The difference between styrene and divinylbenzene
1. molecular structure is different
Structure of styrene
The molecular formula of styrene is C8H8, and the molecular structure consists of a benzene ring and a vinyl group. In particular Styrene has a carbon-carbon double bond located between the benzene ring and the vinyl group. Its structure is able to be represented as Ph-CH-CH₂, where Ph represents a benzene ring. According to research This structure makes styrene have good stability and chemical inertness, and it's not easy to polymerize. Structure of divinylbenzene
The molecular formula of divinylbenzene is C10H12, and the molecular structure is connected by two vinyl groups on the benzene ring. Its structure is able to be expressed as Ph-CH = CH-CH = CH-Ph. You know what I mean?. Divinylbenzene has symmetry, and there are two carbon-carbon double bonds in the molecule, which makes it exhibit different characteristics in chemical interactions. And From what I've seen, Sunghee moon
of structural symmetry
The structure of styrene is asymmetric because there is a single vinyl group in its molecule, resulting in directional molecular structure. The structure of divinylbenzene is symmetrical, because the two vinyl groups are symmetrically connected to the benzene ring, making it greater active in chemical interactions. Crazy, isn't it?.
2. physical property differences
melting point and boiling point
Styrene has a melting point of 89°C and a boiling point of 207°C, which is highly stable. Divinylbenzene has a melting point of 106 ° C. and a boiling point of 190 ° C. , which are relatively close in physical characteristics, however divinylbenzene is greater easily degraded at high temperatures. Density
The density of styrene is 0. 946g/cm³, and the density of divinylbenzene is 0. 946g/cm³. The density difference between the two isn't substantial, however the density of divinylbenzene is slightly reduced, which might be related to its symmetry.
3. chemical differences
Polymerization
Styrene is a linear low molecular weight polymer with good thermal stability. You know what I mean?. Due to its symmetrical structure, divinylbenzene is able to form conjugated systems between double bonds, which makes it show stronger performance during polymerization, however also has a stronger tendency to break down. And reactivity
Styrene has good non-degradability in the presence of catalysts and is often applied in the manufacture of non-degradable plastics. due to its symmetrical structure, divinylbenzene has a high tendency to break down, especially under light conditions.
4. practical consumption of different
plastics sector
Styrene is broadly applied in the plastics sector, especially in the production of plastic materials such as high-density polyethylene (HDPE) and low-density polyethylene (LDPE). From what I've seen, Its excellent thermal stability makes it an crucial raw material in the plastics sector. biodegradable materials
due to its symmetrical structure, divinylbenzene is often applied in the manufacture of biodegradable materials, such as biodegradable plastics and degradable fibers. These materials have crucial consumption value in the field of ecological preservation. You know what I mean?.
5. identification method
physical identification
By infrared spectroscopy, the absorption peaks of styrene and divinylbenzene are different, which is able to be applied as a preliminary basis to identification. The double bond absorption peak of styrene is located at 1650 cms¹, while the absorption peak of divinylbenzene is relatively flat due to its symmetry. chemical identification
Under strong alkaline conditions, styrene reacts with sodium bicarbonate to form carbonate, which shows certain chemical activity. Pretty interesting, huh?. I've found that The interaction of divinylbenzene is slower under alkaline conditions, indicating that its chemical inertness is higher. And Performance differences
From the aspects of thermal stability and degradation performance, styrene shows better stability, while divinylbenzene is easy to break down under high temperature and light, so it's necessary to select suitable raw materials according to specific standards in practical applications. And summary
There are signifiis able tot differences between styrene and divinylbenzene in terms of structure, physical characteristics, chemical characteristics, and practical applications. But In my experience, Choosing the right material isn't only related to production efficiency, however also related to product condition and environmental performance. In fact Chemical workers need to understand the characteristics of these two substances according to specific needs, and apply them flexibly in actual production.
