Product Specifications


Butadiene, C4H6 - also known as 1,3-Butadiene, is a simple conjugated diene. It is mostly derived using an extractive distillation process from the Crude C4 stream. Most Butadiene is polymerized to product Styrene-Butadiene Rubber (SBR) used in manufacturing automobile tires. Other uses include the manufacturing of adhesives, sealants, coatings and rubber articles like shoe soles.

Raffinate-1 is a by-product from the process of extractive distillation of Crude C4. Crude C4 contains 55-60% of Raffinate-1, while the other portion being Butadiene. Raffinate-1 consists of Isobutylene, Butene-1, Butene-2 and small amounts of Butanes and other compounds. Isobutylene is the main feedstock to manufacture Methyl Tertiary Butyl Ether (MTBE) and Di-isobutylene (DIB).
