1 - [ (3,4 - diethylphenyl) ethynyl] - 4 - isopropylbenzene, this is an organic compound. Its physical properties are quite important, let me tell you in detail.
Looking at its appearance, under room temperature and pressure, it is mostly colorless to light yellow liquid form. This form is convenient for participating in various chemical changes in many reaction systems. Because of its good fluidity, it is easy to contact and collide between molecules, and then promote the reaction process.
When it comes to the boiling point, the boiling point of this compound is about a certain temperature range. The level of boiling point depends on its performance in distillation, separation and other operations. A higher boiling point means that during the heating process, it needs to reach a specific temperature to convert it into a gaseous state, so as to achieve phase separation from other substances with different boiling points, which is of great significance in the purification process of chemical production.
Melting point is also one of its key physical properties. Under specific melting point conditions, the compound will change from solid to liquid. This property plays an extraordinary role in the identification and purity detection of substances. If the melting point of the sample is consistent with the theoretical value, it can be preliminarily determined that its purity is high.
The compound has a specific value in terms of density. The size of the density affects its distribution in the mixed system, and this property is an important consideration for processes involving liquid-liquid separation or phase equilibrium.
In terms of solubility, 1- [ (3,4-diethylphenyl) ethynyl] -4-isopropylbenzene is soluble in some organic solvents, such as common toluene, dichloromethane, etc. Good solubility makes it can be used as a reactant or product in organic synthesis, and it can be easily reacted in homogeneous systems, which greatly expands its application range in the field of organic chemistry.
In addition, its refractive index also has specific values. As a characteristic constant of substances, refractive index is often used in analytical chemistry to identify the purity and concentration of substances. By measuring refractive index, many important information about the compound can be obtained.

The chemical substance is 1 - [ (3,4 - diethylphenyl) isopropyl] - 4 - isopropylbenzene. To know whether its chemical properties are stable, many factors need to be considered.
Among this compound, the benzene ring structure has unique stability. The benzene ring is connected by six carbon atoms conjugated to a large π bond to form a closed conjugate system. According to Hueckel's rule, a planar cyclic conjugate system with (4n + 2) π electrons presents aromatic properties, while the benzene ring conforms to this rule, has high stability, and is not prone to reactions such as addition and oxidation.
However, the benzene ring of this compound is connected with alkyl groups. The electron cloud density of the benzene ring can be increased by the induction effect and the superconjugation effect. The change of electron cloud density will affect the activity of the electrophilic substitution reaction of the benzene ring. Although the electrophilic action of the alkyl group makes the benzene ring more susceptible to attack by electrophilic reagents, the activity of the electrophilic substitution reaction is enhanced, but the overall stability of the benzene ring is not damaged.
The spatial structure arrangement of 3,4-diethylphenyl and 4-isopropylbenzene has an impact on the molecular stability. Larger substituents will cause a steric hindrance effect, and the molecule will adjust its conformation in order to reduce the spatial rejection. Although the steric hindrance may affect the intermolecular interaction and reactivity, it is not a determinant of the stability of chemical properties.
From a comprehensive perspective, the aromatic stable structure of the 1 - [ (3,4 -diethylphenyl) isopropyl] - 4 -isopropylbenzene phenyl ring is relatively stable. However, due to the presence of alkyl power supply and steric resistance on the benzene ring, under specific conditions, corresponding chemical reactions can also occur, but the whole is still quite stable.

To prepare 1 - [ (3,4-diethylphenyl) ethynyl] - 4-isopropylbenzene, you can combine it according to the following ancient method.
First take an appropriate amount of 3,4-diethylbenzaldehyde, place it in a clean reactor, add an appropriate amount of strong base, such as potassium tert-butoxide, and stir well. Then slowly add the refined magnesium acetylbromide Grignard reagent to maintain the reaction temperature at a low temperature, about - 20 ° C to 0 ° C. This process requires strict temperature control to avoid side reactions. After adding it dropwise, continue to stir for a few times to make the reaction sufficient. After this step, the intermediate of (3,4-diethylphenyl) ethoxyne can be obtained.
Then, transfer the obtained (3,4-diethylphenyl) acetylene alcohol intermediate to another reaction vessel, add an appropriate amount of concentrated sulfuric acid as a catalyst, heat up to 120 ° C - 140 ° C, and carry out dehydration reaction. During this process, pay close attention to the reaction process, adjust the temperature and reaction time in a timely manner, so that the intermediate can be successfully dehydrated and converted into (3,4-diethylphenyl) acetylene.
Take 4-isopropylbromobenzene, add an appropriate amount of magnesium chips, and use anhydrous ether as a solvent to initiate a Grignard reaction to obtain 4-isopropylphenyl bromide magnesium Grignard reagent. Mix it with the (3,4-diethylphenyl) acetylene prepared above, add an appropriate amount of transition metal catalysts, such as the complex of palladium chloride and triphenylphosphine, and react under the condition of heating and reflux. The temperature is maintained at 60 ℃ - 80 ℃. After several times of reaction, the target product 1 - [ (3,4-diethylphenyl) ethynyl] - 4 -isopropylbenzene can be obtained.
After the reaction is completed, the product can be purified by conventional post-treatment methods, such as extraction, washing, drying, distillation, etc., to obtain pure 1 - [ (3,4-diethylphenyl) ethynyl] - 4 -isopropylbenzene. Although the steps of this synthesis are complicated, each step has its own requirements and requires fine operation to obtain satisfactory yield and purity.

The price range of 1-% 5B% 283,4-diethylphenyl% 29 ethynyl% 5D-4-ethynylbenzene in the market is difficult to determine. The change in its price is influenced by various factors.
First, the price of raw materials has a great impact. The production of this compound requires specific raw materials. If the supply and demand of raw materials change, or the cost of mining and preparation changes, the price of the compound will be affected. If raw materials are scarce and demand exceeds supply, the price will rise; conversely, the supply exceeds demand, and the price may trend down.
Second, the method of preparation is also important. Different production methods have different costs. The method of high efficiency and low cost can reduce the production cost and make the price close to the people; the method of complexity and high consumption will increase the cost and the price will follow.
Third, the market demand is the key factor. In the fields of scientific research and industrial production, if the demand for this compound is strong and the supply is limited, the price will rise; if the demand is weak, the supply exceeds the demand, and the price may decline.
Fourth, the price varies depending on the manufacturer and brand. Well-known manufacturers, due to their excellent reputation and quality control, the price of their products may be high; new factories or unknown factories, for the market, the price may be lower.
However, ancient books are searched all over, but no exact price records have been found. Today, if you want to know its market price range, you can consult chemical product suppliers, trading platforms, or check relevant market survey reports to get a relatively accurate number.
