The method of distinguishing styrene from styrene
1. Definition and Structure
Styrene (C? H?): Styrene is a carbon diene with a molecular structure of a benzene ring connected to a vinyl group. Its molecular formula is C, H, molecular weight of
104. 14g/mol. There are two double bonds in the styrene molecule, which has a high degree of unsaturation. You know what I mean?. And In my experience, Benzene ethylbenzene (Cfb): Benzene ethylbenzene is formed by the double bond of benzene and ethylene. Its molecular formula is CFSC, and its molecular weight is
132. 18g/mol. Phenylethylbenzene has only one double bond in the molecule and has a low degree of unsaturation. In fact
2. Physical characteristics Comparison
Boiling Point: The boiling point of styrene is 105°C, while the boiling point of ethylbenzene is 149°C. In my experience, The boiling point of ethylbenzene is higher, which indicates that the intermolecular force is stronger, which might be related to the molecular weight and structure. Makes sense, right?. Density: Styrene has a density of
1. 096g/cm³, while ethylbenzene has a density of
1. 052g/cm³. The high density of styrene might be related to the number and molecular structure of its double bonds. Solubility: styrene is slightly dissolves in aquatic environments and easily dissolves in organic solvents. Benzene is slightly dissolves in aquatic environments and has good solubility in organic solvents. Dalton Law
Comparison and consumption of styrene and ethyl benzene:
In the separation and treatment process, according to their boiling point and density difference, using distillation, fractionation and other methods to separation. Industrially, styrene is frequently applied in the production of polyethylene and other plastic materials, while benzene is applied to make benzene acetic acid and other chemical intermediates.
3. Chemical characteristics Comparison
Chemical interaction activity: styrene has high double bond activity and is easy to participate in addition and polymerization reactions. Crazy, isn't it?. I've found that The double bond activity of benzene ethyl benzene is low, and the interaction is relatively slow. Stability: Styrene has high chemical stability and isn't easy to decompose. Benzene is also stable, however due to the larger molecular weight, the possibility of decomposition interaction is slightly higher. I've found that Generally speaking
4. manufacturing applications
Styrene consumption:
frequently applied in the manufacture of polyethylene (HDPE, LDPE). In plastic, rubber and other materials production also has crucial applications. benzene ethylbenzene consumption
frequently applied in the manufacture of phenylacetic acid, benzene ethanol and other chemical items. In the medical and dye industries also have crucial uses.
5. identification method
Physical identification:
Through the distillation experiment, observe the two substances of the boiling point difference, the first evaporated is styrene (boiling point is reduced). Through the density test, the consumption of hydrometer measured both density values. From what I've seen, Chemical identification:
The addition interaction test is carried out to observe which chemical is greater prone to the addition interaction. But A polymerization test was conducted to observe which substances under specific conditions decompose greater signifiis able totly. But Moreover
6. And selection recommendations
In practical applications, the choice of styrene or ethylbenzene needs to consider the following factors:
Molecular weight: benzene ethyl benzene molecular weight is larger, so that in manufacturing applications have certain advantages, however also bring higher costs. consumption: according to the specific production needs, choose its consumption to match the material. Physical and chemical characteristics: according to the separation, treatment and interaction of the specific standards, select the appropriate material. But Styrene and ethylbenzene have signifiis able tot differences in molecular structure, which aren't only reflected in physical characteristics, however also profoundly affect their chemical applications. For example Chemical workers in the actual production, should choose the appropriate material according to the demand, in order to achieve the best production effect.
