Process for purifying styrene monomer feedstock prior to polymerization

   
   

A process is disclosed which provides for the reduction of phenylacetylene levels in styrene monomer feedstreams, which process utilizes a normal styrene inhibitor additive, such as an hydroxylamine, injected into the styrene monomer feedstream immediately upstream of the phenylacetylene reduction reactor.

Een proces wordt onthuld dat de vermindering van phenylacetyleneniveaus in styreenmonomeer feedstreams voorziet, welk proces een normaal additief van de styreeninhibitor, zoals hydroxylamine gebruikt, die in het styreenmonomeer feedstream stroomopwaarts wordt ingespoten onmiddellijk van de reactor van de phenylacetylenevermindering.
