titleOfInvention | Process for producing styrene |
abstract | The invention relates to a process for the preparation of styrene or substituted styrenes comprising the steps of:n (a) subjecting a feed containing 1-phenyl ethanol or substituted 1-phenyl ethanol to a dehydration treatment in the presence of a suitable dehydration catalyst; (b) subjecting the resulting product mixture to a separation treatment, thus obtaining a stream containing water and styrene or substituted styrene and a residual fraction containing heavy ends; (c) treating the stream containing water and styrene or substituted styrene with a base; (d) separating the treated stream of step (c) into a styrene or substituted styrene-rich product stream and a styrene or substituted styrene-lean waste water stream; (e) treating the styrene or substituted styrene-lean waste water stream with steam in a stripping column, thus obtaining a treated waste water stream and a treated stream comprising steam and styrene or substituted styrene. |
