2,3,6,7-tetrahydro-1H,5H-pyrido[3,2,1-ij]quinoline-9-carbaldehyde

"Tiangong Kaiwu" has a saying: "Two gas, three things, six elements, seven governments, four elephants, one gas is connected, one yin and one yang, movement and static are caused by each other. Yin and yang sympathize, and all things transform." Today there is a question: "2% 2C3% 2C6% 2C7 - four gas - 1H% 2C5H - to it [3% 2C2% 2C1 - ij] Reflective - 9 - What is the main use of methane?"
Methane is the main component of natural gas, biogas, etc. Its uses are quite extensive. First, it can be used as fuel. In today's society, energy demand is huge, and methane combustion can release a lot of heat energy, which can meet the needs of people's lives and industrial production. The natural gas used for cooking at home is mostly methane, which provides convenience for cooking. In the industrial field, methane also plays a key role in many heating, power generation and other links, promoting the orderly progress of various production activities.
Second, methane can be used as a chemical raw material. In the chemical industry, methane can be converted into many important chemical products through a series of chemical reactions. For example, through steam reforming reaction, synthesis gas can be generated, which is the basic raw material for the preparation of methanol, ammonia and other chemicals. Methanol can be further used to make plastics, fibers, coatings and many other products, which has a profound impact on the development of modern industry.
Third, in the agricultural field, the main component of biogas is methane. In rural areas, biogas is produced by collecting human and animal manure, crop straw, etc. for anaerobic fermentation, which not only realizes waste resource utilization, but also provides farmers with clean and renewable energy, and contributes to the green and sustainable development of agriculture.
Therefore, methane plays an indispensable and important role in energy supply, chemical production and agricultural development, and makes great contributions to the progress and development of human society.

Eh! For ethane, its molecules are composed of two carbon and six hydrogen. Its physical properties are particularly observable.
Looking at its phase state, ethane is gaseous at room temperature and pressure, with a peaceful nature and not very active. Its color is pure and transparent, and its taste is light, and ordinary people can hardly feel it when they smell it.
As for the boiling point, it is about minus 88.6 ° C, and the melting point is minus 183.3 ° C. Such a low temperature state makes it difficult to leave traces in ordinary environments.
Furthermore, the density of ethane is less than that of air. If it is released in the air, it will rise up. And it is difficult to dissolve in water. If it is foreign in water, it is difficult to melt with water. < Br >
Fuethane is a member of the alkane family and has alkane commonalities. Its chemical properties are stable, and it usually does not combine with strong acids, strong bases and strong oxidizing agents. In case of fire, it can burn violently, generate carbon dioxide and water, and release a huge amount of heat at the same time, which is also useful in the field of energy.
And because of its simple and orderly structure, the single bond of carbon and carbon in the molecule is stable, so that the reaction can only occur under specific conditions, either by heating or with the help of catalysts. This is a summary of the physical properties of ethane. It is widely used in the chemical and energy industries and should be carefully observed.

If you want to make ethane, you should start with 2,3,6,7-tetrahydro-1H, 5H-to-fluorene, and you need to borrow the number of nine (or have a specific meaning, not detailed, due to the limited information).
To get ethane, you can explore it from the method of organic chemistry. Take the common reaction path, or you can use the method of catalytic hydrogenation. First make this 2,3,6,7-tetrahydro-1H, 5H-to-fluorene in front of a suitable catalyst, such as platinum, palladium and other noble metal catalysts, and introduce hydrogen under appropriate temperature and pressure conditions. The reaction principle is that hydrogen atoms are added to the unsaturated bond of fluorene. Hydrogen atoms are gradually added to specific positions of fluorene, so that the unsaturated structure is gradually saturated, and finally ethane is obtained.
Or other organic reactions can be used, such as first performing a specific functional group transformation of the fluorene derivative, introducing a group that can further react, and then eliminating, rearranging and other series of reactions to gradually construct the structure of ethane. However, these paths require fine regulation of the reaction conditions, and have strict requirements on the purity of the reactants and the order of the reaction.
In actual operation, the temperature, pressure, catalyst dosage and activity all have a significant impact on the reaction rate and yield. If the temperature is too high, it may cause frequent side reactions; if the temperature is too low, the reaction rate will be delayed. The pressure also needs to be adjusted to facilitate the participation of hydrogen and the advancement of the reaction. The activity maintenance and regeneration of the catalyst are also key, which is related to the sustainability and economy of the reaction. In this way, a good method for producing ethane can be obtained.

Looking at this question, it is mentioned that "what is the market price of 2,3,6,7-tetrahydro-1H, 5H-to-its [3,2,1-ij] light-9-methyl ether". This involves quite specialized chemicals, and its market price is difficult to describe.
Because the price of chemical substances is often affected by many factors. First, the cost of raw materials is the key. If the raw materials required to synthesize this 2,3,6,7-tetrahydro-1H, 5H-to-its [3,2,1-ij] light-9-methyl ether are scarce and difficult to find, or the cost of acquisition is high, which will inevitably lead to the price of the final product rising. Second, the simplicity of the preparation process also affects the price. If the preparation of this substance requires complex steps, harsh reaction conditions, such as high temperature, high pressure, or special catalysts, it will increase production costs, which in turn will increase market prices. Furthermore, the situation of market supply and demand is also an important factor. If the market demand for this substance is strong and the supply is limited, the price will rise; conversely, if the supply exceeds the demand, the price may decline.
In addition, different manufacturers will set different prices due to differences in technical level, scale efficiency, etc. Moreover, regional factors cannot be ignored. The market environment and transportation costs in different regions will also fluctuate. Therefore, in order to know the exact market price of this 2,3,6,7-tetrahydro-1H, 5H-to-its [3,2,1-ij] light-9-methyl ether, it is necessary to check the chemical market information in detail, consult professional chemical product suppliers or related industry personnel, and comprehensively consider various factors to obtain more accurate price information.

"Tiangong Kaiwu" says: "Where ethyl sulfur is stored, it needs to be stored in a cool and dry place, away from open flames, and separated from other things. Its nature is lively, it is easy to merge with various things, and it changes when heated, so it cannot be exposed to the sun, nor can it be close to the heater. The storage device needs to be strong and dense to prevent it from escaping. Place it in a place that is dry and protected from water. If it is soaked in water, it will definitely change. This is the key to the storage of ethyl sulfur." Those who cover ethyl sulfur are flammable and active. When storing, they need to be careful and keep these rules to protect them.
