PROBLEM TO BE SOLVED: To provide a method of purifying styrenes, capable of industrially advantageously removing phenylacetylenes contained in styrenes. SOLUTION: This method for purifying styrenes comprises subjecting phenylacetylenes to hydrogenation reaction without feeding hydrogen-containing gas from the outside by utilizing hydrogen dissolved in styrenes produced in dehydrogenation reaction of ethylbenzenes as hydrogen source in a method for subjecting phenylacetylenes contained in styrene to hydrogenation reaction to remove phenylacetylenes. |
