Butylene-butadiene fraction
The butylene-butadiene fraction obtained as a result of fractional distillation of petroleum raw materials is a valuable intermediate product in the production of synthetic rubber. The components contained in it demonstrate high reactivity, which makes it possible to use it to obtain various copolymers with specified physical and mechanical properties.
Chemical structure and synthesis
The fraction includes:
-
Butylienes, having the formula C4H8 (for example, 1-butylene and 2-butylene);
-
Butadiene, having the formula C4H6.
This mixture is obtained by separating oil by distillation or cracking, in which the products are separated by boiling points.
Physico-chemical properties
-
Physical condition: Light gas or a slightly liquefied fraction at moderate pressures.
-
Boiling temperature range: The components have close boiling points (around 0-5 °C), which determines a narrow fraction.
-
Chemical activity: Saturated with double bonds, therefore, the fraction is susceptible to polymerization reactions.
-
Colorlessness and characteristic odor: The mixture has a typical odor for light hydrocarbons.
Application
-
Raw materials for rubber synthesis: Used in the production of butadiene-sterophilic and copolymer elastomers.
-
Polymer raw materials: It is used in the creation of synthetic rubbers for the automotive and construction industries.
-
Chemical intermediate: It is used in subsequent polymerization and modification processes for the production of specialized formulations.
Conclusion
The butylene-butadiene fraction is an important component of petrochemical production used to create high–quality synthetic rubbers and elastomers. Its optimal physico-chemical properties make it possible to obtain materials with the required characteristics, which is of great importance for modern industrial production.
