Question

How will your prepare propene from propyne?

Answer 1

Answer

If one has some understanding of the nomenclature of organic molecules, then the difference propane and propene, is that there a double bonds between carbons in propene, while the carbons in propane a single bonded and a a straight chain. Propane has 3 carbons and 8 hydrogens, while propene has 3 carbons a 4 hydrogens, and might be a cis- , trans-, levo-, or dextro, depending on the positions of the hydrogens on the two end carbons. Production is done via the very tall cracking tower at the refinery. Propene has a different density, than Propane, so it will show up at a different level with the tower. If it comes mixed with other gases of nearly the same density, then separation is often done through liquefaction via compression, as the temperature of vaporization is most likely to be of a greater difference. Forming double bonds between carbons from straight chained organics is a long chapter in a Organic Chemistry Book.
