How can we get isopropyl bromide from propylene
Answers
Propene is a byproduct of oil refining and natural gas processing. During oil refining, ethylene, propene, and other compounds are produced as a result of cracking larger hydrocarbons. A major source of propene is naphtha cracking intended to produce ethylene, but it also results from refinery cracking producing other products.
Propene can be separated by fractional distillation from hydrocarbon mixtures obtained from cracking and other refining processes; refinery-grade propene is about 50 to 70%.
A shift to lighter steam cracker feedstocks with relatively lower propene yields and reduced motor gasoline demand in certain areas has reduced propene supply.
On-purpose production methods are significant
On-purpose production technologies include:
The Phillips Triolefin and the Olefin Conversion Processes interconverts propylene with ethylene and 2-butenes. Rhenium and molybdenum catalysts are used. The conversion of ethylene and 2-butene to propylene is industrially practiced.
Propene yields of about 90 wt% are achieved.
- Perform dehydrohalogenation of isopropyl chloride using alcoholic KOH.
CH3-CH(Cl)-CH3 + KOH ---- CH3-CH=CH2 +KCl
