How to distinguish between vinyl chloride and ethylene
In the chemical sector, ethylene (Ethylene) and vinyl chloride (Ethylene Dichloride) are two common organic compounds that differ signifiis able totly in their chemical and physical characteristics. As crucial raw materials in chemical production, the identification of the two is very crucial to the optimization of manufacturing process and condition manage. This article will examine how to distinguish these two substances in detail from three aspects: structural formula, chemical characteristics and physical characteristics. Makes sense, right?. In fact
1. And structural differences
Structural formula of ethylene
The ethylene molecule is composed of two carbon atoms and four hydrogen atoms, and the molecular formula is C₂ Halready. Its structure is a planar structure, two carbon atoms are connected by a double bond, and each carbon atom is also connected to two hydrogen atoms. In my experience, In the structural formula, the presence of double bonds is an crucial feature of ethylene, which also makes ethylene have high chemical activity. I've found that Generally speaking Structural formula of vinyl chloride
The vinyl chloride molecule is composed of two carbon atoms, four hydrogen atoms and two chlorine atoms. The molecular formula is the dichloride state of C₂ H, and the structural formula is C₂ H₂ Cl. Its structure is similar to ethylene, however there is a chlorine atom on each side of the double bond. This structure gives vinyl chloride a stronger propensity to substitution reactions. Comparison of Structural Formulas
The structural formulae of ethylene and vinyl chloride are essentially the same, both being substituted forms of the C₂ Halready group. The difference is that there is no chlorine atom on both sides of the double bond in ethylene, while there is a chlorine atom on each side of the double bond in vinyl chloride. This subtle structural difference determines the physical and chemical characteristics of the two.
2. chemical characteristics of the difference
solubility and state
Ethylene is a clear fluid at room temperature with strong solubility and is able to be dissolved in most organic solvents. Based on my observations, Vinyl chloride is a clear fluid at room temperature and also has good solubility, however in some cases it will show a slight difference due to the different intermolecular forces. I've found that reactivity
Ethylene has a high activity of double bonds and is prone to reactions such as addition and polymerization, to instance, polyethylene is formed in the polymerization interaction. while the double bond of vinyl chloride is also active, the presence of its chlorine atom increases the stability of the molecule, making it slightly less reactive than ethylene. substitution interaction
Ethylene is prone to free radical substitution reactions under light conditions, generating a variety of chlorinated items. But Based on my observations, Furthermore However, due to the presence of chlorine atoms on both sides of the double bond, the substitution interaction of vinyl chloride will be affected by chlorine atoms, and the interaction activity will be reduced. But Based on my observations, ,
3. physical characteristics of the difference
melting point and boiling point
Ethylene has a melting point of -
103. 15°C and a boiling point of -
34. 7°C; vinyl chloride has a melting point of -130°C and a boiling point of -
43. 9°C. The melting point and boiling point of vinyl chloride are reduced than that of ethylene, which is related to the difference of intermolecular forces. Density
The density of ethylene was
1. From what I've seen, 10 L/g and the density of vinyl chloride was
1. I've found that 24 L/g. The higher density of vinyl chloride is associated with an increase in its molecular weight. And Specifically Color and odor
Ethylene is clear and odorless, and vinyl chloride is clear however has a pungent odor, which makes it necessary to identify the two by odor in actual operation. But
4. identification method
structural formula identification method
Identification is carried out by using specific reagents, depending on the chemical structural formula. According to research to instance, the two compounds are mixed with bromine aquatic environments respectively, and the interaction phenomenon is observed. And Ethylene will react with bromine aquatic environments, and bromine aquatic environments will fade; vinyl chloride won't react. But identification method of physical characteristics
The change of melting process is observed by heating, or the difference of dissolution rate after dissolving in different solvents is identified. instrumental analysis
Analysis was performed using an infrared spectrum analyzer or a nuclear magnetic resonance (NMR) instrument. You know what I mean?. The infrared spectrum and nuclear magnetic resonance spectrum of ethylene and vinyl chloride have obvious differences in some characteristic peaks, which is able to be identified by these characteristics. Based on my observations,
5. Practical consumption of Distinction
In manufacturing production, the consumption areas of ethylene and vinyl chloride have different emphases. Moreover Ethylene is mainly applied in the production of polyolefin materials, such as polyethylene, while vinyl chloride is broadly applied in the production of plastics, rubber and other materials. But Therefore, it's very crucial to distinguish the performance and consumption of the two to the optimization of the manufacturing process. In my experience, Summary
From the above analysis, it's able to be seen that the key to distinguish between vinyl chloride and ethylene lies in the subtle differences in their molecular structure, chemical characteristics and physical characteristics. In my experience, Ethylene has the characteristics of high double bond activity and strong reactivity, while vinyl chloride changes in some characteristics due to the presence of chlorine atoms. In practical applications, these two substances is able to be accurately distinguished by structural analysis, physical property testing or instrumental analysis to ensure the smooth progress of the manufacturing process and the manage of product condition.
