To prepare 2 - (triethylmethyl) pente - 4 - alkynic acid, you can follow the following ancient method:
First take an appropriate amount of propargyne, use liquid ammonia as a solvent, add sodium amide, and the two can react. Hydroalkynes in propargyne are acidic. In the case of sodium amide, hydrogen is replaced by sodium amide to form sodium alkynes. This step of the reaction is quite critical, and the reaction conditions need to be controlled. Temperature and other factors have a great impact on it.
Then, sodium alkyne meets 1-bromo-2-methylpropane. The carbon anions in sodium alkyne have strong nucleophilicity and will attack the carbon connected by bromine in 1-bromo-2-methylpropane. The bromine ions leave to obtain 2- (triethylmethyl) pente-4-ethylene. This step is a nucleophilic substitution reaction. The polarity of the solvent and the concentration of the reactants are all related to the reaction process and yield.
Finally, hydrolysis of 2- (triethyl) pentyl-4-alkyne is carried out, and under suitable acid-base conditions, it is converted into 2- (triethyl) pentyl-4-alkyne acid. When hydrolyzing, it is necessary to pay attention to the amount of acid and base, otherwise the product may be impure.
In this synthesis method, each step of the reaction requires fine control of the conditions. Solvent selection, temperature regulation, and the proportion of reactants are all key, so that the target product 2- (triethyl) pentyl-4-alkynic acid can be obtained in a higher yield.

When storing di- (trimethylphenyl) heptyl-4-ketoacid, the following things must be paid attention to:
First, the storage place should be carefully selected. This compound is extremely sensitive to the temperature and humidity of the surrounding environment. If the temperature is too high, it may cause its chemical structure to change, accelerating the rate of decomposition; if the humidity is too high, it is easy to cause it to get damp, or react with water vapor, causing its purity to be damaged. Therefore, a cool and dry place should be selected. The optimal temperature should be controlled between 15 ° C and 25 ° C, and the relative humidity should be maintained at 40% to 60%.
Second, light is also a key factor. Trimethylphenyl and other structures are exposed to light, or induce luminescent chemical reactions, causing molecular structure changes and affecting their chemical properties. When storing, when contained in an opaque container, or stored in a cabinet protected from light, do not expose to direct sunlight or strong light sources.
Third, avoid contact with incompatible substances. Di- (trimethylphenyl) heptyl-4-ketonic acid has a specific chemical activity, encounters with certain oxidants, reducing agents or acid-base substances, or reacts violently. When storing, do not be in the same room as such substances, and need to be separated from other chemicals to prevent accidental mixing.
Fourth, the material of the storage container should not be ignored. Materials that are chemically stable and do not react with the compound should be selected. Glass containers are usually a good choice because of their good chemical stability and ease of observing the state of the substances inside. However, it should be noted that if the compound has a special reaction to the glass composition, a suitable material should be selected, such as a specific plastic material, but the selected plastic must ensure that it does not interact with the compound.
When storing di- (trimethylphenyl) heptyl-4-keto acids, all the above factors must be carefully considered to ensure the stability and purity of its chemical properties.

At present, the price of (Sanxiang methyl ester) and (4-butyronic acid) in the market is related to various reasons and is quite complicated.
First, the condition of raw materials affects its price. If the raw materials of (Sanxiang methyl ester) are easy to obtain, abundant and affordable, the cost of making (Sanxiang methyl ester) will be reduced, and its price in the market may be reduced. On the contrary, the raw materials are rare and expensive, and their price will rise. The same is true for (4-butyronic acid). The availability, quantity and price of its raw materials are all factors that change the price.
Second, whether the goodness of the craft is involved. If the technical essence of (Sanxiang methyl ester) and (4-butyrynic acid) has less material consumption, high yield, and low waste loss, the cost of finished goods will drop, and the price will also drop. If the technology is poor, the cost will be more and the production will be less, and the price will rise.
Third, the supply and demand of the city is necessary. The market demand for (Sanxiang methyl ester) and (4-butynic acid) is prosperous, and the demand will exceed the supply, and the price will rise. If the supply exceeds the demand, the stock of goods is difficult to sell, and the price may be reduced to sell.
Fourth, the change of government regulation and tax also affects the price. Strict government management, the compliance fee of enterprises will increase, and the price may rise. Tax reduction, cost reduction, price or reduction; tax increase, the opposite is true.
Fifth, the competition situation of the city cannot be ignored. There are many people in the market (Sanxiang methyl ester) and (4-butyric acid), the competition is fierce, and the business is to occupy the market, or the price is reduced to compete. If the competition is delayed, the price may be stable but slightly higher.
To sum up, the market prices of (Sanxiang methyl ester) and (4-butyric acid) are affected by the interaction of raw materials, craftsmanship, supply and demand, political taxation, competition and other factors, and they rise and fall from time to time, which cannot be generalized. Businesspeople need to observe the current situation, the right factors, and respond to changes in price.
