of disinfection and sterilization, has a relatively stable price, about tens of dollars per liter. Industrial ethanol, mostly solvents and raw materials, has a slightly lower price, or twenty to fifty dollars per liter. However, the market is volatile, and the price varies due to supply and demand, seasons, and production and transportation. It is difficult to determine the number. It takes time to observe the market situation before we know the details.
