Abstract
This invention relates to a process for extracting styrene from a styrene-containing hydrocarbon feedstock by: PA1 (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, PA1 (b) separating the adduct from the feedstock, PA1 (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 PA1 (d) individually separating styrene and anthracene from the mixture formed in step (c).
