The synthesis method of methoxybenzene has been used in ancient times, and there are many methods, each with its own wonders.
First, phenol is used as the starting material. First, phenol is reacted with sodium hydroxide to form sodium phenol. The nucleophilic substitution reaction between sodium phenol and methane chloride occurs under suitable conditions. This reaction needs to be carried out at a certain temperature and pressure, and an appropriate catalyst is required, so methoxybenzene can be obtained. The reaction mechanism is that the phenoxy negative ion of sodium phenol acts as a nucleophilic reagent to attack the carbon atom of methane chloride, and the chlorine atom leaves to form methoxybenzene.
Second, it can be synthesized by phenyl ether method. Benzene is reacted with methanol under the action of an acidic catalyst. Commonly used acidic catalysts such as concentrated sulfuric acid, hydrofluoric acid, etc. In this reaction, methanol is protonated under acidic conditions to form an active electrophilic reagent, which then undergoes an electrophilic substitution reaction with benzene to generate methoxybenzene. However, this method requires attention to the control of the reaction conditions, because the acidic catalyst is highly corrosive, and the reaction may produce a variety of by-products, which need to be carefully separated and purified.
Third, halogenated benzene is used as raw material. If bromobenzene reacts with sodium methoxide in a suitable solvent, the introduction of methoxy groups can be achieved. This reaction is a nucleophilic substitution reaction of halogenated hydrocarbons. The methoxy negative ion of sodium methoxide attacks the carbon atom of bromobenzene, and the bromine ion leaves to form methoxybenzene. Choosing the right solvent has a great impact on the reaction. Commonly used solvents such as dimethyl sulfoxide, N, N-dimethylformamide, etc., can improve the reaction activity and promote the reaction.
Fourth, by aryl diazonium salt method. First, aniline is converted into diazonium salt through diazotization reaction, and then the diazonium salt reacts with methanol under the action of appropriate reducing agent and catalyst to obtain methoxybenzene. This method has relatively many steps, and attention should be paid to the control of the conditions of the diazotization reaction. Due to the more active nature of diazonium salt, improper operation can easily lead to danger.
The above methods have their own advantages and disadvantages. In actual synthesis, it is necessary to comprehensively consider many factors such as the availability of raw materials, the difficulty of reaction conditions, and the purity requirements of the product to choose the most suitable synthesis method.

Ethane is an alkane compound with the following physical properties:
First, looking at its state, under normal temperature and pressure, ethane presents a gaseous state. Although there is no special record of ethane in "Tiangong Kaiwu", the book discusses many examples of changes in the state of substances, such as burning stone into ash, etc. It can be inferred that the state of substances is different under different conditions, while ethane is normally gas, which is easy to diffuse and difficult to leave traces in the atmosphere.
Second, when it comes to color and smell, ethane is colorless and odorless. This property is just like some pure natural substances recorded in the book. It has no variegated odor and is invisible in nature. It is not easy for people to directly detect it. Its existence can be detected by specific means.
Third, its solubility is observed. Ethane is extremely difficult to dissolve in water. This is similar to some of the fat-soluble substances contained in "Tiangong Kaiwu" that are insoluble in the water phase. Due to the characteristics of molecular structure, the force between water molecules is weak, so it is insoluble in water, and mostly exists in the gas phase or miscible with non-polar solvents.
Fourth, compared with the density, the density of ethane is less than that of air. As mentioned in the book, some lightweight substances can float on air or other media. Due to the density, ethane will float in the air, and if there is leakage, it will spread upward.
In addition, the melting point of ethane is -183.3 ° C, and the boiling point is -88.6 ° C. Such a low melting boiling point allows ethane to maintain a gaseous state at common ambient temperatures, and only when the temperature drops to a very low level can it liquefy or even solidify. This is similar to the principle that many substances involved in "Tiangong Kaiwu" undergo phase transitions due to temperature changes, all of which are influenced by the key factor of temperature.

There are many things to pay attention to when storing and transporting methyl ether.
First, methyl ether has flammable characteristics, and its ignition point is quite low. It will explode when exposed to open flames and high heat energy in the air. Therefore, the storage place must be kept away from fire and heat sources, and explosion-proof lighting and ventilation facilities should be used. It is strictly forbidden to use mechanical equipment and tools that are prone to sparks.
Second, the storage pressure of methyl ether is also the key. Because it is gaseous at room temperature and pressure, it is mostly stored and transported in the form of compression or liquefaction. The storage container must be able to withstand the corresponding pressure, and the container and pipeline should be checked regularly to prevent leakage. If the pressure control is improper, the container may be at risk of rupture, causing a large amount of methyl ether leakage, causing serious consequences.
Third, methyl ether also has requirements for the temperature of the storage environment. If the temperature is too high, the vapor pressure of methyl ether will increase, causing the pressure in the container to rise, increasing the risk of leakage and explosion. Therefore, the storage place should be cool and ventilated, and the temperature should be maintained within a suitable range.
Fourth, during transportation, it is necessary to ensure that the methyl ether container is stable to prevent collisions and falls. At the same time, the transportation vehicle should also be equipped with corresponding fire fighting equipment and leakage emergency treatment equipment. The transportation personnel must be professionally trained and familiar with the characteristics of methyl ether and emergency treatment methods.
Furthermore, the storage area of methyl ether should be separated from oxidants and acids, and should not be mixed. Because of its active chemical properties, contact with certain substances may cause violent reactions.
In short, during the storage and transportation of methyl ether, it is necessary to strictly adhere to safety regulations and operate cautiously, so as to effectively avoid risks and ensure the safety of personnel and the environment.

The market price of methylbenazole is the result of the interaction of various factors in the business market. Covering the world's business is not a single effort, but is controlled by supply and demand, cost, and decrees.
First talk about the state of supply and demand. If everyone in the world is thirsty for methylbenazole, and there are many people who want it, and the supply of the city is sparse, like the clouds in the face of a severe drought, its price will rise, just like water, and the trend of nature is the same. On the contrary, if supply exceeds demand, piled up in the city, and there are few people who are interested, the price should drop. This is also common sense.
The number of costs is also the key. The manufacture of methylbenazole requires all kinds of materials. If the price of methylbenazole is too high, or if the cost of manpower, equipment consumption, and factory rent all increase, the cost of this fabrication will be too high. Businesspeople pursue profits, and since the cost rises, they must seek compensation from the selling price, and the market price will rise. If the materials are abundant, the price is flat and the labor cost is saved, and the cost is low, the price may also drop.
Furthermore, the application of the decree is related to the market. If the court issues laws, increases taxes on methylbenazole's business, or restricts its production, all this will increase the burden on merchants, and the price will have to rise. If the government orders incentives, reduces tax exemptions, and helps its business prosper, so that the production increases and the cost decreases, the price may be stable and decline.
And the market is changing, and the competition in the same industry cannot be ignored. All businesspeople are eager to make a profit, competing to sell metabazole, or there are those who are attractive at a good price, or those who are trustworthy with good quality. The more intense the competition, the more frequent the fluctuation of the price. If there are few businesspeople, and they dominate the market, their price can be set at will, but this is abnormal.
Overall, the market price of metabazole changes with supply and demand, costs, decrees, and competition, just like a boat on the sea, with the ups and downs of the wind and waves. To know the exact number of its price, you must carefully consider all the situations and weigh them before you can get a rough idea.
