Method to purify alpha-methyl styrene prior to catalytic hydrogenation |
摘要 |
Alpha-methyl styrene, obtained as a byproduct in the manufacture of phenol is hydrogenated to cumene using hydrogen and standard hydrogenation catalysts which are selective for the ethylenic side chain. Prior to hydrogenation the alpha-methyl styrene is treated to effect removal of hydroxy acetone present. By reducing or eliminating hydroxy acetone, poisoning of the catalyst is prevented. Hydroxy acetone is removed from the alpha-methyl styrene by catalytic pretreatment.
