Sanxiang methyl ether is an organic compound and is widely used in the chemical industry. To synthesize 3-methyl ether, there are several common methods:
One is the Williamson synthesis method. This is a classic ether synthesis method, which is obtained by reacting sodium alcohol or sodium phenol with halogenated hydrocarbons. Specifically, 3-methyl alcohol is first reacted with sodium metal to form sodium alcohol, and then the sodium alcohol is reacted with halogenated hydrocarbons (such as halomethane) in a suitable solvent (such as anhydrous ethanol, etc.) under mild heating conditions. During the reaction, the oxygen anion of sodium alcohol attacks the carbon atom of the halogenated hydrocarbon nucleophilically, and the halogen ion leaves to form 3-methyl ether. The advantage of this method is that the reaction conditions are relatively mild and the yield is quite high; however, halogenated hydrocarbons need to be carefully selected, and if the halogenated hydrocarbons have complex structures, side reactions such as elimination reactions may be initiated.
The second is the alcohol dehydration method. Using 3-methyl alcohol as raw material, heating dehydration in the presence of acidic catalysts (such as concentrated sulfuric acid, p-toluenesulfonic acid, etc.). At a suitable temperature, 3-methyl alcohol intermolecular dehydration generates 3-methyl ether. This method is relatively simple to operate, but the reaction temperature needs to be strictly controlled, otherwise it is easy to produce by-products such as olefins. And concentrated sulfuric acid is highly corrosive, and special care is required during operation.
The third is the phase transfer catalytic In this method, reactants in different phases (such as aqueous and organic phases) can be effectively contacted and reacted by means of a phase transfer catalyst. For example, when synthesizing 3-methyl ether, a quaternary ammonium salt phase transfer catalyst can be selected. In an water-organic two-phase system, sodium alcohol is in the aqueous phase, and halogenated hydrocarbons are in the organic phase. The phase transfer catalyst can transfer sodium alcohol from the aqueous phase to the organic phase and react with halogenated hydrocarbons to form 3-methyl ether. This method can speed up the reaction rate and improve the yield, and the reaction conditions are relatively mild and environmentally friendly. < Br >
The methods for synthesizing 3-methyl ether have their own advantages and disadvantages. In practical application, it is necessary to consider many factors such as the availability of raw materials, the requirements of reaction conditions, and the purity requirements of the product, and carefully select the appropriate synthesis method.

Trimethyl ether, or trimethyl ether, is an organic compound. As for the physical properties of methyl ether, it is a colorless gas with a special odor of ether.
Its boiling point is quite low, about -24.9 ° C. Above this temperature, trimethyl ether will change from liquid to gaseous. This property makes trimethyl ether mostly gaseous at room temperature and pressure. Its melting point is -141.5 ° C. When the temperature drops below this point, trimethyl ether will condense into a solid state.
The density of trimethyl ether is slightly lighter than that of air, about 1.97 kg/m ³ (under standard conditions), so it will drift upward when there is no external force interference. In terms of solubility, it can be slightly soluble in water, but it can be miscible with most organic solvents such as ethanol and ether in any ratio.
In addition, trimethyl ether is flammable, and it can cause combustion and explosion when exposed to open flames and high heat in the air. Its vapor and air can form an explosive mixture, and there is a danger of combustion and explosion when exposed to heat sources and open flames. It reacts violently with oxidants. The gas is heavier than air and can spread to a considerable distance at a lower place. In case of fire, it will catch fire and backfire.
To sum up, trimethyl ether has physical properties such as colorless gas, special odor, low boiling point, lighter than air, slightly soluble in water, soluble in organic solvents and flammable. When used in chemical and other fields, special attention should be paid to its characteristics to ensure safety.

Trialkyl methyl ether, among which methyl ether is an example. The chemical properties of methyl ether are as follows:
Methyl ether is a colorless and flammable gas at room temperature and pressure, and smells with a weak aroma unique to ethers. Its boiling point is quite low, about minus 23.6 degrees Celsius, which makes it easy to volatilize into a gaseous state at room temperature.
When it comes to flammability, methyl ether is very easy to burn, and it can cause a violent combustion reaction when exposed to open flames or hot topics in the air. It can form a highly explosive mixture with air, and there is a risk of explosion when exposed to fire sources. When burned, carbon dioxide and water are formed, and the chemical equation is:\ (2CH_ {3} OCH_ {3} + 7O_ {2}\ stackrel {ignited }{=\!=\!=} {2} + 6H_ {2} O\).
Methyl ether also has certain solubility, which can be dissolved in water, but the solubility is limited, and it is more soluble in organic solvents, such as ethanol, ether, acetone, etc. This is because the molecular structure of methyl ether has good affinity with organic solvents.
From the perspective of reactivity, methyl ether is relatively stable. However, under specific conditions, such as high temperature, high pressure and the presence of appropriate catalysts, chemical reactions can also occur. For example, hydrolysis can be carried out, and methanol is formed by reacting with water under the action of acidic catalysts:\ (CH_ {3} OCH_ {3} + H_ {2} O\ stackrel {H ^{+}}{\ rightleft harpoons} 2CH_ {3} OH\), but this reaction is reversible, and the degree of reaction is affected by many factors.
can also be substituted with halogens. Under light or heating conditions, the hydrogen atoms in the methyl ether molecule can be gradually replaced by halogen atoms to form halogenated methyl ethers and other derivatives. The chemical properties of
methyl ether make it widely used in the chemical industry. It can be used as a solvent, refrigerant, and is also an important raw material for organic synthesis.

Guanfu Sanxiang methyl ester, its price in the market, often varies with time, place and quality.
In today's world, there are many business routes, and the colonization of goods is staggered. The price of methyl ester, like the waves of rivers and lakes, is not fixed. However, roughly speaking, the price of trimethyl ester in the market is often between [X] and [X].
The fluctuation of this price is due to various reasons. First, in the place of origin, if the mountains and forests are abundant and the materials are easy to collect, the price may be flat; if the place of origin is poor and difficult to harvest and transport, the price will rise. Second, the supply and demand of the city, the demand is abundant and the supply is small, the price is high; if the supply exceeds the demand, the price is low. Third, the rules of current affairs and the system of taxation are also involved in the price. If the tax is heavy, the merchant will change to the price, which will increase it; if the tax is light, the price will decrease.
Also, the craftsmanship is clumsy, and it is also related to the price. Those who are good at fine work are of high quality and expensive; those who are shoddy are of poor quality and cheap. Therefore, if you want to know the exact price, you must carefully observe the market conditions and study various factors before you can get it. Then it is stated, but the approximate number, the actual price should be subject to what is done in the market.
