To prepare di- (triethyl) - 4 - p-methoxybenzophenone, there are many methods of synthesis, and each has its advantages and disadvantages. The following will be described in detail.
First, with p-methoxyacetophenone as the starting material, first react with a base to form an enolate, and then alkyl with an appropriate halogenated hydrocarbon. This halogenated hydrocarbon needs to contain triethyl methyl structure. During the reaction process, it is necessary to precisely control the reaction conditions, such as temperature, amount and type of base, which have a great impact on the yield and purity of the product. If the temperature is too high, side reactions occur frequently and the yield decreases; if the amount of base is insufficient, the alkylation reaction is incomplete.
Second, the Grignard reagent method can be used. The Grignard reagent containing triethyl methyl is first prepared, and then it is added to the carbonyl group of p-methoxyacetophenone, and then hydrolyzed to obtain the target product. Although this method is slightly complicated, the reaction selectivity is still acceptable. The preparation of Grignard reagents needs to be carried out in an anhydrous and oxygen-free environment, otherwise it is easy to cause side reactions, resulting in experimental failure. During the addition reaction, the temperature of the reaction system and the ratio of reactants need to be strictly controlled.
Third, with p-methoxybenzoic acid as the starting material, through a series of reactions, such as esterification, reduction, halogenation, and then reacting with reagents containing triethyl methyl, the goal can also be achieved. This route has many steps, but each step of the reaction is relatively easy to control, and the requirements for reaction equipment are not very high. However, the multi-step reaction will lead to a decrease in the total yield, and the separation and purification of the intermediate product is very critical. If the purification is not good, it will affect the quality of the subsequent reaction and the final product.
The above methods have advantages and disadvantages. In actual synthesis, it is necessary to carefully choose the appropriate synthesis method according to the specific experimental conditions, the availability of raw materials, and the requirements for product purity and yield.

Trialkyl methyl, and tetragonal photomethyl borane, both of which are unique chemical substances, each with its own unique physical and chemical properties.
First of all, trialkyl methyl. In its structure, the methyl group is connected to the trivalent central atom, and this structural feature gives it some remarkable properties. In terms of physical properties, it is usually colorless, mostly liquid at room temperature, and has a certain volatility. This is because the intermolecular force is not extremely strong. Its boiling point and melting point are relatively low, due to the limited attractive force between molecules. Looking at its solubility, it has good solubility in organic solvents. Due to the principle of similar miscibility, its molecules have a certain degree of non-polarity, which is consistent with the non-polarity of organic solvents.
As for chemical properties, trialkyl methyl is highly reactive. The valence state and structure of its central atom make it easy to participate in various reactions. For example, in nucleophilic substitution reactions, it can be used as an electrophilic reagent, which is easy to attract nucleophilic reagents due to the density distribution of electron clouds around the central atom. In some free radical reactions, it can produce stable free radical intermediates, which can then participate in chain reactions.
Re-describe tetragonal photomethylborane. Its structure is centred on tetragonal borane and is associated with photomethylene. In terms of physical properties, it may be solid, and its appearance and color may vary due to factors such as impurities. Its melting point is relatively high, indicating that the intermolecular force is strong and the structure is relatively stable. In terms of solubility, it may have a certain solubility in some polar organic solvents, but its solubility law is more complicated than that of non-polar organic solvents, because there are both polar and non-polar parts in the molecule.
Chemically, tetragonal photoboranes have unique reactivity. The photoboranes can make molecules sensitive to light, and can initiate special chemical reactions under light conditions, such as photoisomerization. The structural part of boranes, due to the lack of electronic properties of boron atoms, is prone to react with electron-rich reagents to form new chemical bonds, showing rich chemical changes.
In conclusion, although trialkyl methyl and tetragonal photoborane are both chemical substances, their physical and chemical properties are quite different due to structural differences, and each has its own unique value and use in chemical research and practical applications.

According to the state of the market, the price of di- (trihydroxymethyl) -4-pentenolactone is difficult to be fixed, and it often changes with the times. In the past, the market was calm, supply and demand were combined, and its price was still stable. Each catty was about a hundred dollars. It was circulated in the market at a fair price, and all parties could profit. Businesspeople were happy to operate, and users felt that it was suitable.
However, things are impermanent. If the weather is unfavorable, the production of raw materials decreases sharply, or in case of human accidents, such as tax increases and obstruction of trade routes, resulting in poor supply of this product, the price will rise. At that time, the price per catty was more than 200 yuan, and everyone sighed at its high price. Users also need to measure and use it, and dare not spend lightly.
If by chance, the skills are advanced, the output is greatly increased, and the four parties come to the business, and they gather here, the supply exceeds the demand, and the price tends to drop. At this time, or each catty drops to about fifty dollars, the merchants compete to reduce the price in order to get rid of them. Although the profit is thin, they also hope to sell quickly to get back to their original.
As for the moment, the market is changing, and the situation is unpredictable. Its price hovers roughly between eighty and one hundred and fifty dollars. Looking at the situation, if there is no big change, it is expected that in a short period of time, the price will still fluctuate in the range. However, things in the world are unpredictable. The market is impermanent, and the rise and fall of prices are difficult to predict. It is difficult to predict, but when times change, we can see the future situation.

Trimethylmethyl-tetragonal light-methyl silicone oil is a matter of chemical substances, and its safety cannot be ignored.
Trimethylmethyl-trimethylmethyl-trimethylmethyl-trimethylmethyl-trimethylmethyl-trimethylmethyl-trimethylmethyl-trimethylmethyl-trimethylmethyl-trimethylmethyl-trimethylmethyl-trimethylmethyl-trimethylmethyl-trimethylmethyl-tetramethylmethyl-silicone-trimethylmethyl-tetramethylmethyl-tetramethylmethyl-silicone-trimethylmethyl-trimethylmethyl-trimethylmethyl-tetramethylmethyl-tetramethylmethyl-silicone-trimethylmethyl-trimethylmethyl-trimethylmethyl-trimethylmethyl-trimethylmethyl-trimethylmethyl-trimethylmethyl-trimethylmethyl-trimethylmethyl-trimethylmethyl-trimethylmethyl-trimethylmethyl-trimethylmethyl- It is advisable to wear gloves, glasses, etc. If it is accidentally damaged or enters the eyes, quickly wash it with a lot of water, or in the case of severe cases.
As for the square-shaped light methyl silicone oil, its properties are not determined, but it should not be ignored for safety. At the same time, you need to pay attention to the environment where it exists. It is advisable to be dry, dry, and oxidized. Because if it is subject to high shadow, sexual or emotional damage, it should be used, or it may be dangerous.
If you use it, operate according to the standard. For different purposes, there are different methods, so do not change it without authorization. And store it properly to prevent leakage and pollute the environment.
In addition, these two are related to safety matters, involving communication, fire prevention, protection, storage, and operation. Those who work together must be concerned with their hearts in order to ensure safety and security.
