1,2,3,4-Tetrahydro-1-phenylisoquinoline

1% 2C2% 2C3% 2C4 is one, two, three, and four. These four things are often crucial raw materials or symbols in the process of alchemy and refining.
Among the four things, mercury flows and lead is heavy, and the two are often the key things in alchemy. Mercury, with a color like silver, is flexible and changeable, resembling the vitality of life, and often symbolizes variable elements in alchemy, which can react wonderfully with other substances. Lead is heavy in texture and gray-black in color, resembling the stability of the earth. It may be the basis for carrying and fusing other things during alchemy.
Sulfur, with a golden color, is strong and flammable, and is often the driving force for change during alchemy. When it burns, the flame is raging, which can prompt other substances to react violently and promote the process of alchemy.
Carbon, although commonly seen, is also indispensable in alchemy. It has the ability to burn and heat, providing the required high-temperature environment for alchemy, so that all substances can be fused and transformed at high temperatures.
As for the "four qi", it refers to the four characteristics of cold, heat, temperature and cool that a drug or substance has. Cold and heat are opposite, and temperature and cool are similar. Cold can clear heat and reduce fire, heat can remove cold and return to yang, temperature can replenish yang gas, and cool can clear heat and remove trouble. When alchemy, it is necessary to choose substances with corresponding characteristics according to different purposes to reconcile the properties of pills.
"One", in Taoist concepts, often represents the beginning, the original state, and the beginning of all things. In alchemy, it either symbolizes the pure state of the beginning of alchemy, or the ultimate realm of unity pursued.
"Mercury-based different square light", the unique characteristics of mercury, its luster is very different from ordinary things. In the process of alchemy, mercury is specially treated and reacts with other things to produce strange light. This light may be a sign of the refining of medicinal pills, or it may suggest that the medicinal pills contain unique energy. The color and state changes of its light are often closely watched by alchemists to determine whether the process of alchemy is appropriate and whether the medicinal pills have achieved their exquisite work.

1% 2C2% 2C3% 2C4 refers to, when it is one, two, three, and four hydrogens, the one hydrogens are isolated and single, and the properties are more active and easy to react with other substances. Dihydrogens, or in pairs, have slightly more stability. Trihydrogens are polymerized, with unique reaction properties. The coexistence of tetrahydrogens also has different chemical properties.
As for 1-silyl isobutyric acid light, this is due to its specific physical properties. Its performance under light depends on the structure and bond energy of its molecules. When illuminated, the silicon group interacts with the isobutyric acid group, or the migration of electrons and the change of energy levels are induced.
The silicon group itself has the characteristics of a semiconductor. Under light, electron-hole pairs can be generated to participate in photoinduced chemical reactions. The structure of isobutyrate, which contains active groups such as carboxyl groups, affects the polarity and reactivity of molecules. The two are connected, and in the light environment, there may be a phenomenon of charge transfer, which leads to the generation of excited states of molecules, thus showing unique optical and electrical properties. Or in the fields of photocatalysis, photoelectric conversion, etc., with potential applications. This is all based on the degree of understanding, and the actual nature needs to be empirically investigated.

1% 2C2% 2C3% 2C4 shall refer to mono-, di-, tri-, and tetrahydrogens, namely methane ($CH_4 $), ethane ($C_2H_6 $), propane ($C_3H_8 $), butane ($C_4H_ {10} $), and 1 - phenylisobutyric acid (1 - Phenylisobutyric acid). These substances are organic compounds and each has unique chemical properties.
1. Properties of alkanes
1. ** Flammability **: All are flammable and burn in sufficient oxygen to generate carbon dioxide and water. Taking methane as an example, the chemical equation for combustion is $CH_ {4} + 2O_ {2}\ stackrel {ignited} {=\! =\! =} CO_ {2} + 2H_ {2} O $. Combustion can release a lot of heat and can be used as fuel.
2. ** Stability **: Under normal conditions, alkanes are chemically stable and do not react with strong acids, strong bases and strong oxidants such as sulfuric acid, sodium hydroxide, potassium permanganate, etc. This is due to the high energy of carbon-hydrogen bonds and carbon-carbon bonds, which are not easy to break.
3. ** Substitution Reaction **: Alkanes can react with halogens (such as chlorine) under light conditions. For example, when methane and chlorine are irradiated, monochloromethane, dichloromethane, trichloromethane and carbon tetrachloride are gradually formed, and the reaction equation is $CH_ {4} + Cl_ {2}\ stackrel {light }{=\!=\!=} CH_ {3} Cl + HCl $, $CH_ {3} Cl + Cl_ {2}\ stackrel {light }{=\!=\!=} CH_ {2} Cl_ {2} + HCl $, CH_ ${2} Cl_ {2} + Cl_ {2}\ stackrel {light }{=\!=\!=} CHCl_ {3} + HCl $, $CHCl_ {3} + Cl_ {2}\ stackrel {light }{=\!=\! =} CCl_ {4} + HCl $.
Properties of di, 1-phenyl isobutyric acid
1. ** Acidic **: Because it contains carboxyl groups ($-COOH $), it is acidic and can neutralize with bases. If it reacts with sodium hydroxide to form sodium 1-phenyl isobutyrate and water, the chemical equation is $C_ {10} H_ {12} O_ {2} + NaOH\ longrightarrow C_ {10} H_ {11} O_ {2} Na + H_ {2} O $.
2. ** Esterification **: Carboxyl groups can be esterified with alcohols under concentrated sulfuric acid catalysis and heating conditions to form esters and water. If reacted with ethanol, the chemical equation is $C_ {10} H_ {12} O_ {2} + C_ {2} H_ {5} OH\ underset {\ triangle} {\ overset {concentrated sulfuric acid} {\ rightleftharpoons}} C_ {12} H_ {16} O_ {2} + H_ {2} O $.
3. ** Reaction of benzene ring **: The molecule contains benzene ring, and typical reactions of benzene ring can occur, such as halogenation reaction, nitration reaction, etc. Taking the halogenation reaction as an example, it can react with liquid bromine under the catalysis of iron powder to form bromophenyl isobutyric acid.

There are many synthesis methods for 1,2,3,4-tetrahydro-1-naphthyl isopropyl ether, and the advantages and disadvantages of each method vary depending on the specific situation. The following are common synthesis paths:
First, the Williamson synthesis method using halogenated hydrocarbons and sodium alcohol as raw materials. Take 1-naphthol and react with a base to form sodium naphthol. In this step, pay attention to the reaction temperature and the amount of base, otherwise it is easy to cause side reactions. Then react sodium naphthol with 1-halogenated-2-methylpropane in a suitable solvent (such as DMF, acetone, etc.) to obtain the target product by nucleophilic substitution. This method is relatively simple to operate and mild conditions, but halogenated hydrocarbons need to be carefully selected and stored, and the reaction may eliminate side reactions, which affect the yield and purity.
Second, the addition reaction of alcohol and olefin as raw materials. Under the action of 1-naphthol and 2-methylpropene on acidic catalysts (such as concentrated sulfuric acid, p-toluenesulfonic acid, etc.), electrophilic addition occurs to generate 1,2,3,4-tetrahydro-1-naphthyl isopropyl ether. This approach has high atomic utilization and theoretically no by-products are generated, but acidic catalysts are highly corrosive to equipment, and the post-reaction treatment is complicated. The reaction conditions are harsh, so the temperature and pressure need to be strictly controlled. < Br > Third, Foucault alkylation reaction using phenol and halogenated hydrocarbons as raw materials. 1-Naphthol reacts with 1-halogenated-2-methylpropane in the presence of Lewis acid catalysts (such as aluminum trichloride, zinc chloride, etc.), and the product is obtained by electrophilic substitution of aromatics. This method has high reactivity and relatively mild conditions, but Lewis acid catalysts are easy to react with water, and have high requirements for anhydrous reaction systems. And post-treatment will produce a large amount of aluminum or zinc-containing waste, which needs to be properly disposed of.

It is difficult to determine the price range of "tetrahydro-1-naphthyl isobutyric acid light" referred to by 1% 2C2% 2C3% 2C4 in the market. Due to the fickleness of the market, the price is often affected by many factors.
The first to bear the brunt is the trend of supply and demand. If there is a large demand for this product in the market, and the supply is small, the price will rise; on the contrary, if the supply exceeds the demand, the price may be reduced.
Furthermore, the cost of its production is also the key. The price of raw materials, the labor cost of production, and the cost of transportation will all affect the final selling price. If raw materials are scarce and expensive, the production process is complicated, and the transportation is difficult, the cost will be high, and the price will also rise accordingly.
In addition, the current situation, policy regulations, and technological advancements should not be underestimated. The current situation is turbulent, or the supply may be unstable, and the price fluctuates; policy regulation, or tax increases or subsidies are all related to the price; technological innovation, if there are new techniques to reduce the cost of production efficiency, the price may also change.
Therefore, if you want to know the exact price range, you should carefully study the real-time market situation, consult industry players, merchants, or check professional market reports, in order to obtain a more accurate number. However, at this moment, it is difficult to say what the price range is.
