Organic chemists aim to separate alkenes such as ethylene and propene from alkynes before converting them into polymers. The technique has several drawbacks including hydrogenation of alkynes to produce unwanted alkanes, ...
Olefins are one of those molecule types that most people don't recognize, but which appear everywhere: in bottles, in medicines, in wetsuits and in tires. Now, University of Chicago chemists have discovered an efficient method ...

A team of chemists at the University of California has found a more efficient way to separate olefins from terpenes and similar compounds. In their paper published in the journal Science, the group describes the new approach ...
Olefins are simple compounds of hydrogen and carbon but represent the building blocks of chemistry, and are vital for the synthesis of materials from polymers and plastics to petrochemicals. However, olefin production requires ...
