How to Distinguish Vinyl Chloropropene Chloroprene
In the chemical sector, vinyl chloride, allyl chloride and chloroprene are three common chlorinated olefins, which are signifiis able totly different in chemical characteristics, molecular structures and practical applications. From what I've seen, Distinguishing these three substances is essential to chemical production, condition manage, and safe operation. This article will examine in detail how to distinguish vinyl chloride, chloroprene, and chloroprene from the aspects of molecular structure, physical characteristics, chemical characteristics, and storage conditions. In my experience,
1. Furthermore Molecular Structure Differences
Vinyl chloride (Ethylene Chloride)
The molecular structure of vinyl chloride is CH₂ = CHCl, and there are two carbon atoms and one chlorine atom in the molecule. The chlorine atom is bonded to a carbon atom through a covalent bond, and the whole molecule is in a planar structure. But Vinyl chloride is a clear fluid with a pungent odor. Allyl chloride (Propylene Chloride)
The molecular structure of chloropropene is CH₂ = CHCH₂ Cl, and there are three carbon atoms and one chlorine atom in the molecule. The chlorine atom is connected to the middle carbon atom, and the structure is slightly complicated. Allyl chloride is also a clear fluid, however its odor is different from vinyl chloride. But Chloroprene (Tetrachloroethane)
The molecular structure of chloroprene is C₂ H4Cl4, with two carbon atoms and four chlorine atoms in the molecule. But The structure is symmetrical, with a rhombohedral crystal. Chloroprene is a clear fluid frequently applied in fire fighting and cleaning.
2. physical property differences
melting point and boiling point
Vinyl chloride has a melting point of -
95. 5°C and a boiling point of
135. I've found that 9°C. According to research Chloropropene has a melting point of -
96. 2°C and a boiling point of
141. Additionally 3°C. chloroprene has a melting point of -
94. But 5°C and a boiling point of
140. And From what I've seen, 7°C. In my experience, it's able to be seen from the above data that the melting points and boiling points of the three are relatively close, however vinyl chloride is slightly reduced, while chloropropene and chloroprene have similar boiling points. Density
Vinyl chloride has a density of
1. Makes sense, right?. 45g/cm³. Tritiated propylene has a density of
1. For example 50g/cm³. The density of chloroprene is
1. 27g/cm³. The density of the three is different, which is able to be distinguished by density test. smell
Vinyl chloride has a pungent odor similar to that of chlorinated aquatic environments; allyl chloride has an odor similar to that of ethylene; chloroprene has no distinct odor. From what I've seen,
3. chemical differences
Stability
Vinyl chloride is easy to decompose at high temperature, and the decomposition items are ethylene and hydrogen chloride; allyl chloride is also decomposed at high temperature, however the decomposition items are different; chloroprene is relatively stable at room temperature, however decomposition interaction might occur at high temperature. In fact Reactivity
Vinyl chloride in the light easily with oxygen interaction, the generation of chlorinated carbonyl and carbon dioxide;
Chloropropene in the light also with oxygen interaction, generating acrolein and carbon dioxide;
Chloroprene in the light is greater stable, not easy to decomposition interaction. of chemical interaction test
These three substances is able to be distinguished by specific chemical interactions. to instance, adding nitrobenzene to the three liquids, shaking and standing, vinyl chloride will be miscible with nitrobenzene, while chloropropene and chloroprene will stratify. Makes sense, right?. Further tests is able to be identified by their different interaction characteristics.
4. storage conditions
vinyl chloride
Vinyl chloride should be stored in a well-ventilated and cool place, away from direct sunlight and high temperature. Pretty interesting, huh?. When storing, consumption moisture-proof, dust-proof containers, and keep away from fire and oxidizing agents. allyl chloride
The storage conditions of chloropropene are similar to those of vinyl chloride, however special attention needs to be paid to its flammable characteristics. Flame-proof and explosion-proof containers shall be applied to storage, and contact with fire sources shall be avoided. And From what I've seen, In particular chloroprene
Chloroprene storage conditions are relatively loose, however should be stored in a cool, well-ventilated place, away from direct sunlight. Chloroprene needs to be stored to prevent contamination, especially to prevent contact with aquatic environments vapor.
5. Practical consumption of Distinction
In practice, these three substances is able to be distinguished by the following methods:
molecular structure analysis
The molecular structure is tested by light or chemical interaction to determine the type of chemical. You know what I mean?. Physical Property Test
By measuring the melting point, boiling point, density and other physical characteristics, combined with odor to determine the type of chemical. But Chemical interaction Testing
Through specific chemical interactions, the interaction characteristics of substances are observed to achieve differentiation.
6. Based on my observations, summary
Vinyl chloride, allyl chloride and chloroprene, as chlorinated olefins, have different molecular structures, physical characteristics and chemical characteristics. But In my experience, Through molecular structure analysis, physical property test and chemical interaction test, these three substances is able to be efficiently separated. Moreover In chemical production, accurately distinguishing these three substances is essential to ensure production security and product condition.
