PRODUCTION OF 1,3-BUTADIENE

摘要

Olefins and diolefins, such as 1,3-butiadiene, may be produced by a method utilizing a series of bromination and dehydrobromination reactions. Bromine may be reacted with n-butane to form dibromobutane. The dibromobutanes may be dehydrobrominating to form 1,3-butadiene. The method may include reacting butene with bromine to form bromobutenes, and dehydrobrominating the bromobutenes to form 1,3-butadiene. The method may include reacting butene with hydrogen bromide in the presence of oxygen to form bromobutenes, and dehydrobrominating the bromobutenes to form 1,3-butadiene. The method may include reacting butene with bromine to form dibromobutanes, and dehydrobrominating the dibromobutanes to form 1,3-butadiene.

主权项

1. A method comprising:
reacting n-butane with bromine in one or more bromination reactors to form a bromination product stream comprising dibromobutanes; and subjecting the dibromobutanes to dehydrobromination in a dehydrobromination reactor to form a dehydrobromination product stream comprising 1,3-butadiene.
