Butadiene is obtained from the C4 pyrolytic fraction in the process of extractive distillation in the presence of dimethylformamide solvent.


Butadiene is mainly used for manufacturing organic chemicals such as polybutadiene rubber (PBR), styrene butadiene rubber (SBR), acrylonitrile butadiene styrene (ABS) resins, styrene butadiene latexes (SBL) and adiponitrile, as well as many other industrial products.
