1% 2C4-ethylphenylacetylene is an organic compound with special physical properties. It is mostly liquid at room temperature, transparent in color and has a certain fluidity. Due to the influence of intermolecular forces, it has a specific viscosity, and needs to overcome internal friction when flowing.
Looking at its phase state, the melting point and boiling point are the key properties. The melting point determines the temperature from solid state to liquid state, and the boiling point is the temperature from liquid state to gaseous state. 1% 2C4-ethylphenylacetylene has a low melting point and condenses into a solid state at a specific low temperature; the boiling point is relatively moderate, and the gas, liquid and solid three-state transition can be realized at a certain temperature range. This property has a great impact on material separation, purification and storage.
In terms of solubility, because it contains benzene ring and ethynyl group, it is a non-polar or weakly polar molecule. According to the principle of "similar phase solubility", it is easily soluble in organic solvents, such as ethanol, ether, benzene, etc., which can be uniformly dispersed to form a solution; in water, because water is a strong polar solvent, it has little force with 1% 2C4-ethylphenylacetylene molecules, so it is difficult to dissolve.
1% 2C4-ethylphenylacetylene has a smaller density than water. If mixed with water, it will float on the water surface and form a stratification phenomenon. The upper layer is 1% 2C4-ethylphenylacetylene, and the lower layer is water. This property can be used as a basis for the separation and identification of mix
In addition, the compound is volatile to a certain extent, and it will evaporate slowly in the air, emitting a special odor. Its volatility is related to factors such as temperature, surface area, and air flow. When the temperature is high, the surface area is large, and the air flow is fast, the volatilization speed will be accelerated. This property should be paid attention to when using and storing, and it should be placed in a cool and ventilated place to prevent its rapid volatilization from causing losses or causing safety problems.

1% 2C4-dimethylphenyl ether, this material property is stable. It has a symmetrical structure, and the intermolecular force is suitable, so it is stable.
1% 2C4-dimethylphenyl ether, which is connected by the dimethyl group on the phenyl ring, has a symmetrical structure. Because of its symmetry, the molecular charge distribution is uniform, the interaction between molecules is balanced, and the external force is difficult to disturb its state. Such as the beam of a building, the structure is stable, and the building is safe.
Furthermore, its chemical bonds can be adapted. Carbon-carbon bonds, carbon-hydrogen bonds and other bonds have considerable energy, and it takes huge energy to break this bond. In the common temperature and pressure environment, the external energy is difficult to reach the threshold of breaking the bond, so the molecular structure is constant and the chemical properties are stable. Under daily conditions, it is not easy to react with other things. It is like a hermit. It is noisy and not surprised, and keeps its inherent nature.
And methyl is the power supply radical, which can fine-tune the distribution of benzene ring electron cloud and enhance the stability of benzene ring. The optimization of electron cloud distribution makes the molecule more resistant to external chemical attacks. Like a strong shield, it can defend against the enemy and ensure the stability of the molecule.
In summary, 1% 2C4-dimethylphenyl ether is chemically stable, and its structure and properties can be maintained in common environments.

In the preparation of 1% 2C4-dimethylnaphthalene in the chemical industry, the following things need to be careful:
The purity of the first raw material. In the synthesis of 1% 2C4-dimethylnaphthalene, the purity of the raw material is essential. Impurities exist in the raw material, or the reaction is skewed, the product is impure, and the quality is not up to the desired. If naphthalene and methylating reagents are used as raw materials, if the naphthalene contains impurities, or side reactions occur during the reaction, the yield of the target product will decrease. Therefore, before the raw material enters the reaction, it should be refined and purified to maintain its purity.
The article of secondary control reaction. Temperature, pressure, and catalyst are all factors that affect the reaction. Temperature is related to the reaction rate and product distribution. Temperature is low, the reaction is slow, and the yield is difficult to be high; high temperature, or side reactions, damage the target product. Pressure is also critical, and appropriate pressure can promote the reaction to produce 1% 2C4-dimethylnaphthalene. And the catalyst can change the chemical reaction rate, choose a catalyst with high activity and good selectivity, which can increase the reaction efficiency and product purity.
Furthermore, anti-fouling and safety. In the preparation of 1% 2C4-dimethylnaphthalene, or use toxic and harmful reagents, when operating, strictly follow safety regulations and take protective measures, such as working in a fume hood, wearing protective clothing, gloves, masks, etc., to prevent the human body from contacting with harmful substances. And the waste generated by the reaction should be handled in accordance with environmental protection regulations, and should not be discarded at will to avoid polluting the environment.
Also check the condition of the equipment. Whether the reaction equipment is good or not depends on whether the reaction can proceed smoothly. Regularly check the equipment to ensure its tightness and no risk of leakage. And the material of the equipment, when compatible with the reactants and products, prevents corrosion and causes equipment damage, which affects production.
The importance of final monitoring. When the reaction process is monitored in real time, the reaction strip can be adjusted in time. Chromatography, spectroscopy and other analytical methods can be used to measure the concentration change of each substance in the reaction system, the progress of the reaction, and the reaction can be stopped at an appropriate time to obtain a high-quality 1% 2C4-dimethylnaphthalene product.

1% 2C4-dimethylbenzene is p-xylene, and its market price often fluctuates due to various factors, making it difficult to give an exact fixed value.
In the past, the price of p-xylene was influenced by supply and demand, raw material costs, and market conditions. When crude oil prices are high and downstream industries such as polyester industries have strong demand, their prices tend to rise; if production capacity increases sharply, demand is sluggish, and prices are prone to fall.
In recent years, the price of p-xylene has roughly fluctuated between thousands and 10,000 yuan per ton. If the market supply is abundant and the demand is slightly slower, the price may be around 7,000 to 8,000 yuan per ton; however, when the market supply and demand tighten, especially the downstream polyester industry is expanding rapidly and the demand is strong, the price may rise to more than 10,000 yuan per ton.
Over the past few years, the price of paraxylene has been tortuous due to the global economic situation, industry policies, emergencies, etc. In order to know its accurate market price, it is necessary to check the chemical market information, industry reports, etc. in real time to get the current exact price.
