Butylene-isobutylene fraction

The butylene-isobutylene fraction obtained as a result of fractional distillation and further processing of petroleum products is a chemically active mixture with high polymerization ability. This makes it possible to use it as a raw material for the synthesis of high-quality elastomeric materials and specialized polymers.

Chemical structure and synthesis

The main components of the fraction:

• Isobutylene, with the formula C4H8 (2-methylpropene);

• Butylene, presented as linear or branched isomers with the formula C4H8.

This mixture is isolated during the cracking of oil fractions and subsequent fractional distillation, which allows the components to be separated by boiling point.

Physico-chemical properties

• Physical condition: Light gas, which, when liquefied, can be used as a raw material for polymerization.

• Boiling temperature range: The components have similar boiling points, which ensures a narrow fractionation range.

• Reactivity: High chemical activity due to the presence of double bonds, which makes the fraction suitable for catalyzed polymerization.

• Volatility: The fraction is characterized by high volatility and requires special storage and transportation conditions.

Application

• Polymerization: It is used to produce polyisobutylene– a material used in the manufacture of adhesives, sealants and rubber products.

• Raw materials for the synthesis of elastomers: It is used as the main component for the creation of synthetic lubricants and special rubbers.

• Chemical intermediates: It serves as the basis for the production of a number of other hydrocarbon compounds by subsequent chemical modification.

Conclusion

Butylene-isobutylene fraction is a valuable oil refining product that is in demand in the production of high-quality polymer materials. Its unique composition makes it possible to obtain products with improved performance characteristics, which is crucial for many branches of the modern chemical and automotive industries.
