Process for enriching cis or trans-isomers in an olefin stream

   
   

An olefin product rich in cis- or trans-isomers can be produced by reacting the mixed olefin feedstock with an linear polyaromatic compound such as anthracene under heat, then separating the unreacted olefin enriched in cis-isomer. The remaining linear unreacted polyaromtic compound and the polyaromatic compound-olefin adduct can be heated to dissociate the adduct to linear polyaromatic compound and olefin stream enriched in trans-isomer.

Los ricos de un producto del olefin en cis- o trans-isomers pueden ser producidos reaccionando la materia de base mezclada del olefin con un compuesto polyaromatic linear tal como antraceno bajo calor, después separando el olefin unreacted enriquecido en cis-iso'mero. La aducción compuesta y polyaromatic polyaromtic unreacted linear restante del compuesto-compound-olefin se puede calentar para disociar la aducción a la corriente polyaromatic linear del compuesto y del olefin enriquecida en trans-isomer.
