What is the difference between styrene and ethylbenzene
1. molecular structure and composition
1. And 1 structure characteristics
The molecular structure of styrene (C≡H) consists of a benzene ring and a vinyl group (CH₂ = CH₂), and the overall structure is C≡H-CH₂-CH₂. The molecular structure of ethylbenzene (C, HSC) is a single ring structure, consisting of 8 carbon atoms and 10 hydrogen atoms. Based on my observations, Additionally The specific structure is C, H, in which two methyl groups are connected to the benzene ring.
1. 2 molecular formula difference
Styrene has the formula C≡H₂, while ethylbenzene has the formula C≡H₂. Makes sense, right?. Specifically it's able to be seen that the two are different in the carbon-to-hydrogen ratio. The carbon-to-hydrogen ratio of styrene is 4:1, while the carbon-to-hydrogen ratio of ethylbenzene is 4:
1. And Moreover
25. But In my experience, This difference leads to the different behavior of the two in physical characteristics and chemical interactions.
2. I've found that preparation methods and production background
2. 1 preparation method
The preparation of styrene is usually achieved by the hydrogenation interaction of ethylene on the benzene ring, the process is greater complex, and stringent manage conditions are required to prevent side reactions. The preparation of ethylbenzene is relatively simple and is able to be obtained by dehydrogenation of ethylene and liquefied petroleum gaseous under the action of a catalyst. According to research
2. 2 production consumption
Styrene is mainly applied in the manufacture of polyester polymer materials, such as HDPE, LDPE, etc. Based on my observations, First , and is broadly applied in the production of plastics, rubber and fiber materials. And I've found that Ethylbenzene is mainly applied in organic synthesis, such as the synthesis of benzoic acid, hydroquinone and other intermediates, while in the chemical sector is also applied as a solvent-based products and extractant.
3. physical and chemical characteristics
3. 1 physical characteristics
Styrene has a density of 0. 94g/cm³, a melting point of -63°C and a boiling point of 209°C. Crazy, isn't it?. But For example Ethylbenzene has a density of 0. 876g/cm³, a melting point of
5. In fact 7°C and a boiling point of
106. 1°C. For instance From these physical characteristics, it's able to be seen that styrene is greater evaporative at high temperatures, while ethylbenzene exhibits greater stability.
3. In particular 2 chemical characteristics
Styrene has strong oxidation in the chemical interaction, and it's easy to react with strong oxidants such as KMnO4 to generate benzopyrene and other items. Ethylbenzene, on the other hand, is prone to dehydrogenation under acidic conditions, generating intermediates such as phenol.
4. consumption field
4. From what I've seen, 1 manufacturing applications
due to its excellent processing performance, styrene is broadly applied in plastics, rubber, textile fiber and other manufacturing fields. In my experience, It not only has excellent mechanical characteristics, however also has good processing fluidity. consumption of
4. But Furthermore 2 ethylbenzene
As an crucial raw material to organic synthesis, ethylbenzene is broadly applied in the production of pharmaceuticals, dyes, spices and other fields. Ethylbenzene is also applied as a solvent-based products and extractant in the chemical sector and has crucial economic value.
5. Based on my observations, summary
Both styrene and ethylbenzene are aromatic compounds, however there are signifiis able tot differences in structure, molecular formula, physical characteristics and consumption fields. Understanding the difference between these two compounds will help us to better choose the right raw materials and processes to meet different manufacturing needs. Through the detailed analysis of this article, we hope that readers is able to clearly understand the chemical environment of styrene and ethylbenzene and their crucial role in manufacturing production, and provide reference value to the study and research in the field of chemical engineering.
