Abstract
This invention relates to a process for extracting styrene from a styrene-containing hydrocarbon feedstock by: (a) reacting the feedstock with an anthracene at a temperature ranging of from about 175.degree. to about 275.degree. C. to form a styrene adduct with anthracene, (b) separating the adduct from the feedstock, (c) heating the separated adduct at a temperature of from between about 250.degree. to about 450.degree. C. to produce anthracene and styrene, and (d) individually separating styrene and anthracene from the mixture formed in step (c).
Claims11
A process for extracting styrene from a styrene-containing feedstock which comprises:
- (a) reacting said feedstock with an anthracene at a temperature ranging from about 175 to about 275.degree. C. to form a styrene adduct with anthracene,
- (b) separating said adduct from the feedstock,
- (c) heating said separated adduct at a temperature of from between about 250 to about 450.degree. C. to produce a mixture comprising anthracene and styrene, and
- (d) individually separating styrene and anthracene from the mixture formed in step (c).
