<P>PROBLEM TO BE SOLVED: To provide a method for efficiently removing phenylacetylene in a styrene monomer feedstock. <P>SOLUTION: There is disclosed a method for reducing the amount of the phenylacetylene in a styrene monomer feed stream. The method includes using a normal styrene polymerization inhibitor additive such as hydroxylamine injected into the styrene monomer feed stream immediately upstream of a phenylacetylene reduction reactor. <P>COPYRIGHT: (C)2011,JPO&INPIT |
